Reverse Telnet not working on ACS 5350

    We seem to be having a problem reverse telnetting into our digital
    modems on
    an ACS 5350. They are setup on lines 1/00 through 1/59, configured
    with the
    following:

    line 1/00 1/59
    exec-timeout 1 0
    no flush-at-activation
    modem InOut
    modem autoconfigure type cisco
    transport input all
    escape-character NONE
    autoselect ppp
    !

    show line reveals the following....
    Tty Typ Tx/Rx A Modem Roty AccO AccI Uses Noise
    Overruns Int
    0 CTY - - - - - 0 0 0/0

    I 1/02 Digital modem - inout - - - 2 0
    0/0 -

    etc. until 1/59

    Line(s) not in async mode -or- with no hardware support:
    14-215

    Whenever we try to telnet to port 2001 (or any other port in the
    2001-2059 range), we get a "Connection refused" error.
    Is there anything else we should be looking at in the config to enable
    reverse telnet?

  2. Your lines 1/0 thru 1/59 do NOT map to
    lines 1 thru 59, so ports 2001 thru 2059 won't
    work.

    To find out what they map to, use "show controller async 1/0"
    (etc.)

    Thanks! We had already talked to Cisco and had gotten the reverse
    telnet working on port 7001 by adding "rotary 1" to the config, but I
    tried out the show controller async 1/0 command, and found that 1/0 -
    1/59 are mapped to TTY 216 to 275. Telnetting to ports 2216 - 2275
    seems to work beautifully.

    Thanks again!
