How to Bridge One Incoming Phone Line to Multiple Subscriber Drops

How to Bridge One Incoming Phone Line to Multiple Subscriber Drops
Use 110 block and bridge it.

The procedure looks like this:

(1) terminate your incoming phone line to 110 wiring block
(2) terminate your cat5e drops to 110 wiring block
(3) attach 110 connecting blocks using 110 punch-down tool
(4) run and terminate one piece of 2-pair cross-connect wire along the 110 connecting blocks, connecting the blue pairs. In this way you bridge (or parallel) your incoming line to multiple drops.

Please keep in mind that you can not bridge as many drops as you want. Below is the guidelines:

To determine the maximum number of analog devices that a single line can support, it is necessary to calculate the ringer equivalence for all the devices which will be connected to the line. The ringer equivalence of each device is marked on the unit. The total ringer equivalence of all the devices connected to a single line must be less
that 5.0, or else none of the devices will ring. Most new electronic phones have a ringer quivalence between 0.25 and 1.0, which allows from 5 to 20 phones to be plugged into a single line. Older phones with mechanical ringers generally have a ringer equivalent of 1, which would allow only 5 phones to be connected to one line.
