I am having problems with the configuration of my E1 card VWIC2 - 1MFT

- G703

The connection is a standard RJ but I can't get the config to work. The router we will be swinging the E1 from is configured as such:

interface Serial0/0 no ip address encapsulation frame-relay IETF no ip mroute-cache ! interface Serial0/0.112 point-to-point ip address 124.205.120.70 255.255.255.252 frame-relay interface-dlci 112 IETF

WIC Slot 0: Serial 1T WAN daughter card Hardware revision 1.0 Board revision J0 Serial number 28155109 Part number 800-01514-01 Test history 0x0 RMA number 00-00-00 Connector type Wan Module EEPROM format version 1 EEPROM contents (hex): 0x20: 01 02 01 00 01 AD 9C E5 50 05 EA 01 00 00 00 00 0x30: 98 00 00 00 11 11 26 01 FF FF FF FF FF FF FF FF

I think we have an external CSU/DSU

Can anyone give any advice.

Thanks

I read the specs for this card from cisco and it looks like it is more used for voice applications than for data applications because of the echo cancellation features it has. What is the status of the interface? Is it up ? I don't see in your configuraiton where you are setting the number of timeslots you want to use. Even tough it is an E1 you have to specify if you want to use the whole E1 or just some timeslots in it. Perform a " service-module e1 timeslots 1-31" under the serial interface. That is if you have an integrated DSU/CSU in you router. You also want to try if the card is specified in the configuraiton with a "card type e1 " command.

IIRC, there is a command you'll want to put in IOS to "toggle" a VWIC to data mode from voice. Also depending on the router only certain slots will allow the card to exist in "data" mode.

I can't find the relevant config for you, but I remember running in to this frustrating issue about a year ago; and the above notes were the two keys to solving it.

I think you may need

controller E1 0/0 channel-group timeslots 1-31

serial 0/0:0 ip adddress etc

That I think should be

serial 0/0:15 sorry the last one I looked at was a T1.
