Split Voice & Data channels on internal CSU

I have a 2600 router with internal csu/dsu T1 WIC:

If I have a T1 line coming in from Telco which is giving me Voice on the first 12 channels and Data on channels 13-16. If for some reason I don't want to split the T1 and simply ignore the Voice channels, is it possible to simply plug that T1 into the csu and configure it use channels 13-16? At this point I don't care about the Voice on first 12 channels.

Re: Split Voice & Data channels on internal CSU

Yes,

Under the interface:

service module t1 timeslots 13-16 speed 56 | 64

If it's a controller then:

channel-group # timeslots 13-16 speed 56 | 64

If you're going to be doing voice in the future you'll need a drop/insert VWIC.
