ZyXEL Communications Corp. edited by Manfred Recla February 5, 1997 Release note for Elite 2864I version 2.05b (public betatest !) ============================================================== Fixed Bugs: ----------- 1. Set baud rate as 19200/9600/4800/2400 bps, key in T<CR>AT<CR>... sequence there will be no response from TA. 2. AT&F doesn't update AA LED status. 3. For USA version, if switch type is AT&T point-to-point, sometimes layer 1 can not activate. 4. For USA version, if switch type is NI1, callback function does not work. 5. CAPI 2.0 driver can not be used with CANDI. 6. Issuing "ATC$" to view EPA will get some garbage. 7. Plug & play function does not work with Win95. 8. The modem call will be disconnected through Minitel switch. New Implementation: ------------------- 1. AT*GC1: 2 changes: 1.1. Compare Calling Party Number (CPN) with the stored numbers from the right digit to the left digit. So 8005552000 will match 5552000. 1.2. Based on the shorter one, so the CPN can be longer or shorter than the stored numbers. 2. Leased line function. Using following commands to configure: 2.1. ATDCn n=1,2,3 excites leased line connection on originate mode. DC1 - excites leased line connection using B1 channel on originate mode DC2 - excites leased line connection using B2 channel on originate mode DC3 - excites leased line connection using both B1 and B2 channel on originate mode 2.2. ATABn n=1,2,3 excites leased line connection on answer mode. AB1 - excites leased line connection using B1 channel on answer mode AB2 - excites leased line connection using B2 channel on answer mode AB3 - excites leased line connection using both B1 and B2 channel on answer mode 2.3. AT&In n=0,1,2,3 normal/leased line options &I0 - normal dial-up phone line. (default) &I1 - leased line function in B1 channel only, dial-up function in B2 channel &I2 - leased line function in B2 channel only, dial-up function in B1 channel &I3 - leased line function in both B1 and B2 channel. ---------------------------------------------------------------------------- Dec. 31, 1996 Release note for Elite 2864I version 2.05a (public betatest !) ============================================================== Fixed the Bugs: --------------- 1. For AOC function, a second call deletes the charging information from channel B1, but not really: After the next charging unit comes for B1 channel, the lost units shows correctly again and the A/B adapter send this accumulated units as 16 kHz metering pulse to the connected phone. By the way, the phone displayed wrong charging information. 2. Issuing "ATS103=n&L0S0=0 (n>0), when number n expired and incoming call routed to fax/modem, there is no ring tone. 3. It's necessary to analysis the High-Layer Compability information element, especilly G4 fax, an incoming call with G4 fax should be routed to internal modem. 4. After issuing "AT+FCLASS=x", x = 0,1,2,6,8,Z, the first loopback command ( AT&T1 or AT&T8 ) will get "ERROR". 5. Issuing "AT&F" and "AT+FCLASS=8", the VO led will be lighted up: 1) Issuing "ATZ", the VO led is still on and FCLASS still equal 8. 2) Issuing "AT&F", the VO led is still on but FCLASS reset to 0. 6. The Elite 2864I can not accept "*" in dial string, it's necessary for dialing a phone number. 7. While one B channel is connecting with a data call which protocol is different from the setted outgoing protocol, then making an analog call via issuing "ATDBxxxx". After getting "CONNECT" message, issue "ATO" may get wrong protocol ( same as setted outgoing protocol ) in connection message. Then after a few minutes, the Elite will reset. 8. For s50 function, while the value of s50 is more then 128, making a data call will cause modem reset. 9. The answer side sets "ATE0Q1" "AT*G4" or "AT*G5". while calling back a incoming call ,the message "CallBack ATDIS0" will be displayed. 10. Issuing "ATI3I3", the second link status message dose not display completely. 11. For UK version, while making a phone call can not get dial tone & ring back tone. 12. Fixed the bug in the comformance test of Singapore. 13. The modem will crash when the server reguest PAP but Win95 require encrypted password. 14. For PPP/MP, the second call will wait 2 seconds to dial out after the first passes authentication. 15. Issuing "ATCG", the activated of layer 1 fails. 16. For s124 setting, there are some problems to send LCP-echo. 17. The timer for S124 value is incorrect to send LCP-echo. Newly Implemented: ----------------- 1. AT&M3: synchronous mode. AT*I1: V25Bis command set. It's necessary to issue "AT&M3" and "AT*I1" together for V25bis dialer of synchronous mode. At call site, issue "ATB11" ( V.110, sync 64K ), then LLC with sync mode will be included in the SETUP message. At answer site, the Elite will check LLC of incoming SETUP message and connect with sync data. 2. A public betatest version of the CAPI 2.0 driver for Windows (CAPI.DLL, 16-bit) was released simultaneously with this F/W version. The supported B-channel layer 2 and layer 3 protocols are: X.75/transparent X.75/T.70 (for T-Online), X.75/ISO8208 (for European File Transfer) HDLC/transparent Bit Transparent (for some G3 Fax applications). Two applications on the same PC can work concurrently, each using one of the two B-channels. 3. Autodetecting protocols for outgoing calls. 4. Changing switch type of USA from S86 of user profiles to two bytes in NVRAM. the definition of S86 would be defined in the future. 5. S50, inactivity timer. The Elite counts when there is no data flow in or out of the RS-232 serial port. A connection is disengaged when the counter reaches the preset value. Set '0' to disable this function. This function is available in PPP protocol. Known bugs of version 2.05a: --------------------------- 1. V.110/38k4-8n1 compatibility problem with "CITAM" ISDN-TA. The German product "CITAM" uses another version of Siemens V.110 chip. 2. The problem of receiving fax to DRAM: while setting "AT+FZF=3" (or 5), the serial cable is disconnected and DTE speed with which previous cpmmands have been entered is more than 230.4 Kbps. An incoming call fax can not route to DRAM and then disconnect the call. 3. AT+FZA causes the Elite to hang (power off/on must be done to get the Elite into the command idle mode again) ----------------------------------------------------------------------------- Release Note on Elite 2864I Version 2.05 December 18, 1996 ======================================== Fixed the Bugs: -------------- 1. For CAPI mode, the EAZ to MSN mapping on incoming call does not work. 2. For BACP/BAP of PPP, the Elite can not dial second number. 3. For BACP/BAP of PPP, the Elite causes the remote side not able to dial the second number. 4. For PPP/MP, sometimes the Elite can not do the second B channel negotiation. 5. For PPP/MP, if remote side drops B1 channel, then the Elite will drops the B2 channel automatically. 6. For CCP/STAC sequence mode of PPP, the Elite crashes during the negotiation. 7. For PPP/MP, LCP's negotiation fails while answering a incoming call. 8. Now ISO8208 of CAPI 1.1 Profile A is rigid. 9. For PPP/MP, the Elite may crash while hangup sometimes. 10. For PPP/MP, the second B channel negotiation may fail sometimes. 11. For PPP/MP, CCP/STAC does not work with Cisco's routers. 