How do I wire up an E&M Port to a Nortel Norstar MICS? I am trying to connect this E&M to a cisco VOIP 2610 VIC-2E/M Card

I followed the MICS guide on wiring 2 ports for type 2 on and E&M Module. Currently I have a single MICS System and my E&M Card is in Port 3 of the MICS system. I have the 25 wire Amphenol Cable wired up to the second port which is the telephone and auxillary port. The following is my wiring configuration for 2 ports:


RJPIN  Service Wire-Color
PORT1
1 SB Brown-White
2 M  White-Brown
3
4
5
6
7 E White Green
8 SG Green With

Port 2
1 SB Green Red
2 M Red Green
3
4
5
6
7 E Red Orange
8 SG Orange Red


Also http://www.cisco.com/en/US/products/hw/gatecont/ps2250/products_tech_note09186a008009452e.shtml

Some PBX products (and many key systems) can only operate as the signaling unit side of the E & M interface. This means that they cannot interoperate with the Cisco E & M interface if Type I or Type III is chosen. If Type II or Type V E & M is being used, PBX products fixed as "signaling unit" side can still be used with the Cisco E & M interface via Type II or Type V.

This is why I have chosen type 2 cabling, to my knowledge the MICS is a Key System correct? Not a PBX?

I just updated my pin configuration

Looking at the pin out from the website

For the nortel MICS Manual Page 176 I am looking at the section where it says TC Slot. Right now my Trunk Card is in Slot 3 but I am not sure if TC Slot means trunk Card. Also my 25 Amphenol cable is plugged into the ICS telephone and aux port.

I didn't even realize this but I need a trunk module, on page 135 of the manual and page 131 of the manual, it states that the E&M card can only go into the trunk module slot. I am not sure if that means I can't stick the the E&M Module into the ICS Slot.

In regards to what slot, the only cartridages that can be used in the MICS and the Trunk Modules (TM) ar ethe LS/DS, BRI and CI. The T1 cards must be installed into the ICS slots only, slots 3 or 4.

In regards to the TM: cartridges LS/DS, CI, BRI, E&M, DID can be installed in any slot.

Yes it even says that E&M can only be installed in a trunk module and not the KSU (main MICS Unit). So now I am going to have to wait until the trunk module I am ordering arrives...

Joel_SiskoCommented:
In regards to wiring, I will double check on the exact, but in the meantime you have three amphenol connections on the MICS, from the top down:

First one supports the first 24 digital stations
Second one supports 8 more Digital stations plus auxillary connections (page port, MOH)
Third one supports the CO Lines

Yes I kind of figured as much, the next step will be getting the equipment the extra trunk E&M and the T1.

Joel_SiskoCommented:
Assuming that you install the E&M card into slot one of the TM, the wiring pins out as the following:

White/Blue --> T
Blue/White --> R
White/Orange --> T1
Orange/White --> R1
White/Green --> E
Green/White --> SG
White/Brown --> M
Brown/White --> SB

yup it matches my configuration thanks for the confirmation!

Joel_SiskoCommented:
Just need to make sure the above pinouts match the pinouts from the RJ48S connector on the Cisco E&M card. The best way to do this is to crimp an RJ45 onto a length of CAT3/5 wire. Wire the condductors from left to right looking at the contacts fro mthe top:

  1     2     3    4     5     6     7     8
w/b b/w w/o o/w w/g g/w w/br br/w

Punch down the other end of the wire onto you cable blocks (66/110/Bix)

Then punch down the amphenol cable dischagre from the TM onto a seperate cable block.

Now you can use cross cennect wires to connect from station block to station block.

In regards to the MICS, its a hybrid system, it can be a Key system or a PBX.

A key system is a system that the phones have a seperate key (button) for each line coming in. So 10 lines would mean 10 buttons on a phone.

PBX allows for the CO lines to be put into a pool, so this way phones do not need a button for every line, just system access buttons.

Kindest regards
