Some modems have this built in, I hear.  For what you want, this may
be the cheapest way to go.  I recently got a "selective ring
processor" listed in the AT&T Sourcebook (800-451-2100).  They sell a
two number version for $100 and a three number version for $130.  I'm
happy with the three number version I'm using.  It has (switch
enabled) lockout so you can prevent one device from going on the line
if another is offhook.  I have found this useful to prevent me from
accidently barging in on an incoming fax, as I have the ringer turned
off on the fax machine.

Incidently, this approach was suggested by several comp.dcom.telecom
readers in response to my query about voice/fax switches last month.

I'm having a problem tracking down CRC errors in a new phone line.

I had a second phone line installed in my new apartment for use with a
modem.  The second line uses the same wiring as the first line (but
the opposite two wires black-yellow, green-red).

I'm using a Zoom V.32turbo modem hooked up to the comm2 port on my
Gateway 2000.  I'm using DOS5.0 and Telix v3.15.

I used to be able to get about 1350 cps at my old apartment virtually
error free.

Now, however, I'm getting tons of CRC errors and I can't figure out
why.  File tranfers have dropped to around 1000 cps (from 1350) and I
get random CRC errors roughly every 30kbytes of the transfer;
sometimes the modem drops the line.

I can only assume it's because of line noise.  But I don't know how to
track down where the noise is coming from (i.e. is there a shorted
phone cable somewhere in the house or is the problem elsewhere).

How can I track down the line noise problem or even better, is there
some device that will improve line quality enough to eliminate the
errors?

Barring that, can the phone co. check the line quality of my lines?
I'd like to solve this without having them come in at $50/hour to
diagnose it.

Don't forget that the digit mapping (number of LD pulses versus number
keyed or dialled, does vary.  In New Zealand if you DIAL 7, the phone
sends THREE disconnects. In some other countries it would send EIGHT!
The work around is to "translate" the digits before you ATD them.

When do we use the two-wire E&M or four-wire E&M? Is anybody out there
who could tell me where the CEPT/ETSI is published?  Why do
telecommunication professionals always say -48Vdc not +48Vdc?

When the trunk equipment is linked with the signaling circuit, what's

Regular NO22 or NO24 gauge station wire can be spliced by using just
about any kind of common splicing device.  Of course,if the wire is
going to be exposed to the elements, the splices must be air and water
resistant, but in-doors, one could use anything from wire nuts to
crimp terminals as well as solder and tape.  Another variation is
solder and heat-shrinkable tubing.  Some heat-shrink tubing is even
rated for out-door use.

     Several years ago, we had a tremendously bad period of rain which
flooded the cable tunnels under the Oklahoma State University campus.
The telephones were out because water had breached the outer covering
on a 2400 pair cable and converted it into a 2400 channel audio mixer.
After the technicians had found the internally soggy cable, they
replaced it.  While I have no idea what method was used to splice each
pair of wires, I do know that the technicians were seen taking whole
tubes of RTV silicone rubber caulk, cutting the bottom of the tubes
open with a pair of tinsnips and stuffing large bundles of spliced
connections into the tube so that they would eventually be encased in
a capsule of hardened rubber.  It seemed pretty down-to-Earth and
practical when you consider that this practice probably saved a lot of
man-hours.

What I want is something the receptionist can put in her pocket and
carry around with her so she can tell when the phones ring when she's

if it could be triggered by a ring signal.  Any ideas?

I do not personally have any experience, but a friend of mine who was
originally trying to get me to switch (for those not in the know,
Working Assets channels the money you spend on long distance into
contributions to various groups doing good things -- for example, you
could have your money go to Greenpeace) told me not to switch, because
she said she suddenly got a HUGE phone bill.  Apparently, Working
Assets raised their rates or changed their agreement with whatever LD
company they worked with and didn't bother to tell her (or did and she
didn't read her bill correctly).  Either way, she wound up with a bill
over twice what she thought it should be.  She cancelled with Working
Assets very quickly (after paying the bill).

It is my understanding that Working Assets Long Distance is run by
Sprint on the technical end i.e. calls are handled on the regular
Sprint network.  Since WALD doesn't appear to have their own 10XXX
code, I'd bet that it is just Sprint's standard 10333 with the billing
handled specially.

I spoke with a friend that has had Working Assets Long Distance for
some time, and he said that he's been really satisfied with the
quality of the service.  The calls are indeed carried by US Sprint,
and by checking the 1-700-555-4141 number from his line, it says
"Welcome to Sprint's long distance services", so the PIC is just
Sprint's standard 10333.  His calling card access number is different
from the regular Sprint FONCard access number, though.

I really don't know much about it. It seems to have been the default
for all the old multiline office phones. I rather suspect that it was
simpler to run the power for the lights in such a way that they got
turned on when the line got picked up.

Personally, I doubt that the old key systems were up to monitoring
loop current in a reliable way.

I've only ever had a use for three different codes: 10222, 10288, and
10333.  I'm sure that sophisticated users need many more than this,
but are four digits really necessary? Is there a reluctance to re-use
old codes freed up because of mergers, bankruptcy, etc?

All phone numbers in France were changed to eight digits on October
23, 1985 at 2300 hours.

