I have an 11 pair cable running to a remote area of my building. I would like to install 3 merlin phones from that cable. Since that normally requires 12 pairs (4 per phone) I would like to know if any of the pairs are common to all extensions so perhaps I could get by with the 22 wires that are already installed.

It has been awhile, the brown pair pins 7-8 can be removed, it controls a feature that I can't recall at the moment what it is. Want to say handsfree possibly.

There was 11 and 16 pair cable, much dating from the time when OSP cables included a spare pair for testing.
I don't think sharing power between ports will be an option, especially over a long cable run since the ports include power limiting resistors to prevent overheating. Yes, you can skip the white/brown pair for the stations but you'll lose the handsfree answer on intercom. Calls to these stations would have to be via intercom ring mode.

If the cable in fact will work send 2 merlins, and if you can find a merlin opx card you could make the 3rd phone a cv ??
