Motorola Advanced 911 Phone Schematic

[etothejtheta]

I'm working on a 911 dispatch console system. The current system uses Motorola Advanced 911 Phones. I'm trying to interface a phone to an audio distribution box that ties into the system. Does anyone out there have a schematic for this phone? I understand this phone is from the early 1990s. Any help in locating the phone schematic is much appreciated. Thanks.
