Subject: The IIA "Free" Internet Account
Organization: Tansin A. Darcos & Company, Silver Spring, MD USA


Awhile back there was talk here of a "free" account from the IIA
(International Internet Association).  One of the comments was that
they required a credit card for people outside the local area who
might use their 800 number so the company could bill them at 25c a
minute.

I personally coined the term for this: "The Nevada Plan".  That's
where a company provides a service in which they pay for the service
via charges based on telephone calls into the service.  A talk line in
Nevada started this in which you dialed a specific 702 number and were
connected.  The kicker was that you had to call long distance via
AT&T.  AT&T gave them the 2c/minute fee for the connection.

At least one other company has ticked off a similar deal with Sprint
and with MCI for another service.

For those of you going to one of the various convetions who would like
to be able to contact your home computer, there is already a full
internet service which is accessible as real "Nevada Plan" service --
all it costs is a call over AT&T to the provider's number -- and
doesn't have additional charges larded onto it the way this 800 number
thingy does.  (They assess the charges via the credit card supplied to
them.)

The service is called Speedway, and the number -- which has to be
called via AT&T -- is (10288) 1-503-520-2222.  I have no connection
with that company other than as someone who has used their service.

The provider of speedway offers shell access to a Unix system, and
includes full internet connectivity, including E-Mail, almost all
national newsgroups, and the usual internet tools including whois,
ping, nslookup, etc. The company also offers slip connections, and
will act as a DNS receiver for DNS forwarded mail for those wanting
their own domain name.  All at no cost above the AT&T 12c a minute
rates at night or higher during days.

At my own request, they have added a gateway for outgoing SMTP mail,
which is accessed via the command SMTP at the login: prompt.  This is
quite useful for a system that has an incoming mail gateway that wants
a means to post mail which is possibly less expensive.

Since the rate per minute is whatever AT&T charges -- which is
probably less than 25c a minute except during daylight prime time and
may be less if you have a calling plan -- this option is a suitable
alternative to using IIAs overpriced "free" service (unless you happen
to be in the local area of their service).

There is a file called the Public Dialup Internet List (PDIAL) that
lists Internet service providers, the local calling areas each serves,
the services they offer and outlines their rates.  It lists many
providers in North America and a few that are eleswhere in the world.
Look for PDIAL015.ZIP on a local BBS.

A good source is Susan Estrada's "Connecting to the Internet",
O'Reilly, ISBN 1-56592-061-9.  It describes the various ways to hook
up, pros and cons, and has a lot of providers listed, in the U.S.,
Canada, and elsewhere.

For a general introduction to the Internet, including a fair amount of
discussion of how you hook up using a PC or a Mac, try "The Internet
for Dummies", IDG Books, ISDN 1-56884-024-1.  I think it's one of the
most superb books ever written in the English language, but since I
wrote it, I may be biased.

I would like to increase the range of my cordless phone. Does anyone
know if there is an easy way to do this? i.e. clip/screw a few
resistors ...

Would it be possible to put a linear amp on the base? Could you also
increase the gain of the base antenna?

Any suggestions welcome.

BTW: Im only interested in the technical aspects of doing this.

[TELECOM Digest Editor's Note: Remember that whatever you do, you also
need to increase th handset's range accordingly. It is pointless to have
the base be able to talk for a mile if the handset is not strong enough
to get back to it. Remember also that the more distance you are able to
cover with your cordless, the more others will be able to get back to
your dialtone also, especially if you have an older style cordless.  PAT]

The newsgroup is named alt.snail-mail, and has had some lively

the messages deal with the U.S. Postal Service, but private courier
companies and the postal administrations of other countries have also
been discussed.

Or perhaps BRI ISDN on one of the pairs and normal loop-start on the

Or perhaps BRI ISDN twice -- once on each of two pairs.

     As a data point ... the systems here currently have 12 data
lines.  All but one (our ISDN line for IP connectivity) are analog
lines, and cost $8.50/mo.  ($3 of that for undesired "network access
for interstate calling" which I'm told I can't skip), since they're
measured rate, which makes sense for our purposes since they're dialin
only.  Pac Bell just pulls another five-pair cable each time we run
out, and wires it up to another six-position network interface, which
now are arranged in a nice row along the outside of the house.

     When we had used up the third set of lines (we have five voice
lines too), I expected them to pull out the five-pair cables and
replace them with a 25-pair cable, but they somehow managed to get not
just one but (for a change) two more five-pair cables through the
conduit.  I doubt we'll need more than 25 pairs, so I don't get to see
what they'd do next :)

     The data lines are connected to a motley assortment of modems
which are on multiport boards.

