Subject: Possible Rate Lowering by NYNEX
{Newsday} (Dec 4, 1993) had an article concerning rate cuts for New
York Telephone subscribers to the tune of nearly 297 million dollars
(US).
"If the Public Service Commission adopts the recommendation of two of
its judges, at a meeting set for Dec. 15, the cost for many New York
Telephone calls and for Touch Tone service could fall starting Jan. 1,
1994.
"A residential customer now pays $1.35 a month for each Touch Tone
line according to New York Telephone."
"The ruling illustrates the tension between NYNEX goals and regulatory
concerns. On Thursday, NYNEX announced a new marketing strategy and a
planned restructuring for its operations. NYNEX also reiterated its
determination to be able to offer a full range of interactive and
video services, including cable TV, if it can list federal regularory
restrictions."
I always knew we were being ripped off and this is one of the few
times that the PSC has come to the ratepayer's aid.
NYNEX is also setting itself up for a regulatory battle concerning
video in its service area due to a purchase of a portion of a company
(Teleport I think) which has portions of it owned by some cable
companies.

All of the telco's I deal with have billing addresses and service
addresses. The 9-1-1 Database is not (atleast in Illinois) built from
only billing addresses. We make a careful review of the database
before the system can be turned on. Any listings found without a
locatable address (i.e. P.O. Boxes, Rural Route, etc.) are contacted
and asked for their locatable address.

FX circuits are a particular headache, but not impossible to deal
with. Once they are discovered we can make specific notations on that
telephone number indicating where the actual telephone service is
located at. Special routing can be set up (if equipment allows) to
send the call to the correct PSAP (Public Safety Answering Point).

If a telephone number can make outgoing calls (even if it is a fax,
modem or remote forwarding device) then you can be that the record has
been examined for accurate service location information. If you were
to disconnect your remote forwarding device and plug in a standard
telephone (or hook up a butt set to the D-Marc) you could dial a
number just like a normal telephone line. Granted, you don't use your
line this way and there probably will never be any other outgoing
calls except those forwarded, but you *could*, if you wanted to, hook
up a phone and dial 9-1-1 from that line.
One more quick example of something we ran across. One of the local
power companies has some remote telemetry units at their sub-stations.
These units are hard wired into standard telephone lines. When we ran
across their telephone records with addresses like "SBS36L-W3" we
inquired where they were. We were told that there was no need to
address these sub-stations since "no one could *ever* make a call from
these lines". I asked to visit one of the sites with the power
company rep. I looked at it and indeed the wires come out of the
telemetry unit and go right into the D-Marc. I pulled out my butt
set, tapped into the line and produced dial tone for the rep and
dialed the time and temperature number. We immediatly went back to
his office and assigned addresses to each of their sub-stations.
I heard of a similar incident somewhere out west where a 9-1-1 center
was searching for a telephone number that had a service record showing
an address in the middle of a major bridge over a dam. After several
conversations with the folks who manage the dam, an old-timer
remembered a long time ago when they had had a telephone down in the
base of a maintenance shaft, well under the water level. Someone (I
don't know if it was a public safety official or an employee of the
water folks) went down in this shaft and someone else up on the
surface dialed the telephone number. Sure enough, there at the bottom
of the shaft, back behind some old control cabinets was a rusted old
wall phone that was ringing away. The person answered the phone and
conversed with the surface. That phone had to have an address since
it would be possible for someone to call 9-1-1 from it. I should
clarify, it had an address, but it needed a better location added to
the record.
Hope this answers a few questions, though I'm sure it will stir up a few
more comments/questions.
Happy Holidays!

I personally make the trip from D.C. to philadelphia up 95 about
three times a month. That is the first time in over a year that I
have even heard of either ship being out to sea. Speaking of which,
those ships are technically amazing. They can lay something like 20
miles of cable in a day (over a straight distance on a level sea
floor). That isn't fiber optic, so I don't know how fast that goes.

No, the "Second Avenue" central office is at Second Avenue and 13th
Street. I expect they call it that because they don't like to repeat
the number "13" if they can avoid it.
There is ISDN in the Second Avenue CO, but I would only be able to
receive incoming calls on it if I told lots of people to call a
different number than they normally do. The exchange serving me
there, which is 212-777, has no ISDN. Indeed only two out of
thirty-six exchanges in that CO support ISDN, I am told.
But another of my exchanges, the Yorktown Heights central office, has
*no* ISDN. None. Even if I change my number there.
And another central office I call frequently, 212-787 (West 73rd
Street) has *no* ISDN. None.

I am familiar with the term looping or data looping in the sense that
it relates to testing a line from here to there to see if it is
functioning properly. Some looping can also be done at various stages
with the electronics at the distant end to determine if it is
functioning properly. I do not know how this relates to fraud.

