Subject: V.25bis, or: Are CCITT and PTTs Totally Bonkers?

I borrowed a MultiTech V.32 modem to do some testing, and while
waiting for something to complete I thumbed through the manual and
came to a curious appendix at the end: "CCITT V.25bis Operation".

After explaining the differences between normal commands and V.25bis
commands, there was a section entitled "Delayed and Forbidden
Numbers", which I quote below:

"V.25bis provides the facility to delay failed call retry attempts by
putting numbers that failed to connect on a special Delayed Numbers
list.  Subsequent dialing of these numbers will be delayed (time
specified by a country regulation) and an appropriate message
displayed.  If the number is retried more than the maximum allowed
number of times (also specified by country regulation) it is placed on
the Forbidden Numbers list, and no further retries will be allowed.

[...] Numbers are removed from the Forbidden Numbers list after a
certain time has passed (also by country regulation).  Some country
regulations have numbers remain on the Forbidden Numbers list
permanently. [...]"

I looked at this for a while, and thought it might be some sort of
inside joke among modem manufacturers, and then I came to the
per-country regulations and operations guide:

"SWITZERLAND

[...] b) Delay and Forbidden List behavior

1. Two minute delay between four retries.
2. After four retries the number is put on the forbidden list
3. The number remains on the forbidden list forever."

Austria and France are similar; Belgium, Italy, and Singapore use a
120-minute timeout for removing a number from the Forbidden List.

OK, I can see that a PTT might want to have some reasonable
regulations that restrict automatic redialing by modems and similar
devices, to prevent older switch equipment from being overloaded.  But
 ... a Forbidden Numbers list?  With numbers that stay on it FOREVER??
Have these people totally taken leave of their senses?  If I dial up
my local BBS in Zurich, and the system is down, and the modem doesn't
answer four times, I am Forbidden from ever trying it again?

I assume that either I am not reading something right, or that V.25bis
is optional/voluntary, or outdated, or something, but I really can't
imagine what reasonable thoughts were occurring in the heads of the
people that thought up this scheme.  Does anyone have any ideas about
what CCITT was trying to accomplish here?

Not necessarily true. DEC uses their cables as null-modems by having
the 'twist' in them. The wiring for RJ-12's is:

White = DSR
Blk   = Rcd
Red   = Grnd
Grn   = Grnd
Yel   = Txd
Blu   = DTR

So if you have a 'twist' cable connecting two devices, the effect is a
null-modem (DSR <> DTR, Rcd <> Txd).

I believe the RJ-45 setup is the same, plus RTS <> CTS.

   You're close, PAT.  The specified announcement is required by
Bellcore's TR-530/FSD 20-24-0000 Interconnection requirements, in
Section 3.3.2F, when a caller dials 10XXX in a CO that only offers
950-WXXX access to the XXX-specified carrier -- in other words, to a
carrier that only wants to pay for FG-B trunks.  Bellcore's preferred
wording (from SR-TSV-002275, "BOC Notes on the LEC Networks - 1990"),
Table 6-54:

    "We're sorry, the long distance company access code you dialed
     must be preceded by the digits 950.  Please hang up and try
     your call again."

   Those fortunate enough to also have TR-NPL-000275, "Notes on the
BOC Intra-LATA Networks - 1986", will note that Table AU in Section 6
also shows this as List 228 on the CK-22550 standard announcement
tape.  (The 1990 document deletes many details from the 1986 version.)
You'll also note the announcement is slightly different:

   "We're sorry, the long distant company ...."

   Either way, the GTE recording is about a clear (or un-clear) as the
Bellcore version.  So now, John, you know WHY the announcement EXISTS
in the GTE switch.  As to why "0" would yield the announcement, it's
obviously a screw-up in specifying the correct routing for that digit.

   Note that with the divorce of FG-B XXX codes from FG-D codes and
the expansion to four XXXX digits for both by 1995, this particular
announcement (and it's twin, where 950-WXXX should have been 10XXX)
will no longer be meaningful.  I doubt if many companies even bother
to use the announcements.

   For further reference, see:

TR-NWT-000690, "IC/INC Interconnection FSD 20-24-0000", which
               replaces the TR-530 bundle of FSDs.
TR-NWT-001050, "Expansion of Carrier Identification Code Capacity for
                Feature Group D (FGD)"

I got the new 1339 about six weeks ago.  As far as I know (not having
had a 1337), all the 1339 adds is time-and-date stamp, voice
announcement of number of messages, and more memory.  There is no

I am pleased to announce that GTE has finally fixed my DISA, over one
year after it stopped working.

My Direct Inward System Access lets me access my home centrex system
when I'm out of the house.  Over one year ago it stopped accepting my
security code.  Since then, calls to repair service have resulted in
nothing but the problem being "cleared", or worse, being told that my
DISA number does not belong to me so there is no way they can take a
report.  As recently as last week, GTE dispatched technicians to my
home (twice) to try to fix the problem (good diagnosis, GTE!).

After enlisting help from the business office, I was finally able to
convince someone at repair that I actually do subscribe to this
service, it used to work, it doesn't any more, and it's a software
problem so stop sending people to my house.

