It really is SLC 96. Subscriber Line (Carrier? or Concentrator?)

Think of a T1 channel bank like device designed to be stuck out on a
concrete pad in the boonies (-40C to +65C rating), or in the cellar of
an urban high-rise. Think of it as remoting a piece of the CO out on
the end of some digital facilities. It can handle single and multi
party, coin, VF special services, and up to 56kb data. Can use copper
T1s, or fiber at T2 (4xT1).

It operates in three modes. 

Mode I uses four T1s to 96 subscriber ckts (full availability) with an
optional 5th T1 hot standby. The single + multi party plug-ins are two
ckts per card, thus filling the box.

Mode II Concentrated config. Uses two T1 (48 ckts) with an optional
third T1 hot spare to serve 96 subscribers with a fixed 2:1
concentration for single and multi-party lines. In this mode it can
also support up to 16 special service circuits that are NOT
concentrated, and their ckts are one per card.

Mode III Special services ONLY using two T1s with optional third T1
spare.  The 48 possible ckts, at one per card fill the system.

Perhaps you would care to order the doc + practice set: 700-546 SLC-96
Documentation and Practices - seems to be only $3.25 (may be typo) in
a distributor's catalog. The Schematics are: # 700-548.
