the big boss has had a revelation; the receptionist area (which has been in place longer then I’ve been alive) is in the wrong part of the office, and must be moved before OCT 1st.

skipping the long convoluted argument with the site liaison, the end result is i need to understand the pin out of the SL-1 card and the M1250 attendant console. here is the ATT record from LD 20:

TN 017 0 08 00
TYPE 1250
CDEN DD
CUST 0
SGRP 0
SETN 017 0 08 01
ANUM 01
ALPD NO
SSU
ICDR ICDD
ABAN ABDD
CPND CNDA
AADN
DNDI DNDD
KEY 00 BVR
KEY 01 BIN
KEY 02 DCW
KEY 03 DPD
KEY 04 DPS
KEY 05 PAG 700
KEY 06 PAG 710
KEY 07 PRK
KEY 08 ADL 4*250458
KEY 09 ADL
DATE 22 DEC 1999

TN 017 0 08 02
TYPE PWR
CDEN DD
DATE 30 JUL 2001

TN 017 0 08 03
TYPE PWR
CDEN DD
DATE 30 JUL 2001

this looks like 4 pair: 2 power (17 0 8 2 & 3) and 2 data (17 0 8 0 & 1)
can anyone help me translate this into the DB25F that connects to the back of the M1250 console?

It's for a M2250 and a CIU . should be the same for a M1250.
On D25 connector.

The first TN must be on pin 14 (+) and 2 (-)
The second TN must be on pin 15 (+)and 3 (-)
The PWR (+) on pin 17 and 5 and (-) on pin 18 and 6

points for you dude, thanks.

i managed to find the pinnout to the centronix 50pin and just before the deadline, but they decided to change plans at the last second.

however, with this and the engineering guide part 3 i can document the centronix 50 to DB25f cable in the event it ever needs to be replaced, which might be soon, considering it's been wheelee-chaired a few thousand times.
