Subject: Yet ANOTHER at&t/MI-Bell 1AESS to "Bite-the-Dust"
A notice dated today (Friday 16-April-2010) on the at&t-ILEC webpage for
scroll down to the Midwest (Ameritech) States section (IL/IN/MI/OH/WI)
AT&T Midwest is announcing that it will be making changes necessary to
collapse the existing Alcatel/Lucent 1AESS switch (BRHMMIMNCG0) located
in the Birmingham Central Office, Birmingham, MI, into the co-located
Siemens EWSD switch (BRHMMIMNDS0). NPA-NXXs 248-258, 248-433, 248-540,
248-642, 248-644, 248-645, 248-646, 248-647, 248-901 and 248-988 will
be moved from the BRHMMIMNCG0 1AESS to the BRHMMIMNDS0 EWSD."
A doc file of 'ATT20100416L.1" which has a few additional details can be
The WECO/Lucent/Alcatel 1AESS to be discontinued, BRHMMIMNCG0,
has SS7-Point-Code 250-050-068.
The existing (co-located) Nokia/Stromberg/Siemens EWSD, BRHMMIMNDS0,
which is to take-over the 248-NXX codes, loops, customers, etc. from the
retiring co-located 1AESS, has SS7-Point-Code 250-050-096. The legacy/
default (OCN:9323 at&t/SBC/Ameritech/Michigan-Bell) 248-NXX codes
already associated with BRHMMIMNDS0 Birmingham MI "Main" Stromberg-EWSD are:
Birmingham MI ratecenter: 248-203,593,594,723
Royal Oak MI ratecenter: 248-549,554
The 248 NPA split from 810 in 1996.
The 810 NPA split from the original 313 in 1993.
Does anyone know if the (originally 313-64x, presently) 248-64x c.o.code
range presently on the 1AESS (-MNCG0) had an old DIal EXchange NAme?
maybe MIchigan, MIdway, MIlton, MIssion, MItchell, NIagara, or some
other 'MI', or 'NI', or maybe 'OG', 'OH' (OHio?) ???
The existing co-located EWSD currently has 248-593 and 594, serving the
Birmingham MI ratecenter. I don't know how far back these codes exist,
but the old 313-593,594 codes (prior to any subsequent NPA splits) were
(and are) associated with the Detroit MI "Zone-6" ratecenter,
313-593 with at&t/SBC/Ameritech/Michigan-Bell's DRBRMIFBDS0
313-594 with at&t/SBC/Ameritech/Michigan-Bell's DRBRMIFBDS1
both Nortel-DMS-100, both co-located in the "Fairborn" building
(note the 'FB' in the CLLI code 7th/8th characters for the building).
The exact date of the migration of the Birmingham "Main" 1AESS c.o.codes
over to the already existing/co-located EWSD is not indicated, only that
it will take effect by the end of 2010. When I find out exact dates, I'll
post something further.
So far, there are to be FOUR existing 1As in Michigan Bell territory to
be replaced with digitals, either complete replacement with new digital
switches, or migration to existing co-located digital switches.
This leaves the following 1As still to remain in Michigan -- and also
I'm including the two remaining 1As in the Chicago IL area (Illinois Bell)
since this is all "Ameritech". However, there could still be further
announcements of replacement of these 1As before the end of 2010!
PNTCMIWSCG0 Pontiac MI
LNNGMISOCG0 Lansing MI
GDRPMIBL770 Grand Rapids MI
(the co-located GDRPMIBLDS1 Nortel-DMS-100 has some 616-23x codes,
which were known as 'BEll-x' in the 2L-5N days)
CHCGILAUCG0 Chicago IL
OKPKILOPCG1 Oak Park IL
With the exception of "Grand Rapids: 'BEll'". the other three Ameritech
1AESS offices remaining do NOT seem to have any existing co-located
Bell "digital" 5ESS, DMS, EWSD, DCO, etc. switches in their buildings.
at&t/BellSouth (Southern Bell, South Central Bell) and at&t/Southwestern Bell
both have numerous 1AESS offices (together at least 40 total) remaining.
Southwestern Bell's are mostly in the St.Louis MO metro area, as well as
scattered about Texas. BellSouth's are MOSTLY all over Florida and
Georgia (Southern Bell), but for South Central Bell: one in Nashville TN,
four in the Birmingham ALABAMA metro area, two in Shreveport LA, and
the two primary Bell c.o.switches here in Lafayette LA.
Birmingham MICHIGAN has some interesting history...
In November 1953, two years after Englewood/Teaneck NJ, Birmingham MI
became the SECOND location to have (limited) customer-originated Direct
Distance Dialing. They had customer-originated dial access to the dozen
or so metro areas scattered about the US that Englewood/Teaneck NJ already
had, as well as some additional locations -- Washington DC (202),
Baltimore MD (301), and New Haven CT (203), the latter in CT being a
SxS city, while Washington DC Metro and Baltimore MD were Panel/#1XB and
probably now some #5XB. Apparently both Washington DC and Baltimore MD
had completed their conversions from 2L-4N to 2L-5N by late 1953, since
CUSTOMERS in Birmingham MI were now able to place dial calls to these
locations. Washington DC did their conversions in several staged phases,
while Baltimore MD did their conversion in a single city-wide cutover.
I assume that Englewood/Teaneck NJ now had originating customer-DDD
access to these three locations as well by late 1953. I do NOT know if
San Francisco/westbay/north-of-Golden-Gate CA was still uniquely
indicated with 318 (while Oakland and eastbay CA was separately indicated
by 415), or if the entire San Francisco/Oakland CA Bay Area was together
referenced with 415 "only", by late 1953. Birmingham MI is a suburb of
the Detroit MI metro area, and would have already been part of a "7D"
(straight 2L-5N) metro message-unit or short-haul toll dialing area, so
the use of 313+ before the 2L-5N numbers would NOT have been dialed back
then for any customer-dial calls to Detroit MI and other suburbs, from
Birmingham MI back then.

