%T   "Minding Your Cyber-Manners on the Internet"

Ignoring the "smiley" books (BKSMILEY.RVW and BKSMLDCT.RVW) and one
rather generic guide to grammar, out of the hundreds of books
published so far on the subject of the Internet, this is only the
second to be devoted to the etiquette of network communications (after
Shea's "Netiquette", cf BKNTQUTT.RVW).  It is a valuable and
worthwhile
addition.

Coverage of the topic is very broad-ranging, although it is not,
perhaps,
complete.  The material is very practical, with lists of do's and
don'ts, summaries, and question-and-answer sections.  Rose has a
professional grasp of humour, and it is used extensively and
effectively throughout.

The book is not without problems.  There is a shortage of explanation
of the "why" on various topics.  There is a chapter on how flames
start (and a pretty good one) -- but not until chapter six.  Rose
recommends against the spread of "dying child" letters--but doesn't
explain the situation behind the Craig Shergold stories, nor the
related "Neiman-Marcus cookie" legend or the "FCC Modem Tax" rumours.
He mentions the frequent administrative mis-posts on mailing lists,
but not how to avoid doing them.

Some specific recommendations are questionable.  He suggests the use
of abbreviations and "cyberese" (the acronyms of common phrases, like
BTW for "by the way") as a means of keeping messages short.  This is
no longer considered good etiquette, as it is highly confusing to
newcomers -- and oldtimers as well, in certain cases.  (In fact, the
book contradicts itself at this point, recommending both for and
against abbreviations, on a single page.)  (Some may also consider the
repeated promotion of Kent's "The Complete Idiot's Guide to the
Internet" (BKIDTINT.RVW) and "The Complete Idiot's Next Step on the
Internet" (sorry, haven't seen it yet) almost to constitute "spamming"
within this book, itself.)

I definitely recommend this work for all Internet users, and
particularly
newcomers.  I very much hope future editions will extend a work well
begun.

Subject: Cellular "Auto-Registration"
Date: Mon, 20 Feb 1995 15:29:00 GMT
Organization: The Charlatan's Cabin BBS, Los Angeles CA [phone]


There has been an ongoing discussion on another network regarding
"auto-registration" in the present analog NAMPS system. It appears
that
no one on that network can give a definitive answer as to exactly how
it
works.  So I am leaving a message here hoping (knowing) that someone
will have the correct answers.

Some of the questions we have regarding auto-registration on a
cellular
phone (system) are:

1) Does the individual phone transmit it's MIN/ESN pair on powerup
after
finding an appropriate control channel?

2) If indeed the phone transmits it's ID upon powerup, why is it
apparently
ignored by some systems (AirTouch in Los Angeles)?

3) What would be the typical amount of time between auto-registration
requests on most cellular systems? (I know this varies on system
usage,
software, etc. but would like a "ballpark" number).

4) How exactly does the cellular system request an ID from each phone
and keep it orderly? (IE..does it go by ESNs? How are collisions
prevented from multiple phones? etc.)

5) How do cellular systems treat older phones (without auto-
registration)
when trying to ring them (phone call to phone)?

I'm sure I've skipped a couple of obvious questions but if someone
could enlighten me with answers to these questions, I would greatly
appreciate it.

Subject: Weird "Prime Number" and Other Messages 800 Number
Date: Mon, 20 Feb 1995 14:03:02 PST


Late one night last week, while trying to reprogram one of my own
800 numbers, I accidentally dialed [phone].

What I got was: "<sigh> The number you have reached, 6 7 7 - 4 4 4 4,
is not a working number. It's prime factors are 2 and 3,387,2222 (or
something). Thank you".

I tried it a number of times, and it kept giving me the same thing.

Today, just to convince myself that I did indeed hear that, I tried it
again, but this time got: The number you have reach, 677-4444 is not
is service ... Bucko!".

Anyhow, just another 800 forwarded to some weird destination, I guess.

After the Mitnick capture, NETCOM sent a letter to its customers.

I've excerpted a key portion of it, in which they point out that yes,
indeed, central offices -do- keep track of the CNID of incoming calls.

(Other posters in the group have suggested that typically 90 days are
kept online, just like with outgoing smdr.)

