All,


Can you help? I am trying to provide backup to a remote site and the second line has been presented with a G.703 signaling on a RJ-45 interface. A few months back someone on here recommended a VWIC2-1MFT-G703 module. This module doesn't work with a 1721 or 1841 router.


Any ideas on how to get this working? The module shows in the hardware profile but doesn't show when you do a sh ip int brief.


Thanks

Hello Isaac,

it should be a question of IOS image on both routers.

C1721 can support the module for data only but it is what you need.


see

see table 1 you need at least


12.3(14)T on 1721


to see the corret image you can use

Hope to help

VWIC2-MFT-G703 is not supported on the 17xx platform but VWIC2-MFT-T1/E1 is supported

Conflicting information on the data sheet for both of them :-)


I think the best way would be foe him to upgrade the IOS and test

Many Thanks guys. I only have the 1841 running 12.4(1c). I will power on the router and define the card settings and see what happens

The router sees the card now. I installed with default values. The alarm light is on (no line is connected at present) but what I am worried about is timeslots. I sued 1-31 (default E1 since I do not have any info from the providers). I hope this works when I send it to the location.

The G703 module supports both framed and unframed..

The timeslots configuration is fine if it is a framed circuit. If unframed you can use

channel-group 0 unframed which provides 2048kbps
