Be cautious when installing a bridging adapter, if the associated telephones are key sets with 25-pair mounting cords. If you refer to the appropriate BSP's, you will read the explanation. Basically, you need to insulate and store the Violet leads inside the sets that are used for on-hook dialing and talking (speakerphone service.)  If you don't you will get unwanted interaction between the sets.

Yes, I did run into this. It took me a minute to figure out that one of the phones was causing this, after isolating the problem down to one phone, I removed that phone from the mess of connections and all worked fine. I wasn't sure what was causing this and still not sure. The isolated phone however does work without any problem by itself.

For common audible ringers:

(1) Remove the red and blue straps from G+-/S+- to RG/RB

(2) Connect the 118A Freq. Gen. to RG and RB

(3) Punch down the yellow-slate/slate-yellow of the 25-pair hang-off cable to the upper left B1/R1 on the block inside the 551C.

Poplar1 - The Angels in heaven are looking down upon you. After getting this punched down the way you explained, I have given wings to many angels this afternoon, bells ringing like its Christmas! Thank you Poplar1, you have me up and running with ringers!

The violet leads are bridged, along with all the other leads. There are sneak paths between the phones over the violet leads. The BSP will explain it, and you can trace the sneak paths on the wiring diagram.
