The telco-supplied protection is designed to prevent life-threatening situations into the premises, and wiring threatening surges from propagating back to the network. 'Minor' excesses, can easily 'fry' many types of CPE without triggering the "life-saving" gear. > Not every subscriber has a demarc box. Every installation does have a DEMARC.

Residents do not have access to that junction box. I'm willing to bet that there are "circuit protective" devices inside that box. They may be as simple as passing bare wire "close" to a ground bus, so that a life-threatening surge/spike will jump the gap and short to ground. > For 99% of the residents not having a demarc is not an issue. I repeat, -every- customer circuit has a DEMARC. It always exists, because it is defined by statute and utility commission rules/regulations. Whether or not there is a 'box' there -- with, or without a customer- accessible test-point -- is irrelevant to the existence of the DEMARC. [Moderator snip]

Subject: Comcast bumps up speed for home-Internet users Message-ID: <4DA71812.email@example.com> By Jon Swartz, USA TODAY, April 14, 2011 SAN FRANCISCO - Home Internet users' need for speed is about to get a major rush. Comcast on Thursday is expected to announce a new, blur-fast residential service, called Extreme 105, available to consumers in more than 40 million homes in San Francisco, Seattle, Denver, Chicago, Boston, Philadelphia, Washington, D.C., and Miami, among others. The service delivers data at 105 megabits per second - more than 60 times faster than a T-1 line, which most businesses rely on, Comcast says. http://tinyurl.com/6k4tgy6 Neal McLain

I have always found it to be an "apples to oranges" comparison, because most businesses that I know who have a T1 use it for phone service - as it was intended. Some companies have a dynamic data service T1 or similar connection type that is also used for internet access, but that is usually part of a hosted VoIP package intended to replace centrex. And just to be a total semantic PITA [something I do often], bitrate is not the same thing as speed: Speed is a measure of how long it takes to get from point A to point B, which is quantified as latency. Latency in packet networks is measured in milliseconds, whereas on a T1 or other SDH pipe it is measured in microseconds. That said, it is true that virtually everyone uses the term "fast" to mean "high bitrate," so Comcast is only speaking the language of the land, and one can't fault them for that. However, it would make more sense to compare their new offering to similar offerings in urban and suburban areas from other providers, such as metro ethernet service at 100 Mbps. In some urban areas, the big telecom players are rolling out metro ethernet offerings at even higher bitrates than that. Jim ************************************************** Speaking from a secure undisclosed location. ***** Moderator's Note ***** At least in this state, many companies go to a Competive Local Exchange Carrier (CLEC), and order a "T1" line for both their phone circuits and for data. It seems there is a "tariff niche" which specifies a discounted rate for T1 lines whenever they are used for voice traffic, so those companies get data connections at a fraction of the rate that would be charged for T1 circuits if they were used only for data.

