I also have the Phonemate 9750 and am disgusted by the (lack of) design that
went into the way it handles power failures.

The machine takes $12 worth of batteries.  These batteries last one hour!

It seems to have the following reactions to a power outage:

1. If the batteries are good and there's a power glitch, everything happens
   as you would expect.  The machine acts as if nothing happened (power-wise).

2. If the batteries are hopelessly shot, or not even there, or good and you
   have a long (>one hour) power failure, then when the power comes back
   on, the machine rewinds the incoming message tape.  Yes, you noticed
   that.  It happily writes all over the messages that came in before the
   power failure.

3. If the batteries are marginal, and there's a power glitch, the machine
   puts both tapes into FF and runs them until they are banging at the end
   of the reels.  It then starts to smell like it's going to produce copious
   amounts of smoke and flame.

1 and 2 were confirmed by Phonemate's 800 number as "That's the way it
works."  3 was observed once, first-hand, and is the reason that I don't keep
any batteries in it.

While the 9750 has some nice features, it has a very low-security
touch-tone remote operation code.  Worse, I can always tell when
someone else's 9750 answers because of a distinctive answering
characteristic.

Also, the touch-tone decoder on my 9750 has drifted and had to be
re-adjusted.  I now supect that the timer that decides a caller
didn't leave a message has drifted becuase it won't save a
very short message.

I wouldn't recommend it.

I also own a PhoneMate 9750 answering machine, which I have used for the last
three years.  Its behavior over that time has been peculiar in a number of
ways.  For the first six to twelve months, the VOX circuit seemed deaf and
impatient, but that problem "healed" over time.  While it was a problem,
I just instructed the people who usually called me to speak loudly and
quickly, which got around the problem.  The other problem I have had is
DTMF deafness, but it seems to vary over time.  Sometimes it is quite
sensitive, but other times (often only a few seconds later) it's completely
deaf.  I used to think it was the telco trunks, but after MIT's cutover to
our new 5ESS (with completely new cable plant) last fall, I ruled that out.
I opened up the PhoneMate and found four trimpots on the board.  I tried
adjusting them, but it did not seem to have any effect.  I never use the
built-in handset.  In fact, I have kept always kept the PhoneMate in a
Eear plastic bag to keep it looking new and operate it through the bag.
(I use only a 1970's vintage WECO 2500 set or my 1960's vintage WECO
3B speakerphone when I want to talk on the phone.)  I've always wondered
why PhoneMate used those expensive 6V photoflash batteries for backu8f
The batteries cost ~$12, and I only paid $60 for the machine.  I overcame the
problem by wiring up an external 8 AA-cell alkaline pack.  Overall, I have
been very pleased with the PhoneMate.  Sure a few analog levels aren't quite
right, but the uP software is good, as are the front panel controls.  The
thing I like most about the PhoneMate is that it either does exactly what you
want or (if it's deaf) does nothing (and retains all messages).  I've never
lost a message with it.  I also believe Code-A-Phone makes good machines, but
not as good as they used to (e.g. Ford Industries Code-A-Phone Model 200:
the "Chrysler" of answering machines).

For some reason, people seem to delight in searching for these
numbers, when there is a much simpler solution to their problem.

When I was working in NY, I had a similar problem (multiple lines
with unknown numbers). I simply hooked up a handset to the line
and dialed the closely kept secret telephone company number, "0".
When the operator came on the line, I explained that I needed
to know the number of the phone I was calling from. She read me
the number off the TSPS console. End of story.


[Moderator's Note: That may be the end of your story, but many telecom
participants, myself included, have found that normally the operator will
NOT say what number the call is coming from. The rule is they aren't
supposed to do it, for various security reasons.  PT]

Sounds suspiciously like you have a blown ground protector.  This is a fuse
like device in the junction box, where the telco cable comes into the building.
It's purpose is to prevent excessive potential (like a lightening strike) from
entering the equipment.  Another possibility is a high ground on the cable,
this could be either inside or outside wiring.  Telco can rapidly test for a
ground and tell you if the problem is theirs or yours.  Odds are, since you
mentioned the storm, that the protection fuse has done its job and needs to be
replaced by the telco.

