A tandem office is a CO primarily used as an aggregated switch point

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.

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.
