SLC*96 (trademark of AT&T) is a 'Subscriber Loop Carrier - 96 lines'.
Also called a pair-gain device, it performs analog to digital
conversion on up to 96 telephone lines and transmits them over 8
copper pair (4 digroups) to a central office switch.  It is an
environmentally hardened channel bank, or time division digital
multiplexer with analog interfaces.  Nothing to do with 9600 baud...
but a reasonable guess!
  
It can do a lot of neat tricks, but none that are accessible to an
end-user.  SLC*96 is now being replaced with SLC Series 5, which
performs essentially the same function but in about half the space,
and Northern Telecom's DMS-1 Urban, which provides additional
pair-gain savings through a concentration function.
