DCS Over TCP/IP for Voice calls via PSTN?
DCS Over TCP/IP for Voice calls via PSTN?
(OP)
Hi All
I have administered a DCS link via TCP/IP between two R9 switches; the DCS link is up and in service.
I would now like to use the DCS signaling across TCP/IP for voice calls to the far end switch via a PSTN E1 circuit.
It would seem that even though I have a DCS link up I am unable to Tie this to the PSTN E1, I cannot administer the E1 for DCS operation as it then asks if the DCS signaling is using the d-channel or BX.25 and also more importantly it is a PSTN trunk and out going calls will not always be to the far end Definity.
Any ideas?
Cheers PBX

Thank you Chris for the response, the Far end PBX does not have IP trunks enabled, I have not set up a signal group as the DCS link is administered in the ch communication Process.

As you can see the DCS link is up, but how do I Tie it to call setup over the PSTN??

Thank you Chris for the info and I will be interested in what you dig up, you are correct in assuming that Qsig is not turned on, we do not have any point to point E1s to run DCS across the d-channel and IP trunks is also not turned on in the far end switch.
Even though the DCS signaling over IP is up and running between both switches the problem appears to be that, this type of DCS connectivity has no way of tying to a call setup over the PSTN, what I thought and hoped would happen is:
Calling party at the near end PBX makes a call to the far end, in the near end aar ana table the dialed string is recognized as a call to far end DCS node:xx
The PBX signals to the far end PBX via the DCS IP link that a call is being made to extension xxxxx
This im not sure about but "hope" would happen: The near end PBX then marks the out going call setup using the IE's in layer 3 which is recognized by the far end PBX and Ties it to the DCS information sent over IP.
That's a BIG hope
Look forward to what you turn up Chris.
Cheers
