Reverse Engineering a Paging System

Guys -

I'm a Cisco guy trying to decode a Nortel paging setup connected to an
ancient overhead paging system. I'm trying to figure out what type of
port it is since I can't find documentation on the paging system.

Here's the output from the PBX:

TN 030 0 00 00
TYPE PAG
CUST 0
XTRK XUT
TIMP 600
BIMP 3COM
RTMB 2 1
SIGL OAD
STRO WNK
SUPN
AST NO
IAPG 0
CLS UNR DTN CND WTA LPR THFD
P10 NTC
DATE 7 NOV 2002

Is this an E&M Wink trunk port? I'm assuming its two wire since that's
what's connected to the paging system.

Any help is much appreciated!
