Cisco ISDN BRI S/T and Zyxel omni.net LCD+M

Discussion in 'Cisco' started by Mathias Gummert, Feb 17, 2005.

  1. I´m trying to connect two Ciscos via ISDN.

    The 2620 comes with a NM-BRI 4B-S/T and the 1721 is connected to a
    Zyxel omni.net LCD+M through a WIC-2A/S (I cannot use a B-S/T here,
    for I only have just one ISDN line through which also analog and GSM
    calls come in).

    Obviously there´s a problem within LCP after the routers connected. On
    both sides there are LCP frames going in and out (which is shown by
    the "debug ppp negotiation" output, see below), but the routers fail
    to negotiate - no matter which one is dialing and which one is
    receiving.

    It´s not a matter of usernames or passwords (two B-S/T Modules connect
    properly). I played with "ppp authentication callin, callout" with no
    result.

    I tried several different settings on the Zyxel (PPP, X.75, V.110,...)
    with no result.

    I tried the Zyxel´s different DTE speeds with and without locking it
    and no results.

    The Zyxel works fine with incoming analog, ISDN and GSM RAS calls. The
    problem is only with the Cisco´s B-S/T.

    Has anybody had this before and knows the solution?

    Any hint is welcome

    Here is the "debug ppp neg" - output:

  2. The connection with two Zyxel omni.nets is working fine. The problem
    is only when the Cisco B-S/T comes into the game.
