This is a very important point in the communications and information processing world. Electronics for hardware has become incredibly cheap while labor continues to go up. If an ISP were to _properly_ verify its users' identity and monitor usage to avoid abuse, it would have to expend considerable human time to do. That's very expensive. But now hardware is so cheap and powerful we don't have to worry about that stuff as much (we still should to some extent). Thus, it becomes simpler and easier, especially in the short run, to simply buy a bigger disk and pipe than truly deal with a problem. Compounding the problem is that there's no coordination or resolve. That is, even if one ISP works hard at it, he will still get flooded with spam from others, so he'll _still_ need the bigger pipe. From the birth of information processing machines software developers have always devoted considerable effort to shaving off bits and processing cycles to squeeze out as much productivity from the machine as possible. In the very beginning this effort was extremely intensive--programmers worked in assembler/machine language (the lowest level) to carefully optimize performance. Later, faster and bigger machines allowed higher level languages (eg COBOL, FORTRAN), but even then programmers still need optimization techniques. For instance, computers have several ways of doing arithmetic, and programmers used the most appropriate way for the circumstances. The wrong way would greatly increase run time. Likewise with memory-- early computer screens and reported made heavy use of coded abbreviations to save space. It is this cheap hardware that gives us unlimited long distance telephone service and very cheap wireless service. These services require massive amounts of computing power (both switches and carrier terminals), but the computers are cheap. ------------------------------ Date: Fri, 12 Jun 2009 08:45:43 -0700 From: Steven Lichter <diespammers@ikillspammers.com> To: redacted@invalid.telecom.csail.mit.edu Subject: Re: Usenet newsgroups Message-ID: <h0tt7a$9p9$1@news.eternal-september.org> Gary wrote: > "John Mayson" <john@mayson.us> wrote in message > news:6645152a0906101234v6d65271pd05488eaac666b5d@mail.gmail.com... >> I really hope USENET isn't dying.

Do you have *any* idea how much of the country now has _usage-based_billing_ for *LOCAL* calls as well as for 'long-distance' calls? Hint: in terms of 'number of lines', the figure is in the 70-80% range. [[ remainder of argument based on false premise removed ]] The issue is the length of time, _PER_CALL_PLACED_, that the appropriate 'digit decoding' gear has to be attached to the customer circuit. The shorter that time-period, the fewer instances of such gear it takes to handle a given call volume, and the *lower* the 'cost' of handling each call becomes. This applies whether the decoding gear is outboard hardware, or a 'polling' pure software routine. >In the terms above--wasteful occupancy of equipment--requiring ten >digit dialing for all calls is far more wasteful. FALSE TO FACT. How long does it take, on average, to 'pulse dial' a 7 digit number? How long does it take, on average, to 'tone dial' a 7 digit number? (the ratio of those numbers -- over 400%(!!) for manually-dialed calls -- shows how wasteful it is to use pulse dialing. include 'machine-dialed' calls, e.g. dial-out modems, fax machines, etc. and it is over _1000%_) How long does it take, on average, to 'dial' a 7 digit number? How long does it take, on average, to 'dial' a 10 digit number? [use the same form of dialing -- tone *OR* pulse -- for both timings] (the ratio of those numbers -- about 42%, regardless of the dialing method used -- shows how "wasteful" it is to use 10-digit dialing when it is not required. ) Thus, pulse-dial over tone dial is some 400+% more expensive in digit-decoder resource time requirement, while 10-digit dialing is only about about 42% more than 7-digit dialing. Thus, 10-digit vs 7-digit dialing is about _one-tenth_ the extra overhead of pulse vs tone. > That is, if the desire is to reduce equipment occupancy, then ten > digit dialing ought to be eliminated. In a great many cases it was > unnecessary and only introduced as a matter of _social policy,_ not > technical need, so as to make it easier for newcomer companies to come > in. FALSE TO FACT. The primary motivation for 10-digit dialing was to provide "parity of service" between numbers in the 'pre-existing' areacode and the new one. For businesses, this 'parity' _is_ a *BIG*DEAL* -- it has a large impact on "retaining" customers. The 'people who pay the bills', i.e. the cusomters of the phone company, raised a big stink about (in the case of overlay codes) people _within_ the same geographic area getting a 'new' number and having to dial differently to reach them at their 'old' number. Suppose a competitor opened a new office in the area, and got "their" number in the new areacode; just dialing the 'local' (7-digit) number in the same geograph area got you different companies, depending on which number you were calling from. *NOT*GOOD* from a business standpoint. Either you give the company all "their" numbers in the new area-code -- almost totally defeating the purpose of adding a new areacode; or you have to make everybody dial the same way to reach anybody/anything within the area. The only alternative to an areacode overlay is an areacode "split" -- which only makes -half- the people change their dialing pattern. Why should the half (that stayed in the old AC) get better treatment than those who were 'forced' into the new