Subject: V&H Report January 1993
Date: 4 Jan 93 20:26:34 GMT
Organization: Moscom Corporation, Pittsford NY
Once a quarter I receive the BellCore V&H tape. Using this
information I can total the number of exchanges in each area code.
The twenty most populous area codes are listed below. After the
written text of this article I have included the count for each of the
area codes, one sorted by NPA, the other sorted (in reverse) of the
number of exchanges in a given NPA.
The tape is dated 15 January 1993. I am not responsible for the
information supplied in this tape. Yes, the date is several weeks
out. The information will be current as of that date. It is
distributed early so that it can loaded by that date.
I have not included the following in my counts of exchanges:
- NXX's that are not dialable by a standard user (ie nxx's that begin
with a 1 or 0).
- Mexican exchanges in the 52? series of area codes. I've got them,
you can dial them with 011, but they're not really NPAs.
- Exchanges that are non-dialable in the 88? series of area codes. I've
got those also, but you can't dial them, so I'm not including them.
This tape includes information for the new NPA's 909 and 210. 905 in
Toronto, and 810 in Detroit have not appeared yet.
The fields are:
------------ rank last in October, 1992
213: 736 (1, 7)
area code --^^^ ^^^ ^------- number of new exchanges
|-------------- total number of exchanges
301: 751 ( 1, 7) 416: 678 ( 6, 4) 206: 642 (11, 7) 604: 582 (20, 13)
512: 703 ( 3, 2) 919: 672 ( 8, 12) 708: 634 (14, 25) 216: 579 (19, 8)
212: 700 ( 4, 3) 215: 660 (10, 11) 713: 627 (13, 10) 503: 574 (18, 3)
313: 680 ( 7, 12) 714: 656 ( 9, 2) 703: 610 (16, 7) 803: 564 (11, xx)
205: 680 ( 5, 4) 602: 644 (12, 9) 403: 605 (15, 1) 303: 563 (11, xx)
Of the top 20 we know:
1. 301 - split in progress. Number should be reduced by split.
2. 512 - split in progress. Number should be reduced by split.
3. 212 - split in progress. Number should be reduced by split, and the
movement of the Bronx to 718.
4. 313 - split in progress. Number should be reduced by split.
6. 416 - split soon to be in progress. Number should be reduced by split.
9. 714 - split in progress. Number should be reduced by split.
Given all of that, the NPA that is largest and is not splitting nor
has plans (at this time) to split, is 205 in Alabama. Other NPAs that
are candidates for a split include eastern North Carolina (714),
Philadelphia (215), and 602 (Arizona).
The 3 smallest NPA's were and remain :
906: 117 - Michigan's Upper Peninsula (+1 new exchange)
807: 105 - Western Ontario (No change)
917: 104 - The new NYC NPA (+40 new exchanges)
A new statistic that I have added to this report is percentage growth. I have
taken the difference between the number of exchanges in January and October,
and divided by the number in January and multiplied by 100. In math notation
that would be:
((October # - January #)/January #)*100
The top ten are:
917 62.50 (Growth of new NYC NPA)
210 6.47 (Growth of new Texas NPA)
909 5.03 (Growth of new California NPA)
305 4.37 (Western Florida, rapid growth area)
708 4.10 (Chicago Suburbs, rapid growth)
704 3.42 (Western North Carolina)
312 3.41 (Chicago City)
702 3.16 (Nevada)
310 3.05 (Growth of new Los Angeles NPA)
809 2.97 (Growth of the Caribbean)
The only NPAs to be in last reports top ten and this reports top ten are:
310, 708
All the NPAs and the number of nxx's in each are listed below:
301: 751 501: 553 201: 442 502: 365 715: 321 814: 268

Subject: Worries About Privacy Could Tone Down Success of CID
From the 1/4/93 {Boston Globe}
Worries about privacy could tone down success of Caller ID
Jonathan Yenkin
Associated Press
Boston - Caller ID, a phone service touted as an electronic peephole
to let customers see who's calling, is making its way around the
country. But it may not become a ringing success because of privacy
worries.
The service, which displays the number and sometimes even the name of
the caller, is available in more than 20 states and has won praise for
deterring obscene and annoying phone calls.
But because of privacy concerns, many states have slapped on
restrictions that phone companies fear will undercut the service's
value.
"At what point does the subscriber say, 'It's not worth it anymore?' I
don't know," said Clifton Metcalf, a spokesman for Southern Bell in
North Carolina. "We're going to find out."
The restrictions imposed by utility regulators allow callers to block
their numbers from appearing on a display unit by the phone. This can
be done by pressing certain keys when making each call, or, in some
states, by having the line blocked off entirely from being decoded by
Caller ID.
After the state imposed such restrictions in Massachusetts, New
England Telephone officials found them so onerous that they initially
withdrew their plans to offer the service.
Susan Butta, a spokeswoman for New England Telephone, said executives
worried the restrictions might make the service harder to sell. They
eventually changed their minds and decided to try it.
U.S. West Communications, which serves more than a dozen states,
decided to include the blocking options in its proposals to utility
regulators, not waiting for officials to order them, said Gwen Law, a
company project manager. Consumer advocates and civil liberties
groups say such restrictions are necessary. In Pennsylvania, the
state Supreme Court ruled this year [sic] that Caller ID - without the
blocking options - violated the state wiretap law.
Critics often point to battered women or undercover police officers as
examples of people who need to keep their phone numbers secret.
"There are some people for whom the risk of forgetting to block is
very great," said Mark Cooper, research director for the Consumer
Federation of America.
But New Jersey Bell, which pioneered Caller ID in the late 1980s,
doesn't offer any blocking, and fewer than 1 percent of customers have
complained about phone numbers leaking out, said company spokesman
James W. Carrigan.
On the other hand, Carrigan said the service has helped deter nuisance
calls.
About 200,000 New Jersey Bell customers, or 4.6 percent, subscribe to
Caller ID. That compares with a 28 percent acceptance rate for Call
Waiting, which allows customers to receive more than one call at the
same time.
But Carrigan insisted customers in his state who don't have Caller ID
still benefit, "because the other people don't know whether you have
the service, so they won't make that (harassing) call."
In some places, phone companies say they are succeeding with the
service despite the restrictions.
Centel Corp. in Las Vegas, which serves southern Nevada, offers the
blocking options and still has more than 10 percent of its customers
subscribing.
Dianna Fyke, a marketing manager for Centel, said there were some
initial fears, but once people get accustomed to the service it
becomes "a matter of fact thing."

