Issue with Netvanta 7100 and PRI from carrier

I have installed a 7100 and the carrier is using switch type DMS 100. On outgoing calls when the call is answered it drops. incoming calls drop automatically. The carrier is saying everything is ok on their end. I was told that the carrier is setup for NFAS which is not supported but the carrier is saying they are setup for 23B+D. See the debug files below. Any suggestions?

Re: Issue with Netvanta 7100 and PRI from carrier

The ISDN message below shows that the carrier equipment is configured for NFAS.  NFAS is not supported in AOS.

In the Call Proceeding message, octet 3 has  the Interface ID flag set to EXPLICIT, and it is followed by octet 3.1 with the identifier.  The NI-2 spec (SR-4994) explains the use of octet 3.1 – it is not used when there is a single T1 interface.

Re: Issue with Netvanta 7100 and PRI from carrier

Hi Charles,

Thanks. Please forgive me because I am relatively new to this. However I just want to ask since you made reference to the NI-2 spec would it make a difference since the switch type is DMS 100? The last time we had an issue with the demo system I think you had changed the switch type and it worked (I stand corrected) can that be possible?

Re: Issue with Netvanta 7100 and PRI from carrier

Colin

NFAS is an option that can be configured on both ISDN switch types, NI-2 and DMS100.  So switching between the switch types will not resolve this issue unless NFAS is disabled.

Thanks,

Charles
