My cellphone (Mitsubishi 1500), has a display mode that shows signal
strength and cell id.  Watching this as I drive around the valley
implies that I can go 10-15 road miles without switching cells.  Of
course, at other locations, I can go 10-15 miles without _finding_ a
cell, but that's a different story.  Cellular One has a map in their
office, noting where the towers are, so that you can make judgments
about coverage in your area.  I haven't seen the map, but I suppose it
shows the footprint of each cell.

This brings up something that I'm wondering about, as a cellular 
"newbie".

An office-mate and I just signed up with Nynex within the past three
weeks; we both bought Motorola DPCs from them, and they include a new
"feature" that I haven't heard of before: A four-digit PIN which must 
be
entered (followed by Send) after the desired number. (Calls to 911 and
customer service are excepted.)

Can somebody tell me a little more detail about what's going on? I
can't believe the PIN is going out as DTMF; but even if it's going out
as control data, can it be any harder to snoop and spoof than the ESN?

So, is the PIN check is implemented in the phone itself? Or does my
new flip phone implement PGP? :)


Thanks,

Rick S.

Us New Yorkers do have to deal with this. Recently got a phone bill
with $230 worth of calls, all to the Bronx and Brooklyn. NYNEX was
polite enough to remove the charges (though, amusingly, I did keep the
$2 volume discount that the calls made me eligible for - go figure!)

NYNEX requires owners of phones that have been cloned to use a PIN
code to complete all chargeable calls, or have the phone number
changed. I imagine it will be only a few months until the number of
PIN-equipped phones is large enough to make it worthwhile for the
criminals to invest in the additional hardware to pick them up, so
this is probably just a stopgap measure.

Take a look at a VODAVI system.  Nice, small, flexible key assignments
and can expand if needed.

Let me know if you can't find a rep.

ICV Corporation of Salem, NH., makes a 2-CO line/6-extension PBX; the
dealer price is $349.00. It works with POTS stuff so you won't need to
buy custom phonesets. They have larger systems as well.

 Oklahoma will soon joine the list of states in which one must
dial all long-distance calls the same way no matter whether the number
being called is in the same area code or not.  For about six months,
it has been possible to dial either way, but the change becomes
official on January 1, 1995.

Where are you located?   Why don't you just get foreign exchange 
service?

If they are only 15 miles apart, an FX line may be cheaper than a
leased line and there is no equipment necessary.

DEC has a big European presence and ISDN is widespread in Europe.