12. DSR handling does not work correct. 13. S35.1 - disable aborting from terminal during modem handshaking - does not work. 14. For CAPI mode, EAZ to MSN mapping function. If one MSN is assigned for a/b adapter ( AT&ZI7=..... ) and the same MSN is assigned for the EAZ to MSN mapping with AT&Zn=....., then an incoming digital call for this MSN won't be mapped. New Implemented: ---------------- 1. For CAPI mode, added HDLC protocol for B channel. Users can select it for PPP applications (e.g. WISDI or WISPA). 2. S50, inactivity timer. The Elite counts when there is no data flow in or out of the RS-232 serial port. A connection is disengaged when the counter reaches the preset value. Set '0' to disable this function. This function is available in B channel protocols X.75, V.120, or V.110. 3. Internal modem is version 1.14. -> please read seperate release notes. 4. For PPP, New AT commands for enable/disable BACP/BAP ATBP0 - disable BACP/BAP ATBP1 - enable BACP/BAP 5. Autoselection of 64kbps and 3.1 kHz on outgoing calls. Setting AT&O1 to enable this function. Issue ATDxxxx to make an outgoing call, the Elite may try to connect an ISDN call firstly and then a modem call if ISDN call can not connect successfully. Known bugs of version 2.05: --------------------------- 1. V.110/38k4-8n1 compatibility problem with "CITAM" ISDN-TA. The German product "CITAM" uses another version of Siemens V.110 chip. 2. For "cFos channel bundle" (CCB, "AT&J3S100=1") connection, during file transfer, pick up the phone and make a call then drop the phone call. The B2 channel will be reactived, but it encounters many bad CRC and file transfer will stop. 3. In the ESCAPE state ("+++") of a V.110 connection, issuing "ATI2" will disconnect the connection, while "AT&V" will cause CTS low. 4. For U model of USA version, A/B adater offhook will generate garbage during V.110 connection. 5. The problem of receiving fax to DRAM: while setting "AT+FZF=3" ( or 5 ), and the serial cable is disconnected and DTE speed with which previous commands have been entered is more than 19200 bps. An incoming fax can not route to DRAM and then disconnect the call. _____________________________________________________________________________ Release Note on Elite 2864I Version 2.04 ======================================== Fixed the Bugs: =============== * Placing a Call -------------- 1. S38.0=1 (repeatedly dial) and S44.3=1 (cyclic dial with "ATDSn" comamnd) don't work. 2. The analog call can not send LLC (Low Layer Capability) while set S80.4=1 or S80.7=1. 3. For USA version: if you make a bundle call and press any key on the keyboard to abort the call before the answer side has picked up, the B1 channel drops and a "NO CARRIER" message is sent, but the B2 channel is still up. You will get "RINGING" messages for the B2 channel after having received "NO CARRIER". * Voice Mode ---------- 4. Voice connection fails to send <dle><etx> at the end of the voice data stream. 5. Issue "AT+FCLASS=8;+VIP" get "ERROR" back, you can not have more than two voice commands on one line. 6. Using TRIO or ZFAX, call in the voice mail and the voice script will start playing as soon as the modem answers, but if you pickup the phone from the adapter the voice script will stop playing. * Internal Modem/FAX ------------------ 7. Setting the Elite to "AT+FZF=1", 4, or 5 with DTR off. The Elite will answer the modem call ( it should drop the modem call ). 8. For modem call connection, if one issues "+++", "AT&V", and "ATO" sequencially then no file can be transfered. 9. Sending a multiple page fax to the modem. If you pick up the receiver after the fax starts printing or during fax negotiation, the modem will not receive the fax properly. 10. When calling a V.FC modem almost all connects are without error correction. Dropping the DTR, the modem will reboot. 11. Set "AT+FZF=3" or "AT+FCLASS=Z" and make a modem call. The modem can not establish all connections. 12. Make a modem call and get "RINGING" message. Issuing "ATH" will create the wrong string "<cr><lf><lf>OK<cr><lf>OK<cr><lf>". * Security Functions ------------------ 13. Security function on V.110 doesn't work. 14. Set S35.6=1, then issue "AT&W", there is no request for password. 15. Set *G5 ( call back function ). the Elite will change outgoing service's setting after call back. 16. Enable security function, after call connection and need password in call site, we can send data from the answer site. 17. CD is raised while the prompt for "PassWord:" is sent using security function. CD should be raised only when the security checking procedure is finished and ready to transfer data. 18. The stored call back number ( by "AT*HCn" ) can not be erased by doing hardware reset. 19. For security functions there were two kinds of messages that could be used at the Elite prompt. For example, "Password" and "PassWord", "CORRECT" and "Correct". Now "PassWord" and "Correct" are the only correct messages. (U-1496 backward compatibility !) * Numerical Result Code --------------------- 20. Set DTE speed tp 38400 bps and dial "ATV0DMxxxx", you will receive the numeric connect code without CR. 21. Set "ATS35.7=1V0", then "AT&T9" will give a numerical result code "1", it should be "50". * V.110 ----- 22. After V.110 connection, the item "Receive Byte" of "ATI3" displays incorrect value. 23. V.110 connection problem with NOKIA 2110i. * PPP/SLIP -------- 24. For PPP/MP, improve file upload performance. 25. For PPP/MP, the Elite crashed durring stress tests. 26. "SLIP async to sync convertion" function did not work. Issue "ATB41" to set outgoing service = SLIP conversion. This AT command also set the Elite to use SLIP protocol to receive any data call. * Loopback Test ------------- 27. For U model of USA version, issuing "AT&T8" or "AT&T10" causes the Elite to loose the SPIDs. 28. After ISDN loopback test ( AT&T9, AT&T10 ) the Elite can not place an outgoing call on the first try. 29. If after ISDN loopback test ( AT&T9, AT&T10 ), an ISDN call comes in ( ex. X.75, V.120 ), the Elite will indicate a PPP connection message and soon after that "NO CARRIER". * a/b adapter (POTS Port) ----------------------- 30. You can not assign AT&Zn=bxxxxx for a/b adapter into NVRAM at location n, the letter 'b' can not be saved. 31. Unplug the ISDN line and dial ATDBxxxx, after "NO CARRIER" shows up, the first AT command can not be issued. After one <cr> a new AT command can be entered. 32. During handshaking for a fax call, if the a/b adapter is off-hook at the answer site the connection will fail. 33. If you set AT&D1*Dn&Zn=bxxx, then drop DTR will make an outgoing phone call. This function only works the first time while setting. Using drop DTR again will get no action. 34. During an incoming call to the a/b adapter (ringing state), issuing "ATH3" will not get any response. 35. Issue ATCM2 ( by ZyXEL's CAPI 1.1 profile A driver ), any incoming call and a/b adapter hook state change causes the Elite to malfunction. * AT Commands ----------- 36. Issuing "ATZI1" will get "ERROR", it should be "OK". 37. Elite generates responses with a bit parity error by using 7E1 format, For example: AT ---> echos "AT" 7E1 correct! ---> responses "OK" 8N1 produces a parity error. 