I don't think US phones will work.  I think there are two issues here:
there must be a billing arrangement with the foreign roamer (e.g.  an
on-line transaction system (VLR) between Chinese PTT and US mobile
carrier or perhaps the visitor could become a Chinese PTT subscriber)
and the foreign roamers phone must be compatible with the system in
use.

The system in Guangdong will be the sophisticated digital GSM (Global
System forMobile communication).  If the foreign man has a GSM phone
then he is half way there.  I don't think GSM is used in the US, yet.

No.  China uses the TACS system while the US uses AMPS.  By the way,
Motorola has around 70 cellular systems going in to China this year
alone, worth more than the Ericsson contact listed above.

There is a vendor that markets something called PhoneDisk USA (your
spelling may vary) What it is is a list of all published phone numbers
for the USA.  There is a eastern disk, western disk, business disk,
and I believe a Canada disk.  It is a subscription service and you get
new ones every so often.  (it is a CD-ROM) If you want to try one out,
outdated ones are featured in Drew Allen Kaplans wonderful catalog of
neat gizmos.  I believe it has name, number, address, and business
catagory for the business listings.  It includes a database search
engine on the disk also.

 In NYC 555-1212 is free information for out of NYC information. But
411 is not cheap!  Just to find out a local number they charge $.45
per lookup whether they find a number for you or not.

 The solution is to make a list of every possible area you may need to
get a number for and order the entire book from NYTel. I'm pretty sure
they send it for no charge. Of course it would be nicer if they sent a
CD-ROM!

   But did you then ask "YOUR number, please?", which is confusing on

   As pointed out earlier, YOUR calling habits are not typical.  There
are entire NXXs out there that might see one modem call per week.
(OK, maybe only 200 DNs are assigned to the whole NXX, but still ...)
And towns where a FAX only exists at the local service (gas) station,
for public use at cheap rates.  And these are the old switches that
are most prone to ANI failure (assuming ANI was ever installed).

   You seem to assume that ANI is available everywhere.  There are
still (very few) CDO and independents that use LEC/AT&T Operator
Services to do all the work, including identifying the calling party.
This is also needed for calls from (non-GTE anyway) eight-party lines.
While ANI failures (or mutilated ANI digits) might not be worth
saving, there are still lots of calls from stations that don't do ANI.
So the ability to do ONI is still needed.

   To complete a FAX or modem call over such lines (they are usually
not allowed on two-party or eight-party lines, for other reasons), the
modem typically provides a way for one to MANUALLY dial calls, and
force a connection (via "ato" on some), while the FAX typically allows
for the same MANUAL dialing and connection completion.  The modem

capability is also useful (thanks, Hayes) from hotel rooms where the
"bong" for calling cards is very unpredictable or where only Real
Operators(tm?)  collect the card numbers (as for some Toronto airport
coin phones).

   I wouldn't bet on Clear being the ONLY place.  There's around 1500
non-RBOC TELCOs in the continental USA, and most are just (rightly)
trying to use cheapest equipment that does the job.  Maybe that's some
old SXS CDO, or a cheap PBX-like box.  If the number of toll calls is
a few dozen/day, why put in that ANI stuff?

   Tim, I'd like more info on this SS7 "compatibility" issue.
Bellcore has certainly provided for CAMA AMI interfaces in the SSP 800
service requirements and in the LEC and IXC SS7 Interconnection
requirements.  SSP 800 also supported ONI directly, and I thought ONI
POTS calls were also covered.  The Operator Services SS7 interface
isn't well defined (yet), but that's not how I read your statement.
If you meant that Caller-ID wouldn't work with CAMA (in spite of those
that wanted it as an alternative to SS7), then I concur.

   But when you replaced the CDO in my home town, you forgot to
activate the "four-digit local calling" feature on the new switch
(grin).  And my dad's impression was that it was SWBT, not the PUC,
that forced him to private line service from 8-party.  Of course,
since the other parties all got their overhead lines replaced with
buried cable, he was (and is) the only party on the remaining pair of
overhead wires.  Kinda weird to see almost a mile of telephone poles
with one pair of wires on them (but arms for many more), and directly
below is a cable.

