Technically, you can find this information out when you bring the link up, if you use ss7linktest you can see the debug output of the link alignment. The first routable message you receive should contain his point code (which would be the adjpoingcode and defaultdpc for most setups) in the OPC field. You can also try to get this information from whoever you're interconnecting with. That is probably the easiest way to do it. > 2.how do i check whether i have configured everything correctly ? i mean > like zap show channels in PRI world where it shows OK what will the > equivalent ss7 command ? It will work if you setup the link correctly. It won't if you haven't :-) In all seriousness though, you can use commands like `ss7 show linkset 1` to show whether or not the linkset is up (aligned). You can also do an `ss7 debug linkset 1` to enable debugging on it if you are trying to diagnose call control or protocol related problems. > 3.

Possibly. It depends on what field you're looking for in the signalling. You probably want to get a debug trace of an incoming call, show us which number in the IAM message in the debug trace, and we can tell you how to retrieve that field. If it's ANSI, and you are seeking the charge number field, there is a special channel variable to retrieve it (SS7_CHARGE_NUMBER). For other fields, there are different variables.
