hi
1st try cgecking if the card is responding or not by using a loopback E1 cable
as the following:
1st RJ    2nd RJ
 1               4
2                5
4                1
5                2

the check controller up (looped) or down by sh controller e11/0


if up,, then double check the cable pinout between the router E1 and the modem,,

if you are using SHDL modem then the pinout will be :

----------------------------------------------------------------------
         
RJ-45 Pin (on T1/E1 PIC)             DB-15 Pin  


1                                                                      11        
 
2                                                                       3        
 
4                                                                       9        

5                                                                       1