NETCOM HELPS PROTECT THE INTERNET

         - A Letter from CEO Bob Rieger to Our Customers -

I know many of you are interested in NETCOM's involvement with the
arrest of Kevin Mitnick, and how this may impact you, if at all, as a
NETCOM subscriber.  First, let me supply a chronology of events:

[lots of self abuse ^H^H^H praise deleted]

-> 8. At that point, the U.S. Justice Department subpoenaed the local
-> telephone carrier for records of dial-ins at specific times to this
-> modem. It became apparent that the telephone company's switch
equipment
-> had been compromised, so that these records could not be obtained.
-> However, the Justice Department found another method for making a
match.

9. With this information, the Justice Department knew the approximate
location of the originating call.

10. Mr. Shimomura flew to Raleigh and used cellular tracking equipment
to
locate the apartment building the calls were coming from. Eventually,
the
calls were traced to an individual apartment, and Mr. Mitnick was
arrested.

Taped earlier this week for the PBS public affairs show
"TechnoPolitics,"
the program is scheduled to begin airing nationally on Feb. 24. (It
will be broadcast in the Washington area on Saturday, Feb. 25 at 2
p.m. on WETA, Channel 26.)

Stowe said that large business customers already have a choice of
local
carriers, but that long distance companies are not interested in
serving
residential customers because the cost of their service is subsidized
by
the business users.  See the full comments, context and points of
debate

Subject: Pair Gain Line Problem, Help!
Date: Mon, 20 Feb 1995 15:49:52 -0800
Organization: California State University, Chico


I have been told by a Pac Bell (i'm in CA) tech that the reason that I
cannot connect above 9600 is because I'm on a "Pair Gain" line to the
C.O. My roommate has no problem, the tech says he's on a copper line
to the C.O.

Problem: Pac Bell refuses to change me over to a copper line, saying
that they are only required to provide a 'voice-grade' line which only
has to support transfer speed of 1200 bps (HA HA HA HA HA).

What can I do?  Does anyone have a work-around?  Has anyone
experienced
this same problem? I've tried four different modems, all with the same
problem. But if I use my roommate's line, everything works great! (For
practical reasons, I can't use his line all the time, he runs a
business
on it).

Any help would be appreciated.

We have voice mail on our phone system and wish to give the user a
choice to push "3" for a live operator.

We would like to then conference the caller on the same line with a
preprogrammed number using the telephone company's three way calling
feature and connect them to a live operator.

Is the above possible?

I was told by somebody that it is currently not possible but that
Northern was coming out with a version of Startalk Plus that would
handle this, is this rumour true?

The hardware we are using is Meridian Norstar with DR5 software and DS
cpu,
and Startalk 110.

Has anybody been successful in accomplishing the above.

Here in South Africa we experience fraudulent use of the network due
to subscription fraud (disappearances after receiving 'self inflicted'
huge phone bills), the tapping into the phone lines of innocent
victims, and other mechanisms.

Questions:

1) Do you know of similar fraud in other networks?

2) What is done to try and prevent such fraud?

3) Has any telco implemented a pre-paid residential service?

4) If so, how does it work?

[TELECOM Digest Editor's Note: Do we know of other instances of toll
fraud?  Do we?   Umm, yes, it is a very severe problem here in the
USA. What you term 'prepaid residential service' we refer to as a
'security deposit', and/or payment in advance for the first month's
charges.  Generally the telcos in the USA accept the references of
other telcos for the purpose of establishing service. If you've had
service anywhere in the USA then your credit history as far as telco
is concerned is available to other telcos for review. Of course, if
you live in one area for most of your life and have service from the
same phone company most of that time, then they have your record and
know about both your ability and willingness to pay. New subscribers
with no previous telco (somewhere) payment history are often asked to
place an amount of money in escrow or on deposit with telco to cover
the estimated billings for a month. After a year or so of good payment
history, this money is refunded with interest or placed on your
account
against your current bill, as you wish.

'Payment in advance' is *not* a security deposit, and does not draw
interest. It merely insures that your first month's bill is paid while
telco evaluates your 'typical' or 'average' use.

A third option used in some cases is called 'interim billing'.
Although
bills are tendered 12-13 times per year (most telcos bill monthly but
some bill every 28 days), in what is known as cycle billing (a group
of
different customers each day, normally 22 billing cycles per month),
for
internal use only there is the 'interim billing' which is available to
the collectors and credit representatives about two weeks after (or
before) the bill mailed to the customer. If this interim billing shows
a sudden dramatic increase in charges such as a large number of long
distance calls or calls of a great time length causing your bill to
exceed its normal balance by some large amount, then they will call
you
and ask for more money then; this depends on your status with them.

