Did you know that driving over a hose line can throw the nozzle crew around violently, damage the hose, and in extreme cases block the flow of water completely? Preventing such occurrences and reserving access for fire service operations are what fire lanes are for. The fire lane provides space for laying hose, throwing ladders, and deploying heavy stream appliances. [Unlike the average person,] the fire crew is not going to panic about being trapped until the call is over, and then drive out over the hose lines, and wrap them around the cars axle thus depriving the attack crew of water and delaying the attack on the fire. How do I know this? I've lived it. It's a lot of fun making a search in the back of a burning mercantile with the smoke banking down to knee level and having the supporting nozzle crew suddenly start yelling "We've lost our water boys - get out now." -- Tom Horne "This alternating current stuff is just a fad.

My feeling is that since they broadcast audio on 87.7 FM a few weeks ago, they should continue to be able to broadcast audio on 87.7 FM now _without_ jumping through numerous licensing hoops to be allowed to do so. Or are you saying that there's another organization chumping at the bit to broadcast FM at 87.7, and, that frequency is far enough away from others, and, usable? (Some other people suggested 87.7 actually isn't 'truly' on the FM dial being too low, but dials get it anyway.) Another poster noted radio stations aren't as valuable as they used to be. In the Philadelphia market there has been a fair amount of turnover and format changes. A few stations seemed to take in very "low-end" advertisements (semi-scams, such as miracle health supplements) That seems to me to indicate there isn't as much value to the station because they're desperate to take crappy ads. ***** Moderator's Note ***** Lisa, the FCC isn't likely to allow channel six to be used for FM broadcasting. Here's why: 1. Sauce for the Goose, Sauce for the Gander: if the former holder of the Channel Six license gets to bring in revenue from FM broadcasting, then the former holders of other channels are entitled to do it too. 2. It's true that NTSC TV stations broadcast their audio using FM, but they're only allowed to use 25 Kilohertz deviation, not the 75 KHz which is standard in the FM broadcast band. That's why when listerners tuned their FM radios to Channel Six's audio, it would always sound quieter than regular FM broadcasts: NTSC is a different system, with different design criteria, and is not suited to the transmission of high-fidelity music. ------------------------------ Date: Fri, 24 Jul 2009 15:58:07 +0000 (UTC) From: wollman@bimajority.org (Garrett Wollman) To: redacted@invalid.telecom.csail.mit.edu Subject: Re: Walter's Telephones Message-ID: <h4clmf$24e2$3@grapevine.csail.mit.edu> In article <b4b3fbf9-2dd6-41db-9c90-700d629857e1@q11g2000yqi.googlegroups.com>, <hancock4@bbs.cpcn.com> wrote: >My feeling is that since they broadcast audio on 87.7 FM a few weeks >ago, they should continue to be able to broadcast audio on 87.7 FM now >_without_ jumping through numerous licensing hoops to be allowed to do >so. > >Or are you saying that there's another organization chumping at the >bit to broadcast FM at 87.7, and, that frequency is far enough away >from others, and, usable? "chumping"? WPVI is still on channel 6. There are some experiments underway at another channel-6 station that kept its old channel, WRGB in Schenectady, to determine how compatible standard wideband FM broadcasts are with ATSC digital signals. WRGB is currently broadcasting in FM on 87.9 MHz (rather than 87.75), although observers are still trying to figure out what the FCC has actually authorized for this experiment. In major markets, there will be (broadcast television) stations that wish to operate on channel 6, assuming the FCC doesn't decide to reallocate channels 5 and 6 to radio broadcasting, as it is currently considering. -GAWollman -- Garrett A.

Why should they get any such _special_treatment_? Do you believe that -every- Television broadcast station should continue to be able to broadcast audio at the sub-carrier frequency of their old Analog license? >Or are you saying that there's another organization chumping at the >bit to broadcast FM at 87.7, and, that frequency is far enough away >from others, and, usable? (Some other people suggested 87.7 actually >isn't 'truly' on the FM dial being too low, but dials get it anyway.) That's right. it _is_ *outside* the official FM band. *NOBODY* can, or _ever_could_ get a license for an audio-only FM transmitter on that frequency. In point of actual fact the TV station didn't broadcast on _that_ frequency either. TV stations broadcast a single, _complex_, signal -- an amplitude- modulated, single-sideband, vestigial carrier signal, to be precise -- one component of which is a medium-deviation frequency-modulated 5.75 MHz 'tone'. By 'sheer coincidence' -- since -this- 'tone' (technically a "sub-carrier") is of constant amplitude -- it "looks" similar enough to a conventional broadcast band FM signal that a conventional FM receiver can extract the audio from it. There is _NO_ guarantee that -any- particular "FM broadcast band" receiver will, in actuality, be able to tune 'far enough' outside the FM broadcast band to pick up that broadcast. The -only- reason it works, _when_ it does, is 'cheap manufacturing' of the receiving devices. >***** Moderator's Note ***** > >Lisa, the FCC isn't likely to allow channel six to be used for FM >broadcasting.

