Is there a way to transparently extend a channelized or unchannelized T1 accross a 45Mbps Frame-Relay or ATM WAN link? Scenario: Two phone switches that can be connected by a T1 link, whether analog trunking or using other methods, and I have two 7204VXRs with T1 CSU's installed. PBX T1 to 7204CSU, then to the other 7204 (over the WAN), out its T1 CSU to the other PBX.
PBX ----(T1)----router------45Mbps WAN link pvc-----router----(T1)-----PBX
Rather than order a T1 from Nashville to Dallas (for obvious reasons), I'd rather extend this over Frame. Possible? If so, is there a link to configure it?
