                Release Note on Omni TA128, Version 2.02c
               =========================================
                     for alpha-test group only !


Fixed Bugs:
----------
 1. Issue 'AT&D1' to dial default number function while the stored number is
    Axxx or Bxxx, then TA may not dial out while second DTR is off.
 2. While one B channel connect in data ( data call ) and another B channel
    connect in voice ( phone call ), dropping the phone call may cause the
    data call to disconnect sometimes.
 3. The setting of DTE port 2 should load factory default value. The default
    outgoing protocol is PPP.
 4. For 1TR6 version, the value of item 'Cause' while issuing 'ATI3' is not
    correct sometimes.
 5. V.110/38k4-8n1 compatibility problem with "CITAM" ISDN-TA. The German
    product "CITAM" uses another version of Siemens V.110 chip. About the
    setting of "CITAM": XX-bit should be set to "IGNORE" because this setting
    is normal V.110 configuration; "INBAND REMOTE SUPERVISOR" should be set
    to "OFF" because Omni TA128 does not yet have implemented the IPE
    function of V.110.
