Try checking the terminations - you MUST have 100 ohm resistors across both TX and RX pairs. In fact, on short cable runs you are sometimes better off with 50 ohms to simulate the 100 ohm terminators expected at each end of the bus.

Hi
I have a small ISDN PABX , (BRI) at home - Siemens Gigaset 4175 which has cordless DECT extensions. I have set up asterisk on FC3 with two HFC cards and I am using the latest bristuff. I am trying to use * between my ISDN line and my PABX.
One card is in TE mode and can receive and make calls OK. I can make and receive external calls to a SIP phone. I cannot get the other card to talk to my PABX. It is in NT mode. If I try to call a PABX extension it rings but drops the call after a few seconds. The PABX logs the call as a 'missed call' I get the following debug:-
I understand Linux better than ISDN. Can anybody interpret this for me please :-)
