               Release Note on Elite 2864I Version 2.03
               ========================================



Important Notes:
================
Because new implemented features and some changed behaviours concerning
the auto-dedection of the various B-channel protocols for incoming calls
will cause some incompatibility to privous firmware releases:

 1. V.42bis data compression on ISDN B-channel protocols X.75 and V.120:
 -----------------------------------------------------------------------
    If any user tries to connect with the ZyXEL Elite 2864I ISDN having
    the firmware before v2.03 and &K44 (V.42bis ISDN data compression).
    is ENABLED (!) then the answering Elite 2864I ISDN with f/w v2.03
    will fail to accept this V.42bis because of the new modfied V.42bis
    handshaking sequence although it has already entered the CONNECT state
    (and the calling site will be charged by his PTT for the active
    connection for only one second !)
    The same situation occures when calling to any ISDN card which uses
    the Teles.CAPI for OS/2 Rel. v3.10. (This is a bug in Teles.CAPI f. OS/2,
    it does not exist with Teles.CAPI for DOS or WINDOWS !)
    As solution to this behaviour we recommend:
    a)  either to disable the V.42bis ISDN compression with the command
        AT&K3 when using the ZyXEL Elite 2864I ISDN firmware before v2.00
        AT&K00 when using the ZyXEL Elite 2864I ISDN firmware v2.00 to v2.02
        in the calling (originating) Elite 2864I
    b)  or that customers having "old" firmware should upgrade to the
        latest new firmware v2.03 !


 2. offline FAX to DRAM/PRINTER receiving:
 ------------------------------------------
    If you didn't have specified any MSN number for the internal fax/modem
    device (using the command AT&ZI6=.....) then the FAX to DRAM/PRINTER
    feature won't work because then incoming analog calls will be routed
    to the a/b-adapter by default. (This will be changed in next firmware
    v2.04!)
    As solution to this behaviour we recommend:
    a)  either set a MSN number for Fax/Modem part with AT&ZI6=.....
    b)  or set the AT&L1 so that incoming calls (also if your ISDN BRA
        doesn't have any MSN number assigned to, ie: the "Global Call")
        will be routed to the internal fax/modem device.
        for example:
        AT&F
        AT+FCLASS=Z
        AT+FLID="my fax number"
        AT+FZF=3
        AT&L1&D3&W0Z



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.

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.

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.

                                                            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).

                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.

                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 -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 -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
   -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.
