It depends on whether you are using a WIC with internal CSU or a WIC which need external CSU.
Most CSU should have default configurations, put in, except for the channel definitions (usually will be set to full T1 - all 24 channels on), so that its just plug and play. Just to make sure, you might want to check with your service provider, what the coding, timeslot (ascending/descending), framing, linecode etc is.
A sample command to set 256 on your T1 line would be,
Even when getting bandwidth totalling less than a T1, it isn't always the case that only a subset of the T1's channels are used, right? We've gotten 5 or so 256K frame circuits of late, all brought in via T1's, and only in 2 cases was I required to tell the router which channels to use -- the others worked with the default of all channels.
Anyone know what determines whether or not only some channels are used? Is it just the carrier's preference?