In NJ Bell territory, 311 produces a ring-no-answer.  I've been told
that it produces automatic number identification in a few central
offices, but I haven't heard which (anyone else in NJ know of any?).
I think most of the N10 codes are/were assigned to TWX, weren't they?

My copy of "Notes on the Intra-Lata Networks" (1984, Bellcore) lists
codes 211, 311, 511, and 711 as RESERVED.  This publication
extimates that by 1995, we will need Interchangeable NPA codes.
This refers to area codes of the NNX format, just like CO codes.
Before that time, ALL local switching systems must have been
modified to require 1+ dialing.  If anything, recent events indicate
that the 1995 estimate may be off.

I wonder how much difficulty would be caused if the USA and Canada
were to be assigned different country codes?  This would allow
re-assignment in the USA of area codes presently assigned in Canada
(and vice versa) and might push that 1995 date back a few years.

Oh yes - there was also a *big* feature in Aug 86 - the areas they measured
may give you a head start on planning a questionnaire - though the data won't
be of interest now.  Why not get more money and do the survey for them, or did

translate in the new number system.   0x1-XXX-1234     +44 x1 XXX 1234
 x=8 for "Greater London", x=7 is "City" ( 4 mile radius ).

I'm really *dreading* next Spring (junk mail) but some firms are outside

Absolutely.  We just got equal access on our business lines here and
they were switched to MCI; I reprogrammed my auto-dialer to use 10288
before all my calling card calls.   If you're placing calling card
calls from a business or residence where you don't know the carrier,
always give the 10288 (or whichever) a try.

This reminds me of something I saw a few weeks ago in Waldorf, MD
(southern Maryland - C&P territory).  On the front of a 7-11 store
along U.S. 301N was the requisite row of payphones (4).  Above the
payphones was a large white banner with blue letters proclaiming

I understood the original posting to mean that the campus had DID
trunks to extensions on-campus, but that without outgoing ANI, all the
911 service would be able to tell was that the 911 call originated on
one of the university's outgoing trunks.  With ANI from the campus, a
regular directory number would be provided with no separate extension,
much as (as you mentioned) some PBXs do for billing origination purposes.

I'd suggest not putting it on a FAX or modem line.  For quite a few
months here we were having problems with both our FAX and modem
connections being terminated randomly.  For modem use, it was obvious
that no connection ever lasted for more than an hour.  It turned out
that all the lines involved were passed through alarm systems (at
least one for intrusion and one for fire) and the systems were
"testing the lines" hourly!  We decided to get dedicated lines for
them, since, in addition to this annoyance, we didn't want an incoming
call to potentially hold up the alarm.  (They weren't ground-start
lines.)

Historically, the N10 codes were used by TWX (otherwise Telex II); whether
this is still true, I don't know.  AT&T set up TWX to compete with Telex,
and used a hitherto-empty part of its name space to avoid interference.
Later, AT&T had to sell off TWX, but the N10 codes are still treated as
sacred.  The last time I checked into the matter, which was maybe 15 years
ago, my local telco (New Jersey Bell) treated some N10 codes as "invalid
exchange" and others as "invalid area code", kind of randomly.


[Moderator's Note: But some readers have maintained, very vigorously, that
since Western Union central offices are in no way connected with or wired
through Bell central offices, their use of those numbers have no longer
any bearing on area codes. I put those codes (410-510-610-710-810-910) in
the master list of numerical area codes message run several months
ago, and finally took them out. What is the definitive answer on this? Will
someone from Bellcore or some other authoritative source please reply? PT]

The other day a friend of mine was making an AT&T operator-assisted call,
and the person she wanted to reach was not there, so she told the person
who answered the called line to have the desired person call her back at
a different number than the one she was calling from.  The problem occurred
when, after she had said "...call me back at NPA-NXX-", the operator broke
the transmitted audio path from my friend and completed the number with
"XXXX" read from her TSPS console.  Of course, the last four digits the
operator read were not the last four digits that my friend intended to say.
After I thought about this situation, I started to get upset, realizing that
there is really no recourse for my friend other than making a DDD call
and giving the person the correct number.  The operator had already hit
"position release" and was off to continue to unknowingly confuse other
customers.

