The two major distinctions between narrowband and broadband PCS are
(1) the amount of spectrum allocated to each, and (2) the particular
frequency band allocated to each.  Narrowband PCS resides in the 900
MHz band and is constituted of 26 different channels ranging from as
little as 50 kHz unpaired channels to as much as two 50 kHz channel
pairs.  Broadband PCS resides in the 2 GHz band (actually, fixed
microwave users reside there now and will have to be moved by the PCS
licensees -- but that's a whole other story) and is constituted of
either a 30 MHz allocation per license or a 10 MHz allocation per
license.

You can think of Narrowband PCS as the next, more advanced, generation
of paging services, and Broadband PCS as the next generation of
cellular service.  I say that knowing that I may get flamed (because
it is an inaccurate, oversimplification), but it is nonetheless a good
way for the uninitiated to get his or her brain around the concepts.

Depending on the particular frequency block, licenses are awarded for
different geographic areas: Nationwide, Regional, MTA, and BTA.  MTAs
and BTAs are market areas devised by the Commission based on Rand
McNally Marjor Trading Areas and Basic Trading Areas.  A BTA is made
up of a group of counties.  There are 493 BTAs which, together,
include all of the United States and its territories.  MTAs are
collections of BTAs and are much, much larger.  There are 51 MTAs
covering the entire country.  Finally, there are six narrowaband PCS
regions, each region being a collection of MTAs.

If you want to get more detail on the geographic definition of each
PCS market area, I recommend to you a file in my anonymous ftp
directory:

 ftp://ftp.clark.net/pub/rjk/pcs_mkts.txt.Z

The compressed archive includes a very large text file containing a
data compilation, made available on a shareware-like basis, providing
a county-by-county breakout (with 1990 and 1980 population data) for
each PCS Region, MTA, and BTA, as well as each cellular MSA/RSA.  If
the shareware fee is paid, I send out a disk that includes the same
data in *.dbf, *.xls, and *.csv format so it can be imported into your
favorite database or spreadsheet program and sorted, number-crunched,
manipulated, etc.  This data allows one to see precisely which areas
are included in each PCS and/or cellular market as well as to perform
calculations to determine the extent of overlap between cellular and
PCS markets.

The table below shows the frequencies allocated for Narroband PCS
channels 1 through 26 and Broadband PCS Blocks A through F, as well as
the geographic basis on which each license will be awareded.  The
channels marked with an asterisk are those for which special credits
are awareded to "designated entities" in any auction for the licenses.
Designated entities are small businesses, women or minority owned
businesses, and rural telephne companies.  The special benefits
availalbe to one or more of these, depending on the particular
license, may include bidding credits (in effect, a discount off the
amount of the winning bid), favorable installment payment provisions,
and (in the case of the rural telephone companies) the right to
subdivide geographic markets.

is already underway, and the regional licenses will be issued shortly.
The acution for the MTA-based Broadband PCS licenses (Blocks A and B)
is currently underway, with the auction for Block C scheduled to begin
in April (or 30 days after conclusion of the current auction).
Auctions for the remaining Broadband blocks and for the MTA and BTA
Narrowband channels have not yet been scheduled.

I received a letter offering a long distance service from a company
called "Dial & Save." This offered savings relative to special plans
from ATT, MCI, and Sprint by simply dialing their special access code
before the area code. The billing shows up on your regular monthly
bill. I called their 800 number (1-800-787-3333) and their rates for
some calls seem good.  Are they legit and has anyone had experience
with them?  Any problems? I was thinking of testing it bytrying their
service for a couple of calls and seeing what shows up on the monthly
bill.

Subject: Re: Bellcore Standards Question


Sorry, but I lost the original message so no quotes here.

 From the ANSI side of the house, T1.403 (DS1 Standard) does not
really define an IDLE code.