Subject: A question for the readers [nfp]
Since Usenet traffic has been declining, I'm curious if the readership
would be interested in having the Telecom Digest available from Yahoo
I've created the TelecomDigest group on Yahoo Groups, and I'm thinking
of using it to "gateway" messages from Yahoo users into the
Digest. Please let me know if you think this is a good idea.

Subject: The Truth May Be Out There, But ...
I just looked up and realized that it's 12:30 in the morning and if I
don't get some sleep I'll be dead tomorrow. I just had to write this
I've just spend about four hours going from one video to another on
You Tube, and I can't even remember why I went to the site in the
first place, or what I saw there that led to where I wound up.
There was a guy from New Hampshire who was jailed for having a couch
in his yard.
There was an ex-marine who was trying to tell me that the best thin to
do after the apocalypse was to start up a generator at a hospital so I
can charge a battery to get a diesel car started, and how I could make
diesel fuel by boiling fat out of a grease trap and get around in the
city by using the sewers.
There was another guy who told me what an idiot the ex-marine is for
trying to make people believe what he put on tape: I had noted some
"huh?" moments myself, such as the idea that a cab company would have
a CB transceiver hanging around, or that CB and Amateur operators are
the same thing, so I tended to agree with the other guy.
There were several other home videos of people railing against the
Income Tax, or the Social Security Tax, or whatever else they were hot
about. One guy was talking about Hitler and the Holocaust and asking
his viewer, again and again and again, at what point they would act if
it started up again.
After that, there came a rash of links showing something about
"Kinetic Typography", with several Hitler speeches thrown in as
examples, although the typography was in English, go figure. I hit the
"Back" button until I could get back to the survivalist and his
critics, and, as I said, all of a sudden it's almost One A.M.
Well, everyone gets to take their soapbox to the town commons. I'm
just surprised, somehow, that so many people feel the need to tell
everyone else how soon they think the sky will fall.

