Nortel analog UNITY Controller Console connected to my BCM50

[GordonKapesMZ4]

So for $10 I acquired a year 1990 Unity Controller Console made by Northern Telecom. I bought it for experimentation and want to try getting it to work on the ATA ports on my BCM.

I figured it would be a simple phone that I could plug 3 analog Intercom extension lines off my BCM50 straight into the back of the Unity phone....but to my surprise, this phone has a male amphenol port, a power adpater port, a handset port and a 8 pin port on the back of the phone and nothing else. I have a power adapter cord.

Can any Nortel veterans scratch their distant past, and convey the easiest way for me to wire this up to my BCM? I have a prewired 66 block with amp. connector that I could plug into the back of the Unity phone, but where do I punch my analog pair of wires from the "telco" (in this case my BCM analog I/C dialtone) into the 66 block in order to achieve dialtone on the Unity phone?

Is there a simpler way using the 8 pin adapter on the back of the phone?

It was as simple as punching it to the white blue/blue white on the punch down block.....duh....got it working now and wow, what a difference compared to the modern BCM phones!
