You and I are defining DS0 in the same way. I don't know the
specifics of the particular line, I've only been told that it's
availible for use if I can use it. As I mentioned in another
newsgroup, this is a low-priority project, almost a spare-time
activity. I will investigate the characteristics of the line in the
next few days. Thanks for your questions. Some further info:

The radio is a Kenwood TK-720. Today we mulled the possibility of
breaking the line at the KMC-18 DTMF mic input, and multiplexing voice
and a PTT tone onto our transmission line up to the relocated base.
The drawback is that we won't be able to change channels, but we can
live with that. We only use two, and we have interesting plans for
remote access to the other channel (mwahahahaha!). I've also been
looking at some turn-key solutions from online companies, but that
would require budget begging, and it would be neat if we can do this
as an in-house, shoe-string project.

(Just for clarity, I've started the process for asking for a change on
the license, although we won't be done with this for some time. Also,
I have a class 2 FCC license, so I'm allowed to play with the XMTR ;-)

I'll post again after I've had a chance to investigate our Cisco
network that supplies the now-empty DS0 line to the top of the hill.
Thanks again for your input.
