Try to loop 1st the E1/T1 card at intface1 or dir1, the LED of E1/T1 crd should turn green or orange. if its green then dir1 is active, the rest is inactive; but if it is orange inactive the rest interface except interface 1. Now check the branching table, you should allocate the OMU, TRX and TRXSIG base on what is given from NOC, since it is PCM ok. Hope this will help to solve he prob.
