I am trying to learn more about using FM subcarrier technology to
deliver data.  What equipment is involved?  What does it cost?  What
(if any) regulations govern its use?

Any help appreciated.

If you have a direct phone line between two points (no dialtones)
what type of modems can you use for communications?  How will the
modems establish a connection without dialing or even a dialtone? Also
what is synchronous mode for modems? I have two US ROBOTICS SPORTSTER
14.4ks.


Thanks.


[TELECOM Digest Editor's Note: It depends on how the phone line
responds.
If it is the kind of line where when the phone on one end is taken off
hook the phone on the other end rings automatically (this is *not* a
one-number speed dial type of thing; it is done in the central office)
then the modems will work the same as always. The modem on either end
is taken off hook with ATO. Period. That's all you enter. That 'phone'
going off hook signals the central office to ring the other end and
the distant modem responds in the usual way.   PAT]

Someone told me that cellular telephones have antenna radiation
danger, being in such close proximity to the brain.  Is there any
discussion or literature regarding such claims, or can they all be
immediately dismissed as garbage?


Thanks,

[TELECOM Digest Editor's Note: There has been discussion of this topic
here in these very columns in the past. Generally speaking, it is a
non-issue. It takes a lot more power than a cellphone antenna can
radiate before it matters. If John Higdon sees this, he may well
decide
to respond. He did so the last time this topic arose here. He has
worked
around RF radiation for years, and lots of it at that.   PAT]

Ameritech tells me that they cannot roll over a trunk hunt where
instead of starting with line one and picking the first free one, it
always takes the next one after the last used one (ie, a circular
hunt).  Maybe I didn't use the right terminology.  Does anyone know
why they couldn't do this?

Hi netters,

I need urgently as much as possible informations about Metropolitan
Area
Networks in USA. The more important questions are:

1. What is the architecture of MAN (physical layer - FDDI, B-ISDN;
protocols)
2. Do banks participate and use MAN? In which way?
3. What type of network services are most popular?
4. Who is the main investor?
5. What level of data security is provided?


Thanks in advance.

I have acquired several AT&T model 510D operator terminals.  These are
'pc-like' units with touch screens.

I need a service manual (complete with diagrams and service access).

I am willing to pay for one or more of these manuals.

If you have any of these, please email me at [e-mail] or
respond to this posting.

Any information will be helpful!
