Depends on what box they get from AT&T. If it is a Cisco 7500 good luck as I am still looking for codes for that. The Pace ISB is the same. No good codes out there. The Cisco "slave" box can be done with just learning the remote with the RTI reader. That one works fine with a T2c so far. If you find codes for the Cisco 7500 polease let me know.

Thanks