Speaking about adding a digit, is there any plan in the USA to add a
digit when the system runs out of valid area codes? Or will they buy
time by changing the N0X N1X requirement?

THe telco SHOULD get paid for the value of its service -- via the

In the last couple of years, I have been using various such devices,
ranging from simple ringdown boxes to small PBXes, for exactly this
application. I have found a great variety in the quality of these
units.  Here are some issues:

(1) Some ringdown boxes burn out, if they have to supply dial tone to
    both sides at once. I experienced this problem with some very
    inexpensive (USD 106 at Graybar!!) ringdowns. That made them
    unusable for my purpose, but they would work fine for one-way
    ringdown applications, and could indeed be strapped for one-way.

(2) The TelTone TLS-3, considered by my colleagues in the voice-mail
    industry to be the Cadillac of line simulators has shown many
    problems on my bench: Weak ring signals (won't reliably trigger my
    ZyXEL modems), lots of glare (because it is slow to recognize a
    hangup; like many Centrex lines I have seen). This can sometimes
    be a nuisance when stress testing two-way dial-on-demand routers.
    (I wonder how the Proctor units compare in this respect.)

(3) The Panasonics KX-T308 and 616 series have been great for this
    application, but they have a limited number of talk paths. For
    example, the 308 allows four simultaneous calls, the 616 allows
    8, I think. So if you are using any trunk side connections, you
    may experience blocking on local calls. This is not well
    documented. (Actually, I think you can have blocking even if you
    don't have trunkside connections. I've moved away from the lab
    with the KX-T's - anyone care to test and report ?)

[TELECOM Digest Editor's Note: The 'New York pager scam' involved this
guy who took out a very expensive (to call) phone line on the 540 (?)
exchange in New York City. That exchange *only when calling from the
LATA (212/708/914/516?)* charges the callers in the same way that 900
or 976 service works elsewhere. This guy had a line which cost the calling
party something like $20-30 each time they dialed it and he sent page
messages to (apparently) thousands of pagers in the area asking them
to call him back on his expensive number ... they responded by the
thousands and he got a nice commission from telco -- just like you
would get if you ran a 900/976 service. The people who called got very
large charges on their phone bill, and the guy made a mint from it.  PAT]

NYNEX has created a new area code 917 for pager, cellular, and
"certain other services", in addition to their 212 and 718 numbers.
In an area where almost every tall office building has at least one
PBX with direct-dial extensions, NYC is a pure example of the
so-called "phone number shortage" myth.  They just keep adding NPA's.
If someone can explain how there could possibly be a phone number
shortage, especially with the elimination of both 1 + 7D and the
recent expansion of area code second-digit assignments please send me
E-mail or post here to the Digest.  I have always believed this to be
an urban legend, especially in light of the elimination of 1 + 7D in
the past ten years and the more recent second-digit area code allowance.

Back to the original thought of the post, I always thought that the
only pay exchanges in all of the NYC area codes was 976.  This has
nothing to do with 1-900, by the way.

By the way, I don't see area code 708 in NYC.  You probably meant 718
(Queens/Bronx/Bkln).

This is a problem, and is going to be more and more prevalent as the
years go on.  Indeed how can a telephone customer protect himself/herself?
Here in no particular order are a few thoughts.

1.  If you get ISDN you will virtually eliminate this problem.  The
ne'er-do-wells who tap onto phone lines these days use very
inexpensive conventional telephone equipment in their efforts, and
cannot accomplish anything with an ISDN line (other than generating
synch errors).  It will be many years (perhaps a decade) before
equipment to permit seamlessly connecting to an ISDN line becomes
commonly available.

2.  Before moving into a premises, do a security survey of the
incoming utilities.  Ideally the cable from telco passes underground,
directly into your building.  Ideally within your building the cable
then goes straight to a room that nobody gets into without a key
(ideally your key).  Etc. Etc.

3.  One bad situation is if your building is multi-tenant, and if the
telephone wiring is in places that lots of people can get at (some
public hallway in the basement, say).

4.  Another bad situation is if there is a connection box outdoors,
where anybody can get at it, with your non-ISDN dial tone ripe for the
plucking.  It is probably "locked" with a hex bolt that can only be
"unlocked" by people who have such rare tools as socket wrenches.

The key is to think about this *before* you move in.  It is generally
impossible to get the telephone company interested in the situation
once you are there.  "Yes, New Jersey Bell, that is *exactly* what I
want you to do!  Now get out here with that backhoe and put that line
underground right now!"

It is also generally impossible to get a landlord to do anything about
this *after* you move in.
