Subject: Question About Digital Telephony and Delayed Dial Tone
Reply-To: kris%sanctum%paladin@uunet.uu.net
From: sanctum!kris@uunet.UU.NET (Kris)
Date: Tue, 19 Apr 1994 23:54 EDT


I have a question that I hope someone can answer for me.

With the advent of digital telephony, 1.5 megabit and higher lines
running to each house, and even higher bandwidth on the poles, how
much less is the potential for a delayed dialtone situation such as
what was experienced during several of the many storms the Northeast
has had this winter?

Our area, like most, is being strung with new aluminum-encased cables
by the local Cable TV company which would soon provide a huge amount
of digital information, and (hopefully) dialtone service to compete
with our local telephone monopoly.  Since there is no longer any
physical switching of the connection and more of a "sharing of
bandwidth" among subscribers, how is overloading and/or delayed
dialtone handled?  Does the 64 kbit stream of voice data get broken up
as the line is loaded down, much like Internet FTP transfers are over
a TCP link?  Would a subscriber be visited with a delayed dialtone (or
a message telling them circuits are busy)?  Wouldn't the number of
concurrent dialtone users be increased substantially so as to avoid
this situation substantially?


Thanks,

Kris

To all:

Thanks in advance ...

Is there a difference in how the fractional T-1 is delivered to a user
whether it is inter or intra-LATA?  As and example if I want a 128Kbps
fractional T-1 is it a Tail Circuit from the C.O. where my DSU/CSU is
slaved to a 128Kpbs reference from the C.O.  or is it a T-1 from the
C.O.  with 2 DS0 channels being used in a DACS?  Or am I totally
messed up?  What is the proper way a fractional T-1 gets delivered to
a user via inter and intra-LATA?

Subject: PacBell Billing Exceptions to Cell, Page, Other WAC Subs


(Please send all replies to Ulmo@Pyrzqxgl.Q.Net, as replies to the
above sending address do not work.)

My goal: Payphones calling my Cellular be a local 20 cent call.

Result:  Not yet; I just have to give people my 800 number.  
         Details follow.

Prompted by a descrepency in Pacific Bell operator price quotes and
the claims of my LA Cellular Tel. Co.  representative regarding
pricing of PacBell->LACell calls, I called Pacific Bell Administration
(811-9000 from PacBell phones).  I asked for someone familiar with the
price contracts between LA Cell and Pac Bell.

Bob Duff returned my call.  He explained in perfect detail and with
great politeness the situation.  My LA Cell rep was right.  Companies
such as cellular, pager, etc. may sign up with PacBell for "wide area
calling".  A whole NXX code (prefix) is required to be assigned to the
company (he mentioned putting them into the access tandems).  Then,
everything within the (PacBell?) service area to that prefix is a
"local" (i.e. free or near-free) call.  The PacBell billing databases
bill this correctly.

However, there is a different database that both PacBell operators and
payphones use to do pricing.  This database knows an approximate
"location" for each prefix, and then the price quotes are calculated
on a formula according to mileage.  The result is that operators are
incorrect when quoting prices to certain cell and pager numbers within
the service area, and payphones use this older system to charge the
customers real coins.

Bob explained that the database for billing is so large that it's
difficult to update the database the operators use, but that Pacific
Bell plans to fix this within a few years.

Besides my obvious question of why don't they just plug the computers
together and use the same database (I forgot to ask), I was happy to
have the answer and decided I was ahead of the game because I knew
what was up and have an 800 number anyway.

Still waiting for the day that everything is flat-rate ...


-Bradley Allen aka Ulmo

P.S.  Any companies offering 800 service that I can change my target
at the touch of a button as often as I like (without the obnoxious
per-minute air charge my cell phone gives me)?

Subject: Re: Answering Machine With Voice Mail and Paging?


Fclark@deathstar.cris.com (Franclark) wrote to inquire about such
a combination.