Subject: Last of the area codes

I've been following the area code splits with some interest, since they
seem to be affecting just about every place I've ever lived.  As has
been noted, 909 and 917 are the only remaining "conventional" A/C's left
unused at present, and my area (Oakland/Berkeley, California) is slated
to get one in 1991, before "Time T."  Any idea what the last one will
be?  Maryland, perhaps?  Will 706 and 905 be reclaimed for use in US/
Canada, requiring "011" dialing for all calls to Mexico?

Another speculation: what areas will get new area codes in 1992 when
the telcos get to use NNX codes?  One area that comes to mind immediately
is Yukon/Northwest Territories.  For years upon years, the numerical
list of area codes in my phone book has shown "403: Alberta, 403: Yukon
Territory (Temporary), 403:Northwest Territories (Temporary), 404:
Georgia ..."  A/C 403 has been "temporary" for YT/NWT for an awfully
long time.

Subject: Other unused NPAs?

 So we are running out of area codes.  How about reclaiming the 905 & 706
 codes by breaking the North-American Zone 1 hack that uses these codes for
 Mexico in violation of the CCITT rules?  Or would this be too inconvenient?
 If we could do it, it would give a total of 4 free NPA codes (706, 905, 909,
 917).

 Is there some good reason this cannot or will not be done?

Probably quite a bit...not only would you only liberate a handful
of area codes in the process, you would disrupt important lines
of communication. We Canadians tend to phone the U.S. more than
we phone other provinces - lines of communication are north-south
rather than east-west.

LP}        Well, I just talked to our tariff folks, and 903 is not being
assigned to the Dallas suburbs ( unless you consider Tyler a suburb of
Dallas :-) According to our tariff folks, it will be the Longview lata (
544 ) and probably portions of the Houston lata ( 560 ) and the Dallas
lata ( 552 ). Geographically, I have been told it will go from Tyler
east to the state line, and south from the state line to a someplace
south of Palestine.

        As to what area codes are suitable in this area, well Fort
Worth ( the unheard of half of Dallas/Ft. Worth ) is in the 817 area
code, as well as nearly everything else west of Dallas.  Even Waco on
the south, and Denton on the north are in area code 817.  That probably
makes 917 unsuitable..  About 909, I don't know.  Maybe Southwestern
Bell made it to Bellcore before Pacific Bell. :-)

There have been several messages of late commenting on suitable area
codes, and I think this is the second time the moderator has made this
point.  As a non-insider, I would estimate that 99% of telephone users
have no preconceived notion of what an area code looks like.  It is
simply three digits.  Heck, I didn't know there were restrictions on
area code numbering until I started reading this group, and I used to
work for the phone company!

There were also previous messages about whether this area code or that
should be assigned right next to some other area code that was similar.
I don't think there is any difficulty with that from a user point of
view.  (I can't say whether there are technical reasons for avoiding
it.) After all, one seldom knows what area codes adjoin the desired one,
and if you misdial you get some wrong party -- it hardly matters if they
are 100 or 10000 miles away from the party you intended to dial.

Is there some inside reason why these points are important? I don't see
them affecting how the ordinary user sees the phone system.

Try telling the Sprint operator, "I'm calling from a pay phone and the
owner doesn't want me to use Sprint, so my keypad is turned off.  Can I
get the lower rate?"  If Sprint has *any* sense at all, they'll happily
give you the lower rate.

