Message-ID: <4A1252C0.1000700@cybertheque.org> Today I found a 500D set with G1 handset (not retractile), and all [the] parts have matching date codes in 1953, and there is no vermilion paint or painted-over stenciling on the base. The dial also has a clear plastic cap that completely covers the hub and under which is the number card. The all-bakelite handset and the phone's robust construction make it the heaviest 500 that I have ever held. How common are early 500s with all-original parts?

Wouldn't summer time have a lot more Reverse-cycle air conditioners running that would change the power factor requirements by adding a lot more inductive load to the grid?

The caps in most motors are starting-only; only a few motors are "cap start/cap run" and those are usually bigger. So the normal grid load is always inductive. [The starting cap in an induction motor creates a 90 deg phase shift so that the starting and running windings give the one-two umph to get the motor going.] Yes, ConEd would have to add cap banks to improve the PF. (I see them on PEPCO poles all the time.) On industrial accounts, utilities often nick you a "bad PF" surcharge. I've speced and installed cap banks at pump stations for that reason. -- A host is a host from coast to coast.................wb8foz@nrk.com & no one will talk to a host that's close........[v].(301) 56-LINUX Unless the host (that isn't close).........................pob 1433 is busy, hung or dead....................................20915-1433 ------------------------------ Date: Tue, 19 May 2009 15:56:38 -0700 From: Richard <rng@richbonnie.com> To: redacted@invalid.telecom.csail.mit.edu Subject: Re: CO backup power Message-ID: <gud615h52d03ng9l6rulaa6r8t1p4litbq@4ax.com> On Tue, 19 May 2009 11:35:33 -0400 (EDT), our moderator wrote: >***** Moderator's Note ***** > >OK,I'm thick, so bear with me: I though air conditioners, or any AC >motor for that matter, had capacitors in them to help them start, and >I don't understand why they would be an inductive load. The capacitor is only used during starting. Once sufficient speed is reached, a switch operated by centrifugal force opens the starting winding. Thereafter, the load is inductive. >Plus, how could Con Ed compensate for an inductive load? Wouldn't it >take gargantuan capacitors on every pole, Yes. I see them mounted on the poles. ------------------------------ Date: Tue, 19 May 2009 07:48:34 -0700 (PDT) From: hancock4@bbs.cpcn.com To: redacted@invalid.telecom.csail.mit.edu Subject: Re: Verizon selling off phone lines Message-ID: <69fc08f3-14af-4653-bb2c-6a853f1d6f07@u10g2000vbd.googlegroups.com> On May 18, 7:09 pm, Fred Goldstein <fgoldstein.SeeSigSpamb...@wn2.wn.net> wrote: > Panel offices had a bit of what might be considered common control; > it used a "decoder" to route calls baed on the first three digits > dialed.   I would say more than a "bit" of common control; it was a common control system. The caller's desired number was stored, translated, and outpulsed to the appropriate switches. In classic step-by-step, the caller's dialing directly controlled each switch and nothing was stored. As mentioned, later on 'front-ends' were added to SxS to store numbers. In panel, the desired exchange was translated per trunking requirements. The key feature of common control (panel, crossbar, or ESS) was that an expensive front end translated the number and controlled the subsequent switching, and this front end was only used to set up the call. Once the call was set up the front end dropped out and was available for other calls. It wasn't until the 1960s that they could get the front-end to be simple and cheap enough for low-use systems (such as PBX's and small offices): before that step-by-step was the cheapest approach. The advantages of panel was that it could handle complex trunking to other offices, automated manual office interface, and a higher call load since it could support more banks than a 10x10 stepper switch could work with. Panel also included sophisticated testing gear. ------------------------------ Date: Tue, 19 May 2009 16:35:14 -0700 From: "John Meissen" <john@meissen.org> To: redacted@invalid.telecom.csail.mit.edu Subject: NC votes to end telephone regulation Message-ID: <20090519233514.363FB340D0@john> I don't recall seeing this here yet. http://www.cnbc.com/id/30745434 "The [North Carolina] House on Wednesday voted 102-11 to allow 16 providers that cover the state to cut loose from state Utilities Commission conditions setting the rates, terms, and quality of their landline services." The same old, tired arguments.. no longer monopolies, consumers benefit from competition, etc. "It's not possible for consumers to get the full benefit of a competitive marketplace when that marketplace is impacted by rules that were in place to regulate a monopoly industry that no longer exists," Clifton Metcalf, a spokesman for AT&T, said. Right. Anybody want to buy a bridge? ***** Moderator's Note ***** Actually, one could make a case for the removal of government regulation by saying that it's obviously ineffective, and clearly corrupt, and that it's best for consumers of telecommunications services to know that they're on their own and can't expect any help from Uncle Sam.

When I was with the AG's office we had a run of fiber about 600 yards long running through a then Narragansett Electric conduit on South Main St. It connected the judiciary with the AG's office. ------------------------------ Date: Tue, 19 May 2009 22:47:24 -0500 From: Neal McLain <nmclain@annsgarden.com> To: redacted@invalid.telecom.csail.mit.edu Subject: Re: Verizon selling off phone lines Message-ID: <4A137D4C.5090004@annsgarden.com> David Clayton <dcstar@myrealbox.com> wrote: > Do US telcos get any "freebie" use of public space for > their infrastructure, or do they have to pay market rates > (like land for their COs)? I can't speak for telcos, but I'll try to answer on behalf of the cable TV industry, which now offers telephone service. In all states, US cable TV companies are usually required to pay franchise fees based on revenue derived from the provision of video services and certain services incidental to the provision of video services (e.g., equipment rental, ad commissions); however, they are exempt from paying franchise fees on revenue derived from the provision of internet access ("cable modem") service or telephone service. These fees constitute payment for the right to place facilities on public (locally-owned) rights-of-way. Franchise fees are assessed by local franchising authorities (LFAs). http://www.dps.state.ny.us/frfee.htm In some states, cable TV companies are required to pay Real Property Taxes on physical plant. These fees are constitute payment for the right to place facilities on public (state-owned) rights-of-way. In most jurisdictions, cable TV companies are required to pay property taxes on owned real estate (land and buildings). These are taxes of general applicability, unrelated to the provision of cable TV service; they are based solely on the assessed valuation of the property. Cable systems owned by non-profit corporations are generally exempt from taxes. They may or may not be exempt from franchise fees, depending on the language in the franchise document itself. Cable systems owned by government agencies are generally exempt from all taxes and fees.
