                  =====================================

========================================================
        FILENAME          SWITCH TYPE
        "OLME100.BIN" ---- DSS1


2.New implemented features
==========================
  2.1   The omni.net LCD+M contents a built-in V.90 modem that can
        communicate with other analog modems through an ISDN line. The
        fax/modem can only support FAX CLASS 1 commands, that is, users can
        send and receive fax by applying popular compatible fax packages such
        as WinFax or Microsoft Fax but can not work under ZyXEL's ZFAX
        because ZFAX uses ZyXEL proprietary FAX CLASS 6.

  2.2   The internal fax/modem is using the same circuit of POTS port phone2,
        that is, when POTS port phone2 is in use, you can not dial out/in a
        modem call. On the other side, when internal fax/modem is in use,
        if you pick up phone2, you will hear the noise of modem carrier or
        handshaking.

  2.3   AT command set for modem or fax call:
    (1) ATDMs:Dial s(number and options) that follows for the internal
        fax/modem
