- Well, John, for once we got you. :^)
-
- The Operator Services Position System (OSPS) is a one size fits all
- position that does just about anything imaginable that an operator
- would need to do (other than directory assistance). Your center
- handles calls for the LEC? No problem. OSPS tells you what company
- name to brand the call with. Need to count coins? No problem, OSPS
- will do that, too. Etc. Etc.
-
- As you will recall from our private correspondance, I trained to be an
- OSPS operator as part of last summers labor relations jitters. One of
- the things that could show up on your screen with an incoming call
- were the messages ONI FAILURE and ANI FAILURE. In those cases you
- hand to ask the customer for the number and then complete the call.
-
- The training materials also indicated that there were a few offices
- (probably in ICO land) where the calling number had to be collected
- for every toll call. Since AT&T operator services centers cover a
- much wider geographic are than those little end offices, nobody gets a
- majority of such calls, but we were all trained to handle them.
-
- The only kicker is that I don't remember off-hand whether ONI or ANI
- hit our consoles only for 0+ calls or also for 1+ calls. The only
- thing that would argue against Pat's scenario is if ANI failure
- bounced the call on a 1+. I just don't remember. Certainly nothing
- in the features of the OSPS console would preclude collecting the
- billing number from a customer-dialed call in the event of ANI
- failure.
-
- A digression:
-
- This baby is *very* flexible and *very* well designed. After the
- "two-phase commit" model of collect calls was adopted (operator A
- hears you say collect, releases the call, your party answers and
- operator B does the name game) these things keep operators very busy,
- too. What used to be holding time for an operator is now holding time
- for a switch.

- So my question is this: What happens when it is my Trailblazer or fax
- modem that is making the call? Even though the Trailblazer and the
- Brooktrout are very fine modems indeed, I do not believe they can
- answer a "Your number, please" inquiry. Obviously, the call fails at
- that point, since the operator just dumps it--probably thinking there
- are some kids or a crank at the other end of the wire.
-
- Now, given that the number of calls generated on the network by
- automatic devices is increasing exponentially, feeble attempts to
- "rescue" a call via operator intervention would seem to be a complete
- waste of time and resources.
-
- I guess what I am trying to say is, "why bother?" Just let the call
- die; why take up more time?

- [Moderator's Note: *All types of calls* are increasing in volume. Fax
- and voice calls are the way business operates these days: no one
- writes letters, at least not in any quantity as they did 30 years ago.
- Calls from automated devices (modems, etc) are still just a small minority
- of the total. Yes, there are lots more such calls, but the ratio is still
- the same. Offices all over the USA have thousands of clerks sitting in
- cubicles banging away on the phone all day. So yes, calls from automated
- devices fail to complete and are aborted when the operator can't get a
- response she understands from the 'caller'. PAT]

-
- You have just discovered one of the great, gaping holes in my telecom
- experience. I have NEVER had service provided from a SXS office. Yes,
- it is true, I have had no service in my name provided from anything
- more vintage than crossbar. Now that is not to say that I have not
- beat on the telephones of friends and associates that have been served
- out of SXS, but it is not the same thing. (Even when growing up, it
- was panel, then crossbar.)
-
- I lived in North Carolina for a time in an area served by Southern
- Bell step. There was a phone in the house that we all used and it was
- interesting to note that most of the time long distance calls went
- through without operator intervention, but occasionally an operator
- would come on the line and ask for the number of the calling phone.
- Your comments explain this little mystery.
-
- Except for some SXS on the peninsula (Mountain View, Palo Alto,
- Redwood City, and San Mateo), the Bay Area has been served by crossbar
- and panel before the electronic stuff came along. San Jose's first
- dial equipment was crossbar; San Fransisco's was panel. In fact, the
- only SXS convenient to play with anywhere near me was Los Gatos.
- Before GTE swallowed it up, the Western California Telephone Company
- had the most rickety SXS the ear has ever heard. It was so stupid that
- to call San Jose (a local call), it was necessary to dial '9', wait
- for second (tandem) dial tone, and then dial the San Jose number.
-
- When GTE moved in, it became the usual vile directorized SXS that GTE
- is infamous for.
-
- But back to the present. Nowadays, I would be willing to bet that ANI
- failures (if they occur) would simply cause the call to fail. In an
- age of fax machines, modems, and other automatic dialing equipment, an
- operator coming on the line to ask, "Your number, please", seems
- rather pointless. Gee, I wonder how many times any of my Trailblazers
-
- has been asked for ITS number?
-
- And, of course, it is all moot now. The face of ANI has forever
- changed with SS7. There can no longer be any "ANI failure".

