I need to program a TIE line from a Nortel CS1000M 5.5 to a Cisco Call Manager Server using QSIG, can someone tell me what hardware I need from the Nortel side, I would like to use a Dual DTI with a D channel daughter board instead of an MSDL, is that doable, and also what loads do I need to access and in what order to program the span on the Nortel box?
