I have a PRI that my customer wants to switch to a T1 to break it up into two seperate trunk groups, using the same hardware(Dual T1 card,CSU,..etc). Other side in a DMS250. The DMS tech says his system is set up for Wink, other choices were loop,ground, and immediate. I could not get the T1 to work. Went thru many combinations. TIE,DID,COT,WAT with EM4,EAM,... I even tried setting them up a loop and ground start. Nothing worked. He just kept saying all he saw was a constant siezure and I would see the same most of the time but, saw idle condition a few times. It works great a a PRI.. Does anyone have a Basic T1 interfacing with a DMS that could help?....It sould have been simple...