Subject: Colorado Gets Caller ID
Date: Mon, 4 Jan 93 21:23:42 MST
Caller ID is officially available in Colorado today. My wife
finally got through to the business office this evening to order it
for us, after busy signals on attempts during the day. While we are
normally served by the Loveland business office, our call ended up
being answered by the Colorado Springs business office (different area
code and LATA). The rep said that calls had been non-stop all day,
with virtually every other call involving an order for the Caller ID
service.
The best gauge of consumer opinion is how they vote with their
dollars, not with their words. If Colorado's first-day results can be
generalized to other areas, then John Higdon is quite correct that the
PUC decision in California gives the voices of a few more weight than
the desires of the majority.

I find the current discussion of CNID features on modems very
interesting. But, being in the market for a new answering machine, I
want to know if there are any which store CNID, if received, and play
it back when messages are retrieved. Or are there other techniques
available? Anybody?

I am publishing the 93 edition of Drexel University's telephone
directory. The cover artwork shows a rotary phone dial and a handset.
I would like some stories (more on the fun side than the technical
side) of the dial (when it started, how it worked, how many still
used, etc) to include in an "About the cover art" section inside the
directory.
Thanks much,
Ken

I heard an interesting theory regarding investing in the Baby Bells.
The theory was that they could be breaking up ala AT&T, and in so
doing, the parts would be much more valuable than the present whole
companies. This due to the rapidly exploding telecom revolution.
The theory sounds very reasonable to me. Any other info, data, on
this?

Subject: Voice Mail Options

With my startup moving along, I now have an office and since I can't
afford or justify a receptionist I am going to get voice mail (horrid
as it is I don't have a lot of option).
So the question is: Should I get a voice mail card for a PC (Nat Semi
has an interesting looking card that does voice/data/fax ($229 in the
local Comp USA) or do I go with the Pac Bell offering? Comments
suggestions etc, either way most welcome.
BTW If you know anybody who has 500K to invest in a software startup
let me know :-) (for the legal freaks this is not an offer to sell
securities :-)

Subject: Why Does Phone Bell 'Ping' on a Regular Basis?
Organization: University of Georgia, Athens
Date: Mon, 4 Jan 1993 19:20:49 GMT
It seems that I've seen discussion on the following topic in the
TELECOM Digest before, but I can't remember the answer or find
anything relevant in the archive index.
My parents live in Mississippi and get their local phone service from
South Central Bell. According to my parents, the bells in their
phones make a 'ping' every evening around 10:15PM. They say that the
ping almost always occurs around the same time, but that on certain
nights it may not occur until close to midnight. They've called South
Central Bell about this, and they were told that the ping was NOT
occuring due to anything that the phone company was doing.
By calling my parents number, I have not been able to find a way to
duplicate the ping myself -- I always end up creating at least one
full ring.
What is the likely cause of this ping? Is it possible that some
individual is doing it as an annoyance, or is it more likely a problem
from within the phone system?
Thank you.

Subject: Operator Breaking Cellular Connection
I was watching the movie Patriot Games this past week. In it our hero
Harrison Ford (aka Dr Ryan), on his cellular phone, asks the operator
to break into his wife's cellular phone connection. The operator
tells him this is not possible, he has to wait till she hangs up.
Although the cellular connections are not "static" like land-lines it
seems to me that SOMEONE could have broken in.
Happy New Year to all the Telecom readers.

[Moderator's Note: Most likely some person on the technical staff at
the cellular company could have done it by going in on the desired
line at the switch, but the telco operator could not do so. It is much
like asking the telco operator to cut in on a conversation between two
PBX stations. The local PBX operator is the one to ask. PAT]

Actually the PUC could order this and make it stand. The Network
Interconnect package needed to allow SS7 interconection between the
LEC and the IXC's makes provision for the calling number to be deleted
from any IAM message sent to the IXC. This is true in every central
office switch type I am aware of. This includes NTI, AT&T, and
Ericsson.
SWBT policy is that this feature is invoked in all central offices
with SS7 interconnection to IXC's until calling number delivery is
tariffed and sold in that CO and all subscribers have been fully
informed (through bill inserts, etc.) of the impacts they will see.
So the PUC could order this be done in PB-land and also require that
PB negotiate with the switch vendors to insure the capability is
retained from this day forward.
