[comp.dcom.telecom] Help! 2500SM Set Wiring

Well, I found a perfect 4A speakerphone at a ham radio flea market
last weekend. Thanks to all those who suggested this!!!

I ordered (and received) - an AT&T 2500SM single line phone to get
full features (on-hook dialing, etc). I paid $40 for the 4A and $70
for the telephone - not bad considering the 4A lists for $340.

But, when I opened the 2500SM today, it did not come with a wiring
harness.  I guess I'll pick up a ten lead cable at Radio Shack
tonight. But here is the problem. The instructions I have for the 182
connecting block don't give the labels of the connections inside the
phone. I checked one at work today, and copied where the wires go, but
that phone was cabled up with a 25 lead connector - not lug-ended
leads.

So, does anyone know where the 182 SIGNALS go to in the phone:

TIP
RING (these are easy!)
A1
R1
T1
P4IR
P3IT
LK
AG

(I know what some of these do, like LK, and AG short out when the
phone is on-hook, etc. But if anyone can help thanks in advance!)