The actual switching was done in less than a minute and you could a
real time display of the change on a special news broadcast on TV
after the Minister of PTT pushed "the" button.  The change was
advertised to the general public about a year before it took place.

The previous numbering scheme was on the form (AC) XX XX XX or (A) CXX
XX XX. The number in parentheses was the area code.  Paris had area
code 1 with seven digits numbers.

Since the change there are two dialing zones: the Paris Region
and the rest of the country.

Numbers outside the Paris region became (no area code) AC XX XX XX
Numbers within the Paris Region became (1) AC XX XX XX 
Numbers for the city of Paris became (1) 4X XX XX XX

Example: A number in Rouen that was (35) 71 84 00 is now 35 71 84 00
         A number in Lyon that was (7) 342 45 67 is now  73 42 45 67
         A number in Versailles that was (3) 237 89 01 is now (1) 32 37 89 01
	 A number in Paris that was (1) 787 11 11 is now (1) 47 87 11 11

During the first few days we would have a recording instead of a
dialing tone reminding us to dial eight digits.  Then for a few month,
if you dialled only six or seven digits there would be a timeout and a
recording.

Plans currently exist to eventually have all numbers in France be of
the form (Z) XX XX XX XX. (ie to implement more zones.)

To reach someone in the same zone you just dial eight digits. to reach
someone in another zone you dial 16 + zone code (ie now 1 for Paris,
nothing for the rest) + eight digits. You have to wait for a second
low-pitched dial tone after 16. (It comes immediately on digital
exchanges and with a delay of 1/2 to two seconds on analog exchanges.)

Not according to what I've read.  Call set up protocol with SS7 (By
the way, I strongly doubt you were SS7 connected) currently utilizes
"distant end" ring back which is a strong indication that all went
well with YOUR LEC and MCI, but the ball was dropped by the distant
LEC, when your aunt answered.  The good news is that since "cut
through" did not occur, a billing record was never completed either ...
whew!

> Is MCI connecting their SS7's to the LEC's yet?

Not officially yet, full SS7 connectivity between LEC's and IXC's is
on a lottery basis for priority of who gets connected first.  However,
there is much testing of interworking of networks at all levels which
is going on and must be completed before such interconnections are
turned up to live traffic. (Hint ... if the post dialing delay is in
the order of four to six seconds, your are not yet SS7 connected
between your LEC and IXC ... that's about the length of time it takes
to transmit FG-D data over Multi Frequency trunks up to the IXC and
back to the far end LEC).

This story appeared in {News & Views,} Michigan Bell's billing insert.
I didn't see any copyright on it, and I assume they would like wide
distribution, so I scanned it in.  

        NEW AREA CODE WILL ADD MILLIONS OF TELEPHONE NUMBERS

In 1994, a new area code will be added to southeast lower Michigan --
810.  The new area code is needed because southeastern Michigan is
running out of phone numbers.  The increasing popularity of fax
machines, cellular phones, pagers and computers has used up telephone
numbers at a rapid pace over the past few years.  Establishing the new
810 area code will create more than three million additional telephone
numbers.

Some important things you should know about the creation of the new
810 area code are:

+ It won't raise anyone's rates -- even if you have to dial an area
  code for a number that you didn't have to before;

+ No one's local calling area will change; and,

+ Your basic, seven digit phone number will stay the same.

Who will get the 810 code?

Customers in Oakland, Macomb, Sanilac, Lapeer, St. Clair and Genesee
counties, as well as small sections of Saginaw, Shiawassee and
Livingston counties.

And who will keep the 313 code?  Customers in Wayne, Washtenaw and
Monroe counties, as well as small sections of Jackson and Lenawee
counties.

A seven-member advisory committee spent months studying and talking to
customers before recommending how best to establish the new area code.

The addition of the new area code will affect millions of people, not
just in southeastern Michigan but across the country. But from now
until Aug. 10, 1994 (that's 8-10-94), when the change will occur,
Michigan Bell will carry out a massive program to educate customers.

In the meantime, if you've got a question about the new 810 area code,
just call us toll-free 8:30 a.m. to 5 p.m. Monday through Friday at 1
800 831-8989.

We're committed to helping you make the transition to the new 810 area
code as smooth as possible.  We're just a call away.

I need to connect a dead (i.e., not connected to a line) telephone
into an audio system (via a mixing console) for a play I'm doing sound
design on.  Unfortunately, I'm not as knowledgeable about telphony as
I would like to be, although I've done some hacking on phones
connected to a line before.  I previously connected a live phone into
an audio setup at home, but I'm not sure how to go about it without
having the line attached.  I read something once regarding small
intercom systems using telephones which said something about putting
9VDC through one of the wires, but I don't even remember which wire it
was supposed to be.

What I need to know is:

1) What do I need to do to power the phone?
2) What effect will this have on the rest of the system?

In case it's relevant, the idea is to use the telephone as both prop
and mic on the stage, feeding the mic input into a mixer channel to be
sent out to four to six house speakers, along (of course) with signals
from other audio components.  Would this require changes to the signal
strength from the phone, or is it a standard mic level?

Thanks for any help.  Post or E-Mail replies; I'll post a summary if
it's wanted.
