Basic Internet concepts are covered without going overboard. Many books mention RFCs (Request For Comment documents), but few present information on how to get them (and which ones to get) in as simple and useful a form. The definition of client/server isn't accurate (it doesn't work for X, for example), but is good enough to be getting on with. IBM wants, of course, to promote its own Internet Connection Service as the Internet provider of choice, and the setup to ICS is the simpler of the two. They may, however, have taken simplicity a bit too far. If the book is correct, there is no provision for a modem initialization string. The directions for the use of other access providers is quite clear, but it states that the IP address assigned to the user is "required." This would create difficulty for providers that use dynamic allocation. The script language for automated calling is not described, although sample scripts appear to be provided in Appendix B. The description of the various applications (Gopher, World Wide Web, email, news, telnet, and ftp) is basically limited to explanations of the interface, although organized in a functional style. Ironically, one of the few exceptions to the "just the interface" tutorial recommends the use of "block files" (apparently directly analogous to the more common kill files) as providing censorship for those with children. There is no indication of any means to prevent said children from removing this "protection." copyright Robert M. Slade, 1995 BKOS2WIC.RVW 950615.

Send a one page fax with data (data also gets tested and folks who send blank pages are not getting all the information they could). It would be nice, but not necessary, if you put your name and e-mail address on the page so we can contact you if you have questions. It is so hard to sort blank pages to find yours! You will receive a short report with major errors, if any, pointed out. To try this: Fax a page to: (510) 828-5617. Wait 10 seconds (overseas no wait necessary) Poll (510) 828-5617. If you don't get the correct report, E-mail mrehmus@grayfax.com and we'll try to find your report. Blank pages excepted. The way this works is that we receive the call, then analyze it after the call is completed and make it available for the next Polling call. This can have problems but we cannot think of another way to accomplish this automatically without the possibility of other errors creeping in or without greatly increasing the expense and engineering time consumption.

The USENET and the Internet both are fascinating things themselves, but are also meta-fascinating as various pundits analyze them as though they were something else already known. Is it a telephone network? A mail system? A newspaper? A library? PAT suggests USENET is like radio spectrum in his last effort, and recently like CB radio in the seventies. However, the important differences are overwhelming. 1) you can always start a new newsgroup ... there are around 5,000 available to most people now. Compared to 40 (?) CB channels with no new ones in sight. And the USENET channels are very different from each other, based on name/subject matter. Many of us are happy with the groups we read ... alt.dcom.telecom and alt.cellular.technology in my case are fine. Very little SPAM or noise, no forged cancels, etc. 2) USENET can be changed. That cancels are so easily forgeable is just the way the news protocols have been defined. Almost without doubt, these protocols will be enhanced and USENET will survive. "Death of the USENET predicted, news at 11" is one of the quintessential self-referential cliches of the USENET which give it its unique charm. "Secure News" or SNEWS is the buzzword for the next ·_ generation. With CB, there wasn't much chance of changing broadcast or reception protocols to protect against the "Spam" PAT described, so it was CB itself which died. Of course, PAT must not be faulted for his attempt at "The USENET is a phone group. No, the USENET is a magazine. No, the USENET is a soapbox. No, the USENET is CB Radio." The USENET is new, and we don't have a consensus on how or even whether it should be regulated. The USENET has problems. We are being assaulted by the psychotic/commercial interests of scientology, and the "for your own good with a gun" interests of congress. We BETTER start comparing USENET to something, hopefully something which is protected from interference, so we can buffalo the g-men into protecting it for us, from themselves and others. (Is g-man for government-man or gun-man?) But really, cancel forgeries need to get fixed in the software, not in terms of getting people to behave differently. And the new software is being debated and developed, even as we continue to exist in our warm fantasy of free, non-commercial speech. IMHO of course, as always.

Right now we have about 240 phone lines coming in, but can't get any more until US West decides where to drop a pair gaining switch into our premises. Up until this point they were content with dropping us copper, (in fact, that was their only solution, they don't mux out T-1's anymore, or anything), but now that all distribution pairs in the street are used up, they don't know what to do. We've been pushing on them for us needed a large number of phone lines since last year when we moved into this building, and we've been putting in large orders scheduled out two or three months in advance, and then cutting them back the day before they are scheduled to what we needed at that point, but until they ran out of wires in the street, they did nothing to plan out. The pair gain switch is scaring me, since all lines are data lines, and I've seen other installations where you can't get full speed out of 28.8 v.34 modems going through an SLC. Typically getting 24k or 26.4k connections max. I've been waiting now for two months on my last line order with still no lines in sight for them to drop. (Also having problems getting DDS lines as well, I have no idea where they think they are going to be getting T-1's to pair gain off of). What are my options? (I am already considered buying a channel bank, but that seems to be extreme, just to work around US West's problems) to get US West to deliver on lines? The tarrif states that they have to get us lines, but doesn't specify a time frame.

Caller-ID was recently made available to most of Rhode Island but here are some problems with it: a) It's calling number and date/time delivery only. Duh - I don't need time/date but the name would be nice. Good going Nynex! b) A call from an associate in MA shows as OUT OF AREA. I called my long distance provider (who is also the friend's LD provider) and they've verified that their network will indeed pass Caller-ID information along. I call Nynex and ask them what the deal is. Turns out, according to some droid that Nynex "Doesn't have the technology to do that.". I wish Mary Alice Williams would stop talking about "Nynex Now!" and start talking about the real problems with what I propose is the worst telephone company around other than GTE.

Bo-doo-weep tones 2. Harsh noise for about ten seconds 3. click then silence Curiously, the "SPKR" LED on my ATT Speakerphone then sort of FADED away slowly, but the "LINE IN USE" LED stayed on. Normally, when I get the CPC reverse polarity after a hangup on the speaker phone, the "SPKR" LED goes out followed by the "LINE IN USE" LED. Rich Szabo [TELECOM Digest Editor's Note: Here in northern Illinois, Ameritech is not yet programmed to recognize 888 as an area code. When I tried your experiments here, dialing 1+888, etc, it went to the message saying 'When calling a number inside your area code dial only the seven digits. When calling a number outside your area code dial 1 plus the area code and the seven digits.' Interestingly though, throughout the entire intercept message (and even for a couple seconds before it started) there was a constant 'clicking' noise, or perhaps 'ticking' noise at about two second intervals. The 'when calling a number' intercept message is very common; it always plays out when a one is entered before a non-working area code; but for whatever reason when 888 is selected you get that tick/click sound along with it which is not part of the recording. It sounds in a way like someone taking a phone on and off hook repeatedly at about two second intervals. PAT] ------------------------------ How can one determine whether certain numbers are within the calling area and certain numbers are not? For instance, I am in 301.294.xxxx and if i call 301.762.xxxx its a local call. If I call 202.xxx.xxxx, its also a local call, but if I call 301.428.xxxx, its a toll call. Is there any information online about how the calling areas are divided? Can one from the first six digits (npa) figure out which calling area he belongs to? Is there any logic to those numbers (sequential??? correlate to zip code?) tom [TELECOM Digest Editor's Note: Your best bet is to ask the local telco what is and is not part of your calling area. This gets very messy and could (and has) consumed much time and space here as we go round and round on the variances from one community to the next. If you ask, your local teleco will supply you with a list of all the exchanges which are considered part of your local calling area; you may assume exchanges not listed are toll calls.
