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.

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).
