In my area Bell Atlantic preceeded Verizon and Chesapeake and Potomac Tel. Co. preceeded Bell Atlantic. Many of the homes in my neighborhood, as well as the neighborhood I lived in about 12 years ago, never had demarc boxes installed. The previous owner of my home had 2 lines. There are 2 cables that come directly from a utility pole, attach to the side of the house with standoffs, go down to the sill plate and enter the basement at the gap between the siding and the sill plate. They continue about 10 feet into the basement where each cable is connected to a separate junction block. The same large-gauge, exterior wire connects one of these blocks to a third block located about 25 feet away in another part of the basement. Each block has several cables connected to it for the different extension locations. Some of these cables are so old that they are cotton-covered. A few rooms still have the old 4 prong phone jacks. I have had a few problems with our phone wiring over the years. I have _ASKED_ Verizon to PLEASE install a demarc box on several occasions but the service techs just won't do it, instead they come into the house and "fix" the immediate problem. We have never been billed for these "fixes." I would rather have Verizon install a box, and rewire the house with modern cabling myself. Perhaps one day Verizon will install the demarc and I can go ahead with that plan -- There are no stupid questions, but there are lots of stupid answers.

No sexism involved or intended. I have no idea if it is genetics or how they are raised, but in my experience, most women are MUCH fussier about the appearance of their surroundings. The stereotypes arose for a reason. Stuff most guys would shrug over irritates some women every time they see it. It isn't that they are irrational, it is that they have different priorities. Yes, there are exceptions, but that is why they are called exceptions. -- aem sends... |

Perhaps one day Verizon will install the demarc and I can go ahead with that plan Feel free to do whatever wiring you like, WHEN you like. Just because there is no "official" SNI/D doesn't mean you can't do your own wiring. You simply begin your wiring at the point where the telco drop wire terminates - usually on a protector block. With the simple installation of a RJ11 block and short line cord, you can build your own "interface" just immediately beyond the telco's protector. If I were to completely rewire a home, I would place a dedicated "home run" to each outlet (as opposed to the "series" type of wiring) and terminate each cable to a point that is walk-up accessible on a utility room wall. From that location you simply run ONE cable to the demarc. Fumbling around in the joists, along with the darkness and spider webs, is a PITA. You can buy your own demarc box or SNID or whatever, you know. The internet is a wonderful thing. Just connect the old telco house feed to the 'protected' side of the box. -- aem sends... |

However, some folks object to PAYING for, and installing themselves, that which SHOULD (and eventually might) be installed for "free" by the telco. Just connect the old telco house feed to the 'protected' side of the box. While it sounds easy enough, keep in mind that service providers take a VERY dim view of unauthorized persons messing with THEIR property. In my experience, those that did work on the telco side of the demarc did so in a shoddy, uninformed manner. Most often the ground was omitted. Ignorant or, more likely, careless alarm system installers were most likely to work "ahead" of the demarc. In many cases, they would make their "line seizure" tap AHEAD of the protector, routing the unprotected pair to the alarm system panel, then back to the protector where it was finally protected. There is a potential, significant ADVANTAGE to NOT having an official network interface, particularly IF the customer does NOT subscribe to an inside wiring maintenance plan: In the event of inside wire trouble, where the subscriber is unable to UNPLUG from the network, a trouble isolation charge is NOT levied. It is during this isolation process that the repair tech is SUPPOSED to install a SNI/D, especially if the customer does NOT subscribe to an inside wire maintenance plan. That way, if inside trouble occurs again, the isolation charge ($) CAN be levied. On numerous occasions, I encountered and performed just as I described. I would install the interface. Then, if the trouble was on just ONE of the station wires, I would leave that one disconnected, usually restoring service to the rest of the customer's system. If there was only one pair leaving the old protector (series-wired home), the customer remained out of service until the inside trouble was cleared. In either case, I would show the customer their new SNI and demonstrate its operation. I would then explain their options for repair including an offer to fix the inside trouble myself at my company's exorbitant rate. A SNI/D (Standard Network Interface Device) does NOT necessarily improve service as it provides NO improved protection compared to the old, grandfathered "hard-wired to the protector" service. The SNI/D simply provides an OFFICIAL point of demarcation between the service provider and the customer AND a convenient means to disconnect from the network for trouble isolation purposes. -- JR |

Yeah, I know I could install a box myself, but I guess I can be just as stubborn as the phone co. I've added new wiring where the house needs it, but I'd just rather not do Verizon's job for them. -- Make it as simple as possible, but no simpler.