Subject: Physical reason why humans can't drive holding a cellphone and talk
The ol' "can't walk, talk and chew gum at the same time" adage
seems to have a basis in reality". I found this article earlier
" For those who find it tough to juggle more than a couple things
" at once, don't despair. The brain is set up to manage two tasks,
" but not more, a new study suggests.
" That's because, when faced with two tasks, a part of the brain
" known as the medial prefrontal cortex (MFC) divides so that half
" of the region focuses on one task and the other half on the other
" task. This division of labor allows a person to keep track of two
" tasks pretty readily, but if you throw in a third, things get a
" bit muddled.
" "What really the results show is that we can readily divide
" tasking. We can cook, and at the same time talk on the phone, and
" switch back and forth between these two activities," said study
" researcher Etienne Koechlin of the Université Pierre et Marie
" Curie in Paris, France. "However, we cannot multitask with more
" than two tasks."
" The results will be published this week in the journal Science.
" Essentially, the brain behaved "as if each frontal lobe was
" pursuing its own goal," Koechlin said.
" subjects perform as if they systematically forget one of the
" three tasks," Koechlin told LiveScience.

Subject: Web Coupons Know Lots About You, and They Tell
Web Coupons Know Lots About You, and They Tell
By STEPHANIE CLIFFORD
April 16, 2010
For decades, shoppers have taken advantage of coupons. Now, the
coupons are taking advantage of the shoppers.
A new breed of coupon, printed from the Internet or sent to mobile
phones, is packed with information about the customer who uses it.
While the coupons look standard, their bar codes can be loaded with a
startling amount of data, including identification about the
customer, Internet address, Facebook page information and even the
search terms the customer used to find the coupon in the first place.
And all that information follows that customer into the mall. For
example, if a man walks into a Filene's Basement to buy a suit for
his wedding and shows a coupon he retrieved online, the company's
marketing agency can figure out whether he used the search terms
"Hugo Boss suit" or "discount wedding clothes" to research his
purchase (just don't tell his fiancée).
Coupons from the Internet are the fastest-growing part of the coupon
world - their redemption increased 263 percent to about 50 million
coupons in 2009, according to the coupon-processing company Inmar.
Using coupons to link Internet behavior with in-store shopping lets
retailers figure out which ad slogans or online product promotions
work best, how long someone waits between searching and shopping,
even what offers a shopper will respond to or ignore.
The coupons can, in some cases, be tracked not just to an anonymous
shopper but to an identifiable person: a retailer could know that Amy
Smith printed a 15 percent-off coupon after searching for appliance
discounts at Ebates.com on Friday at 1:30 p.m. and redeemed it later
that afternoon at the store.

Subject: Amazon ignoring VoIP attacks from within its "cloud"
Irresponsible behavior on Amazon's part.
" Complaints of rampant SIP Brute Force Attacks coming from
" servers with Amazon EC2 IP Addresses cause many admins to
" simply drop all Amazon EC2 traffic. Generally, SIP brute
" force attacks attempt to register various peer names to a
" system and/or attempt to guess passwords of known/guesses
" peers or endpoints.
Article continues here:
" The complaints mentioned this weekend show an excessive
" amount of traffic; with some providers claiming 6GB of
" traffic dedicated to such attacks. Since we ourselves
" received an attack from an Amazon hosted server, we also
" reported and complained to the Amazon NOC/Abuse depts.
" There are various techniques to assist with minimizing
" DDoS and Brute Force attacks, such as limiting access
" via the public internet, using strong passwords, not
" mapping extension name to peer/endpoint name, limiting
" simultaneous calls, and aggressively monitoring usage.
" Automatic blocking of abusive IP's (fail2ban, blockhosts,
" etc.) can also assist with minimizing damage.
