Subject: Re: Backup Power for Cox [or other] ISP [Telecom]
My ISP is Spectrum. 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.

Do POTS lines still get power from batteries or gensets at the central
office? I gather they did "once upon a time", but is that still true?
Thanks for reading,

I agree, but even copper landlines aren't what they used to be. 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.

***** 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.

Subject: New Jersey gets new area code
excerpt from NJ.COM:
The new area code, 640, will overlay the current 609 area code
territory in the central and southeastern parts of the state from Cape
May to Trenton. 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.

Subject: Qualcomm Shouldn't Get Import Ban on Apple, Consumers
Contend
By Susan Decker
Qualcomm Inc. shouldn't be able to use a U.S. trade agency to knock
out Intel Corp. as a competitor for chips inside Apple Inc.'s
smartphones, a group of Apple consumers said in a court filing
Thursday.
Consumers in a consolidated class action lawsuit accusing Qualcomm of
antitrust violations want District Court Judge Lucy Koh in San Jose,
California, to prevent the company from pursuing any import ban that
might be imposed on Apple phones using Intel chips.
