AT&T-LL has had two 4ESS switches in the Denver CO area for many years
now; previously they had several 4A Crossbar toll switches in the
Denver CO metro area.
DNVRCOZJ05T (aka DNVRCOZJDS4) installed Nov.1979
"Zuni" at 52nd and Zuni Streets
I don't know if this particular 4ESS has been removed or if it is
still in use.
DNVRCOMA16T (aka DNVRCOMADS8) installed sometime around 1998/1999
"Main" at 14th and Champa Streets
The "Main" building is probably shared use between AT&T-LL and
Qwest/USWest (and other more recent co-located cellular and CLEC
providers). I don't know if Qwest/USWest has anything at "Zuni" --
this one MIGHT be strictly an AT&T-LL facility.
AT&T-LL has had a network management facility in Denver CO for many
years, but I don't know if this is still in use "as such" -- some
years ago (late 1990s?), "active" network management for AT&T-LL was
supposed to have been discontinued at Denver CO (Zuni?) and Conyers GA
(old "Rockland GA" facility in Rockland County, outside of Atlanta GA)
with all network management/control was supposed to become fully
centralized in New Jersey (Basking Ridge? Bedminster?), but AT&T-LL
still maintains major network operational functions at both of their
long-established Denver CO and Conyers GA locations.
AT&T-LL also has an 5ESS-OSPS (Operator Services Switch for Card,
Collect, Person, etc. services) in Denver, DNVRCOMA15T, but note that
this is at "Main", not "Zuni". I don't know if AT&T-LL maintains an
actual "Operator CENTER" in the Denver CO area -- where there would
be actual live human OPERATORS -- the OSPS at "Main" I'm referring to
is strictly an automated switch for operator/card functions, which may
or may not have actual human operators located there.
Also, AT&T-LL has installed 5ESSes, DMSes, and other switches all over
the US in addition to their traditional 4ESS (and 5ESS-OSPS) switches,
so it's also possible that there are one-or-more 5ESS, and/or
one-or-more DMS switches at "Zuni" (and "Main") for AT&T-LL (as well
as such switches owned/used by Qwest/USWest at "Main").
