Router does not reestablish link after satellite takes a hit 1

Ok i have a cisco 3640 router that is configured to connect to a satellite network through a modem. Everytime the satelllite takes a hit we have to restart the modem to get the circuit back up. Nothing is wrong on the satllite side since every othe customer seems to be running fine. Currently we have a constant ping running between the router and our connection to the satellite connection to act as a sort of keep alive.

we also have a redundant 128k leased line connection that is supposed to automatically come online in case of any loss of connection to the satellite

Is there a way to troubleshoot this? I'm thinking that there is some problem with the router keep alive that it sends. Can anyone help me??? My current configuration is below



Current configuration:
!
version 12.0
service timestamps debug uptime
service timestamps log uptime
no service password-encryption

when say modem, do u mean satellite modem..?.. say like an EF DATA SDM-300A satellite modem?

 
Try changing your route metric for serial0/0 to 10. Setting it to 255 basically tells the router to never use it. Also, in the route statement, try using the next hop address instead of the serial port number.
 
thanks that worked...

a couple more questions (i just started here and the place is a mess lol)

1. the back route is our redundant connection but a diff ip network current the dsu/csu for that connection is directly in the switch. everytime the sat goes down we have to reconfigure our web server nat server etc using the 196. ip addresses. how do I set it up so the switch inconnections is transparent?

2. I'm trying to verify if my router acts as a dce or dte. the cable going to the modem is a db60/db37 rs 449 serial cable, with the 60 pin end (which is in the modem labelled as dte.

thanx guys i really appreciate the help
