When power is out in my neighborhood the gray cable boxes on the phone poles switch to battery power which is good for 2 or 3 hours. After 3 hours the batteries are depleted and everything goes out. My solution is to use a home router that fails back to a cellular service Internet tethering device. Small UPS's don't run very long on battery. They are designed to run no longer than 10 - 15 minutes tops to allow for controlled shutdown of your computer equipment. I use an older Tripplite SmartPro Net 2000 VA UPS that is connected to all the computer gear including cable modem and router in my home office. It has external battery boxes that can be plugged into the UPS in parallel and extend run time. Not a cheap solution but gives me over one hour of run time for everything in the office with a single pair of 35 amp 12v batteries wired in series for 24 volts total. Adding additional battery boxes would increase run time. Usually by the 45 minute mark I switch over to running a gasoline powered generator.

My landline is wired copper back to the central office, which I know because the CO is three blocks away and I can see the wire up on the poles. The CO has a large battery bank and a generator on a trailer that they can start up when the power is out for more than an hour or so. People out in the country get their service from concentrators (often called SLCs after an old Bell model) which are battery powered. The batteries don't last forever and the plans to recharge them during an outage are spotty. R's, John ***** Moderator's Note ***** Older readers might think of a "Concentrator" as an electromechanical device - a micro crossbar exchange - which could be used to select CO lines for handling by an answering service, or as a measure to postpone maintenance on outside plant by denying dialtone to customers when no pairs were available for their calls. The Subsciber Loop Carrier system, or SLC, is called a "Slick." It is a T-Carrier system, fed either by wire or fiber, which is often installed in new apartment buildings and businesses. Although it save on outside plant costs (with either a 1-to-24 or 1-to-48 fanout, depending on options), it is not a concentrator, since all subscribers are able to use it simultaneously.

Starting Sept. 17, new telephone lines in the present 609 territory may be assigned numbers with the new 640 area code. If you already have a 609 number, that won't change, but anyone getting a new number from then on may be assigned the new area code. Adding 640 means New Jersey will now have 10 different area codes, O'Brien says. Those codes are 862, 973, 201, 551, 908, 732, 848, 856, 609 and now 640. full article at: https://www.nj.com/news/index.ssf/2018/07/if_you_have_a_609_number_saved_in_your_phone_its_n.html Presently, area code 609 has only seven digit dialing; this will end with the overlay. Interesting, because 609 covers a wide area, even a seven digit number could be a plain local call, local toll call, or cross-LATA toll call (e.g. Trenton to Atlantic City). Years ago, parts of 609 that bordered against Pennsylvania could dial only seven digits to reach border points. While today calls are still deemed local, 10 digits are required. Originally in 1947, NJ had only 201. They quickly added 609 for the southern part of the state and that lasted for many years. Notably, 201 hosted the very first dialed direct calls, from Englewood NJ.