- [Moderator's Note: Of course there can still be a failure to capture
- the number and pass it along. As noted above, when that (rarely)
- happens -- given the huge amount of network traffic -- an operator
- picks up the call, punches in the quoted data and releases the call
- back to the equipment which then adopts the operator's forced input as
- its own. But I am talking about an infintesimally small fraction of
- one percent of all calls having this happen, which is as good as
- saying it does not happen, lest the average customer clutch on it as a
- way to resolve all billing disputes. It is like the old cliche about
- computers 'never making mistakes'. Of course they don't. Of course
- they do. Which response would you make to the average (not telecom/
- computer-saavy) customer?
-
- One response recieved here when using my SS-7 features (call screening
- [add number of last call received], return last call, and Caller-ID)
- is 'I am sorry, the number is not available now' (on the ID box, the
- message is 'Error' or 'E') as opposed to 'I am sorry, the feature you
- are requesting is not available with that number' (on the ID box the
- message is 'Outside'). Other times when you try to add a 'last call
- received' number to your blocked list, the robot goes away silently
- for the longest time (20-30 seconds) and comes back to report "That
- number cannot be added *right now* ... try again in a few minutes."
- I assume the CO was doing something like trying to 'finger' the number
- in the other CO but getting no response to the finger-request. PAT]

- Look, if what you want is stability, go ahead and nationalize the
- network. Be prepared for zero customer service, high prices, and
- outright hostility toward installing new equipment that might
- eliminate paying positions. As Mr. Clinton himself pointed out, the
- government isn't interested in change as a way to get rid of
- high-paying jobs -- jobs which, if dropped, could also result in the
- customer getting the same service at a lower cost.
-
- We all know the two answers the Feds have about reducing the price of
- anything: either it gets subsidized, or they install price controls.
- For the former, the Feds fondle your money for a while before handing
- less of it back to you. For the latter, you will wait three months to
- get service. Almost certainly, you will get the worst of both worlds:
- lousy service AND high prices.

-
- The telcos do not have much of a choice in the matter if they want to
- stay alive. In the 1950's, the railroads forgot they were in the
- transportation business. The Interstate Highway system created the
- long-haul trucking industry, relegating railroads to stale markets and
- old technology. If the telcos now make a similar mistake with the
- "data superhighway," they will almost certainly face the same doom.
- Gore's proposal should serve as a cattle prod for telephony.
-
- So if the telcos want to keep what they have, they'd better start
- laying plans to lay fiber, everywhere and soon. The payoff is that
- they can push video through their newly laid pipes, thanks to a
- fortuitous court ruling. I'm not exactly happy with the telcos
- providing content, but the fact is that the cable companies do exactly
- that now. With the world going digital at picosecond speed, cable
- operators and telcos look increasingly like the same thing. The ones
- with the best capitalization, customer service, and price will win.

-
- Okay, I also got some mail on this. To elaborate, this is regarding
- the AMPS cellular standard (used for North America). Every phone has
- a MIN (Mobile Identification Number) composed of MIN2 (the area code)
- and MIN1 (the seven digit phone number). If you want to send a
- message to a phone, such as "There's a call for you!" you identify the
- phone by its MIN. The mobile watches for messages that contain its
- MIN and should respond to those. In addition, the MIN (along with the
- ESN) is how the mobile identifies itself to the system.
-
- Now here's where the fun begins. MIN1 and MIN2 are actually special
- representations of the digits in their numberical forms. In other
- words, 619-555-1212 isn't stored as a MIN2 value of 619 and a MIN1
- value of 5551212. They each go through a "massage" of the digits that
- is totally dependent on the form of the data (i.e., three digits in
- one, seven digits in another). This is a standard, and it is not
- flexible.
-
- work. They would have no idea how to decode the numbers. If you used
- a somewhat compatible scheme they might be able to get the seven
- digits they are used to, but that's about it. And, of course, all the
- switches and cells that are out there are probably wired for
- seven-digit AMPS as well. It's not like a regular phone system where
- the phone company figures out which line to ring, then rings it -- in
- this case it's up to the phone itself to decide when to ring.
-
- The only thing I can think of on short notice that would be minimal
- pain would be for the switches (MTSOs) to be modified to convert from
- eight digit format (external world) to MIN1/MIN2 format (mobile world),
- and then to use an extended data field so that those mobiles that did
- know about eight digit format could use it.

- Subject: Comment About Terrorism
-
-
- Pat Townson's comments about the future of America were something that
- hit home. I was once asked by a bus driver about things to come:
-
- Count on it; the violence in the cities will not get
- better and will get worse. The recent incident will
- be just a taste of the kind of thing that will happen
- so often that the papers won't even report them until
- the body count goes above 100 or more. Count on
- random acts of violence without purpose or reason.
- And expect the imposition of Martial Law in major
- cities. Making a prediction like this is about as
- difficult as predicting an egg will crack while it's
- on the way to the floor.
-
- When I said it, it was *1980* and I was referring to the
- *Miami Riots*.
-
- The real question I wanted to ask, if you knew it, was the name of the
- Made for TV movie written by either Woodward or Bernstein, about a
- group of major terrorist attacks upon the United States, when they
- finally begin to take place.
-
-
- [Moderator's Note: I forget the name of that movie, but another one
- which comes to mind is 'Escape From Manhattan' which came out several
- years ago. As the movie starts, we are informed the year is 1993, that
- 'violent crime in the USA has increased 400 percent in the past two
- years', and that because the government had run out of prison space,
- the island of Manhattan had been evacuated and was now used exclusively
- as a penal colony, with the prisoners left to their own devices about
- how to survive, what to eat, etc. All bridges or other exits leaving
- Manhattan had been sealed or were heavily guarded. An airplane flew
- overhead once a week and dropped out food supplies.
-
- America changed last Friday. The land where the only battles on our
- own soil were those we fought amongst ourselves is gone. Expect the
- nineties to be the decade of random killing and violence for its own
- sake. And wait until next month when The Jury finds the police officers
- innocent ... social order in urban America will erode completely. I
- rather suspect we may be living under martial law by this summer. PAT]