And, the FCC does _not_ regulate radio use at the Newfoundland aviation facility that was the traditional starting point for trans-Atlantic flights via Thule, Greenland. Thus, no sauce for Gander.

See sections 73.207, > 73.213, and 73.215 of the FCC Rules. So, who gets their wrist slapped when that spacing is violated? :-) Here (San Francisco Bay Area, San Jose to San Francisco, Oakland, Santa Rosa), the FM stations are mostly at 0.4MHz separation but there are some commercial stations spaced at only 0.2MHz. I didn't realize that until the station I followed for 20 years just changed its playlist and I had to seek a replacement. The best list of SF Bay Area FM stations is here (sorted by frequency): http://www.sfgate.com/cgi-bin/article.cgi?f=/tvradio/media/radio_fm2.DTL And since I built an SCA decoder into one of my FM tuners, I also recently checked to see how many stations had alternate programming: a LOT. ***** Moderator's Note ***** SCA is an acronym, which stands for Subsidiary Communications Authorization: it's a system that allows FM station to "piggyback" low-quality analog signals on their regular broadcast channel, for reception only by licensees who have special receivers. It's usually used for Muzak or similar background-noise services, although I know a station in Boston which uses its SCA allocation to carry "The Physicians Network", which is a never-ending source of amusement if you listen to the ads. ------------------------------ Date: Fri, 24 Jul 2009 15:40:42 +0000 (UTC) From: wollman@bimajority.org (Garrett Wollman) To: redacted@invalid.telecom.csail.mit.edu Subject: Re: Walter's Telephones Message-ID: <h4cklq$24e2$1@grapevine.csail.mit.edu> In article <4A68FB26.8000407@thadlabs.com>, Thad Floryan <thad@thadlabs.com> wrote: >Here (San Francisco Bay Area, San Jose to San Francisco, Oakland, Santa >Rosa), the FM stations are mostly at 0.4MHz separation but there are >some commercial stations spaced at only 0.2MHz. The Bay Area is a hundred miles long from north to south, with mountain ranges on both sides providing terrain shadowing that allows closer spacing. It's not a typical radio market by any stretch. Even co-channel class-As need only be spaced 112 km apart! New York is a more typical example, with class-Bs at 92.3, 93.1, 93.9, 94.7 (Newark), 95.5, 96.3, 97.1, 97.9, 98.7, 99.5, 100.3 (Newark), 101.1, 101.9, 102.7, 103.5 (Lake Success), 104.3, 105.1, 105.9 (class B1, Newark), 106.7, and 107.5. (With the exception of the 94.7, all transmit from the Empire State Building, and most are on the master antenna there.) The second-adjacents are, for the most part, way out in the suburbs, with the exception of a few stations that are "pre-'64 short-spaced" and don't have to observe the second-adjacent spacing restrictions (which were changed in 1964 when the current system of FM classes was introduced). -GAWollman -- Garrett A.

But I stand by my underlying points: - The Channel 6 situation that Lisa described worked ONLY for analog (pre-DTV transition) broadcast stations operating on VHF Channel 6, due to the proximity of Channel 6 (82-88 MHz) to the FM broadcast band (88-108 MHz). In the Philadelphia market, that was WPVI-TV, but the same situation existed throughout the USA and Canada. - Any analog television broadcast station licensee could have applied for (and possibly have received) an FM broadcast station license for the purpose of to transmitting its audio signal in the FM band.

Actually, many of them did -- indeed, most television operations were started by radio stations, rather than the other way around. The FCC's policy in the 1970s and 1980s was to break up such combinations, so the stations in radio-TV combination could not be sold to the same buyer, and no new combinations could be created. (The same thing was true of newspaper cross-ownership, which is still being fought over in the courts, much to the detriment of both broadcast and print journalism.) >As for radios with TV tuners, are there any radios available with TV >tuners capable of tuning the audio of post-DTV transition digital TV >stations? There are expected to be some relatively soon, once the ATSC-M/H standard is implemented by stations and consumer-electronics companies. (Qualcomm MediaFLO, used for video-on-cell-phone systems by both Verizon and thenewatt, uses an incompatible system, on former channel 55.) There will be broadcasters testing transmissions to prototype handheld devices later this year -- but it's probably still going to be targeted more towards the cell-phone audience than the portable radio audience. The existing ATSC system requires too much computational heavy-lifting to be decoded by limited-battery-life portables. -GAWollman -- Garrett A.

