The reliability target on the WeCo 5ESS was/is 99.999% (the famous "five
nines"). Actually, it comes out to 99.99943% "up time". That calculates to
two hours (not seconds) of down time in 40 years.

It also requires a definition of "down time" and "up time." I recall a
line module failure on an early No 1ESS that took three days to
diagnose, then repair. 1,000 customers assigned to that module (frame)
were out of service for those three days. But, the other 20,000-plus
subscribers assigned to that switch were unaffected.

This is a story about a man, a message, a federal lawsuit and some
very unintended consequences.
James Cubbage is an Olympia businessman who came home one day last
year to this prerecorded message on his answering machine: "Hi, it's
Julie calling from Talbots with a reminder that you have only a few
days left to take advantage of your exclusive 20 percent savings pass

I don't see the (bigger) problem here. For better or worse, the
man's wife was a customer of the store, and they took advantage
of that "pre existing relationship" loophole.
So the law, in general, hasn't been vacated.
(That's not to say the law is anywhere near perfect. It's
pretty lame, and rarely enforced. I just receiver Yet Another
Robot Call from "Rachel of Account Services", a business that's
gazillions of complaints to the FTC and related regulatory
groups, and ain't nothing happening).

Another point is that cell phone rating points might have any area code,
ignoring area code geography that would be used by a telephone company
land line number. It's even possible to get 312 numbers at suburban
rating points as the cell phone companies never turned their original
pools back for re-assignment after the 312/708 split. Those of us who
went through it recall that our cell phone providers insisted on forcing
708 numbers on us even though the 312 numbers were never returned
to the pool.

Of course, and numbers tend to be reassigned quickly.

Google Voice numbers are from Bandwidth.com CLEC, a company that supplies
phone numbers to any VoIP provider. As far as I know, none of the VoIP
providers have their own number pools.
Whoa. Getting line numbers assigned automatically by a neutral third
party upon request. Too bad no one thought of this years ago before Chicago
area got 11 area codes, up from the original two. Bet we could have survived
without splits.

That's called Paypass. My Mastercard debit card here in the US has
it, but I've never used it. If my credit card had it, I would use it.

As ever, "that depends" -- does it come through with all characters
that were beyond the first 150 or so truncated away?
If so, that was SMS.
Does it come through in its entirety (except perhaps missing some
graphics components)? If so, that was probably either MMS or real
email.
My own handsets segregate inbound messages into separate IN-boxes,
one for SMS items, one for MMS items. (They don't "do" email.)
(MMS = "MultimediaMessageService", SMS = "ShortMessageService".)
In T-Mobile's service, I have yet to come up with any reliable criterion
for determining whether an email addressed to my "cellphone#@tmomail.net"
gets delivered to me as an SMS or an MMS at the handset -- I've received
emails either way, at different times, with neither rhyme nor reason
(nor even T-Mo CS) able to provide any clue as to why :-) .
I can imagine that a suitably set up Blackberry will receive an email
simply as an email.
HTH; and cheers, -- tlvp