The message finally got through and they fixed it on Friday.  While I
had their attention, I asked if they could please change my security
code from 1234 to something a bit more secure.  "Sorry, it's
hardcoded" was the reply.  I don't believe it.  And I am surely not
going to pay for any calls when someone discovers this.

GTE ... I'm still not impressed.

Heard on Paul Harvey Monday ...

A reader noticed an item in a Kentucky newspaper: Apparently an
elderly woman called up the complaints department of telco, saying
that her phone cord was too long and she was afraid she'd trip over
it, fall, and hurt herself.  Her request to the operator went like
this: "Now, dear, if you could just start pulling in on it from your
end, I'll let you know when you've taken in enough!"

  :-)

Ummmm, careful there.  I'm not sure (since he mentions a "notch") that
he means an MMJ.  There's also the "keyed RJ45" still floating around
out there.  Whether it's RJ45keyed *or* MMJ, the answer is still "no",
though, the regular RJ45 plugs will not physically enter the jack.
(This is an entirely different problem from the fact that everone
seems to have chosen their own standard for not only what to carry on
each pair, but even which pins go to which pairs, and even which pins
*are* paired.  Anyone who can explain the logic behind the AT&T pair
arrangement wins a prize.)

As far as I know, our PBX never gives voice intercepts (but it is very
fond of reorder).  Also, the intercept does have the standard SIT
tones.

The problem only occurs if I try and dial it as a normal PacBell call,
that is, by dialing 9 for an outside line, then 1-213-663-xxxx.  If I
dial it via our long-distance network, or via MCI or Sprint, it works
fine.

Perhaps someone already commented on this, but it should be noted that
Graybar was originally co-founded by Elisha Gray, who contended to his
death that he filed a telephone patent hours before Bell did and was
thus cheated out of fame and fortune.  And Graybar became a subsidiary
of Western Electric til it was sold off in 1928.

AT&T to axe six offices in aim to serve 'efficiently'.

By Kent Gibbons
The Washington (DC) Times, Saturday Aug 29, 1992, Page B5

   AT&T plans to shut six of 18 customer service shops in November,
although one in Silver Spring [Md.] will remain open, the company said
yesterday.

   The closings will affect 860 union workers and 83 managers, all of
whom will be offered other work within the company if they qualify and
are willing to relocate, American Telephone & Telegraph Co. Spokesman
Mark Siegel said.

   The offices, where AT&T employees field questions about service and
billing are being closed to serve customers more efficiently, Mr.
Siegel said.  He would not elaborate, saying that would reveal to
competitors secrets about AT&T's call traffic.  But he said the
offices to be closed were targeted on the basis of their staffing,
technology and operating costs.

   A union official said the plan "may satisfy some ill-conceived
management scheme, but hundreds of working people, thousands of family
members, and communities in six states will suffer."

   The official, Communications Workers of America Vice President
James Irvine, said thousands of AT&T union members have become
"high-tech migrant workers, following their jobs from one closing
office to the next."

   Job security was a key issue in union contract talks with AT&T this
year.

   Union employees who are not placed in other jobs will be given job
retraining, counseling, outplacement help and up to 104 weeks'
severance pay depending on length of service with the company, Mr.
Siegel said.

   Offices to be closed are in Columbus, Ohio; Mobile, Ala.;
Parsippany, N.J.; Radnor, Pa.; St. Cloud, Minn.; and Wauwatosa, Wis.

   Remaining offices are in Silver Spring [Md.]; Atlanta; Bloomington,
Minn.; Charleston, W.Va.; Dallas; Itasca, Ill.; Kansas City, Mo.;
Phoenix; Pittsburgh; Pleasanton, Calif.; Providence, R.I.; and San
Antonio, Texas.

Some time ago I picked up a phone connector at an electronics gadget
store that is supposed to "convert" an American "modular" phone to a
British modular plug.  The American end is the "typical" one I'm used
to seeing.  The "British" end is somewhat larger but has a similar
type of "push in" connection.  (Love the technical terms!)

I am planning on giving a "nice" phone to some friends over there for
Christmas.

Now I know that I could not select any phone that has features
requiring electrical connections and expect a direct connection, but
what is the likelihood that making a connection for the other end is
going be a hassle?  Are modular wall outlets common?

For any British folks reading this -- what would be a "nice" feature
set on a phone for you to get as a gift? I haven't been in a lot of
private homes, and am not sure if things like programmable speed
calling, speakerphone etc. are appealing -- or would the cutesy phones
(Mickey Mouse, Kermit the Frog) be more appreciated?

Is this going to work on touchtone -- or will it have to be set to
dial-pulse?

Feedback appreciated.

Go down to Radio Shack and get one of their "special" adapters. The
one you want in this case is one that plugs into a wall jack and
provides 3 output jacks: L1, L2, L1+2.

The L1 and L2 jacks have *only* the center two wires connected. This
tends to be necessary with modems because many of them have "feature"
that shorts the second pair of wires (the black/yellow pair) together.

If that doesn't work, you'll have to go for desperate measure like
replacing the regular four-conductor phone wiring with *real* twisted
pair wiring. If you check, you'll discover that your internal house
wiring *isn't* twisted pair! Thus, all the crosstalk.
