I am new to the forums and this happens to be my first post.
I wanted to know demarcation point type jack is used in a residential house, that will probably never exceed 2 lines. To further explain:

I plan to wire 3 rooms, using cat 5e for phone. Each run will be will be terminated at the Demarc. What I used to see and don't anymore is a module that connects to phone company line in and joins up to 5 different runs. Is it still available at like graybar?

Questioning my reasoning, I don't see how a 66 or 110 block could be applicable, into tying 3 runs into 1 line.

I plan to have other jobs but would like to do it right and use the same type of materials. I have been cabling cat 5e for a long time but never ventured or focused on telephony wiring.

Please forgive me if my terminology is not accurate, still learning.

I do know better than joining a bunch of wires and electrical tape them though.


Best regard,