ANS T1.408 (PRI Layer 1 Standard) defines the Idle code in a B-channel
or H-channel as a "...pattern including at least 3 binary ones in an
octet..." that must be transmitted "...on every time slot that is not
assigned to a channel (e.g., time slots awaiting channel assignment on
a per-call basis, residual slots on an interface that is not fully
provisioned, etc.)..." (from Section 6.5 of ANS T1.408-1990).  Just
for further information, the idle pattern for the D-channel is HDLC
flags, NOT all 1's as in the BRI.

Note that this means that the B/H-channel idle code from the network
could be the HDLC flag pattern, since it satisfies the requirements.
That is why detection of HDLC flags on a PRI channel does not
necessarily mean that the channel is connected.

Other facts about T1: If you transmit inverted HDLC in every channel
across a T1 span using Super Frame you have a 75% chance of emulating
Yellow Alarm when transmitting flags.  If the HDLC is aligned with the
frame structure, the chance goes to 100%.

Hmmmm ...

How will this affect the Cell One/NY (00025) market where sections of
the Connecticut (00119) market and ComCast/NJ market are considered
"home" rates, even for toll calls?

Currently, CO/NY customers can roam into sections of the CT or
southern NJ systems and pay only "local" charges when calling a number
from these areas. They are also not billed toll charges for the
automatic call delivery toll component.

Will any of this change as a result of the AT&T acquisition?

Also, will redirects to voicemail (eg, if, when roaming, you don't
answer your phone and a call goes back to voicemail) be affected in
any way?  They don't work in many NACN markets, but will voicemail
redirects continue where they are currently offered?

I know for sure that Cable & Wireless is passing ANI (not CID) to many
areas, and is doing so via Caller ID.

This is a really nice feature, yet they panic when you talk to them
about it, and deny it exists, etc.

It doesn't work from everywhere. For example, I was in LA a while
back, and it never worked from area code 909, but it worked fine from
213, 818, 310, and 714. (No, there is no Caller ID in CA, I called to
Boston and had my computer page the number back to me on my pager ...
awful hack; it would be very nice if there were Caller ID already in
CA!)

It also doesn't work to everywhere: I made a call from a payphone in
Concord, CA recently. I called to Boston, and it ID'ed fine, yet
calling from the same payphone to the saem C&W 800 number to a number
in Connecticut, I got "Out of Area". This is pretty consistent. It
seems to vary from local telco to local telco, and from LATA (or area
code?) to LATA.

Finally, it also isn't reliable: I can call from Vancouver, BC, and
usually get the ID, but about 30% of the time it just gets "Out of
Area". Some areas work more reliably than others, such as Vermont to
Boston, yet others, such as NYC to Boston are very unreliable.

Hmmm ... I've NEVER received Caller ID info on ANY AT&T call, so
unless they are doing something different with their 800 service I
doubt it. I know the minute you mention Caller ID/ANI to Cable & 
Wireless, 
they say "Oh, call your local telephone company about that, we don't
offer that."  (Which is foolish -- it's an excellent selling point. If
I worked for C&W I'd be actively trying to overcome whatever technical
difficulties which are preventing universal ANI->CID display and then
really go out and market the service!)

Subject: Dial Modifiers and International Callback Service?
Organization: SHAPE Technical Centre, NL
Date: Wed, 18 Jan 1995 11:09:00 GMT


Problems:

I subscribe to an international callback service to get lower rates
from the US to Europe. I need to fax and data connect to US numbers
vai my modem.  I dial a US number, let it ring once, hang up, get
called back and upon answering have a US dial tone.

I would like to automate this process using dialing modifiers for both
faxing and modem connections. If I do the callback part manually
including picking up the phone and then initiating the modem or fax
dial command I often time out on the callback connection (while the
fax is being prepared) since dailtone inactivity of ~20 seconds causes
my callback connection to terminate.

My timeout problem is with the callback service (if no activity takes
place once dial tone is established after ~20 seconds it disconnects
so - "Changing the S-Register S7" or other modem characteristics will
not have any affect.