Message-ID: <firstname.lastname@example.org> Do Cellphones Cause Brain Cancer? By SIDDHARTHA MUKHERJEE April 13, 2011 On Jan. 21, 1993, the television talk-show host Larry King featured an unexpected guest on his program. It was the evening after Inauguration Day in Washington, and the television audience tuned in expecting political commentary. But King turned, instead, to a young man from Florida, David Reynard, who had filed a tort claim against the cellphone manufacturer NEC and the carrier GTE Mobilnet, claiming that radiation from their phones caused or accelerated the growth of a brain tumor in his wife. "The tumor was exactly in the pattern of the antenna," Reynard told King. In 1989, Susan Elen Reynard, then 31, was told she had a malignant astrocytoma, a brain cancer that occurs in about 6,000 adults in America each year. To David Reynard, the shape and size of Susan's tumor - a hazy line swerving from the left side of her midbrain to the hindbrain - uncannily resembled a malignant shadow of the phone (but tumors, like clouds, can assume the shapes of our imaginations). Suzy, as she was known, held her phone at precisely that angle against her left ear, her husband said. Reynard underwent surgery for her cancer but to little effect. She died in 1992, just short of her 34th birthday. David was convinced that high doses of radiation from the cellphone was the cause. Reynard v. NEC - the first tort suit in the United States to claim a link between phone radiation and brain cancer - illustrated one of the most complex conceptual problems in cancer epidemiology. In principle, a risk factor and cancer can intersect in three ways. The first is arguably the simplest. When a rare form of cancer is associated with a rare exposure, the link between the risk and the cancer stands out starkly. The juxtaposition of the rare on the rare is like a statistical lunar eclipse, and the association can often be discerned accurately by observation alone. The discipline of cancer epidemiology originated in one such a confluence: in 1775, a London surgeon, Sir Percivall Pott, discovered that scrotal cancer was much more common in chimney sweeps than in the general population. The link between an unusual malignancy and an uncommon profession was so striking that Pott did not even need statistics to prove the association. Pott thus discovered one of the first clear links between an environmental substance - a "carcinogen" - and a particular subtype of cancer. The opposite phenomenon occurs when a common exposure is associated with a common form of cancer: the association, rather than popping out, disappears into the background, like white noise. This peculiar form of a statistical vanishing act occurred famously with tobacco smoking and lung cancer. In the mid-1930s, smoking was becoming so common and lung cancer so prevalent that it was often impossible to definitively discern a statistical link between the two. Researchers wondered whether the intersection of the two phenomena was causal or accidental. Asked about the strikingly concomitant increases in lung cancer and smoking rates in the 1930s, Evarts Graham, a surgeon, countered dismissively that "the sale of nylon stockings" had also increased. Tobacco thus became the nylon stockings of cancer epidemiology - invisible as a carcinogen to many researchers, until it was later identified as a major cause of cancer through careful clinical studies in the 1950s and 1960s. But the most complex and most publicly contentious intersection between a risk factor and cancer often occurs in the third instance, when a common exposure is associated with a rare form of cancer. This is cancer epidemiology's toughest conundrum. The rarity of the cancer provokes a desperate and often corrosive search for a cause ("why, of all people, did I get an astrocytoma?" Susan Reynard must have asked herself). And when patients with brain tumors happen to share a common exposure - in this case, cellphones - the line between cause and coincidence begins to blur. The association does not stand out nor does it disappear into statistical white noise. Instead, it remains suspended, like some sort of peculiar optical illusion that is blurry to some and all too clear to others. (A similarly corrosive intersection of a rare illness, a common exposure and the desperate search for a cause occurred recently in the saga of autism and vaccination. Vaccines are nearly universal, and autism is relatively rare - and many parents, searching to explain why their children became autistic, lunged toward a common culprit: childhood vaccination. An avalanche of panic ensued. It took years of carefully performed clinical trials to finally disprove the link.) The Florida Circuit Court that heard Reynard v. NEC was quick to discern these complexities. It empathized with David Reynard's search for a tangible cause for his wife's cancer. But it acknowledged that too little was known about such cases; "the uncertainty of the evidence . . . the speculative scientific hypotheses and [incomplete] epidemiological studies" made it impossible to untangle cause from coincidence. David Reynard's claim was rejected in the spring of 1995, three years after it was originally filed. What was needed, the court said, was much deeper and more comprehensive knowledge about cellphones, brain cancer and of the possible intersection of the two. Allow, then, a thought experiment: what if Susan Reynard was given a diagnosis of astrocytoma in 2011 - but this time, we armed her with the most omniscient of lawyers, the most cutting-edge epidemiological information, the most powerful scientific evidence? Nineteen years and several billion cellphone users later, if Reynard were to reappear in court, what would we now know about a possible link between cellphones and her cancer? To answer these questions, we need to begin with a more fundamental question: How do we know that anything causes cancer? ... http://www.nytimes.com/2011/04/17/magazine/mag-17cellphones-t.html

Seeing as there is a general call to prayer five times a day in Islam, it could be useful for that. Also for local 'break the fast' times during Ramadan. Another 'App' could, using GPS and other technological cues, point the user in the direction of Mecca for those prayers (an app that could also be useful to the Jewish crowd for prayers that require the user to face Jerusalem). -- ___________________________________________ ____ Regards, | |\ ____ | | | | |\ Michael G.