If your bill becomes past due, again your status detirmines what
action
is taken. A new subscriber with a balance two months past due will
most likely be cut. Longer subscribers with generally good credit will
be allowed longer, etc.     PAT]

I am teaching a university course on mobile communications and am

in the following data of the received signal at a cellular phone:

1. The signal envelope over time (Rayleigh/Rician)
2. The time delay response (showing delay spread).
3. The power spectrum (frequency domain)

Real measured data would be ideal, but simulated data is fine as well.
I know that I can generate it myself, but if someone else already has
the data, it's less work for me.

Subject: A Tip When Working With Electricity


Dear Pat,

   I just read about your experiences with the capacitors in a TV
unloading through you and recalled another tip which can prevent a
nasty accident. It is related to the thread because auto batteries are
part of schemes to revive NiCads. Electrocution from these may be
possible (I heard of a case but have no certainty if it really
happened),
but is quite unlikely.  Serious burns are not so uncommon.  One should
remove metal jewelery, including watch bands and rings when working
around these batteries; they can deliver huge currents, enough to spot
weld the jewelery, and heat it up to skin burning temperatures in a
second or so.

Though I have see warnings about this risk for years I did not know of
a case until a friend got it wrong a couple months ago.  He showed a
deep burn around his finger where his wedding ring combined with a
wrench to short over the battery terminals.  He was lucky; the wound
healed and except for the scar he will have gained; he knows very well
about being careful next time and may be saved from removing the
finger completely.


Sincerely,

Bob Mueller  <iff161@djukfa11>


[TELECOM Digest Editor's Note: I still have a tiny little scar on my
left
arm (on the underside, a few inches up from my wrist) which I got from
the night thirty years ago or so that I fell asleep at the
switchboard.
If you remember the old cord switchboards, you will recall the rows of
cords with plugs on the end which sat in front of you.  About 2 am
after
several slices of pizza and a quart of beer from earlier in the
evening
I was feeling drowsy. I had the common audible (buzzer) loud enough it
would wake me up, so I folded my arms in front of me as I sat there
and
put my head down on my arms ... bingo, three minutes later I am out of
it. Once before I had done this, and fell asleep with my foot on the
buzzer cut off switch; the little button on the floor the operator
could
tap on to shut the buzzer off when desired ... <grin> ... but not this
night. This night I would wake up if any calls came to the board which
was unlikely ... this was a Friday night and the Sabbath, and the
mostly
elderly Jewish residents of the South Shore Country Club Apartments
would be long tucked in their beds and asleep.

South Shore Country Club had a four position manual cordboard; usually
three operators on duty during the day and evening, and one overnight.
On Friday night and Saturday all day usually one operator was
sufficient
since the more religious of the tenants in the apartment complex did
*not*
use the telephone for any reasons those days; nor did they use the
elevator.
Instead of calling downstairs to the switchboard to get someone at the
front desk to come up and light their stove for the sabbath meal they
felt it more appropriate to walk down ten flights of stairs to make
that
request, then walk back upstairs again. Since I am not Jewish, you
see,
I was under no obligation to observe their laws; I *could* ride the
elevator
upstairs, light their stove or turn the lights on and off, etc, then
ride back downstairs.

But I digress ... roomate and I had been out earlier that evening to
celebrate something or other ... pizza and beer ... you know that
combin-
ation ... 11 pm and I have to go to work, running the board at the
Country
Club until 7 am. By 2 am everything *so* dead ... *so* quiet ... and
as noted above I fell asleep. I slept maybe three hours, and about
5:30 am
the little alarm clock goes off which means it is time to start making
the first of the 'wakeup calls' to the tenants. My arm somehow during
the night had gotten up against or on top of that row of plugs, and it
laid there most of the night. A little red burn was on my skin where
it had been on the tip of that plug all night. I thought it would
eventually
go away, and the redness went away the next day but the little scar
where
the direct current lingering in those cords burned my flesh a little
never
has.

Finally, if you ever want to test a battery to see if there is still
life
in it and you don't have a battery tester, just put the contacts from
the
battery against the bottom of your tongue ... <grin> ...   PAT]
