Moved to facility with Definity PBX. One group wants to keep using their old key system. Have KSU and FXS channel bank from old offices and found spare TN767's left over from upgade of PBX. I've tied PBX's together using T1's and connected channel banks to CO T1 lines, but before I maybe waste time experimenting, I was hoping to find out if the Definity can emulate a CO to work with the channel bank. If possible, how would I program it? I know that I can tie the KSU trunks to single-line ports instead of a T1 line, but that would mean the purchase of a single-line card and pulling some cable but I'm just too cheap and lazy.