Better would be to disable the driver's ringer (assuming this can be done). There's a BIG downside to having a phone OFF when there's a need to call 911 ASAP. My present cellphone takes about a minute or so to boot from poweroff. The things I've seen while driving along I-280 from the South Bay to points south of San Francisco daily for 15+ years are legion: hay bales in the lanes, 30-foot tree limbs straddling two lanes, sofas on the roadway, gardening gear (rakes, lawnmowers, wheelbarrows, etc.) falling off gardener trucks, Porta Pottys falling off their transports onto the road, cougars and deer acting as if they own the road, airplanes landing (twice), cars scribing DNA helixes on the roadbed before flipping and burning, even people running/walking across the lanes, etc. These are all true events -- I could write a book. :-) I've called 911 at least 50+ times over the years to report such incidences, and that usage is still permitted (in Calif.) for drivers with a cellphone. Shutting off the ringer while driving is a simple thing to do, and incoming calls go to voice mail which I can handle later. Fur the curious and for those local who may want to be wary, there are three "hot spots" I've noted along I-280 by the number of incidences: I-280 and Hwy 85, +/- 2 miles N/S of Page Mill (in Palo Alto), and California's "Mystery Spot" between Edgewood Rd and Hwy 92 (esp. given the roadway is curved and banked incorrectly). I even had my front license plate "stolen" while driving in the "Mystery Spot" -- it was ripped off by a bouncing plastic bucket (I was flanked by cars and couldn't avoid it and, fortunately, no damage to my car); that was yet another 911 call twice: once to report the items on the freeway, then again as a followup upon arriving at my office and noticing no damage, just the missing plate for which the (later mailed) CHP report is still in my glovebox. Stuff happens, and I believe calling 911 when it does has helped prevent loss of life and property. ------------------------------ Date: Fri, 24 Jul 2009 05:17:48 -0700 From: Sam Spade <sam@coldmail.com> To: redacted@invalid.telecom.csail.mit.edu Subject: Re: Cellphones and driving Message-ID: <MDham.67048$Qg6.46774@newsfe14.iad> Adam H.

The Department of Transportation statement comes after the release of federal documents obtained under pressure by consumer advocacy groups showing for the first time that federal transportation officials were aware that cell-phone use while driving caused hundreds of highway deaths annually as early as 2002. In an e-mail statement to Computerworld, a DOT spokesman said that DOT Secretary Ray LaHood "is deeply concerned that drivers are taking their focus off the road to send text messages or use the cell phone." While the statement does not urge drivers to stop driving while making calls, it adds that "distracted driving causes crashes, and we want to stress that the best way to avoid accidents is for drivers to keep their eyes and their concentration on the road when they get behind the wheel." The DOT issued the statement following the release of hundreds of pages documents from 2003 obtained under the Freedom of Information Act by two consumer advocacy groups, the Center for Auto Safety and Public Citizen. The documents were first provided to the New York Times, and also posted to the Center for Auto Safety Web site. The documents include findings in which highway safety researchers estimated in 2003 that cell phone use by drivers caused 955 fatalities and 240,000 accidents in 2002. ... http://www.computerworld.com/s/article/9135847/DOT_chief_deeply_concerned_about_dangers_of_cell_phone_use_while_driving ------------------------------ Date: Thu, 23 Jul 2009 23:01:32 -0400 From: Monty Solomon <monty@roscom.com> To: redacted@invalid.telecom.csail.mit.edu Subject: The Irksome Cellphone Industry Message-ID: <p0624088ec68ed337753f@[10.0.1.3]> State of the Art The Irksome Cellphone Industry By DAVID POGUE The New York Times July 23, 2009 Never let it be said that Congress never did anything for you. In recent weeks, the Senate Commerce Committee has been holding hearings about handset exclusivity. That's when a phone maker (like Apple) offers a particular model (like the iPhone) to a carrier (like AT&T) exclusively for a period of time (like five years). Come to think about it, that example - the iPhone - is pretty much the only one anybody cares about. These aren't handset-exclusivity hearings; they're "Why can't we have the iPhone on Verizon?" hearings. Look, it's great that our elected officials are looking out for us. The last time Congress got involved, we wound up with phone-number portability, meaning that you can keep your number when you switch phone companies. That's unequivocally a good thing. But the exclusivity point is not such a slam-dunk. Sure, everybody would love a Verizon iPhone. But there are some valid arguments against banning exclusivity deals altogether. First of all, there are two different cell network types in this country: the AT&T/T-Mobile type (called GSM) and the Sprint/Verizon type (called CDMA). Creating a Verizon iPhone isn't just a matter of signing a few papers. It requires new engineering. It takes time and resources. Second, you could argue (as some of the carriers at the hearings have) that exclusivity arrangements are actually good for innovation. Look at Visual Voicemail, which displays your voicemail list so you can get to them in any order, without being held hostage to your carrier's prompts. That's a very cool iPhone breakthrough that required Cingular (the iPhone's original carrier) to make special changes to its network - collaboration that probably wouldn't have happened if Cingular hadn't had the incentive of exclusivity. Above all, though, you've got to wonder why, if Congress has time for things like cellphone gripes, it's barking up this particular tree. Frankly, there are many other, much more whopping things that are broken, unfair and anticompetitive in the American cellphone industry.

