Hi all, I'm diagnosing a problem related to PRI card. I would like to know the following: assuming I've got a working PRI card and correctly installed Linux drivers and a PRI line connected to the card, even without starting asterisk, shouldn't I hear a ring tone when I dial the number? I'm getting busy tone all the time. I'm thinking the patch cable I made may be causing this. The problem is that I've got a 2 wire PRI line connected to an HDSL modem (which has a DB15 interface) and modem is then connected to a Siemens PBX. I made a DB15->RJ45 cable according to some pinout schemes I found on the net, so that I could connect PRI line coming out of modem the digium card. It would be cool if someone could point out how to make such a cable and point out what I'm doing wrong. Thanks in advance. __________________________________ Do you Yahoo!?

PRI will usually show busy when the switch doesn't see anything on the other side of the circuit. This allows correct operation of multi-span installations where one span goes bad. Try running something on the PC which actually sets up the ISDN card and talks to the switch. Good bet that it'll suddenly start working. ...

If you tried phoning from an isdn equipment you would likely see a cause code that explained the situation better. First make sure that the lower level is connected correctly. Run zttool and make sure you are not seeing a local red alarm or any remote alarms. You may need to start Asterisk to get the span started, I am not sure. When zttool shows the span to be up you can start working on the upper layers. Peter