   Almost the same as the natural gas pipeline that runs down one side
of the road to the farm.  He doesn't own any property where the
pipeline is buried, so the gas company won't give him service.  But
his neighbors that own land on the pipeline-side of the road can get
service, even if their houses are on the opposite side of the road.
(Guess profits are better on out-of-state sales ...)

On my Pac*Bell service (5ESS) hanging up on either party in a CW
situation results in the remaining party ringing you back. This is
true on both Commstar and vanilla CW. And are you telling us that once
you have a 3W in progress, you can separate the callers and hang up on
EITHER one of your choice? My experience with 3W throughout history is
that a flash during the 3W call disconnects the third party. Does GTE
do this differently?

That is exactly the way Pac*Bell does it as well. Always has been. I
have GTD-5 service at a mountaintop location. Except for the complete
sluggishness of the switch, the features work pretty much like those
at my home. And of course, three-way calling on a GTD-5 is unusable.
The only reason I have it is because it is part of a "smart" package.
I am sure that is the only way GTE could sell 3W.

Sorry.  PacBell CW does indeed work as expected.  It is PacBell 3W
that works differently from GTE 3W.  I had gotten used to having both
work the same in GTE land, and really liked being able to "transfer" a
call from one phone to another by flashing for a 3W stutter dialtone,
then hanging up.  My phone would ring, and the caller would hear
ringback.

I recently surveyed several manufacturers of this equipment.  By far
the unit that I preferred was the SR2/SR3 by Multi-Link (606)
233-0223.  While it only recognizes a maximum of three ring patterns,
US West offers us four, I found it exceptionally reliable, and very
smart when dealing with unusual circumstances.  It also sorted out the
rings more quickly than competitors products, actually learning how
our telco sent the patterns, and adapting to the telco.  No
association with the company, other than as a satisfied customer.

ROFL!  Hey, is Ozone Boy any relation to Devo's General Boy? :-)


Funny, isn't it, that Mr. Clinton just a couple days ago promised to
help the aerospace companies.  I don't get it: clobber the airlines
with a fuel tax.  The airlines pass this on in the form of higher
prices to their customers, who will then fly less frequently.  Fewer
travelers means more airplanes parked out in the desert, and little
need for new airplanes.  Fewer new airplanes means big layoffs at DAC
and Boeing.  Did I miss something here?

Coming Up Next: Gee, the airlines are having trouble again.  I guess
we'd better re-regulate them -- it's for their own good.  Back to two
kilobuck fares for the El Lay to Noo Yawk run ...

If you look at the hardware requirements for HDTV, you'd see a computer
(Multimedia) without a:

Keyboard (input device)
Disk Drive (semi-permanent storage device)

Adding the computer part shouldn't add more than a couple hundred
using today's prices. In five years, it'll probably be a wash.  The
hope I have, if this scenario were played out, is that television
would then become an interactive media, and thus, more educational.
Presently, its "talking heads".

I live and work in the Baltimor/Washington area. I've had a sky pager
and a local Baltimore/Washington pager. The worst thing about a pager
is finding a phone to answer the page. I used to do rather critical
support of a software product. I hated the pressure I felt to respond
when the pager went off.

The skypager had a few advantages over the local pagers I have had:

1. possibilty of retrieving missed pages. (upto 100 hours ago)
2. Blocking pages. (Don't bother me I'm...)
3. future pages. (page you at some time in the future)
4. The newer sky pagers can also tell you when you are out of range.

All of these functions where accessed through a 800 number and you
PIN.  If you travel between markets (The baltimore/Washington market
includes Phily and southern New Jersey with METROMEDIA) a sky page may
be the best bet.

> Would cellular phones be better?

Having had just a pager for about five years I just recently changed
jobs and now have a portion of my cellular phone access and all
business related phone bills covered I have found the phone to be a
great asset.  I purchased a handheld phone and I also carry a beeper.
Each has it's place; there are some area the beeper does not reach and
the phone does, and the beeper battery is not dead as often as the
phone battery is.

If this is business item (you'll get remiburshed for it) get both.
Then keep the phone number to youself and be free with the pager
number.

There is a product called PCBX that does this, although they may not
have a published API.  It is made by a company in Orange County, CA,
also called PCBX.  I thin they may be in Tustin, but I don't have the
specific reference in front of me.
