Sure! Somewhere in my basement I have a couple of KS-20721 Line Protection Devices. I can strap them up as STC's for you, too. Ohio Bell swore these were absolutely necessary to prevent the destruction of the network by non-Bell equipment ... seems like that was only a few years ago, as I recall. If these are not acceptable, I might be able to find some CDH or STP type units for you ... maybe we should hook them up in front of John Higdon's Panasonic PBX to keep it from degrading the network as we know it ... (Sorry for the sarcasm here, but it really wasn't that long ago that AT&T and the Bell Companies assured the FCC that couplers were absolutely mandatory to protect the network. And the Bells wonder why their "concerns" meet with so much skepticism these days!) Seriously, there used to be FCC approved units for this purpose around. I think they were used in answering machines extensively at one time. I recall seeing an ad for FCC registered line isolation modules for incorporation into equipment not too long ago. Macy M.