I could not agree more.  Even at MCI, the circut quality could even depend
on the time of day you call. Scenaro: You call from San Francisco to New
York. If you called at 9pm, your call would travel over our backbone fiber
that runs between San Francisco and Washington DC, then via digital radio
to New York (over-simplification here), but it is possible that you try at
9AM instead, and all trunks are busy on that fiber route, then we have to
find an alternate route for you call to terminate in New York. So, lets see,
we send you to Los Angeles first, then Phoenix, Arizona, then Dallas, Texas,
then St. Louis, Missouri, then......you get the picture.  Then there is
unexpected problems that can contribute, like "backhoe fade"....:-)

Ahhh yes, the local carrier lines.  I have a problem in that regard. I
am on Portal (cup.portal.com) in Cupertino, California.  I call from
Hayward, California, so, it is intralata.  I am calling from a 1AESS to
a DMS-100, distance: 25 miles.  I would hope to think that there are
directs between HYWRCA11CG0 (Hayward C.O.) and SNJSCA12CG0 (San Jose C.O.
serving Cupertino). When I call Cupertino at 2400 baud, I always get a bunch
of curly characters at the beginning of the transmission, usually
going away after repeated <cr>'s (or, during retraining/equalization).
This usually points towards frame errors/slips on a T-1 carrier, a common
problem on the DMS-100, but I have also gotten this while calling through MCI
which we have direct circuts to that C.O., but not from work, where we
route through San Francisco instead (I think it's San Francisco 10 or 12
were on).  I searched my own calls from work, and they terminate directly
into SNJS/12, but I have no way of searching my intralata calls to see
if I hit the tandem on their end (Santa Clara) or my end (Oakland), and see
if one of the tandems is screwing this up.

Of course, trying to explain all this to repair (611), and they usually
say "huh?".

Let us know if you do proceed with the modem experiments, and the results
and problems you encounter.

Steve,

Most phone calls are transmitted as a stream of digital data.  (Odd, ain't it;
the modem converts digital to analog so the central office can convert it
back to digital for transmission...)

This digital data stream passes from one network switch to another. The network
switches probably aren't synchronized to the same clock.  One switch is running
slightly faster than the other; thus the digital data stream is constantly and
steadily "slipping" as it passes from one to the other.  The scrambled bit
pattern often contains characters ~ or } or DEL (they're rich in 1-bits).

A quick workaround?  Route the call along a different path.  Using a different
LD carrier is very likely to accomplish this.

Subject:  Illinois Bell Knocked Out For Four Hours!

Service to over 40,000 Illinois Bell subscribers in the northwest suburbs
of Chicago was disrupted for about four hours Thursday because of problems
with the computer in the switching center.

Phones were either dead or inoperative for incoming and outgoing calls between
9:30 a.m. and 1:40 p.m. because of a software glitch at the central office
in Hoffman Estates, IL. Most of the disruption occurred in Hoffman Estates,
Schaumburg, Arlington Heights, Hanover Park, and Streamwood, IL.

The exact nature of the problem was not discussed by the Bell spokesman who
reported that the outage had been corrected. Apparently the backup system
which is supposed to kick in also failed.

It's not Pacific Bell, it's whoever comes out to do the work. There are
two types of installers: those that want to get the job done and those
that like to play like little Nazis. I have been involved with phone
systems ranging from 2 line key systems to multi-site PBXs and there
are as many interpretations concerning what the rules say as there are

If any repair person pulled the amphenol off any of my RJs in the

guarantee it.

On one RJ21X block in Pac*Bell land I have the following:

8       Ground Start PBX incoming trunks
4       Ground Start PBX outgoing trunks
3       Sprint Pro-Wats Lines
1       Pac*Bell Metro 800 Line
1       Ground Start DISA access Line
2       Loop Start Modem Lines
1       PBX outgoing OPX

No one, but no one has ever given me the slightest comment about this.
If anyone ever does, he will be given certain directions concerning
impossible anatomical acts he can perform on himself.

Ah yes, the bridging clips.  Here in Ithaca, the phone company installers
do "them on the left and you on the right", and twice in the last 6 months
one of those clips has popped out or shifted just enough to screw up a
connection.  Plus, would you believe it, for 4 phone lines on an internal
phone system plus a modem and fax line, I have a total of 4 of these boxes
of various sizes, plus 2 boxes of an older vintage; some installed by the
phone company, some by the phone system company.

One of these days I'm going to have to spend an afternoon and trace all the
damn wires and figure it all out.  I mean, at the current rate, if I get
another modem line I'll run out of wall space in my utility closet!