38. Setting MSN continuously ( ex. AT&ZI2=0&ZI6=1<cr> ) will give an incorrect number. 39. For ISDN data connection: Issuing "+++" and "ATI2O" can go back to data state but can not transfer data. Issuing "+++" and "ATI3O" will display wrong message and then AT command will not work. * Answering a Call ---------------- 40. If you make a call to the Elite and the DTR is low, then wait for the modem to ring a few times and hang up the call before it connects. After that if you try to bring DTR high, the "buffered" RING messages will be sent to the DTE. * Miscellaneous ------------- 41. While receiving a Facility message with AOC_S, the Elite 2864I will send a STATUS message. 42. Connection problem with ELSA MicroLink ISDN TL/V.34: When the ELSA has V42bis handshaking activated ( which is default), the Elite disconnected immedeately. Now it will connect without data compression. Newly Implemented: ================== * Sync Data --------- 1. AT&M1: asynchronous (=async) command, synchronous (=sync) mode. At call site, issue "AT&M1" and "ATB11" ( V.110, sync 64K ), then LLC with sync mode will be included in the SETUP message. AT answer site, only issue "AT&M1", the Elite will check LLC of incoming SETUP message and connect with sync data. [Note]: V.25bis dialer for sync mode (AT&M3) will be released in the next firmware version v2.05. In the mean time, a test special version for V.25bis is available, please contact your local authorized ZyXEL distributor ! * CAPI.DLL v1.1 Profile A ------------------------ 2. A public betatest version of the CAPI 1.1 profile A driver for Windows (CAPI.DLL, 16-bit) was released simultaneously with the F/W version 2.04. The supported B-channel layer 3 protocols are: X.75 Transparent, T.70 (for T-Online), ISO8208 (for European File Transfer, see Note *), and Bit Transparent (for some G3 Fax applications, see Note *). [Note *]: These protocols are in the alpha test state and are still very buggy. Two applications on the same PC can work concurrently, each using one of the two B-channels. [Note] We established a public mailing list on the Internet for testing this CAPI.DLL. If you are interested, please subscribe to this mailing list: send an eMail to "majordomo@zyxel.co.at" and in the message body write following two lines: -------------------------------------------- subscribe capi-testers your.name@site.domain end -------------------------------------------- where "your.name@site.domain" is your full Internet eMail address. If you had subscribed successfully you will receive a confirmation of your subscription in an eMail within minutes. The "Welcome to the capi-testers mailing list" eMail contains more background information .... 3. EAZ to MSN mapping function for CAPI mode. Users can use AT&Zn=xxx/sss/, n=0-9 (denotes the EAZ), xxx = phonenumber, sss = subaddresss to do this mapping. For outgoing calls, the Elite receives "Source EAZ" (0-9) from the application and uses the appriopriate phone number as Calling_Party_Number/Subaddress. For incoming calls, the Elite checks Called_Party_Number/Subaddress and uses the matched phone number register's pointer (0-9) as "RequestedEAZ" to the applications. * Charging Information (new in EuroISDN "DSS1" firmware) ------------------------------------------------------ 4. AOC (Advice Of Charging) function: now you can use "ATCH?" to view the charge information of the last call if the network had sent the message. Please check with your ISDN Central Switching Office if any of the following EuroISDN supplementary services - according to the ETSI specifications - could be actived (because they are not supported in all European countries !) AOC-S/currency = Advice of Charging on call Setup time AOC-D/currency AOC-D/units = Advice of Charging During a connection AOC-E/currency AOC-E/units = Advice of Charging at the End of a call 5. Metering Pulse function ("ATS89.6=1") in case of the "AOC-D/units" ISDN supplementary service: for Germany (16 kHz), Switzerland (12 kHz) and Austria (12 kHz). Therefor it is necessary to set the correct ISDN country code ! Please check the current ISDN country code with the command "AT#H" [Note] Users can use the following command to change the country code: ATS38=4 for enable changing country code function. AT#Gxxx for enter country code xxx. ISDN country code list: Sweden 250 HongKong 242 Taiwan 238 Germany 237 Italy 236 Japan 234 Austria 233 Switzerland 225 ATTENTION: please don't set any other ISDN country code than specified otherwise your ZyXEL ISDN product won't work correctly and then the behaviour for D-channel singalling would cause malfunction (especially if some country specific features will not be supported or implemented in the ISDN Central Switch firmware for the ISDN basic rate access in your country) ! * Japan Version ------------- 6. For Japanese ISDN, the Elite can detect the frame of V.110 57600 bps in multi-auto mode. 7. For Japanese ISDN, link layer is always active (layer 2 in state 7). * Internal Modem/FAX ------------------ 8. If you set the FAX to DRAM/PRINTER feature enable ( ex. "AT+FZF=1"), incoming analog calls will be routed to internal fax/modem ( "AT&L1") by default. 9. Internal modem is version 1.13a. -> please read seperate release notes. * Miscellaneous ------------- 10. Type 1 security function ("AT*G1"). 11. Keypad signalling function on the a/b-adaptor, for Sweden only. It's necessary to set the country code to Sweden (250). 12. For PPP/MP: S87.2=0, CHAP/PAP for authentication conversion. S87.2=1, PAP only for authentication conversion. 13. S79.7=0, respones "RELEASE COMPLETE" with cause "call rejected" while receiving an incoming call after issuing "ATH1". S79.7=1, respones "RELEASE COMPLETE" with cause "user busy" while receiving an incoming call after issuing "ATH1". 14. For USA version, now user can enter Directory Number: ATDNx=s, x=0,1, s=phonenumber. Known bugs of version 2.04: --------------------------- 1. V.110/38k4-8n1 compatibility problem with "CITAM" ISDN-TA. The German product "CITAM" uses another version of Siemens V.110 chip. 2. For "cFos channel bundle" (CCB, "AT&J3S100=1") connection, during file transfer, pick up the phone and make a call then drop the phone call. The B2 channel will be reactived, but it encounters many bad CRC and file transfer will stop. 3. In the ESCAPE state ("+++") of a V.110 connection, issuing "ATI2" will disconnect the connection, while "AT&V" will cause CTS low. 4. For U model of USA version, A/B adater offhook will generate garbage during V.110 connection. 5. after an AT+FCLASS=8 the ATZ does not reset to AT+FCLASS=0 suggested workarround: AT&FZ 6. dialing with a ";" character in the phone number sends an outgoing SETUP message without any CALLED PARTY NUMBER information element This happens with the LOTUS "ORGANIZER v2.0" application (dial suffix:";" - so this application dials "ATDTnumber;") 7. ATCS/ATCR (Call Suspend and Call Resume) does not work in all circumstances - needs further tests. 8. ATH1 ("call reject" or "user busy" singalization) does not work after an incoming RING. To prevent incoming calls the ATH1 command has to be sent BEFORE an incoming call. 9. ATB41 (SLIP to HDLC conversion): does not work if S124<>0 - the idle timout does not work, needs further tests. 