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 tandems. > 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.

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.
