Subject: Phone/FAX/Data Calls (Summary/On-Site Experience)
Long time ago (no, this is not an adventure :-) I asked some questions
here in the TELECOM Digest about getting my telephone connected in a
way that would make it possible for me to receive FAX and data calls,
unattended.
I got some answers with the most useful (for me) being from Stuart
Whitmore (whitmore@tahoma.cwu.edu) about a share ware program called
BGFAX, now v.1.21, made by B.J. Guillot (st1R8@jetson.uh.edu),
anonymous FTP://csn.org/Computech
Being just a private hobby among several it took me a while to put it
together, but I promised to post a summary if I got something useful
and that is what I am doing now. As I have also been succesful in
setting it up to work with redirection of incomming phone calls to an
answering machine, if that is what the caller want, it may also be of
some use for those with interest in such matters.
My PC is an IBM Notebook (Japanese model) with a plain vanilla
V.22bis/V.42bis MNP4-5 FAX/modem. To effectively split voice from
FAX/data I bought a FAX- switch from JDR Microdevices of $90 USD. They
also have a smaller version at $60 USD, which should work as well. The
only difference being an extra connection for a modem, which will be
useful if you have FAX and modem on different machines (not
interesting in this case). The "effective split" is dealt with this
way because I don't know of any special functions implemented in the
(high-tech?) Japanese telephone network, e.g. distinctive ring, ANI,
CID, etc. that seems to be available anywhere else?! So, if this
works in Japan it should work in most other countries.
The JDR Microdevices FAX-Switch can be programmed to redirect the call
upon detection of certain DTMF tones upon connection. If no tones are
heard, e.g. a FAX CNG tone, for a period of four seconds it assumes
it is a telephone call and connects the phone. My phone has the
answering machine built in (like about 90% of all phones in Japan),
but there is a connector for a stand alone answe- ring machine. This
means that a normal telephone caller only hear a different ring after
connection, until I or the answering machine answers the phone. A FAX
will also go through with no special action, unless the caller has an
old FAX machine that doesn't transmit a CNG tone. However, the data
caller has to add a pause (a few commas) and then the code for the
modem redirection.
Having come so far BGFAX takes over, to decide whether the incomming
call is a FAX or a data call. If it is a FAX call, BGFAX receives the
FAX and stores it on disk in a proprietary format, which is
convertible to PCX or the format used by QL2FAX (a program usually
bundled with modems). Various data about the call is stored in a
log-file. There is also a program with it that makes you able to
transmit FAX'es. It is shareware and costs $25 USD to register. It is
simple, using a no-nonsense non-GUI style userinterface. It is shipped
with a document, which is also a no-nonsense type making efforts to
explain the (chaotic?) world of FAX/modems. For the unexperienced user
it can be hard to understand, but unless you have a very odd modem it
looks like you should be able to make it work (Said by the
unexperienced user ;-)
If BGFAX detects that the call is not FAX but data, it attempts to
load a BBS program, set to be loaded by a front end processor. This is
the way I have set it up, however it seems that originally BGFAX was
made to make Fido Net SysOp's able to receive FAX'es on the same line,
so BGFAX can also be loaded in a another way, called Rear End Mode. I
didn't try that, but if you are a Fido Net SysOp you probably already
know about it.
Having entered the BBS, all control is taken over by that so now the
caller will be able to do whatever he/she normally would. It is
because BGFAX works in the Front End Mode with Batch files calling
each other, so when the BBS is up and running BGFAX is totally out and
vice versa.
As stated before this is just a fun hobby, so I want it to cost as
little as possible. Therefore I have been searching for cheap BBS's
(and still are). In the beginning I tried Executive Host, which is the
BBS extension of Telix. However, I couldn't make it work and tried by
FAX and email to contact the people producing it, but I never got any
answer even though I wanted to register?! I also tried a totally
different approach, with a program called FreeMail that works with MS
Windows and should be able to receive phone and data calls by some
nifty software construction? But it weren't able to use a combined
FAX/modem and split those two, so I dropped that. I also got some info
about using QL2FAX as it has an "auto detect" option when answering
the phone. It would seem perfect to have everything in the same
package, but QL2FAX does nothing else but answering the phone? There
is no info on how to for example write a script to make it continue as
simple BBS, and at that time I was getting quite far in making BGFAX
work so I dropped that, too.
I finally made a BBS program called TriTel work together with BGFAX.
It is very simple, though it claims to be very powerful, but the
people that made it (shareware) wants $75 USD to register, so I am
still searching. Stuart Whitmore claims that Wilcat works well with
it, but that is a commercial software package costing $100 USD, so
that is not yet interesting.
A long story about getting connected in more ways, without having to
pay the (competitive?) price of $770 USD in (no-competition-land)
Japan for an extra telephone line (just to get connected). You realize
that a little extra sweat can save you a lot of money. A little more
"bashing" will hopefully eventually bring prices down (Go for it
Clinton! EU are too busy "bashing" each other ;-)
If questions are asked directly to me I will do what I can to answer,
at least now being able to claim that I have some experience.

