Communication protocol Galaxy modem

Dear security friends,

I'm looking for a communication protocol of a security controller.
Security controller is a Galaxy system (Ademco Microtech).
On the A-B line an ISDN modem (also called a communicator)
is connected.
I want to know the communication protocol on this A-B line between
the Galaxy controller and the communicator.
I already ordered SIA format DC-03 protocol standard,
but that is the communication protocol on the outside of the modem
(from modem to ARC;Alarm Receiving Centre),
but I need the protocol on the inside.

Anybody ?
