Thanks so much for the input
Background--I am primarily a wire person, not very experienced with phone switches/voicemail . I got an urgent call that a company was being evicted and had 30 minutes to disassemble there switch/voicemail, dsl gear etc.
The KSU is a Nortel Meridien. There were 8 C.0. lines at old location and 12 hand sets. I am assuming it is a 8x24 or 8x16 model.
I prewired the new location today, and cross connected the handsets and borrowed a live circuit from a neighbor suite to ensure that I had the right x connect, and I did (was able to dial out on line 1) tommorow Bell comes to install the 7 circuits ordered.
Voicemail is a star talk system. Inside the door were 2 rj 11 plugs, one marked 2 and the other 4. The technician who installed this before, had a rj 11 plug installed in both sockets, so I am assuming it was hard wired with 2/4 being used. I hope this helps, and I have no documentation from the owner of the switch. Fortunately I do have a copy of StarTalk setup and operation manual. If this helps any, I noticed the date manufactured was 1999.
