In TELECOM Digest, V10, No. 693, Roger Clark refers to new FCC regulations concerning inside wirng rules and, in particular, refers to "the point of demarcation" between the telco's wiring and the subscriber's wiring. Does the FCC require that there be such a point of demarcation? I live in GTE country and neither I, nor my neighbors, have such a point. Does this point (which I assume is a modular jack and plug) have to be accessible without entering the subscriber's premises, or at least without passing through a locked gate or door? David G.

I am served by US West. The only feature I have in my wiring which could be called a "point of demarcation" is a small terminal block on the inside wall of my garage, covered by a neoprene boot which says "Bell System" on it. Clearly no one has been out to install a "point of demarcation" or any other wiring at my house since long before the MFJ - possibly not since Judge Greene was in law school. Remember, the "point of demarcation" was brought to us by the same brilliant legal minds who gave us the law against listening to cellular telephone transmissions, which made most of us who own TV sets criminals. In my case, that point coincides with a well-identifiable point inside my house - other people may not be so "lucky". Jeff Carroll carroll@atc.boeing.com

That's it. It's the lightning protector, provided to keep your phones from exploding if there's a hit nearby. Post-MFJ demarcation points are a somewhat bigger box with both the protector and an RJ-11 plug and socket, so in case of trouble you can unplug your inside wiring, plug in a known good phone, and tell easily if the trouble's inside or outside. As far as I can tell, every phone installation in the country is supposed to run through a protector, so it is a sensible demarc point. (Yeah, large PBX installations have an RJ-21 block for the demarc point, but we can hope that such PBXes have someone around who knows what's going on.)

Most obviously any large business, regardless of two trunks or fifty trunks has a demarc box outside. I for one, have a hundred pair demarc cable block outside my back door, but then again, most people don't run a business out of their home. As for large PBX's, would a voice mail operation with five DID trunks count as a "PBX"?? As for a "PBX" itself, what about a 555 cord board for a main answering point? I know I need an RJ21X, but how many? Will one cover the incoming DID trunks, along with business lines and the voice mail inbound directly to a"regular" house jack? Please respond as I am in a wheelchair, and can't really get out to investigate at the library/ or the library at the USWEST office in Omaha; although I have asked USWEST to send me a copy of the schematic for a 555. I know this is the ninties, but I enter messages on the computer with a software program that I have. I can jumper into the computer along with the voice mail card to provide simultaneous voice/data by using one line out for the computer and me on the other. Anyway with the electric situation that usually occurs in the Midwest during the summer or winter, I feel that a 555 cord board is "handy" to have around, since I'm not dependent on an auxilliary generator to have the power to run both computer and phone system.
