Does anybody have any more information?  Does anyone know when they

I have to agree. I spend at LEAST $25.00 a month and with Sprint Sense
get
 .10 a minute from 7PM-7AM weekdays and from 7PM Friday to 7AM Monday
morning. So at that rate it comes to 250 minutes of talk time. If I'd
spent that with AT&T's TrueUSA it came out to only 192 minutes.

The best part was when the sleaze from MCI called me last night asking
if I'd switch to their new Friend & Family II. Ha! My reply? "Send me
a check for $75.00 and I'll think about it."

I'm waiting to see how many people do this with my data line which
makes
NO long distance calls -- I should make a fortune off that one.

     Yes, MCI is offering 50% off all calls fro six months to NEW
customers.  After that it is 25% off all calls if the monthly bill is
over $10, 30% if over $50.  The 50% discount will only be to other MCI
customers in your Friends & Family list.

     This is off the standard rates (generally just slightly less than
AT&T's).  It makes more sense than any other plan they have except for
intralata calls in Texas.  Other plans might make sense for that but
are being grandfathered by the company.

     In comparing New F&F to True USA, the rate will always be less
than AT&T, even without the 50% MCI to MCI discount.

ADSI is state-of-the-art technology -- for 1975. However, it is 1995,
and Bellcore's low speed, asymmetrical protocol doesn't meet today's
expectations for a multimedia information terminal.

A little background: ADSI provides 1200 baud signalling to the CPE and
a DTMF backchannel. So, ADSI is really slow sending info to the user,
and the user can only signal back in DTMF. This is inherently
limiting,
as you might imagine. ADSI also defines presentation capabilities
which allow the server to write text and options on the CPE screen.
However, this capability is text-only.

So, here we are on the brink of the Infobahn with cable companies and
on-line services promising users a rich multimedia world replete with
full motion video and CD quality sound and here's Bellcore offering
1200 baud text only services. OK, maybe the Infobahn stuff is a little
way out, but ADSI adoption hasn't exactly been earth-shattering.

By the time there is any appreciable penetration of ADSI phones (if
ever), people will have truly state-of-the-art capabilities in their
TVs and PCs. Meanwhile, the phones, phone companies, and telecom folks
(us) will look dumb showing off ADSI stuff. Furthermore, we would then
have a backward compatibility issue with these installed devices as we
tried to move into some new technology.

Therefore, we in the telecom industry should be pushing for a more
modern voice/data solution than ADSI, one which will carry us into the
next century. For instance, the Radish VoiceView protocol is a fully
symmetrical switched voice/data solution which allows data (anything,
not just text) to be carried at much higher speeds; the protocol also
allows negotiation for fax (unlike ADSI). We should see VoiceView
modems appearing later this year. Plus, digital simultaneous
voice/data
(DSVD) standards are coming soon (i.e. next year) which will allow
high
speed data connections plus voice on the same analog line.

Finally, I'm not sure how v.34 and ADSI finish off ISDN. If I'm
running v.34, I can't talk on the line. ADSI makes no provision for
interrupting a data call with voice or a voice call with v.34 data, so
these two things are unrelated. (Besides, I'd like to meet the person
who gets 115kbps reliably over real phone lines using v.34.)

(Other random thoughts: when the head of any RBOC talks about the
Information Superhighway, none of them has ever mentioned ADSI as a
key technology in making our future happen. If they don't believe in
it, why should we? Something else to keep in mind: who will be the
torch bearer for ADSI? Last I checked, Bellcore was for sale. Given
the uncertainty of their future, I wouldn't count on them to propagate
any standards.)

Thus, ADSI is hardly new (technology wise) and not very amazing. Just
say 'no' to ADSI.

No, you would put a resister on your phone.  Then, when you detected
the first ring, you would send "fake" caller-ID data which would fool
the callers box.  Is this possible?

[TELECOM Digest Editor's Note: No it would not work since anything you
do
on your phone only applies as far as the central office. If it were
possible
for me to do something to *my* phone which influenced the behavior of
*your*
phone then lots of folks would add resistors or whatnot to their own
lines
to fool the exchange into thinking *you* had not answered, thus there
should be no charge for the call, etc.  Remember the book and movie a
few
years ago called 'Tandem Rush'?  The sick phreak sits at home and
dumps all
this very high current on the phone line causing the phone on the
*other end*
to catch fire and/or electrocute the recipient ... yet it goes
unnoticed in
the central office ... balogna!  Whatever hardwiring you do on your
phone
only influences the behavior of your phone(s) and line(s). Once the
results
of your handiwork reach the CO maze, that, as they say, is that.
Notice I
said nothing about audio tones, just hardwiring. Anyway, if you put
this
resistor in your phone, then the CO would think you were the one *not*
off
hook and would never extend dial tone to you.  Or were you planning to
switch it in and out of the circuit as appropriate? As soon as you
switch
it in (if off hook) the CO will think you disconnected.  Won't work!

