Comcast; loss of dial tone

Am looking for a wireless device (transceiver) to sit between an Alarm
Control Panel and a similar wireless device (transceiver) attached to
the output jack of a Comcast cable box.

The purpose is to take the ACP digital signals that are normally
transmitted over a land-line to a central station and, instead,
transmit them to the receiving unit attached to the telephone jack at
the rear of the Comcast cable box.

This device would solve the following problem:

	Here in the Boston MA area the trend appears that Comcast is
taking away the land-line business of residential customers from
Verizon. Comcast installers, rather than placing their cable box
(containing the dial-tone output jack) in the vicinity of the old
Verizon interface (punch-down terminals, two-binding-post black
protector ? where the outside drop meets all the red/green wires),
typically in the basement, they are taking the route of least
resistance by bringing their cable in through a 2nd floor window of a
room where the cable box is to be located.

	The customer's cordless base station is then plugged into the
output jack at the rear of the cable box, providing dial tone to all
the cordless house phones  When there is no wall jack in the room,
there is not even the opportunity to back feed dial tone to the common
junction point in the basement where the reds and greens are all in
parallel.  On those occasions when there is a wall jack in the same
room with the cable box, we can reconfigure the connections in the
basement to provide line seizure.

	Sometimes Comcast installers will get it right, rarely,
back-feeding to a wall jack, and in the basement severing the
4-conductor cable from the remaining group of reds/greens, and
reconfiguring to provide line-seizure.

	When the cable box resides in a part of the house where it is
impossible or cost-prohibitive to get dial tone to the alarm system,
and the customer does not want to pay for a cellular connection, the
alternative for the customer is to forego the monitoring of the alarm
system; hence a loss of revenue for us.

It therefore would be nice to employ some type of transceiver to ship
the alarm signals from the ACP to a similar transceiver that would
plug into the dial-tone output jack at the rear of the cable box.  It
would have to be a duplex device, as the ACP needs to receive the
kiss-off tone from the central station.  It would also be important
that we be able to access the ACP via telephone line from our office,
for remote programming.

Any ideas or work-arounds?

Thanks.  Charlie.
