i’m sure there are standing references to all this. but as i recall,
the 5ESS was a more or less local switching system.
the guts of the long distance network were embedded in the (roughly) 140 1ESS’s. they
ran
a completely separate (and substantially older) code that supported things like SS7
(signaling code
that was NOT embedded in the voice channel). the 1ESS was a complex piece of equipment.
my interaction with this was tangential. throughout the 1980-90s, i had a tight grip on
how
accounting messages were handled within AT&T and wrote some C code that handled a
a transition from one level of the standard software to another level. and that code ran
inside
the 1ESS.
but this was a long time ago.