I just received a pretty, multi-colored brochure from MCI,
headlined "What a beautiful day for a revolution". The
revolution is that MCI now has "a dedicated FAX network". Is
this in the same sense that they have "dedicated customer
service", or do they really have a SEPARATE national
long-distance telephone network that exclusively carries FAX
traffic ?

It would seem to make no sense at all to maintain a dedicated
FAX network, when you already have a telephone network.

The brochures include a price list giving per-minute charges in
US mileage bands as well as internationally by country. I don't
have the MCI telephone price list hand; can I save this list and
use it as a price list for my MCI telephone calls ?
If the prices are different for phone and FAX, why ? If they are
lower than the phone prices, what's to stop me from pretending
my phone is a FAX ?

Are the implications of this outage as serious as they appear to be on

Subject:  International Reach Out Plans

Some discussion here about AT&T's Reach Out Plans recently prompted my contact
at AT&T to send me some detailed information about the three international
Reach Out Plans currently offered. As you will note, they differ from the
plan offered domestically in the United States in the time of day they are
in force, as well as how the charges are calculated.

REACH OUT UNITED KINGDOM

This plan offers 30 minutes of calling per month, for a flat rate of $22.00.
Additional half hours are also $22.00, and are pro-rated at 73 cents per
minute, which is less than the usual discount rates. Hours for calling are
1 PM to 6 PM, local time, meaning the call arrives in the UK between around
5 PM and 2 AM next day, depending on your exact time zone here. On Saturday
and Sunday, the hours are 7 AM to 6 PM both days, meaning calls can be
received there between around noon through 2 AM. There is a one time $10.00
sign up fee.


REACH OUT PHILIPPINES

This plan offers 30 minutes of calling per month, for a flat rate of $35.00
for the first half hour, and $33.50 for each additional half hour. Additional
half hours after the first are pro-rated to $1.12 per minute. Again, this
is substantially less than the normal rate or discount period rate for calls
to the Philippines. Plan hours are Monday through Friday from 2 AM to 11 AM,
meaning your call arrives there in the time frame of late afternoon through
early morning next day, depending on the originating US time zone. On weekends
the Philippines plan allows calls between 12:01 AM and 11 AM; then again
between 5 PM and midnight; and after a two hour break, can be resumed beginning
at 2 AM Monday morning. There is a $10 enrollment fee here also.


REACH OUT ISRAEL

This plan is the exception to the bulk, purchase by the half-hour plans.
Instead, there is a continuing $5 per month 'subscription charge' which
entitles you to purchase whatever time desired during plan hours at a much
less than normal or discount rate. Plan hours and rates are as follows --

Monday through Friday:  5 PM to midnight = 85 cents per minute
                        12:01 AM to 8 AM = $1.05 per minute

Saturday and Sunday:    same as above, but an additional window --
                        8 AM to 5 PM     = $1.20 per minute

There is no plan discount available 8 AM to 5 PM weekdays.


While the UK and Philippines plans do save you money once you amortize the
initial one time enrollment fee into your total charges, the Israel
plan -- which also has a $10 enrollment fee -- will only save you
money if your monthly billings are large enough to absorb the monthly
$5 subscription charge and still save money. Based on the few cents
per minute difference in the plan rates versus the least expensive economy
rates, you would need a couple hours per month of calls to Israel to make
it worth while to sign up.

Like all discount phone rates, the hours are bound to be somewhat inconvenient
for either the caller or the person called, with the exception of Saturday
and Sunday calls. And while for the UK plan, persons originating calls from
EST or CST zones would probably have the most compatibility in calling
at times convenient to the UK, the opposite is true of the Philippines plan,
where PST/MST zones would have the greatest flexibility at finding the other
end up, awake and available.

Regards Reach Out America, I've come to the conclusion that although we
in the midwest probably have the most convenient calling window based on
either direction of call other than calls straight 'up or down' within your
own time zone; the fact is we wind up paying more for calls. At 11-12 cents
a minute, calls have to be at least several hundred miles in distance before
the rates would be any higher anyway. Folks on the east, west or southern
coasts at least have the ability to make calls of greater distances.
It reminds of me of the rationale used by telemarketing companies
which locate in the middle west: we have the cheapest WATS rates of anywhere;
after all, you can only call a couple thousand miles one way, or a thousand
the other.

