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.
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 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.
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).
June 24,1995
Release Note on Elite 2864I Version 1.01
1. For 1TR6, the outgoing service indicator and default value is correct,
so internal modem connection work.
2. MDM LED is correctly handled.
3. For North America ISDN, LNK LED is correctly handled during SPID
management procedure. Fix some bugs of connection.
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 is some
garbage, it is necessary to enter correct number (AT&ZIn=xxxxxx) or
empty it (AT&ZIn=). This issue is very important for the first time to
accept incoming call.
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.