10. ATV&K&N16DM.... (at least tested with 1TR6 firmware v2.03k) responses with numeric result code "4" on the followings ATD commands. 11. AT&NV&KDM..... (at least tested with 1TR6 f/w v2.03k) responses CONNECT but after this CONNECT message some garbage characters are received, which have definitvely not been sent by remote site. This happens to special analog modems only (eg: Creatix 2496) 12. AT&N14 - no analog connect possible if calling from f/w v2.03k to v2.03c. Needs further tests ... 13. E2864I does not report "BUSY" on some specific ISDN PABXs when the D-channel DISCONNECT message contains the location "private network serving local user". Instead of "BUSY" in this case the Elite reports "NO CARRIER" ----------------------------------------------------------------------------- July 2, 1996 Release Note on Elite 2864I Version 2.03 ======================================== Fixed the Bugs: --------------- 1. ATCG test may fail for U-interface model. 2. AT$ can't work after showing a few pages. (A bug of Version 2.02) 3. S119.4 should work only for ATB10 but not ATB18. 4. S41.6 (Force S0>=2) does not work. 5. S103 does not work. S103= Set number of RING to the a/b adapter 0 - The call sent to the a/b adapter will keep ringing until the call is answered or the calling side on-hook. n>0 - When the RING count has reached the value set (n), the a/b adapter analog call will be re-routed to internal fax/modem 6. *G4 function has some problems when using internal modem. 7. V.120 performance enhancement. 8. If the internal modem is set to &K0 (none error control), the loop-back test (AT&T8) will show garbage on the DTE in the beginning. 9. If the time difference between outgoing SETUP message and incoming SETUP ACKN is exactly 7 (or 17 or 27) milli seconds, then the a/b-adapter does not dedect DTMF dialtones - no CALLED PARTY information elements will be sent ! 10. Feature phone doesn't work (no dial tone after push button "0") since version 2.01. 11. When dialing for the a/b adapter from DTE using ATDBxxxx command, once the "In-Band-Info-Now-Available" message is received, the signal from the B-channel should be indicated in the internal speaker. 12. S56 (for the hook-flash time setting) has some problem. 13. Ever since dial from the DTE for the a/b adapter using the "ATDBxxx" command, put the handset on-hook will cause a "NO CARRIER" indication to DTE. This is deprecated by most users. 14. The internal modem cannot connect with V.FC modems in EC mode. For none error control mode, it will connect but the data transfered is incorrect. 15. When the a/b adapter is dialing out (overlap sending), if modem receives a PROGRESS message with "in-band-info-avail,", the a/b adapter will stop sending any number. 16. With version 2.02, one tenth of the 2864Is was crashed in 24 hours during alternative connections of modem and isdn call. 17. Elite 2864I does not send the "user busy" cause in a "RELEASE COMPLETE" message but in "RELEASE" message. 18. Elite 2864I send "STATUS" message with cause "message not compatible with call state" after receiving "FACILITY" message. 19. AT+FLID="...." isn't stored in NVRAM. 20. AT&D3 doesn't load profile #0. 21. While dialing to some toll-free numbers, the feature phone functions of the POTS port (a/b adapter) are not available and the call can not be disconnected at all. In this case, the network doesn't send "CONNECT" but only "PROGRESS" message. 22. AT&F does not reset FCLASS mode if it has been set to 8. 23. When the internal modem is in alerting state (sending RING indication to the DTE), if the DTE issues "ATZ" (or "dropping DTR" or "AT&F"), the modem will release the incoming call. 24. ATCRn where 128 > n > 3, will cause Elite to crash. 25. ATB04 does not imply ATCL125, ATB04 must be the same as ATB04CL125 (for German "T-Online Decoder" MODEM configuration). 26. ATB04 followed by AT&F does not set the 2864I to factory default (X.75). 27. ATB20 does not imply ATCL256, ATB20 must be the same as ATB20CL256 28. The second line of the AT&V6 display was "Called ID (AT&ZOA=)...". It should be "Called ID (AT&ZOB=)..." 29. ATI3 "Cause:" -> verbose cause result string is missing ! This has once worked in the previous version v2.01. 30. AT&ZOx= can't be set to "UNASSIGNED" because of the inconsistancy: AT&ZIn= (<cr> = empty string) is valid AT&ZOx= (<cr> = empty string) is invalid (ERROR) 31. The factory default value of S56 should be 50. It was 0 after issuing AT&F. 32. If the Elite is set to ATH1 then any data call should be rejected with the RELEASE COMPLETE message with cause value "call rejected" (it was "user busy") 33. When issuing "ATH" in Escape state (after "+++") should get "OK". 34. If there is an MSN assigned for fax/modem ( FCLASS = Z ) and an incoming call matches with this MSN and while the DTR is off, then the fax will not be received ( "user busy" ). 35. Issuing "ats0=250" will cause the modem to pickup in 1 ring. 36. If the DTR goes from ON to OFF during the alerting state, the ring count of of S1 should be frozen until the DTR goes ON again. 37. The problem of parallel printing: issue "at+fclasss=z", "ats0=5" and DTR is off, then a fax call come in. This will cause the "RING" and "TO:xxxxxx" messages sent to the printer. 39. If the internal modem connects 300 bps with the "Austrian Personal Pager System II" the response is "CONNECT CONNECT". 40. Connection problem (outgoing call) with Telekom Austria's "MidiStar" and Siemens Hicom PBX. Now, 2864I doesnt't send STATUS message after receiving CONNECT message with IE 00/4C. (which is the activated ISDN supplementary service called "COLP") 41. Issuing ATH may get two "OK" responses in idle state. 42. DTR off will hang up the phone call of the analog port, which is placed via the ATDBxxxx command. 43. For Japanese version, DTMF tone can not be detected. 44. Unable to transfer file using X.75+V42bis connection with length = 252. 45. Issuing "S23?" command causes 2864I to crash. 46. Hardware reset doesn't work. 47. After remote site hanging up during a phone call placed with ATDBxxxx, issue ATO may get connect message. 48. Issuing AT&T8 (or AT&T1) then dropping this connection (press any key) during handshaking causes LNK LED to turn off and the commands AT&T9 and AT&T10 will never work again. 49. Issuing "A/" after AT*Hn and a wrong password will get some garbage responses. 50. The AT&M1 should be responsed with "ERROR" because this feature is not yet implemented. 51. Issuing AT+FCLASS=ZZ0 causes 2864I to crash. 52. Improved the reliability problem that 2864I can not run for 24 hours. 53. Issuing ATH3 to drop a/b adapter connection may get "OK" and "NO CARRIER" it should only be responsed with "OK". 54. After some connections, issue ATA to accept an incoming call will get an "ERROR" message. 55. When layer 1 is deactivated (cable unpluged), dial out by issuing ATDxxxxxx may get no response. It should be responsed with "NO CARRIER". 56. Set &J3 in call site and &J0 in answer site to make a connection then issue "ATH" to drop this call will get "BUSY". It should be responsed with "NO CARRIER". 57. If the 2864I is configured as S0=1 (Auto answer) and &D0 (Ignore DTR signal, assume DTR is always ON) and the RS232 cable is removed, an ISDN connection session followed by a modem call will cause the 2864I to reset due to a Run-Time-Error. 