Hi Frank,

Here's a not-so-elegant method I came up with.  You might be able to
adapt/adopt it:

Panasonic makes a series of speaker-phone/answering machines called
"Easa-Phone"'s.  I believe there are _several_ variations and models
(2-line, 1-line, # of memories, etc, etc.). They are all DTMF remote
controllable. Places like Circuit City, Service Merhandise, J&D, etc.)
will give you a selection. There's even a model (or maybe several now)
that will forward calls to a pager -- supposedly forwards the DTMF the
caller enters to your pager service... can't vouch for this. However,
here's the good news... ALL of the Easa-Phone's I've seen have a
"Transfer" feature.  All this does is to rattle your cage at a 2nd
number after a message has been recorded. Here's how I exploit that
with my pager -- also alpha-numeric, but a moot point for this trick!
Note: The TRANSFER memory can hold, I believe, something like a 13-14
digit number, so there's (barely) room for the PAUSE character, etc.

Program the number to TRANSFER to be your pager _AND_ a PAUSE
character or two (to buy time while your paging service rings and
answers!) _AND_ your answering machine's call back number (home,
work, whatever).  As a help to distinguish between my answering machine
calling me from home vs. my wife, et al; I program in the FULL number and
spaces which no one else would normally both with from within the same
area code, e.g.: 999-999-9999 (on your pager you can create the "-"'s
by hitting a "*" with most services). To me, that's not ambiguous -
only my answering machine (so far) has told me to "call home" and uses
an area code to do it ... no area code means it's likely a live human
bean.

The pitfall: You don't know before you call your answering machine who
called, but just that someone did. The machine will attempt calling
the TRANSFER number (your pager), I believe, three times. This isn't a
big deal to me -- I'd rather get paged three times with that number
than not at all.  Set pager to vibrate/one chirp if this "feature"
annoys you. I think of it as cheap insurance, but you may consider it
a bug!  Probably this'd only be good for folks with direct dialed
pagers.  Pagers using PIN's, etc; may call for too long a TRANSFER
number to be programmed (possibly you can daisy chain memories,
etc..!!).

Good points: The world doesn't know your pager number, or even
necessarily that their call is ultimately going to activate your
pager. _You_ decide how quickly to response. "Just got back to the
office..."  vs.  "Just got your message...". I like to wait at least a
couple of minutes so folks don't think I live at home monitoring the
answering machine on the local speaker! The Easa-Phones have a good
VOX circuit in them, if the caller is answering machine phobic then
and hangs up (no msg), then there's NO forward to bother you (to
retrieve a null msg!).

I know this is somewhat southern engineered, but it meets my needs!
And for the cost of a otherwise _EXCELLENT_ answering machine, it's
the most cost effective solution I've come up with.

WRT: Software - I love Ex Machina's "Notify!" - alpha paging software.
There are others.

> Thank you in advance for any information.

Yer welcome.

> Do I stand corrected? 

Back in the '60s and early '70s when I was growing up in suburban
Chicagoland, calls from our region to 800 555-1212 (we didn't dial 1+
back then), reached the SW Bell central office in East Saint Louis,
IL. I presume this service was staffed by SW Bell employees, under
some arrangement with AT&T Long Lines.

Since that time, SW Bell ceded its Illinois territory to the late 
Illinois Bell, as the Bell System redrew its operating companies' 
boundries to conform with state lines. (FYI: At about the same time, 
SW Bell picked up the West Texas territory of the late Mountain 
States Telephone, and the former Indiana Bell acquired Illinois 
Bell's Indiana territory.)

Subsequently, Divestiture further affected the inter-relationships 
of Bell companies and their (former) parent. If SW Bell, has kept 
its 800 DA operation (under contract to AT&T), it has almost 
certainly moved it, in order for it to remain within the SW Bell 
geographic domain.

I asked my sister (who still lives near Chicago) to check into this 
for me, and she reports that every inquiry which she made about 
their location was answered with "A Midwestern City." This may, or 
may not, be E. St. Louis.

>From here in Texas, my 800 DA calls have been answered in Chipley, 
FL for many years. (They have no qualm about saying where they are.)

So, to partially answer PAT's question, I think we can safely 
conclude that ...

At a minimum, Southwestern Bell "hosted" an 800 Directory Assistance
Operating Center several years ago, in a building it no longer owns.
SW Bell may or may not operate such a center someplace today, but if
it does, it's under a contract to AT&T, since AT&T has, to date, kept
the 800 DA "franchise."

We know that there's at least one 800 DA center operating in "A Midwest-
ern City," (possibly by SW Bell,) and at least one in Southern Bell's 
territory (Chipley, FL).

I wouldn't be surprised to learn that there are one or two more 800 DA 
centers in other regions of the US.
