DCS--VOIP Question

[nodialtone]

This is my scenario, we have two PBX's separated by some distance, 300 miles +. "A" Location is a G3V11, "B" Location is a G3V4. Is it possible to establish a DCS connection between these switches using a a frame relay circuit with VOIP? I understand there will be an issue of RTU for DCS, but will the PBX's support this. THanks

In my opinion, you have to upgrade side B in order to use VoIP.

You also need RTU for Ip-trunks and DCS and a Prowlerboard and Clan.

You can get the wics for Cisco routers that will emulate a T1 (M24 or PRI!) and hand off the T1 to each switch. The T1 is then handled by the router and passed to the far end router across your data WAN which has a similar setup. Basically, the switch is not aware that it is using IP trunking. I'm sure there are other products that will do something similar for legacy PBXs.

I agree with RFWatts, with one concern. I believe that you would have to use x.25 signaling to DCS an R11 to an R4 and I don't know if this may be a problem using T1 emulation.

Another issue I just thought of is that if your R11 system is an S8700, I don't think you can do DCS using x.25

You need to upgrade the remote switch to at least R9.5 to get good IP capabilities.

Also, the Cisco solution would work, but you won't get proper integration of the Definity switches..