Jim Redelfs wrote: Ralph Mowery wrote: US standard ring voltage is 90 volts AC at 20 Hz unless you're on a party line and the ringers will be of the type that are filtered to ring at different AC frequencies. Multi-party service did NOT use "filtered ringers". I don't believe such a thing ever existed. On two-party service, the ringing current is sent down one "side" or the other of the serving pair. At the station, the phone's ringer was connected to either the ring or tip side of the pair and the other side to ground. As mentioned earlier here, most station wiring was, for DECADES, three conductor. The third conductor was to provide a ground for partyline use. A private line-wired set, "illegally" connected to a 2FR, would ring for ALL calls because its ringer was wired ACROSS the pair instead of as I described above. Really OLD, multi-party installations? That was even more complicated. A 4FR (four parties on the same cable pair): One party on the ring side What's this "pair" stuff? Back in the 50's, in West Texas, we (and everyone else not living "in town") had a wood box hung on the wall, maybe two feet high and 8-inches wide, with a stethascope-like mike in the middle, and a crank on the side. Cranking long or short gave you the long-short-short etc. Now, the "pair stuff": We were some 15 miles from town, and our "line" (well, party line) went that entire distance, and consisted not of a pair, but of a single bare wire. The other side of the pair was the ground, of course. You ALWAYS had to shout over the, uh, rice-krispy (sp?) pop crackle and snap or whatever, but LOUD, damnit, LOUD! "HELLO! HELLO! COULD YOU SAY THAT AGAIN! WHO ARE YOU CALLING? WHO IS THIS? BILL? NO? WHO THEN? BILL? TOO MUCH STATIC -- I CAN'T HEAR YOU! CALL BACK TONIGHT! LESS STATIC" "Who was that, honey?" "I don't know, couldn't get his name" etc, etc David |

I have seen telco technicians do all kinds of things in residential wiring, including using black/yellow pairs, even green/black or red/yellow, or most any other permutation, if it helps them avoid stringing a new wire at telephone co. expense. I've seen them use wire nuts or twisted wires covered with electrical tape to make their connections. Of course, when it is at the consumer's expense, then they insist on doing everything up to standards. Please don't generalize what is probably best practice to what is actually being done the field. Since the late 70s, all interior wiring belongs to the consumer. You don't get anything at telco expense anymore. I also haven't seen an interior phone wired by a real telco installer repairman in years I don't think it was in the 90's that we got that they put that little box outside the house. I *know* it wasn't the late 70's or even mid '80s here, anyway. (New Rochelle, NY, "Westchester County") either. They are usually contractors who are basically clueless. Back before the US v ATT decision if you had 2 lines, they ran 2 cables or a 25 pair if you were in an office that might get a call director phone. BSP said you did not run 2 lines in one cable without using twisted pair. David |

David Close, but no cigar. Tip and Ring are the parts of one of those 1/4 inch phone plugs they used. The plug is divided into two parts with an insulator separating them. There is the tip at the end, and the shaft portion is the "ring" Actually the plug is divided into 3 parts. The shaft is the "sleeve". The "ring" is a ring between the tip and the shaft. "Sleeve" is a 3rd wire used in the central office to determine if the line is busy. In the switchboard days, the operator could touch the tip of a patch cord to the shaft part of a jack and if they heard a click in their earphone the line was busy. On some boards it could light an adjacent bulb. "Sleeve" continued into the mechanical switching equipment, and there must be a digital equivalent in modern electronic switches. -- bud-- |

I'm told Western Electric manufactured the jacks at one plant and the mating plugs in another. This discouraged employees from taking home samples. I miss Ma Bell. |

Yes. However, local Operator service you describe was in place long before the "pair" was introduced. In smaller, local exchanges, the switchboard was often located in the parlor of a local resident's home. The Operator, usually the lady of the house, would go about her business in the home, stopping to connect calls when they rang in. She would dry her hands, proceed to the switchboard, don the "chestset" (large horn-shaped transmitter hung from the neck that rested on the sternum into which the Operator spoke) (not yet headset), and answer the call, "Number please!". Generally, the Operator went to bed at 9:00 or 10:00 PM Sunday through Thursday and stayed up an hour to two longer on Friday and Saturday night. Outside those hours, one dare not ring-up the Operator unless there was a true emergency, a baby was born, or someone had died. I always found it strange that death was treated as an emergency, as if the deceased isn't going to be dead very long. "Dad died last night but the doctor was slow getting here, so dad came back to life." :-) |
