I have a Cisco 3640 being used for remote user dial in. It has two E1 controller interfaces and is connected to 2 ISDN30 lines. This worked fine, until we had a power supply failure in the ISDN30 box. This fault has been recitifed but now the router cannot be dialed. If you dial the phone number you get the message "number is temporarily unavailable". I have tested this with some BT equipment in place of the router and it works fine. Could the power supply failure have caused the router and problems?
Any ideas would be great !

First of all we need to see that the calls are reaching all the way to 3640 over E1 lines or not..We need following debug on 3640 when you dialin over E1 lines.
debug isdn q931
debug modem
debug modem csm
debug ppp nego
along with following sh commands
sh isdn status
sh run

Switched debugging on for all except debug isdn q931 (not valid), and then dialled number. No debugging info was displayed. Show isdn status is not accepted for my code.

You seem to have lost your entire ISDN config. You need to reconfigure the controllers and the serial interfaces; I'm not sure how this would occur other than be un-configured...
