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.
