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 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. 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.
