I've recently purchased two 1760-Vs to connect Mitel SX-2000 Light PBXs that are currently connected by a point-to-point T1 (DPNSS). As far as I can tell the feature that I need to connect these is Transparent Common Channel Signaling. However, it seems that T-CCS isn't available on the 1760-V. Is this the case? If not, how do I enable T-CCS? Anyone know if T-CCS will be added to the 1760 in a future IOS release? Should I try and trade in these routers for 1751-Vs?
I'm assuming you're attempting to keep the Mitel specific features working - thus your need for T-CCS.
In my experience, the 1760 might not have enough CPU to handle a full T. I've done this on 2621XM's, and a full T pins the CPU at about 25%. If the commands are there, you are free to try, but I wouldn't set hopes high.
You may have better luck trying QSIG or plain old PRI if some features aren't needed.
Not sure about this. I don't think the CPU usage would be that much since we are just opening a clear channel to the Other end and the DSP is effectively doing most of the work. 25% isn't that bad especially if that's all the box is doing. It's when you get up around 80% that you really have to start watching things.
