I have a quick question about connecting something to my BCM phone system. I had just recently bought a Indyme MTS messaging and telephone server. I’m wondering if someone can point me in the direction of a wiring diagram. I have one at my place of employment that’s connected to a 66 block that’s not in use anymore but it’s to complicated to trace with all of the wires. Any info would be cool. Thanks, Jared.

I would presume you need to speak with Indyme or read its install manual to see what is required such as digital or analog station ports and which systems it is compatible with.

Note that all documentation is on the BCM itself for download which would include the wiring diagram.

Basically starting left to right is 4 Analog Trunks, 4 Analog Stations with some spares and paging, MOH etc then the last 12 are Digital Stations.

Edit: I refer to the more advanced BIX which came out over 40 years ago, so for the ancient 66 Block that would mean "starting from the top"

It appears that is does use Analog Station ports then that would be BP 5 to 8 or Wh/Slate to Red/Grn

Excellent, thanks for the info!!

I just narrowed it down even more while you were posting, see me previous post.

Awesome, I really appreciate it!

Just out of curiosity, can you PM me the link with the info you told me about with the connection to the BCM from the MTS server with a 66 block? I looked everywhere for a install manual but had no luck. If this is possible that would be awesome! Thank you!

Per my first post you need to contact the people whom make the Indyme MTS messaging server and acquire documentation from them for the particular model you have (you did not mention model).

There is no documentation on the BCM to connect the MTS as they are not related to each other.

The BCM is it's own Telephony Server with it's own Voice Mail system, 3rd party voice mails usually connect via it's analog ports or the digital ports via the VMI module (Norstar models)

So you need to find out what Indyme MTS messaging server requires for connection (Trunks, Analog, Network, SIP etc) then read the BCM docs to see it's diagrams etc.


BCM documentation:

The BCM OAM network port is IP 10.10.11.1 Subnet 255.255.255.252
That would be the first port from the left.

If you change your laptop IP to IP 10.10.11.2 Subnet 255.255.255.252 then connect to the OAM port and enter 10.10.11.1 in the web browser (IE 11) you will find all the software and docs.
You will need to login with nnadmin and the default password (if left at default).

BCM Installation and Maintenance Guide, then look for RJ-21 telephony connector wiring chart

Will do, Thanks!