Subject: Re: PCS questions
In response to Roy Thompson's queries regarding PCS:
> what are the likely timeframes we will see for new infrastructure being
> deployed?
Given the FCC's rulemaking, and the congressional Budget Act, spectrum
auctions are supposed to occur in early May, 1994. The FCC's
rulemaking also outlines a build-out requirement that basically
requires licensees to be _offering_ service to 33% of the population
of their license area (either MTA or BTA) within five years of the
granting of the license, 67% within seven years, and 90% within ten years.
Several equipment vendors are saying they'll be rolling out equipment
in the late '94 -- early '95 time frame.
> Is there anything, other than frequency issues, that make the PCS
> infrastructure much different from standard cellular networks?
An interesting thing happened to PCS on the way to the FCC. When it
was first introduced as a concept in the industry (see Bellcore
Framework Advisory 90-1013), it was envisioned as a low-power,
pedestrian-oriented service. A typical "cell" might serve a two to
four block area, would accommodate 50-200 users, and would be designed
for low-speed (<30 mph) traffic. Such a service might someday replace
wireline voice and low-speed data service. But suddenly all sorts of
light bulbs went on and all sorts of warning flags shot up. All sorts
of players from all sorts of industries wanted to get in on this deal.
The cellular industry, perhaps thinking they could "nip this thing in
the bud", started saying, "We already do that. We ARE providing PCS.
There's nothing new here. Cellular IS PCS." Meanwhile, the FCC is
chomping at the bit to establish more competition in the cellular
marketplace. Then they hear "cellular IS PCS", and they think "Here's
the answer. Here's our competition for cellular." So, with the
Commission's underlying agenda, and the barrage of input from all the
would-be players, PCS evolved into a higher-power, wider-area concept
that looks very much like cellular.
So, in answer to your question, the main differences are that 1) PCS
will operate at a much higher frequency (with different propagation
and fading characteristics) and will require a different sort of RF
transmission hardware, 2) PCS will start out as digital radio
technology (which has it's own unique set of design considerations),
and 3) PCS will be designed from the start to take advantage of
existing and evolving Advanced Intelligent Network (AIN)
functionality, something the cellular carriers are having to try to
"retrofit".
> I suppose the micro and pico cell management will create some
> uniqueness in the network. In that case (with a pico cell for example),
> will more switches be required?
In some major cities it is possible that more than one PCS switch will
be used, but in most cases one switch will be sufficient. In most of
the schematics I've seen, the "cell site" transmitters are referred to
as base stations, and are connected to some sort of Base Station
Controller. The BSC concentrates several base stations, and from what
I can tell has enough intelligence to route calls that are local to
itself without burdening the MSS. (Of course, it still must send the
call information to the switch for administrative and billing purposes).
> What are the unique requirements for implementing at 1.8 GHz?
I'm not an RF engineer, but from what I understand the transmission
characteristics, especially fading, are much more of an issue. This
means that things like terrain, structures, and vegetation (as it
changes seasonally) have much more impact on network design.
> I understand, maybe incorrectly, that GSM uses TDMA ...
You understand correctly. Actually, many of the proponents of using
the GSM standard in the US are proposing a slightly modified version
to take into account 1) the slightly different US spectrum allocation
(utilizing more of the 1900 Mhz band) and 2) different transmission
power and propagation patterns, given that most areas of the US are
more sparsely populated than the areas of Europe where GSM has been
deployed.
> Also, as GSM becomes a defacto standard in the US, what happens to CDMA?
Although there are strong proponents of making GSM (or a modified
version) a US standard, there's no guarantee that will happen. The FCC
has stated that they would rather let the market determine standards
rather than dictate any. There are also proponents of CDMA. I've seen
some of the TDMA-CDMA dialogue in this digest. I'm not on either
"side" of the issue. From what I've read (from people not related to
any company making either type of equipment), as well as an
acquaintance at Bellcore, there is a general feeling that, as far as
capacity is concerned, when all is said and done, they're going to
come out about equal in terms of increased capacity over cellular AMPS
(approximatly 7 to 1).
> Isn't there an FCC regulation on wireless phones to support a dual-mode?
There is no such regulation, at least to my knowledge. As I stated
before, the FCC intends to let the market determine standards. In
terms of cellular, I can pretty much guarantee that whether you buy a
TDMA digital phone or a CDMA digital phone, it will be a "dual-mode"
phone in that it will have the capability to fall back to an AMPS mode
of operation (since it will be a while before digital makes any
serious inroads, and AMPS is everywhere). In terms of PCS, I don't
know that I would hold my breath waiting for a TDMA-CDMA dual-mode
phone. Maybe somebody will make one someday, but I'm guessing it will
be difficult enough to make the PCS handsets lightweight, compact, and
affordable using one technology, let alone two.
At any rate, I hope this has addressed some of your questions.

This is the second person who's asked a "help choosing cellular phone"
question. I'm going to write my choice/decision process because I
sympathize with just how painful it is to pick a phone. (I spent over
a year choosing).
It sounded like you prefer a vehicular phone. When I searched, I was
in the market for a portable -- I ended up with the Oki 900. Why? I
found that All the "hi-end" portables were the same (clarity, and tx
signal). It all boiled down to "software" features -- and the Oki (at
that time) beat everyone else hands down. 200 number Alpha-memory, 189
speed dial's, paging, online help, to name a few.
Now for vehicular, Oki has its "800" series of car phones. Many <not
all> of the 900's features are in the 800-line. The Oki 830 is the
top of the line.
Another kicker: the Cellular-1 salesman who helped me? He had an
Oki car phone and swore by it.

In Ontario canada there is a special rate for blind users. See if you

Every now and then, when I place a call from behing the PBX at my
office there is a long delay wherein nothing happens, then I get:
*click*
(Background sounds of a very noisy equipement room)
Slighly annoyed male voice: We're sorry; your call did not go
through.
*click*
It sounds so different from the usual telco breathless-woman
intercepts, that when I encounter it I always get a mental image of a
switchroom with a very harried technician, trying to fix some problem,
but constantly interrupted by misrouted calls, which he picks up,
barks at, and hangs up.
