This is the problem, any suggestions for other solutions are solicited. I have a "remote" site going into operation. T1 lines are cheap and easy in this situation. Metallic pairs aren't. I want to put up to 24 telephones in the remote site, connected to my AT&T System 75. The 75 T1 interface apparently can only be set up as a tie trunk using E&M signaling. What I need is a channel bank that will either let me connect 2500 sets to that T1 channel, or a pair of channel banks that will let me connect stations on one end to station ports on the other end. A distinct advantage, but probably not a requirement, is to be able to use my 7406 digital telephones at the remote site. Thanx, Doug