58. For Japanese version, the ringing signal of the Analog port is not recognized by the YUPITREU YP-A72 answering machine. 59. *G4 function error for internal modem 60. The S89.4 doesn't work properly. S89.4 = 0, Second incoming voice call will be routed to the a/b adapter if &L1 is set and modem is running.(by default) = 1, Second incoming voice will be rejected if &L1 is set. 61. CD LED lights up too early before B-channel link is fully established. 62. The "AT&Zn" command can not have ',' in the phone number string. 63. The 2864I can't auto-login into the Germa "T-Online Service" system. (Due to a limitation of the COM port solution of the "T-Online Decoder" software, the packet size should be as small as 125 octets (using "ATB04CL125"), otherwise it's unable to browse the Internet via T-Online) 64. During the a/b adapter dialing out (overlap-sending), if the modem receives a PROGRESS message with "In-Band-Info-Now-Available" indication, the a/b adapter will stop sending any number. New Implemented: ---------------- 1. Added ATDSn+Sm and ATDnnnnn+mmmmm functions for placing a bundle call. These commands are useful if the called party resides in the America where seperate phone numbers must be used to connect the two B channels of a Basic Rate ISDN line. When these commands are used, the modem will assume a bundle call is invoked regardless the setting of "&Jn". 2. For some none end-to-end ISDN connections, e.g. using the a/b adapter to dial to a POTS telephone, there will be no ring-back tone since the 2864I doesn't receive any ALERTING message from the network. The modem now generates artificial ring-back tone once it receives the PROGRESS INDICATOR that indicates not end-to-end ISDN. One defect of this implemention is that the remote site may eventually found to be busy thus the ring-back tone may be followed by busy tone. But it's better than nothing can be heard. 3. MultiAuto function for the protocol identification of the inbound calls. If no MSN has been set (using the "&ZIn=xxx" command), the modem will automatically decide the protocol of the incoming call. For analog calls, we still rely on the setting of "&Ln" to determine whether it's the modem or the a/b adapter to be routed. The "&ZIn=xxx" has modified as follows: &ZI0=s Assign the phone number for X.75 &ZI1=s Assign the phone number for V.110 &ZI2=s Assign the phone number for V.120 &ZI3=s Assign the phone number for PPP async to sync HDLC &ZI4=s Assign the phone number for ISDN data (Multi-Auto answering, auto detect the protocols) &ZI5=s Assign the phone number for PPP async to sync HDLC &ZI6=s Assign the phone number for internal fax/modem &ZI7=s Assign the phone number for the a/b adapter If one MSN is multiple assigned to more than one protocols, the MultiAuto function will also help to resolve the ambiguity. 4. More ragid layer 1 driver that has passed the Telecom Italia's Comformance Test. 5. MP/PPP new function, please see PPP_MP.RTF (WORD file) or PPP_MP.TXT (ASCII file) 6. Internal modem is version 1.12d. -> please read seperat release notes. 7. For Japanese ISDN, the Elite 2864I now supports V.110 57600 bps which is a proprietary protocol of NEC. 8. For North America ISDN, the Elite 2864I now supports DOVBS (Data Over Voice Bearer Service). To place an ISDN data call using the Voice Bearer Service, please set S83.7=1. Note: It is recommended that the desired settings of the Elite 2864I be stored in one of the user profiles (using the "&Wn" command) and the profile be set as the power-on default settings (using the "Zn" command). Although not very often, the modem may be reset due to unexpected run-time-error after long term operation. Once this happens, the desired settings will be resumed and the modem is ready to serve instantly. 9. In version 2.01, we implemented S119.4 for V.110 maximun user rate. This was incorrect because S119.4 has been used to select result code type since version 1.11. Thus a new flag must be devised to represent one of the two selectors. We apologize for the mistake. The final definitions are as follows: S119.4 = 0, V.110 maximum user rate is 19.2kbps = 1, V.110 maximum user rate is 38.4kbps (by default) S87.4 = 0, result code 46 for X7 is 'CONNECT 112K/... ' result code 47 for X7 is 'CONNECT 128K/... ' = 1, result code 46 for X7 is 'CONNECT 112000/... ' result code 47 for X7 is 'CONNECT 128000/... ' 10. If DES is enabled, bundle call won't be established. That means DES is of higher priority than the channel bundling. 11. The country code of the internal modem will stick to 255. By doing so, we made a detour to the problem that modem doesn't work after upgrading from 2864 to 2864I in case the original country code is other than 255. 12. Plug and Play function for Microsoft Windows95 -> therefor you need the new modem description INF file (July 1996) 13. Added guarding timer for 'AT' autobaud detection. Known bugs of version 2.03: --------------------------- 1. S38.0=1 & S44.3=1 don't work 2. V.110/38k4-8n1 compatibility problem with "CITAM" ISDN-TA. The German product "CITAM" uses another version of Siemens V.110 chip. 3. Issue ATCM2 ( CAPI 1.1a driver ) or ATCM3, any incoming call and a/b adapter hook state change causes the Elite's function abnormal. 4. Voice connection fails to send <dle><etx> at the end of the voice data stream. ----------------------------------------------------------------------------- May 8, 1996 Release Note on Elite 2864I Version 2.02 ---------------------------------------- this firmware has not been officially released as upgrade to endusers but it has been shipped with new modems since mid of May 1996 ! The release notes are now merged to the release notes for version v2.03 listed above. ----------------------------------------------------------------------------- March 14, 1996 Release Note on Elite 2864I Version 2.01 (aka "CeBIT'96 Release") ----------------------------------------------------------------- (For DSS1 and 1TR6 only) Fixed the Bugs: -------------- 1. Bad PPP performance: The FCS problem has been fixed and the throughput is now in normal condition. 2. Self-test AT&T8 hang up by D/V key or DTR drop will cause B1 LED ON. 3. Two Elite 2864I on the same S-bus (point to multi-point) sometimes can not answer the call due to the TEI assignment conflict. 4. TXD LED and RXD LED don't work in PPP mode. 5. After printing the receiving fax, the a/b adaptor doesn't work. 6. AT+FAA=0 or 1 will cause the "ERROR" response. 7. The 2864I ignores the incoming call while MSN matched but the specified protocol is in use. Now it will response RELEASE message with cause "BUSY" to network. 8. ATS18=1 causes the auto-bauding malfunctioning. 9. If remote site is busy, EPA information displays "No Carrier". It should be "BUSY". 10. The problem of V.22bis/None that will hang the modem. 11. Improve the performance of the internal modem. (Now the internal modem is version 1.12 ---> please see also the release notes for the analog modem also: the filename is "E2864_RN.112"). 12. ATQ2 does not work correctly. 13. If in-band signalling is unavailable, occasionally there is no ringback tone while dialing to PSTN because no ALERTING message will be received. Now the 2864I will monitor the CALL PROCEEDING message and generate the ringback tone as indicated. 