Anyway, to sign up for any of the three international Reach Out Plans listed
here, call AT&T at 1-800-222-0300.

The fax network is actually a non-real-time (i.e. store & forward)
fax delivery service..  It will accept your fax traffic using a fax
modem.  I don't think it will hear your voice!  By compressing a lot
of fax traffic into high-speed data packets, they can send it to a
dis-assembly system near the destination and then re-sent from a fax
modem to the recipient's fax machine.  This makes it less expensive
than voice, but not interchangeable.

Subject:  Pac Bell Gets Okay for 900 Audiotex Prefixes

Californians, not normally a prudish lot, raised so much cain with Pac Bell
and the California Public Utility Commission over the subject of 'dial-a-porn',
that the CPUC has given its blessings to Pac Bell's plan to segregate
allegedly harmful audiotex programs on the specially reserved, blockable
900-303 exchange, for which Pac Bell will *NOT* provide billing services.

The plan is intended to allow Pac Bell to disassociate itself from offensive
programming while simultaneously promoting other 900 services such as
sports scores and horoscope readings that are considered more legitimate.

Previously, Pac Bell subscribers wishing to block any audiotex programs
had to deny service to all programs. Under the new scheme, blocking will
be provided free of charge for any subscribers wishing to limit access to
the 900-303 prefix for sex lines; the 900-505 prefix for random conference
calls; or the 900-844 prefix for the more traditional recorded messages
and entertainment services.

Blocking will in fact be the *default condition* for 900-303 unless the
subscriber specifically requests having it turned on.

Under California's revised penal code, passed last year with support from
Pac Bell, 'harmful' programming is deemed as any matter which appeals to
prurient interests, represents sexual conduct which is patently offensive,
and lacks serious artistic and literary merit. As such, it closely
resembles the federal code for obscene speech.

A Pac Bell spokesman was blunt in his assessment of the matter: "Our goal
is to disconnect 'dial-a-porn'. But until/unless we have the legal authority
to do that, we've designed out 900 service to solve the problems some
consumers have had with 976.

Will this plan work? Maybe not. Several information providers, led by Sable
Commuications of Los Angeles, are challenging a federal statute for 'obscene'
and 'indecent' interstate programming which could well have a bearing
on the California law. Sable also notes they believe it is discriminatory
for Pac Bell to provide billing services for some IP's while declining to
do so for others of whom they disapprove.

The more interesting question is which 911 operator you get
when you dial 911 from a cellular phone, since the cellular
coverage areas almost always span more than one 911-service
area.

My guess is that it's just handled by the MTS operator.

In the Bay Area, the CA Highway Patrol apparently likes the help it's been
getting from drivers with cellular phones... so now *all* cellular 911 calls
go directly to the CHP. If it's not a CHP-servicable call they re-route you to
the "appropriate" authority. Oddly enough, they seemed to consider a three-car
accident I reported on US-101 ("The Bayshore Freeway") to be a "local" matter;
they transferred me to the Palo Alto police!

I don't know if they have ANI or not. They do ask for your name and cellular
number (they know it's cellular), but that may be just for prank detection.

The problem with automated operators, at least the ones I've played
around with is that after the question of whether or not they will
accept the call is asked of the called party,  the calling party can
generate the DTMF (or say "Yes" for voice recognition).  Simply
cutting off the calling party from the call is also not a good idea,
as sometimes the calling party is needed to generate additional info
or at least speak to be recognized.  Also, the voice recognition would
have to deal with foreign languages in (e.g.) heavily Spanish speaking
areas.  Anyway, this technology has a long ways to go.