Subject: Re: Clock Slips Again


When using DS1 circuits, a switch needs to be timed with the rest of
the network.  On the switches I have worked on, I designate which DS1s

·
the switch should use for timing.  Check where your PBX is receiving
timing.

Assuming your switch is clocking off of the DS1 like it should be, a
second problem can come from having the clocking DS1 on SONET
facilities.  We have found that SONET DS1s have significant jitter,
and can not be used for timing.  We have gone so far as to require
special facilities from the LEC to avoid SONET routing.  With the T1
on SONET, your PBX may be unable to clock properly.  Ask your
telephone
company how the T-1 is routed to the central office.  You will need to
convince the LEC to keep at least one DS1 off of SONET facilities, and
program your PBX to use that DS1 for timing.

I hope this will give you a few more ideas.  Please give me a call or
EMAIL if I can help you more.

 One other reason for the 10 (11) digit dialing is that the NPA
and NXX in an area may be the same now that '0' and '1' are no longer
required to be the middle digit of the NPA.  So far it has been
avoided mostly, but in the future it will not.  If only seven digit
dialing were used in this case, there is the possiblility that the
switch will construe it as a misdialed number if only seven digits are
dialed if it thinks the first three digits are an NPA.  Granted the
software can be designed to get around this, but well ...

[TELECOM Digest Editor's Note: Its not that the software can be
designed
around this -- it HAS been designed. Ever hear of timeouts? If you
dial
something which can be interpreted in a couple different ways
depending on
what digits follow, if any, the central office will sit there a few
seconds
following your last key press waiting for more. Lacking any further
entry
on your end, translation is started based on the context of what you
did
enter. For instance, you dial just zero for the operator. It is going
to
sit there a few more seconds waiting to see if you plan to continue
dialing
with 011, or 01, or 00, or 0+area code and number, all of which are
valid
combinations.  To avoid timeouts and waiting, try dialing 0#. That
'pound
sign' on the end functions as a carriage return. It means the dialing
string is finished. Ditto with credit card calls to the number
associated
with the card; you only need to enter the four digits of the PIN. But
the
computer does not know what you are dialing, so it will sit there and
wait
to see if more digits are following. Terminate the PIN with # and
watch
how fast your call is processed. Anytime the number of digits to be
entered
is variable depending on context, use the # on the end to speed up the
process in the same way you were told to do with international calls.
Note that when you dial a seven or eleven digit number, adding # at
the
end does absolutely nothing to speed up the connection.     PAT]

The Elite was introduced in the USA about three months ago.  It is
smaller and lighter than the MicroTAC Ultra Lite, which was Motorola's
previous lightweight champ.  Aside from the electronic feature
improvements, physical presentation is the big news for this model.
Until now every last one of Motorola's "Flip Phones" was designed so
that its accessories (batteries, cig adapters, car adapters, modem
adapters, etc.) would interchange with any other Flip phone.  As I
understand it, the new Elite cannot share accessories with any other
model of Motorola phone.  This may present you with "new product
accessory availability" problems which were not present, for example,
when Motorola introduced the MicroTAC Ultra Lite a year and a half
ago.

The phone has more features than you can shake a stick at and is
extremely light.  I'd have purchased one instead of the MicroTAC
Ultra-Lite I bought two days ago, if it weren't for the fact that
street price in the U.S. is a little over US $1000.  The street price
on the Ultra-Lite is less than half that.  (Of course, actual price
depends on what kind of deal you can get with your service plan.  With
the plan I got, I received $150 off any phone in the store.)

Please note that I work in the Infrastructure group at Moto, not the

Ameritech now offers what they call "Access 24" in many areas of
Detroit and suburbia, a service which offers Caller ID combined with
Call Waiting.  You must purchase a whole new phone to use this
feature; Ameritech offers this phone for, I believe, a cost of around
$250.  The phone, produced by none other than Northern Telecom,
features "soft keys" that can be pressed to instantly access other
custom calling features; the screen will display Caller ID information
of normal incoming calls and of calls that are waiting.  This
particular
phone is supposed to also be compatible with future home banking and
other electronic services.