Another "weird thing": my wife and I found a particular "el cheapo" portable DVD player model, region 1, that turned out to be so shoddily designed that: (i) only four out of six samples could play anything at all reliably, and (ii) two of those four seemingly *ignored* the DVDs' region code. We were testing Australian, European, South American, Japanese,and US DVDs (all region-coded) to see whether that portable could work as b'day present for European nieces -- answer: either of those last two instances could :-) . So: one became that b'day present, and *we* kept the other, as a most economical alternative to a (much pricier) all-regions player :-) .

It did the job, but it was too complicated: not only did it have separate supervision leads that were isolated from the talk path, but it had separate ringing leads as well. There might have been PBX's or other CPE which could access the CDH directly, but ordinary key equipment could not: to use it for CPE key equipment, you needed _another_ interface to match the CDH interface. Ma Bell had too many interfaces and they cost too much to install and rent: it was inevitable that the FCC would dictate type-acceptance and allow direct connections.

In California we were spared that because the CPUC got out ahead of the FCC by establishing a certified premise equipment program.

The _most_common_ such beast was a "DAA", required, pre-carterfone, for connecting a customer-owned _modem_ to the phone line. Such devices have, for all practical purposes, disappeared from the marketplace after the FCC mandated a 'standard' isolation interface for CPE, with 'type acceptance' methodology for approving manufacturers. Type-accepted line isolation modules are available from practically any significant component manufacturer for the telecom industry. See, for example: http://www.nuhorizons.com/products/NewProducts/poq20/clare.html For _lots_ more, google for "telephone line interface IC". ------------------------------ Date: Fri, 24 Jul 2009 19:33:16 -0600 From: Reed <reedh@rmi.net> To: redacted@invalid.telecom.csail.mit.edu Subject: Re: What is this device called Message-ID: <sJqdnVYdNJn4_PfXnZ2dnUVZ_oSdnZ2d@earthlink.com> Tom Horne wrote: > There used to be a device that could be obtained from AT&T, lo these > many years ago, that would isolate non standard telephone equipment from > the PSTN and still provide ringing and talk current to the non standard > equipment.

I'm trying to devise a way to patch the PSTN incoming calls to manual switchboards that predate customer dialing. If you connect the interconnect terminals of some of those boards it will look like an off hook condition to the PSTN. -- Tom Horne "This alternating current stuff is just a fad.

