I have a two-year old message sent out to AT&T sales regarding the
proper termination for analog data lines.  According to this message,
"The JM8 is intended to be the standard termination for analog data
services."  I've also heard the JM8 described as an 'eight-pin
mini-modular jack'.

An accompanying list shows all the RBOCs accepting specification of
"JM8" or "8MMJ". Some of the other independents - Centel, GTE, and
Southern New England Tel - were still using the 42A Connect Block.
This is apparently an older standard, and since the message is so old,
they may well have changed since then.

As a telemarketing type, I don't get to go out and see my customers.
(They're mostly 500-600 miles away!)  But I'm told that Bell South
installers usually terminate analog dedicated circuits in a device
called a 'Teleport', which provides the JM8 as well as some other
options.
