Most new, residential construction these days is done with a dedicated 4-pair
for each outlet in the home and extended to a common area, usually near the
furnace. The same is done with prewired coax.
Then, a SINGLE cable is run from that bundle out to the SNID or CATV box on
the outside of the premise.
If adding a "leg" to this "hub"-type of network (phone or TV), it is
preferable to begin at the bundle rather than the box on the outside of the
Different telcos use different manufacturers for their SNIDs.
The customer side SHOULD be clearly marked (embossed/raised-letters visible
even through a coat or two of paint) "Customer Access". A common, flat-bladed
screwdriver should open it. If it has not been opened since last being
painted, it may take a lot of banging and coaxing to break the paint "seal".
Regardless, the customer side will be more easily "unlocked" than the telco
side which should require a special tool. Good luck!
My box is too low and stuck in a corner, or I am too old to get down
that low, to read what it says on it. :)
But mine works so: One standard screw has to be loosened to open the
cover on one side, and only after that is open can the second cover be
opened because the first cover overlaps the second cover.
So the first cover is for the customer.
The second cover has something additional keeping it closed, and I've
never tried to open it. There isn't much in there, is there?
It will vary from one NID manufacturer to another. The customer side is
the one you can open without a can wrench. Just unscrew the screw
labeled customer access, open the cover, and the terminals thus exposed
are the customer wiring connections.
