Hello, we're looking to hook up a PRI but don't intend on using all 24 channels of it.
Our current setup is a Cisco 1751 router with 2 DSP's, enough to cover 12 channels. (It also as a WIC-1DSU for data)
My question is, if I conifigure the VWIC to support only 12 channels of the PRI, this won't hurt our service will it? Like dropped calls because the rest of the channels aren't in service.. The telco assumes we're using all 24 channels, but we won't (unless we up our DSP's).
Also, if I want to configure it to only use the 12 channels, how does the D channel work with that? Would that mean I'd really only have 11? Is there an extra command on the controller that I'd have to specify the D channel, or just configure the "pri-group timeslots 1-12"??
One more question.. Do you think having the WIC and a VWIC in the same router is an overload for it? I wouldn't think so since it obcviously supports it, but for some reason whovever setup this network put both a router and a vg200 gateway in this really small office (VG200 has 2DID ports/1751 has 2 FXO's and a WIC). Suppose they (some vendor) were just trying to milk it for every penny.
Looking at the product description thought of the VWIC-1MFT-T1 card I need. It says it uses channel 16 as the trunk signaling channel. Does that mean I have to include 16 in the controller configuration?
