Yo tok, I think that 4th pair was for the intercom.

Basically single line set with hook flash and dial codes.
They are Enterprise size PBX's that I work on, I think they concentrate on selling the digital side of things and leave the analogue ports/sets for basic phones, faxes and modems etc.

The Panasonic is Digital and analog. The keyset can use second pair for data and first pair for voice or it can use the second pair for data and voice, with digital sets. People want buzz words, people buy buzz words. People love marketing, even if they say they don't.
Why else would rational people pay 60 grand for a Chevy 1500 pickup with a welded on top, bunch of sound deadner and glued on plastic parts that Marketing call an
Escalade??

the ports on partners may be analog but internally the voice is digital for switching purposes, right ?

Nope. They are considered an EKT. Electronic Keyset Telephone. That analog center pair is controlled via digital means BUT it's still analog. The Panasonic Digital system uses seperate ports and pairs ie the digital phone is a true digital phone and the analog port is seperate.

1pair doesn't allways mean digital, time and space division PBX's have allways used a single pair. They process the call with a microprocessor ,the phones are analog .PBX Public Branch Exchange.just a small version of a C.O.

I remember the first time I saw a digital 1 pair telephone. ROLM was trying to sell a system to a large college whith multiple buildings and old BELL cables that were bridge tapped all over the place. We tried to tell the customer that he would have to recable the campus or dut out the bridge taps but the ROLM salesman got really upset with us. We recommended he get an engineer in on the project. The engineer traveled 3 hours for another meeting with the customer and when he found out the cables were all bridged he blessed the salesman out right in front of all of us and walked out.
