    Can anyone tell me how I can detect when a router has gone to ISDN back-up
    (from a leased line)?
    Failing to spot this can potentially cost a customer a lot of extra fees.

    show isdn status should let you know if there's any call placed at
    layer 3, additionally you can the status of the channels with the show
    interface command.

  3. Hi Steve,

    You'll need some sort of NMS or syslog software. If you have a syslog
    server setup, you can have your router send syslog messages and then
    write a short script to parse the %ISDN-6-XXXX and %LINK-3-UPDOWN messages.

  4. I don't know if it is around anymore but we use Syslog4NT running on a
    Windows 2000 server and setup to email me via our exchange server when
    certain ISDN events occur.
