SPID

[Ahmede]

When the main frame goes down and the backup ISDN tries to comeup we are getting "invalid spid" error message.. The carrier confirmed that the SPID number we are using on the router is correct but we still getting the same error.. Any Idea what could be the reason?

The carrier told us to check the SPID number on the modem? Which modem?

Thanks in advance

Has it worked before?

Sometimes you have to put additional digits after SPID e.g. 0101, as far as I remember, for Verizon.

thanks.

Can you please provide the configuration of the ISDN. If the ISDN is terminating to an external ISDN modem, then you will have to check its configuration. If going to the router then you can do a SHOW ISDN STATUS to see if any ISDN layer issues. Also you get good info from the DEBUG ISDN Q921 and Q931 commands....
