I have the following configuration:
I have a 1760 with a VWIC-2MFT-T1 and i have a 3745 with a VWIC-2MFT-T1. They are connected together with a rj48 crossover cable. They are both configured with SF framing. i want to be able to send traffic between the 2 routers to confirm that the cards are working. When i thought i had it working i kept getting RAI detected and the interface was going up and down. Any help would be appreciated. Thanks in advance
 
Post a sh run int whatever from both.

Why not use b8Zwhatever framing (default)?

I don't care what the end result or config is as it won't be out to the internet. I just want to be able to send traffic out and make sure that the other router see's it to confirm if the card is working.

This is the config of the 1760

well from your config, you 3745 is not set up correctly... you need to do your timeslots for a T1 with the same channels as your 1760 so that it will actually create the serial interface.

on the 1760, you have a multilink created but there are no serial interfaces attached to it?

Do this..

1760

conf t
int multi 1
no ip add
shut
int s0/1:1
ip address 192.168.1.1 255.255.255.252
no shut


3745

conf t
controller t1 0/0
linecode b8zs
channel-group 1 timeslots 1-24

int serial 0/0:1
ip address 192.168.1.2 255.255.255.252
no shut



once you make these changes... you will want to a very heavy packet extended ping test on the card so that you can do a show interface on the serial ports to verify if they are getting any type of errors...

First off thanks for all the help. I put the commands in that you gave me. and i'm getting the following errors.

on the 1700;

clear counter s0/1:1


on the other;

clear counter s0/0:1

Then do a ping from the 1700 to the other router

now do a show int serial <insert card for that device>

You should get something like below, and the area that is bolded is what you should be looking for. Another option is to through a loopback plug into the port and run the same command as well.