Population growth...will require callers in North Georgia to

number when making long-distance calls within that area code.
Walter Sessoms, Southern Bell's vice president for Georgia,

 ...The new system would permit the use of digits reserved for

system would create about 1.5 million new numbers for 404...
Southern Bell has an application for a new area code pending,
but it will not be issued until all the new available

There is currently a total of almost 2 million access lines

This is from memory and may have changed but probably
not to much.

First of all E911 means two things:
1) an ability to route the calling number to the proper
serving PSAP. This means if one house has Police A and Fire
A and the next house has Police B and Fire A the 911 call
would go to the primary answerer (maybe police) in this
case both calls go to poilce A at the PSAP when it is
determined it is a fire call all the PSAP attendant will do is
press a button labeled fire and the call will route
correctly to the proper Fire department .

This function is now being applied to cellular as the next
author states.

Call routing should be done on serving antenna instead of
cell since it would be a finer geographcal area to define.

2) After having the ability to transmit the calling number
to the PSAP. The PSAP will then do a database lookup the
interpret the ANI DN into an address of telephone of the
calling party. This information aids in dispatch,
redialing, aiding callers who don't know their location.

It is an open item today as what to transmit to a PSAP from
a cellular phone and how much information is needed at the PSAP
- calling number? 10 digits
- serving cell?   x digits

Besides, if the DN to address translation is done at the
PSAP from their database, how could they have all the
mobile DNs from all over their area translated into their
database. (much less updated.) How would they translate roamers?

Subject: Southern Bell dialing changes in 404 area code
Organization: Digital Transmission Systems (a subsidiary of DCA), Duluth, GA


Southern Bell announced on Tuesday (5/23) that beginning October 2, all
long distance calls within the 404 area codes will require the caller to
dial the 404 after the 1 (i.e. 1-404-xxx-xxxx).  Southern Bell reports
that they are running out of central office exchages in the 404 area
becuase of an increase of 600,000 access lines (mostly in the Metro
Atlanta area).

It was reported that SB is doing this because it is a cheap, short term
solution and its a prelude to adding a new area code to the area (Metro
Atlanta will get its own area code).  Programming is in effect now that
will allow people to reprogram their auto-dialers and speed calling
numbers now.  Starting 10/2 calls will not go through and the caller
will get one of those wonderful (and usually ear-splitting loud)
recordings.

They are trying to put off the inevitable.  I understand that since I
was living in New York when they made Brooklyn, Queens, and Staten
Island area code 718.  Initially, it really can be confusing and
frustrating and I guess New York Tel. dropped a bundle in advertising.

According to "Notes on the BOC Intra-LATA Networks -- 1986", Bellcore
TR-NPL-000275...

700, 800, 900, and 610 are SACs, or Service Access Codes, which are
currently assigned.  610, as stated elsewhere, is assigned in Canada for TWX
service and is not used in the BOCs; but, as numbering assignments are
according to the North American Numbering Plan (NANP), not the US
Numbering Plan, 610 is unavailable in the US.

The other N00 codes (200-600) have been reserved for use as SACs and
will not be assigned as NPAs.

N11 codes are reserved for special functions.

N10 codes (aha, he finally gets to it) are among the remaining legally
assignable NPA codes.  As of the publication of Notes, 19 codes of the
N0/1X format were unassigned.  These included the 5 reserved for SACs,
leaving the 7 available N10 codes plus 7 N0/1N codes.  I believe the N10
codes will be the last to be assigned as NPAs.

Disclaimer: This is taken from the reference; I don't work in Numbering
Plan Administration.  As far as I know, though, the TR represents the
most recent policy (although some NPAs have been assigned since then).

I have had several occasions to use 911 from my cell phone.  On all of them I
might as well have not called.  It seems that, at least in the Metro DC area,
I always get Prince Georges County Police.  Even when I am in Virginia.  This
has caused no end of problems when I was trying to report a serious accident
on a little two lane highway that block both lanes.  I got routed to PG County
in Maryland who told me tough that I would have to get ahold of the proper VA
department, they didn't know who are even have a phone number for me to try.
Then I called the operator (a person who should know what the VA police's
number is) who ended up passing me off to PG County again.  After 20 minutes
of trying to be a good guy I gave up.  Went to a gas station and called it in
