[VoIP] Channel Bank on Ebay [not mine] and E&M

[Steph Kerman]

Thanks for the clarification. 

That has to be a moniker that someone invented, in other words, sort of 
a fiction.  It has no real legitimacy no matter how many people may use 
it, the way RJ11 and most others do.  Many people also refer to the 
handset jack as an RJ22, another mis-invention in this case since the 
RJ22 actually is a documented and defined interface that uses a 25 pair 
Amphenol mini-ribbon connector to connect to multiple lines.

Regardless of its popular use, RJ has a formal meaning.  It refers to a 
"registered jack" under the FCC program that was established to allow 
direct connection of privately owned equipment to the public network.  
Since the Bell System was never forced by the FCC to allow connection of 
privately owned equipment to their own phones at the handset interface 
(as opposed to directly to the line itself), no RJ was ever defined 
using the 4-position jack.
