I'm just back from the client's site and failed to perform any tests.

When connecting with a straight cat5 cable to the telco's E1 socket I 
got a red status led and RED alarm on the TE410. However when 
reconnecting the PBX's cable, the telco's socket led went back to green.

On the other hand, I tried connecting the PBX's cable to the  TE410 and 
got a green led and REC status. 

What could be wrong?