Or are there some cell frequencies set aside >specifically for these emergency trucks? No one would reserve a valuable freq. for occasional use. If adding capacity, such as at the Inauguration; I'd guess they take the freq set for their site that's furthest away, and reuse it. The COW/COT likely has low-level antennas with patterns restricted to that immediate area. If replacing a down site [power, flood, tornado, etc. outage] it's straightforward; use that set. -- 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: Fri, 24 Jul 2009 11:19:19 -0400 From: Monty Solomon <monty@roscom.com> To: redacted@invalid.telecom.csail.mit.edu Subject: Mass 201 CMR 17: A Survival Guide for the Anxious Message-ID: <p06240886c68eac4253c2@[10.0.1.3]> Mass 201 CMR 17: A Survival Guide for the Anxious Security experts offer tips for navigating Mass 201 CMR 17. Will your business be ready? by Bill Brenner, Senior Editor, CSO July 23, 2009 FRAMINGHAM, Mass. -- David Escalante has as much cause as any IT security practitioner to be nervous about Mass 201 CMR 17, the tough Massachusetts data protection requirements organizations must comply with by Jan. 1, 2010. As director of computer policy and security at Boston College, he oversees the security of a computer network accessed daily by some 10,000 students who storm the campus after Labor Day with myriad personal computing devices loaded with any number of sinister programs. (See Six Essential Steps to Secure Academia.) Yet he was cool and calm during a CSO Executive Seminar on Mass 201 CMR 17.00 Thursday, as were the other legal and security experts on hand. The reason -- they're reasonably confident most companies will survive this latest compliance push unscathed. And why not? Many of the provisions are basic best practices other government regulations and industry standards have required for years. That's not to say this is a piece of cake. Compliance doesn't always ensure security. The Hannaford supermarket chain learned this the hard way after suffering a data breach despite all the PCI DSS compliance work it had done. And so the seminar speakers tried to give attendees a clearer picture of what's needed. Among the advice -- have a plan on the shelf that outlines who will do what in the event of a data breach, and invest time and money in awareness campaigns that won't put employees to sleep. "Much of this you should be doing anyway," Escalante said. "If you follow best practices such as those outlined in things like Cobit and ISO 17799, you WILL be okay." ... http://www.csoonline.com/article/497934/Mass_CMR_A_Survival_Guide_for_the_Anxious_ ***** Moderator's Note ***** I'm assuming that this is telecom related because data standards include proper management of modems.

A couple of weeks ago a at&t contractor was checking cable pairs to make sure that they match the records; we all know that there are a lot of errors; anyway he moved me over to the cable pair that his records showed, the problem was the cable he moved me to had a dead short; i.e. no phone or DSL for 4 days, they got that fixed but my speed was down really bad. They found 2 bridge taps on my cable; I guess DSL does not like those, they removed them and my speed came back up a great deal, but not what is was supposed to be. The strange thing is my ethernet connected computer is working fine. I made no changes on either setup and both were working fines before the repair from hell started. I do know that there is a little loss on wireless connections, but not 1.3 on a 6 meg link. I asked on the Mac groups, but no answers. I'm sure it has something to do with my AirPort card and the Router, but as I said no changes were made and all the setting are the same. There are other problems, like on 26 ga led cable, that AT&T plans to replace some time next year when they plan on finally offering U-Verse on my block, we are only block not to have it since our cable is over 30 years old. -- The only good spammer is a dead one!!

It is called high-frequency trading - and it is suddenly one of the most talked-about and mysterious forces in the markets. Powerful computers, some housed right next to the machines that drive marketplaces like the New York Stock Exchange, enable high-frequency traders to transmit millions of orders at lightning speed and, their detractors contend, reap billions at everyone else's expense. These systems are so fast they can outsmart or outrun other investors, humans and computers alike. And after growing in the shadows for years, they are generating lots of talk. Nearly everyone on Wall Street is wondering how hedge funds and large banks like Goldman Sachs are making so much money so soon after the financial system nearly collapsed. High-frequency trading is one answer. And when a former Goldman Sachs programmer was accused this month of stealing secret computer codes - software that a federal prosecutor said could "manipulate markets in unfair ways" - it only added to the mystery. Goldman acknowledges that it profits from high-frequency trading, but disputes that it has an unfair advantage. Yet high-frequency specialists clearly have an edge over typical traders, let alone ordinary investors. The Securities and Exchange Commission says it is examining certain aspects of the strategy. ... http://www.nytimes.com/2009/07/24/business/24trading.html ------------------------------ Date: Fri, 24 Jul 2009 18:48:49 -0700 (PDT) From: gerard <macadude@gmail.com> To: redacted@invalid.telecom.csail.mit.edu Subject: Polling switches for record information - any guidance? Message-ID: <8028968e-adcb-474f-a291-979317f7ff88@g1g2000pra.googlegroups.com> Hi, I'm developing an application that requires records from lucent and nortel switches for analysis. I am not an expert on the capabilities and functions of switches - still learning. I am wondering if there is a telnet type functionality available to the switches whereby you can connect via TCP/IP and spool the record information to an output file? Or is there a function/command you can run to create a frequent output file that can be obtained by ftp/sftp. My objective is to periodically and automatically download the switch information to analyze the results and perform further investigation on the configurations therein for validity.
