E&M Tie Line Trouble

E&M Tie Line Trouble

E&M Tie Line Trouble

Connecting 2 Norstar MICS 4.0 over a shared data/voice connection
Using 2 Micom NetRunner 75E to split the voice and data at each end

Set to Type II 2 wire circuit.
Micom has these connections:

First question, Am I correct in saying that to test the setup of the micom equipment I can put a buttset on the tip and ring and then connect the E & Sg to get a local dial tone then I can connect the M & Sb to get a remote dial tone?

Is so that works perfect.  Also both of those pairs have the correct voltages:
E & Sg  -48v
M & Sb   36v

The problem is that if the above info is correct then I have something set wrong in one of the MICS systems.  From Either local or remote when you dial the trunk access code you get access to that tie line, but it is only dead silence.  No stuttered dial tone.  So of course they time out or dissconnect suppervision.  I have both trunks set to E&M and both are set to auto answer and answer with DISA.  The only option I not sure about it Signal.  It has there options.  wink start, immediate, delay dial.  Which option will I need or should it matter and do both systems have to be the same.  Other than that I have not changed any other settings in either system.

I have been working on this setup for three days and I can't seem to get anything to work.  Any help or suggestions would be very helpful.  I have read past posts and have tried to understand E&M type II circuits.