14. V.110 19200bps does't work. 15. Improve Japanese redial restriction function. 16. ATI4 and ATI5 report strange strings. The responses should be "ERROR". 17. Bundling problem for USA. 18. Improving U-module start-up timing. 19. Sporadically, 2864I indicates "RESET" after connect message with X.75 protocol, and hangs up. 20. S7 must be ignored when dialing with the command "ATDB...." for the a/b adapter. 21. For 3.1k audio "BEARER CAP.", there is no (shall have) "PROGRESS IND." #3 (= 'origination is non-ISDN ). 22. T310 must be stopped after "CALL PROC." message with the "PROGRESS IND." #1 (= 'call is not end-to-end ISDN'). 23. Two 2864Is on the same S/T interface cannot dial to each other. 24. "ati2" doesn't work in the escape mode of an ISDN call. It will also cause a later on "ath" or "ato" malfunctioning. 25. The problem of hardware reset for U-interface model. 26. Pressing the Data/Voice button when there is no connection will give "AT" and "OK". A user should be able to press the D/V button to go off-hook and pick the call up (quick dial). 27. When "at*t" is issued and there is no caller-id available the modem indicates "LAST FM: NO Sending", this has been changed to "Last FM: NO Information send from switch". 28. The security problem while setting either *G4 or *G5. 29. ATZ1 - Z4 don't work. 30. The problem with Octopus and HICOM ISDN-PBX. Elite ID can't dial out over these PBX. 31. The problem that Elite 2864I response RELEASE message with "incompatible destination" If an incoming SETUP message with "unrestricted digital information" and "A-law" together. 32. The problem with display charging information (ATCH?) for 1TR6. 33. The performance of X.75+V.42bis deteriorates significantly while transfering very compressible files. 34. Improved auto-bauding function. 35. Fax receiving didn't work in version 2.00. Implemented: ------------ 1. Inband signalling available function for the a/b adapter. Also, when dialing with the a/b adapter, the B-channel won't be released so long as the phone is in OFF-HOOK state. User can hear the busy tone ( remote hang up ) provided in-band by the network. 2. S56 (in 10 ms unit), hook flash valid time for the a/b adapter. Please have some tolerance for the flash time interval, e.g. if your the flash specification of your telephone set is 70 ms, you should set S56 to be 9 (90 ms) for 20 ms tolerance. 3. S118.0=1, Disable dial-in call ( dial out only ). 4. Call back function for ISDN call: AT*VC, View call-back table. AT*HCn, Modify call back phone number (AT*HCn=xxx, n=0-4). AT*HS, Modify supervisory password (Default: 'ZyXEL'). AT*GCn, Call-back function selection. n=0, disable. n=1, enable. S119.0=0, Disable call-back function (see AT*GC). S119.0=1, Enable call-back function. 5. Password function for modem call, there are 40 storing passwords. AT*V, View password table. AT*HS, Modify supervisory password (Default: 'ZyXEL'). AT*Hn, Modify user password table at location n (n = 0-39). 6. AT*G3, *G4, *G5 for both ISDN call and modem call. 7. Connect/disconnect problem for some PPP Servers. S124 (in second unit) will be used for the idle time gauge. If the idle time exceeds this time, a dummy PPP packet will be sent to keep the Server from disconnecting the line. ATS124=0 will disable this function. 8. ACCM function for PPP. The 2864I will monitor the ACCM option selected during the LCP negotiation and follow the result. 9. S119.1 = 1 will enable the point-to-point signaling (DDI) function. S119.2 = 1 will enable the point-to-multipoint signaling (DDI) function. 10. Improved MSN function: In the case of any MSN (AT&Zix = s) is set, S119.3=0, and MSN mismatched, 2864I will ignore the imcomming call. In the case of any MSN is set, S119.3=1, and MSN mismatched, 2864I will connect with default protocol setting. If no MSN has been assigned, S119.3 will be ignored and a call will be received using the default protocol. 11. S120,S121, Accumulated charging unit for B1 channel. S122,S123, Accumulated charging unit for B2 channel. 12. S119.4 = 0, V.110 user rate = 19200 bps if DTE speed greater 19200 bps. S119.4 = 1, V.110 user rate = 38400 bps if DTE speed greater 38400 bps. 13. S119.5 = 0, enable normal MSN function, using &ZIn=. S119.5 = 1, treat the number assigned by &ZIn=xx.. as subaddress and matches with the called party subaddress for inbound call routing. 14. S89.3 = 0, Keep connection whether there is DES or not. S89.3 = 1. Disconnect the call if DES link cannot be established. 15. The voice mode function works now. 16. DES link status indication on the B1/B2 LED. Single blinking for single-DES and triple blinking for triple-DES. Known bugs of version 2.01 - ("very sorry, very sorry - it's not perfect yet") The following items were recognized on March 13th, 1996: ----------------------------------------------------------------------------- 1. After F/W upgrade (using ATUPX) the AT&W command doesn't work. 2. Feature phone doesn't work (no dial tone after push button "0"). 3. V.120 channel bundling may get stuck after 20 minutes of file transfering. 4. ATH in command state will have double "OK" responses. 5. Off hook the a/b adapter and issue AT&T1 or AT&T8 will cause the modem to crash. 6. S56 (for the hook-flash time setting) does have some problem. 7. DES cannot be invoked if the called 2864I has been configured as &j3. 8. When dialing for the a/b adapter from DTE using ATDBxxxx command, once the "Inband-Info-Now-Available" message is received, the signal from the B-channel should be indicated in the internal speaker. 9. If the internal modem is set to &k0 (none error control), the loop-back test (AT&T8) will show garbage on the DTE. 10. Push the D/V button in the command state will cause the modem to generate "AT" and "OK" responses to the DTE. This is incorrect. 11. During the a/b adapter dialing out (overlap-sending), if the modem receives a PROGRESS message with "In-Band-Info-Now-Available" indication, the a/b adapter will stop sending any number. The following items were recognized on March 14th, 1996: 12. Windows95 Plug&Play Feature: the Elite ISDN will be recognized as "E2864 V 1.12" - should be "E2864I V 2.01" ----------------------------------------------------------------------------- December 4,1995 Release Note on Elite 2864I Version 2.00 We have finished the simplified DTE channel modification, please refer to "QUICKREF.TXT" file for testing (also see on-line help or manual file "E2864I20.MNU" ).

New result code, please refer to file RSTCODE.DOC. ----------------------------------------------------------------------------- September 21,1995 Release Note on Elite 2864I Version 1.09 1. Improve the performance of the internal modem. We reduce the receiving level to protect saturation of input signal. 2. The transmission level of internal modem is fixed to -15dBm ( S17b1-4 ). User can not change this value by AT*Pn. The reason is also for the performance of the internal modem. ----------------------------------------------------------------------------- September 12,1995 September 12,1995 Release Note on Elite 2864I Version 1.08 Fixed the Bugs: 1. The problem that 2864I can not dial out with the switch of Siemens NTBA and ALCATEL. 2. The problem that sometimes user get two "NO Carrier" indications. 3. AT&Cn, S42.7 actions for CD led in DTE channel 0. 4. The bug of numbering plan "YnNn" while dialing out. 5. The problem of EAZ for 1TR6. Now, EAZ number will be send in "SETUP" message using AT&ZO command to setup. 6. The bug that incoming modem call will be accepted by a/b adapter when internal modem is busy. Implemented: 1. ATB04 for Datex-J connection. 2. ATH1 command for disable receiving incoming call. 3. ATS119.5 = 1 will disable channel bundling in answer mode. 4.

