Does anyone know of a way to pass a Ds1 through the PBX? I'm referring to bringing a T-1 into a DS1 card in EPN2 and sending it back out of a DS1 card in EPN3. I have an application where I have fiber between 2 EPN cabinets, plenty of BW, and the need for a DS1 "tie line" between 2 non-pbx devices located in the same rooms as the EPN's. -CL