one? Plus the fact that the -next- time you split, you similarly inconvenience half the people in the (original) half that is currently being split. >Further, the requirement of ten digits introduces more chance of >subscriber error which means wasted use of equipment and subscriber >annoyance from wrong numbers. "Assume" 1 call in 10 is mis-dialed -- reality is more like 1:200-1:500, or less, but assume 1:10 for the sake of argument. That boosts the penalty for 10-digit vs 7-digit dialing (within the same method) from 42% to just over 46%, vs. the 400+% penalty for pulse dialing over tone. Wow, the 'pulse penalty' is greater than the '10-digit penalty' by only a factor of 9:1 instead of 10:1. Factor in the share of calls that are placed by various kinds of 'auto-dial' equipment (which use short tones, and minimal inter-digit spacing) -- things like modems, fax machine, push-button speed-dialers, etc. -- and the advantage ("on average") of DTMF over pulse dialing is up in the 7-800% range. (Auto- mation can speed up DTMF dialing more than it is possible to speed up pulse dialing. ------------------------------ Date: Fri, 12 Jun 2009 18:09:53 -0700 (PDT) From: hancock4@bbs.cpcn.com To: redacted@invalid.telecom.csail.mit.edu Subject: Re: ANI vs. Caller ID Message-ID: <a2fd25bd-a733-4394-bbd1-a6aba1447c8d@j18g2000yql.googlegroups.com> On Jun 12, 6:51 pm, Robert Bonomi <bon...@mail.r-bonomi.com> wrote: > Do you have *any* idea how much of the country now has _usage-based_billing_ > for *LOCAL* calls as well as for 'long-distance' calls?   > > Hint: in terms of 'number of lines', the figure is in the 70-80% range. You are saying 70-80% of landlines have local usage based billing? Where did you come up with that figure? What is the percentage of subscribers still using rotary service? My guess it's about 10% for residential lines, if that much, and 1% for business lines. In terms of percentage of submitted calls, it's even less. Even if there were hardware devices as you describe, the traffic of rotary calls must be extremely low. > The issue is the length of time, _PER_CALL_PLACED_, that the appropriate > 'digit decoding' gear has to be attached to the customer circuit.   AFAIK, there is no such thing _today_ as "digit decoding gear". As mentoined before, all lines must be scanned often for on-off hook status. Dial pulsing is collected as part of that scanning. No extra hardware is required. The translation from dial pulses or Touch Tone signals to whatever the switch uses internally is done by software. If there is a citation describing that modern switches have a hardware device for digit decoding, could you share it? > This applies whether the decoding gear is outboard hardware, or a 'polling' > pure software routine. Software is not "tied up" on a computer when it is waiting for input. The CPU goes on to do something else. (Interrupt handling is beyond the scope of the discussion). >   How long does it take, on average, to 'pulse dial' a 7 digit number? >   How long does it take, on average, to 'tone dial' a 7 digit number? When you visit a website, the server is not "tied up" while it waits for you to think or type in stuff. It only acts when you're finished. > FALSE TO FACT. > >   The primary motivation for 10-digit dialing was to provide "parity of >   service" between numbers in the 'pre-existing' areacode and the new >   one.  For businesses, this 'parity' _is_ a *BIG*DEAL* -- it has a large >   impact on "retaining" customers. You confirmed my statement. "Parity of service" was so that newcomer phonecos would not be at a disadvantage in attracting subscribers. Likewise, so was number portability, which also adds unnecssary load and expense to swtiching--which we all had to pay for, just to benefit newcomers. ------------------------------ Date: Fri, 12 Jun 2009 13:28:54 -0700 (PDT) From: hancock4@bbs.cpcn.com To: redacted@invalid.telecom.csail.mit.edu Subject: Re: Usenet newsgroups Message-ID: <c9cddda6-b749-4731-8ef7-14a79c3b3b37@c20g2000prh.googlegroups.com> On Jun 8, 10:12 pm, Steven Lichter <diespamm...@ikillspammers.com> wrote: > Below was posted all over the AT&T Usenet server today, what is the use > of having the service if they are dropping it, any 3rd party ones suck. I think one reason users are abandoing Usenet is the increased politics of discussions ("politicization"?). Unmoderated groups are gettings lots of off topic posts (many crossposted) in support of or in criticism of various politicians. Further, even in on-topic posts people can't seem to resist including a little dig at the party/ politician they don't like. All sides (left-wing, right-wing and nutcase-wing) do it equally. There are of course times political policy is relevant to a discussion, but now it's gotten ridiculous. The world is not gonna come to the end 'cause Obama is now president, nor would've if McCain was elected. If your pizza delivery is late today it's not Obama's fault, nor if it was late last year it's not Bush's fault; no matter how much you're convinced their meddling or lack thereof is responsible. Further, there are many decisions made by govt that would've been made _regardless_ of the party in power. Another reason is web-forums that are moderated, which seem to attract more people than Usenet. On one newsgroup I participate in, from time to time someone references a post from a moderated web forum, and I'm surprised to see that that forum has much more activity than the Usenet newsgroup. ------------------------------ TELECOM Digest is an electronic journal devoted mostly to telecom- munications topics.
