                   Massive Telecom Book Arrives
                   c 1993 Vedder Wright

Bernard Aboba's "Online Users Encyclopedia" scoops the entire field
with breathtaking scope from bulletin boards to the Internet, from
how-to's to overview. This is a book for every level, beginner or
advanced. It clearly stands out from the pack in tone, organization,
and detail, offering specific information together with the big
picture -- the "vision thing."

The book is huge: about 800 pages on large format like a Sears
catalog.  The graphics and constant human touches help greatly to lead
the reader through the daunting range of technical information it
contains.

The book is for both Mac and PC platforms. Unix tips and tricks are
also found among the appendices. Other books don't attempt to tackle
this scope.

Of particular note is the detailed information for setting up SLIP and
PPP connections to the Internet, together with reviews of TCP/IP
software tools. The book contains helpful reviews of choice products,
lists of sites, software and hardware discussion, and much more. The
sections on compression utilities and file transfer are more detailed
than any other book I have found. It's well-researched and
well-organized.

Yet Aboba doesn't lose sight of the purpose of all this: to
communicate with other human beings. Vital human issues as well as the
technical details are addressed, such as the role that bulletin boards
play in relation to the Internet. Articles from online pioneers from
Tom Jennings to Vinton Cerf help to inform us of the issues at stake.

Is anyone looking for a Sony Viewdata terminal ?  It has composite
video/RGB/TTL inputs and has inputs for an external modem.  Also
included is a Prestel type facility for hooking up to a phone line.
You can access loads of places with it and maybe even Internet or your
local server.  Mail me back and I can furnish you with the model
number and more specs.  I am advertising it on behalf of a colleague
and not my organization.

Subject: Need Two to One Phone Line Switcher Help
Organization: EIES2 - NJIT

I am looking to either build or buy a device that will do the following:

I need to plug two standard phone lines into a device that will detect
which line is ringing and then connect the output to the line that is
ringing.

The device does not need to answer the call, just switch it to the
output line.  I realize two line phones and answering machines are
readily available, but that is not my application, this is just an
easier way to explain what I need.

Any replies would be appreciated to:  [e-mail]

Subject: 911 Changes in Toronto


I saw the following bizarre notice in the paper last week:

NOTICE TO THE PUBLIC
RE: 9-1-1, Auto-dial Alarm Devices

In order to provide the citizens of Metropolitan Toronto with an
effective, efficient emergency response service, the Metropolitan
Toronto ambulance, fire and police service providers utilize the 9-1-1
emergency telephone system.

Technology has recently been made available to the general public
which allows an alarm device to auto-dial the 9-1-1 emergency number
by pushing a button.  On receipt of the call by an Emergency Operator
a microphone is activated which acts as a one-way listening device for
the operator.

These alarm devices are intended to function without supervision by
automatically accessing the 9-1-1 emergency system, implying that a
need for an emergency service exists.  The subsequent one-way
transmission inhibits proper communications, resulting in unnecessary
confusion and delays, monopolizing the time and efforts of emergency
services personnel who would otherwise be serving the public in more
appropriate ways.  These calls should be received and verified by a
private sector monitoring station, where the expertise and resources
are available to manage such activity.

For these reasons, effective January 1, 1994, the Emergency Services
of Metropolitan Toronto will not respond to, or act upon any alarm
transmitted directly to the 9-1-1 system, from any auto-dial alarm
device.

Members of the public are cautioned accordingly and advised to place
no reliance on these alarm devices, which transmit an alarm directly
to the 9-1-1 system, as a means of obtaining emergency response.  Your
best access to emergency services is a personal telephone call using
the 9-1-1 emergency number or through a professionally monitored alarm
system.

Dated at Toronto this 1st day of December, 1993.

Director, Metropolitan Toronto Ambulance Service
Coordinator, Metropolitan Toronto Fire Chiefs
Chief, Metropolitan Toronto Police Force

                     --------------

Well, I can see their point, but in my humble-and-not-lawyer's opinion
they are setting themselves up for a lawsuit.  There is no technical
means to differentiate a 911 call from an alarm auto-dialer from the
case where a person manages to knock the phone off the hook, dial 911,
and perhaps mumble a few words about the emergency.

If they are really going to ignore 911 calls where the caller says
nothing, then they've thrown out half the benefit of the expensive
ANI-ALI system installed some years ago.  Now what they may have
*meant* to say is that they will ignore calls where the auto-dialer
plays a pre-recorded message, which makes reasonable sense, but it
sounds as though they've confused auto-dial burglar alarms with
personal safety dialers.

Subject: NEC NEAX 2400 Peculiarity


When I make an outside-line call on our NEC NEAX 2400 system here at
work (dialing 9 and then the local seven-digit number), the system has
the annoying habit of giving me a ring-sound (in the handset or the
speaker, depending which is turned on) and then a click that sounds
*exactly* like the far end picking up on the call. However, it is not
 -- the ring sounds then continue until the called party answers or I
hang up. What is going on that causes this initial ring-tone that I
hear followed by that click? Is it the process of the unit selecting
an outside trunk? If so, why does it give me a ring first?

It is extremely bothersome -- that click sounds so much like the
called party picking up that I am constantly reaching for the phone
handset to start the conversation (our phones have speakers but no
mikes, so we can start a call with the handset hung-up, but have to
grab it to speak when the called party answers). It doesn't matter
that I'm used to this and it happens every time -- I still can't train
myself to ignore that initial click. If these are intentional sonic
signals presented to me to indicate that the unit is working, I don't
appreciate them. I'd prefer a pause of dead silence until it grabs a
trunk and really begins the call.

There's so little correspondence between the ring sounds I hear and
the actual rings the called party's phone emits that I can't say if
that first ringing I hear is before or after the called party's phone
rings the first time. I'm guessing it is always internal-only; that
the click is when the outside connection is made.

Can anyone tell me just what is going on when I call out? When I dial
the initial "9", am I handed off to a telco trunk then, or does the
NEC just suck up all my dialled digits and only emit them to the telco
switch after I finish? Or am I "talking" to the telco switch right
after I dial the initial 9? I suspect the NEC waits until it detects a
complete and valid-by-its-standards number before it passes it to the
telco. That makes detecting and forbidding 976- and 900- calls easy.

If the NEC holds the numbers and then passes them on later, how fast
can it do this? Are the trunks it has to the telco higher-speed or
special lines, or the same as any generic business-type phone line?
Does it spit out DTMF at some far-higher-than-normal speed, or try to
emulate human-dialling speed? (It would seem there isn't all that much
time between the end of my dialling and that magical click ...)

I have no experience with other competing phone systems -- we were on
Centrex before we moved to the building which has this NEC NEAX 2400.
So do other systems do the same thing?


Regards,

Will

Subject: Unique(?) Problem With Voicemail Prompts


Someone in our firm is currently experiencing a "different" problem
with our voice mail system.  She will be leaving a message in
someone's voice mailbox and the system will interrupt her, saying "To
Send this Message, Press..."- as if she had punched a key, but she
hadn't.  The problem has been re-occurring.

Our vendor (Octel) calls it "PROMPT INTERRUPTION", and says it happens
when some individual's voice frequencies are very close to the tones
generated by the keypad.  The system interprets the voice as a key
being punched.

This seems odd, but I have HEARD of it on other systems.  Has this
happened to anyone else?  Anyone come up with a solution to this
problem?  (Other than HORMONE PILLS?)
