It's funny you say that Ed, because that's exactly what I was planning to do! lol! I'm not comfortable spending $29 for the connecting block when I already have a couple of 66 blocks around I can use.

Arthur: Is there a possibility of damage to the equipment if I use a 66 block instead? I'm assuming that so long as I follow the wiring diagrams I should be good to go. You said you didn't want to potentially start a war, so you're welcome to shoot me a PM with an explanation if you're up to it. I'm always looking to learn more about this stuff.

Thanks all,

Scott.

P.S. I ordered a brown wood grain Satellite speakerphone set last night, and I sent the eBay seller a message asking if he had any Master sets around.

I found a 91B in my collection, what is that adapter for?

Jeff:

"A typical system involves at least a Primary set, zero or more Satellite sets, and a 91A or 91B "connecting block" which interfaces the Primary set to the CO lines, and any number of optional Satellite sets.

Do you have any use for one? It's just collecting dust here.

I have a few 91B. You can have one when I find them.

The reasons for injecting the CO dial tones using the BSP method:

Conformance with USOC rules: the subscriber needs to have access to the network interface, in this case the RJ11 or RJ14 that plugs into the primary block.

The primary sets send system power back to the satellite sets via the violet leads. If you send T & R to the primaries on the violet leads in a running cable, you prevent the system from getting its maximum available power.

If the phones in the system gets moved around, the installer has to go back and figure out which 25-pair cables to use to re-assign the dial tones.

If you don't, the Antique Telephone Police will storm your house and arrest you.

etc, etc, etc.

not the Antique Telephone Police!

LOL I had to laugh. Maybe it was the Phone Cops?

NO ONE... expects the Antique Telephone Police.

Jeff: I would appreciate it if you don't need it. PM me please.

Arthur: Thanks for clarifying!