Subject: Mandatory 1+ Dialing Coming to Area Code 516
Today's {Newsday}, 5/26/94, contained an article with the title "LI,
Get Set to Dial '1'".
Mandatory 1+ dialing to numbers in area codes other than 516 (Long
Island) will go into effect on Sept. 24, 1994. It now is and has been
optional for several years. Area code 914 is also affected by this
change but I cannot say anything about the other area codes in New
York with the exception of 212 (Manhattan), 718 (Brooklyn (Kings
County), Bronx, Queens and Staten Island (Richmond County) and 917
(cellular, pager, etc. that is an overlay area code.

I'm in the market for a micro portable cell phone and need some
advice. From what I've gathered it seems these devices are not too
reliable when it comes to clarity and battery life. Most everyone I've
spoken to has suggested I stay with the car phone and forget the
"pocket" phone. I suspect this has to do with the low ouput of the
units? If there is a manufacturer or a particular type of phone I
should get I would greatly appreciate such contrasting opinion.
Thank you,

Subject: How smart is call-forwarding?
Date: 26 May 94 06:39:36 GMT
Organization: Screaming in Digital, the Queensryche Digest
A question for those more knowledgeable than I:
Being out in the sticks and not "local" to the nearest dialup, I got a
line put in at a relative's house in an NXX bordering both my NXX and
the net's NXX a couple years back, with call forwarding on it. Simply
put, my connectivity looks like this:
[Me] -- [Fwd] -- [Net]
In my state (NJ) the telco (Bell Atlantic-NJ) has diligently replaced
all the trunk lines with fiber, much to my delight. Most of the
overhead wires are still copper, at least as far as residential lines
go, though. There's a fiber shed around the corner from my house, and
the transition is made at that point. Thus, we arrive at one of two
scenarios:
1) If BA-NJ's switching computers are smart and simply shunt calls on
to their forwarded destination:
[Me] -c- [Shed] -f- [CO1] -f- [CO2] -f- [CO3] -c- [Net]
2) If BA-NJ's switching computers aren't smart, and actually route a
forwarded call out to the number (over copper!) and back again(???):
[Me] -c- [Shed] -f- [CO1] -f- [CO2] -c- [Fwd] -c- [CO2] -f- [CO3] -c- [Net]
Recently, I've encountered _nasty_ noise. Even the latest greatest
28.8kbps modems with all the connection-holding capability in the
world can't connect. If I dial _directly_ without using the forward
(thus incurring big tolls) the routing is as follows, and there is no
noise:
[Me] -c- [Shed] -f- [C01] -f- ([C02] -f-?) [C03] -c- [Net]
(Note, I'm not sure whether a direct call would pass through the CO in NXX 2.)
It looks like one of two things is happening here:
1) The computers are dumb, and are routing the call out to the number and
back again, and something's causing noise on the loop.
2) The computers are ok, but something's causing noise in NXX 2's CO itself.
I'm going to call BA-NJ in the morning, and go through the usual
process of explaining to them that I'm _absolutely certain_ it's not
my inside wiring, since there _is no inside wiring_ on that line... ;)
but I figured I'd toss this out, in hopes that someone out there knows
more about how the computers handle call-forwarding.

Subject: Large Norstar Systems
We have some IWATSU IDS-128 hybrid switches that we will have to
schedule for replacement soon (new North American Dialing/Numbering
plan, a recently discovered method to totally defeat existing software
toll restriction in the things, age, parts, etc).
On option being studied (one of *many* options being studied) is to
replace the systems with Norstar systems. I am comfortable with the
Norstar in small configurations, but would like to chat with anyone
with experience in using/supporting large configurations (20X88 or
20X104, for example).
Thanks,

Somehow I missed the first article of this thread. But I assume you
are talking about an answering machine that when it receives a
message, it will dial a preprogrammed number to alert about the
message just received.
I would be interested in such a machine, either the one mentioned in
this thread or similar ones in the market. Any help with brands or
where to buy them, will be greatly appreciated.

Subject: Rude Not to Leave Answering Machine Messages?
General view of Digest readers (except Miss Manners) seems to be that
it is, on the basis that it leaves the called party with a gnawing
feeling of wonderment as to who called them and why. I can't see how;
do modern answering machines work differently from my fairly-old
Panasonic?
With mine, callers who hear the outgoing message all the way through
and then hang up (before the beep) just don't activate the message
counter, so I don't even know they called. The few seconds gap between
the end of the outgoing message and the beep gives them plenty of
time. Suits me fine, and I had assumed they all worked much the same
way.
Incidentally while I'm at the keyboard ... it's taken me a while to
realise that US analogue cellular systems providers require you, the
the phone owner and payer of the airtime bill, actually to pay for
incoming calls. How the heck have they managed to convince people to
go for that?!?
