I'm not completely familiar with the telco jargon.
Does Tandem mean the same as a local central office, where
POTS lines terminate at the switch? Long Beach has a population
of 470,000. The C/Os I know of are:

A tandem office is a CO primarily used as an aggregated switch point
between local CO's. Think interconnection of local CO's or long haul

Alamitos at 7th Street and Termino, ZIP 90814

Clark near Clark Ave and Pacific Coast Highway, ZIP 90804

LongBeach at 6th Street and Elm Ave, ZIP 90802

Lakewood at Clark Ave and Connant St, ZIP 90808

LNBHCAXG at 3440 California Ave, ZIP 90807 (for my home)

That's the building CLLI, the switch is LNBCHAXGDS0.

This one is a 5ESS and serves 12 exchanges.

562-290 562-424 562-426 562-427 562-490
562-492 562-595 562-933 562-981 562-988
562-989 562-997

I see 7 5ESS and 1 Nortel SLC DMS 10, possibly a remote to
a campus or something, in Long Beach.

507 E LEW is holding the most switching gear is likely
a tandem. Um, I think this is the tandem code, PNTCMIMN50T,
and it's servicing about 20 areas.

I have no idea whether cell service was truly affected. The
announcements we sent to our campus suggested people use their
cell phones for 911 service which would be serviced by the
CA Highway Patrol (Erik Estrada, etc.) or a campus telephone
which is serviced by our local campus police (sworn state police).
I was completely unaware of the outage until someone else
mentioned it in my office.

If you know of an NPA-NXX of a cell phone that was impacted,
send it privately and I'll tell you what CO it terminates in.

Uhh, think you might have the wrong CLLI code. PNTCMIMN50T is
in Pontiac, Michigan and yes, it is a tandem.

Hash: SHA1

Apparently there was a software glitch in the switch(s) which disrupted
route calls.