Modified SPID structure for USA. ----------------------------------------------------------------------------- August 22,1995 Release Note on Elite 2864I Version 1.07 Fixed the Bugs: 1. ATZ in any DTE-channel disconnects voice call on active a/b adapter, now it can not reset or hang up an 2864I while the a/b connector is used. 2. AT&V doesn't work after ATZ command. 3. DTR off does not disconnect a call. 4. In DTE channel 3, AT&WC3 may change the active channel to channel 0, and ATZ03 may change to channel 2. 5. Only get the connection message "C" if the setting is AT&J1&X6 or AT&J1&X7. 6. DTE channel 3 outgoing setup will take CGPN/CGPS from active DTE channel. 7. PPP's incorrect FCS of large incoming packet ( need further test ). 8. User-to-User information ( need further test ). 9. LLC information error of X.75/T.70NL ( maybe the solution of problem that can not access Datex-J, but need further test ). 10. 40 seconds timeout "temporality failure" on long distance calls with "CALL PROCEEDING" message for DSS1 ( need further test ). 11. Fax receiving problem: 2864I does not send the "<cr><lf>CONNECT FAX<cr><lf><cr><lf>ZyXEL<cr><lf>" as U-1496. 12. If an incoming modem call fails during handshaking, the 2864I will crash. Implemented: 1. S7 has been implemented as a per-channel register. 2. After AT&F, Active channel will change to DTE channel 0 ( need further discussion ). ----------------------------------------------------------------------------- August 15,1995 Release Note on Elite 2864I Version 1.06 Fixed the Bugs: 1. AT&T8 doesn't work properly with X.75. 2. 2864I crashes after power-on, if command ATDL is issued in the beginning. 3. AT&W only works on DTE channel 0. 4. Busy tone problem of the a/b adapter for a long distance call ( need further test). 5. No connection message if the setting is AT&J1X6 or AT&J1X7. 6. Get "No Carrier" response after ATH command even when the 2864I is idle. 7. Lock-up problem with ATDSn, if n >= 40. 8. No response message after ATO command ( Now you get the connect message ). 9. "AT" detection problem with script file. 10. The bugs of AT&Cn, AT&Dn 11. When set to numeric code it reports the correct code but in three digits ("000","001" ..). 12. Disconnecting the modem during handshaking stage will make the 2864I crash ( in fact, 2864I will reset and display the crash code ) 13. the problem of TXD led during file transfer. 14. Geting "Error" response after ATDSn if the optional digits "T", "M" or "I" are included in dialing number n ( stored by ATZOn = Txxxxx ). 15.

Implement : ATDI ( ISDN call ) and ATDM ( Modem call). 14. Implement : ATDL and ATDTL. ----------------------------------------------------------------------------- July 3,1995 Release Note on Elite 2864I Version 1.02 1. Normalize the indicated message of incoming call: 1.1 No Calling party number : do not show "FM:" 1.2 No Called party number : show "Global Call" 2. Fixed the bug of pulse dialing. 3. "BUSY" and "No Answer" indications have been inplemented. 4. the command ATCN and ATCI have been implemented. 5. Ring indication has normalized, S7 has been inplemented. 6. These two bytes <cr><lf> of AT&V,AT$,ATC$ has been swapped. 7. Fixed the bug that DTR off can not hangup the call. 8. The dictionary size of V42bis has dynamically changed according to receiving XID parameter. ----------------------------------------------------------------------------- June 24,1995 Release Note on Elite 2864I Version 1.01 1. For 1TR6, the outgoing service indicator and default value is corrected, so internal fax/modem now works. 2. MDM LED is more reliable. 3. For North America ISDN, LNK LED works correctly during SPID management procedure. We also fixed some bugs of signalling. 4. Fixed the bugs of ATZ. 5. After you download the Version 1.00 or 1.01, please first check the MSN of each service by AT&ZI?. If the number is not correct or doesn't smell very healthy, you should enter the correct number (AT&ZIn=xxxxxx) or empty it (AT&ZIn=) and use AT&W to put the new assignments into the NVRAM. This is very important for answering calls. The corresponding memory space of the NVRAM is not properly initiated by the old versions of F/W. ----------------------------------------------------------------------------- June 21,1995 Release Note on Elite 2864I Version 1.00 1. The a/b adapter (analog telephone port) can accept both pulse dial as well as DTMF tone dial. The only exception is that when the built-in fax/modem is running, only pulse dial is possible. 2. The metering pulse function of the a/b adapter has been implemented for 1TR6 (German national ISDN). Use ATS102.6=1 to enable the metering pulse function; ATS102.6=0 to disable the metering pulse function. 3. The outgoing Low-Layer-Compatibility information element can be turned on or off as follows: ATS115.4=0 Disable outgoing Low-Layer-Compatibility (default) ATS115.4=1 Enable outgoing Low-Layer-Compatibility 4. The own number assignment command has been modified such that only one number-subaddress pair can be assigned to each DTE channel. The old command was AT&ZOn=s , n=0,1 the new one is AT&ZO=s 5. For DSS1 and North America ISDN, the Multiple Subscriber Number (MSN) supplementary service provides the possibility for assigning multiple ISDN numbers to a single ISDN BRI line, that allows a calling user to select, via the public network, one or multiple distinct terminals out of multiple choices. Since the Elite 2864I is a highly integrated multi-function ISDN modem, it can be imagined as a black box that contains multiple distinct terminals. Each of these "internal terminals" can be assigned one ISDN number using the following command: AT&ZIn=s n=0-7 &ZI0 assign the MSN for X.75; &ZI1 assign the MSN for V.110; &ZI2 assign the MSN for V.120; &ZI3 assign the MSN for PPP async to sync HDLC; &ZI4 assign the MSN for SLIP to sync HDLC; &ZI6 assign the MSN for internal fax/modem; &ZI7 assign the MSN for the a/b adapter. AT&ZI? can be used to display the MSN numbers assigned by the AT&ZIn=s commands. The factory default for these numbers are UNASSIGNED. If an incoming SETUP message is offered with addressing information (i.e. the appropriate part of the called party number), this address will be compared with the MSN numbers assigned by the the AT&ZIn=s commands. The call will be accepted using the specific protocol if the assigned number of this protocol matches with the received called party number. Note : Two phone number strings are said to be matched if their least significant "n" digit(s) are identical, where "n" is the number of digit of the shorter string. Usually one digit is enough to distinguish the various protocols. 