I thought that some combination of "," "!", and "W" as part of the
dialing sequence might give me what I need but I have no experience
with these. I am not sure what "!" does - does it toggle the hang up
button or does it disconnect? I need to hang up after signaling (one
ring) for the US callback service to call me. I then need to answer
the phone (I can due this manually if need be), and then dial the true
number. If "!" hangs up and then reconnects to a dial tone I will not
be called back (reciever is off the hook). How do I hang up - can I
issue a +++ATH in the dial string?



Example ATDT00-1-123-456-7890, ! W 1-555-555-5555
        ^                    ^ ^ ^ ^Dial US phone number
        |Dial callback       | | | Wait for dial tone (manually 
answer)
                             | | Hang up (is this true?)
                             |Wait for X seconds to ring once

Does any one have experience with this? Please reply via mail. Thanks.

I'm looking for a PBX/Fax back/voice mail system that would do the
following:

Connect to approx 4 POTS lines for incoming calls and have various
facilities when you call in, for example:

    press 1 for a recording discussing our services
    press 2 to leave a message
    press 3 to enter your fax number for a faxback
    press 4 to ring someone's extension
    press 5 for a receptionist

The more flexible and programmable, the better.

Any ideas where to look and what I might have to pay?

 BellSouth (Southern Bell) provides this service in Atlanta and
Savannah area NOW. Customer can see telephone number (Caller ID) or
name and number (Caller Id Deluxe) of a calling party or that of a
call waiting (Call Waiting Deluxe). If you subscribe Caller Id Deluxe
and Call Waiting Deluxe service, you will be able to see number and
name of calling party and waiting party.

ADSI: Analog Display Services Interface.

 Customer needs to have equipment which supports ADSI interface
(like NT phone describe above) and just the POTS line (no ISDN
necessary).

 Deployment of this service in Alabama and Tennessee is
expected during 1995.

Subject: Freephone Forum vs. ITU Question 


Someone (sorry don't remember who) had posted:

> This is the first I've heard of the "Freephone Forum."  I always
> thought call processing recommendations were issued by the 
International 
> Telecommunications Union (ITU).

As explained to me, call processing recommendations are still done by
the ITU but many perceive the ITU as too slow so other agreements are
made in other forums and implemented on "bilateral agreement" basis.
The Freephone Forum is one of them.  The fourm is made up of (mostly)
marketing people from all the service providers who provide toll free
in their countries.  They discuss freephone and how to get more people
to use it, and share success stories etc.  They also, (like most
marketing groups) seem to "party" at these once a year things.

One of the things they did develop is "Plus Freephone".  That is a 
bilateral
agreement that if you make an international call to an other countries
800 number, (eg if you dial from London, 00 (their international
calling access) followed by 1 (the US country code), followed by 800
FLOWERS) ) the call will complete to 1-800-flowers in the US.  Also
the originating party (London) will suppress the billing to the caller
and create a billing record to charge to 1-800-flowers.  If this
agreement is in place between two countries 800 calls are possible to
the US and calling freephone numbers in other countries is possible.
If this agreement is not in place, then then (in this case, London)
would recognize 1 as USA and reject the call when it saw 800 because
this is not a valid NPA code.  (Remember, per the ITU all switches
must screen on 4 digits before routing.)  1-800 is invalid.  1-405
would route to maybe miami and 1-212 would route to NY.  1-213 (los
angeles) would probably route to NY or Maine.

The people who attend the forum are often the marketing manager or
service manager for the 800 (or freephone service) in their country.

I will address the phone pad question shortly.  (A good question - the
answer may surprise you.)

But a question asked on another list raised a good point.

Because the International Freephone numbers, and domestic freephone
numbers, will *co-exist* in the U.S., the U.S. Users Group has valid
concerns that there will be confusion among U.S. consumers.

More to come.
