It looks like this might be the system that you are talking about

Scanner Frequencies: Southwest Regional Communications Center Trunking System, Cedar Hill, Texas

If that's the case, it's a MPT-1327 system which is apparently not easily monitored. There's a discussion in this thread:

Mpt 1327

I think the people in that forum can help you figure out what you need.