6. Called-Party-Subaddress information of the incoming SETUP message is not used by the Elite 2864I to select the protocols or services. The Elite 2864I just indicates the subaddress (if any) to the DTE. 7. Each phone number of the destination BRI line can be called only once at a time for the Northern Telecom ISDN. In order to use two B channels for channel bundling, we must place two calls with different phone numbers. Thus we implemented the command ATDnumber_1+number_2 where number_1 and number_2 are two phone numbers of the same ISDN BRI line. 8. The reset problem of the ATZ command has been fixed. 9. In case the ATC$ command (to view captured message of the EPA) has no effect, please try to issue ATH first and then ATC$. We are working on this bug. 10.The command ATI2 has been implemented, it will indicate the disconnect reason of the last call. 11.For the Elite 2864 (the V.34 modem), there are four user profiles. But for the Elite 2864I (the ISDN modem), because there are four DTE channels in the Elite 2864I, each has its own configuration, the same NVRAM space can only afford ONE user profile for each DTE channel. Please use the on-line-help commands AT&$ and AT$ to see the definitions of the commands that are pertinent to the user profile: AT&Vn, AT&W, AT&F, ATZn 12.The V.120 data compression (V.42bis) of the Elite 2864I now follows the "Annex C to Rec. V.120", which is a proposal from IBM that defines the procedures of request and parameter negotiation of V.42bis over V.120 by means of exchanging XID frames. 13.The lattest version of the Elite 2864I user's manual is Rev. 1.1. 14.The problem of class 2 fax has been fixed. Please try it under DTE channel 0 (AT&ZO0, for internal fax/modem). ----------------------------------------------------------------------------- May 30,1995 Release Note on Elite 2864I Version 0.03 1. Fixed the bugs of ATZ and AT&Ln. 2. Dual TEI function has been implemented for the Northern Telecom ISDN DMS-100 so that two B channels can be used simultaneously. 3. Fixed the bug of the internal fax/modem of American version where an incoming call can not be answered. 4. The output power of the the a/b adapter was too high in the previous versions. We changed the output power to the correct level. 5. A new V.34 firmware with better performance has been included in this version. 6. For north America ISDN, the LNK LED will light up after power-on when the SPID registration is finished and the link connection is established between the ISDN modem and the Central Office. ----------------------------------------------------------------------------- May 22,1995 Release Note on Elite 2864I Version 0.02 1. The internal fax/modem has been integrated into the Elite 2864I's firmware. This includes G3 fax, V.32bis, ZyXEL 19200 as well as V.34 modem. Please test these functions in the DTE channel 0 (AT&O0). We are porting the voice mode on the Elite 2864I. Don't issue any voice command now ! 2. The SPID (for North America ISDN) assigned via the AT command ATSPIDn=xxxx is stored in the NVRAM. When power-on the Elite 2864I, it will automatically handshake with the switch for TEI assignment. 3. The AT&Dn and AT&Sn commands have been implemented. 4. The AT&Vn command has been revised. Please use AT&$ command to view the new definition of this command. 5. Remove the ISDN line before using AT&T1 (ISDN loopback test) or AT&T8 (ISDN loopback with self-test). We found that during these tests there will be B-channel data leakage to the S/T interface. We are trying to fix this problem. 6. We failed to include the dual TEI function in this version. Please wait for the next version (0.03). ----------------------------------------------------------------------------- May 9,1995 Release Note on Elite 2864I Version 0.01 1. Please press the D/V button and turn on the Elite 2864I to do a hardware reset on the modem and have the modem load in the factory default settings. 2. Please refer to the 2864I series ISDN modem user's manual for explanation of the power on self-test. 3. Use ATI1 to check the ISDN modem's firmware version. Firmware version 0.xx is used for ß-test. The formal commercial version will start from version 1.00. ATI1 will also show the version of the internal fax/modem, which has the same definition (and the same features) as the firmware version of the Elite 2864 V.34 modem. For this ß-version (Ver 0.01) the internal fax/modem is not included. It will be added into the Elite 2864I in the next version (Ver 0.02). 4. If the D-channel signaling protocol installed in your sample(s) does not fit your ISDN switch you can upload the proper firmware into your samples' flash EPROM. There are three files for this version: E2864IE.001 .... European ISDN (DSS1) E2864IG.001 .... German ISDN (1TR6) E2864IA.001 .... North America ISDN (NI-1,AT&T 5ESS, and NT DMS-100) Please refer to Chapter 3 of the user's manual for procedures of uploading the firmware. 5. There are four on-line help commands that you are recommended to try first: AT$, AT&$, AT*$, and ATS$ 6. The Embedded Protocol Analyzer (EPA) can be a very powerful tool for ß-testers to record and report the test result. Please refer to Chapter 12 of the user's manual. 7. We have just implemented the feature-phone functions to the a/b adaptor. Please check if they work well. 8. The data encryption function is also new in this version. Please refer to Chapter 14 of the user's manual for detailed information. You can send short plain-text packets and use the EPA to capture the B-channel's cipher-text to see the effect of the encryption. Both manually entered key or automatic session key can be used. 9. The dual TEI capability required by the NT DMS-100 will be added in the next version (Ver 0.02). Also we have not stored the SPID into the NVRAM so you may have to key-in the SPID every time when you turn on the Elite 2864I. 10.The channel bundling protocol now implemented is X.75 MLP (TELES compatible). We are working on the cFOS Channel Bundling and hoping that we can include it in version 0.03. 11.For the B-channle protocols, in addition to the V.120, V.110, and X.75, we have added the PPP async-to-sync HDLC conversion as well as the SLIP to sync HDLC conversion. These protocols are useful for the LAN/Internet applications. Please refer to Chapter 8 of the user's manual. 12.If you are running at 460.8K bps DTE speed, please make sure you are using the 486DX 66MHz(or faster) machine and the Procom-Plus(or a more efficient one) communication program. The Smartdrv function must be enabled. A simple way to isolate the fault if you have too many CRC error indications during file transfer is to use the V.42bis. Any error occurred below the link layer will likely cause the ISDN modem to blow out. If the ISDN modem is still alive and there are CRC errors, the DTE interface or the Computer may have some speed problem. 13.AT&T1 (ISDN loopback test) and AT&T8 (ISDN loopback with self-test) can be used for quick evaluation of the B-channel protocols as well as the hardware. Only V.110, V.120, and X.75 can be tested. Data encryption, V.42bis, and/or channel bundling can be enabled in these tests whenever applicable. -----------------------------------------------------------------------------
