Re: Communications Question -- MIDRANGE-L

Chuck - verify in the phone closet the telco has what looks like a little
controller
box, with usually green & red lights. It's powered also, and drops the
signal
if power out.
I usually get the phone & electric guys together, and make sure you have UPS
to everything powered in the phone closet (and don't assume there is only
one
closet- start where the cable hits the building!) It doesn't take much UPS
to cover the telco equipment. This plus your dumb tube should do it.
