Consequently, I'm in search of a CNID box with a computer interface. Since I'm sure there's a collection of prevailing net.wisdom on which CNID boxes are a) decent and b) can be interfaced to a computer in some fashion already summarized somewhere, if someone would be kind enough to forward me a copy of said summary I'd be most appreciative. Additional info: I'm running a 386SX Intel platform machine (MSDOS). I currently run a BigmOuth/Powerline I PC voice mail card, which I would like to augment with CNID capability. If there is another low-cost solution, such as a voice mail card with CNID capability built in, or perhaps one of the newer V.32bis modems with CNID and voice processing capabilities, I'd consider that also. NOTE: If my initial assumption is incorrect, and no summaries of this type of info exist, I'll be happy to produce a summary of responses and make them available. Thanks for your help. >From the virtual desk of...

A recent report in [Newsbytes] states that Austel (the Australian telecomminications regulatory authority) has forced Apple Australia to recall all Newtons sold in the country, for a firmware lobotomy (ie, re-programming the firmware so that it is no longer capable of generating DTMF tones). [Sorry I can't quote the actual story, but I left it at work, and if I leave it until tomorrow to post this, I'll forget.] The reason given was that the device was not submitted to Austel for approval, despite the fact that there is no electrical connection between the Newton and the telephone line, and that many unapproved DTMF diallers are for sale on the Australian market. Looks like I'd better go and get my vocal chords approved before they're recalled too :-) I intend following this up with Austel tomorrow, and will post any results I get to the Digest.

PAT] Lesseee ... why should the person who is PAYING for the call have the right to that information ... :) That's why caller blocking is available on a local level. The guy making the call is paying for the call, either with the monthly charge, or per call charges. Where I work, we're in the process of integrating Caller-ID with our phone/computer system. We have 400+ incoming T1's for voice. We use one T1 for caller-ID data for every six T1's in use. When a customer calls up, their account information will be brought up on the computer in front of the operator taking the order. If it's a previous customer, we could concevably take the order in under one minute. We're currently trying to get some forms printed up to protect us against an unauthorized person calling from someone's house and using their account. It's there and available. As a matter of fact, we have it now, but on a limited basis. If we get an "unwanted" call, we can type in the trunk number and get the ANI off of it.

I assume there were local private lines as well as inter-city trunks. Were these switched a la the early cordboards? i.e. could someone with a private line send directly to another city? Or only to the WU office? How did the WU operators switch between lines? What was the protocol for raising an operator at the other end? How did one "get in" on a busy line? Etc ... Is there a comprehensive history of the operating practices of the landline telegraph service in the US? Gabe Wiener -- gmw1@columbia.edu -- N2GPZ -- PGP on request Sound engineering, recording, and digital mastering for classical music "I am terrified at the thought that so much hideous and bad music will be put on records forever." --Sir Arthur Sullivan [Moderator's Note: The first TWX machine I recall seeing sometime in the 1950's was not a dial unit. The person at the machine went off hook and presently a message would be typed out to him on the paper saying 'here is optr may i help u?' to which the person at the machine would respond by typing the desired TWX number he wanted to connect with. If the person at the machine did not respond in a timely way the 'optr' would ring the Control-G BEL at him a few times and maybe another message line 'r u there' . Of course if 'optr' was slow to respond or took the request but then seemingly disappeared and did not either connect or give a report in a few seconds to a minute later, the clerk would do the same tactics in return -- pound the BEL key to which the central office would reply, 'optr here mom' where 'mom' = 'moment please' or 'stand by' or more rudely, 'hold your horses, I am busy and will get to you in a minute'. Or they might just type 'mom'. Western Union had an automatic gizmo for their operators to use which (from a telex you got the Western Union operator) responded with a message typed out every thirty seconds or so, 'ALL POSITIONS BY ... MOM' where 'BY' was the historic abbreviation for 'busy'. After passing the number you wanted there was no audible or written confirmation the other end was ringing, but if the other end answered the calling machine would see the typing start on the paper. Otherwise the operator would return sooner or later to type out 'nbr da' (doesn't answer), 'nbr by' (busy), 'nbr od' (machine at that end out or order) or perhaps 'sorry nc' (no circuits available now, try again later) or 'sorry nsn' (no such number, or such a number but it was a voice phone and not a TWX). There were other responses as well, two were 'wud' and 'ocd' for Western Union denies service and other Carrier denies service. Typically this meant the subscriber to Western Union telex (or other carrier's telex with whom you were asking for interconnection, like a long distance call today) had been disconn- ected for failure to pay their bill. You could also use your TWX/telex to call 'collect' if you wanted the machine on the other end to be billed for the call. You added that phrase in the opening request given to 'optr'. She would type out to the other end that it was collect and get their okay to put it through else she would get back to you with the reply 'sorry cr u pay' (charges refused, will you pay for it?).

The safety-yellow AT&T craft-access butt sets are available new, in the box with two batteries, charger and manual for $60 (how's that for pennies on the dollar, AT&T?). Well ... I broke down and bought one (ok -- I bought three). Even the standard TALK and MONITOR are swanky on this thing. The entire thing is menu driven on a 3"x3" LCD, with user input through a four-way plus button joystick and the standard 3x4 DTMF keypad. (Alpha input is via the keypad -- press 1 once for 1, twice for Q, thrice for Z, etc.) The dialed number is menu driven, or you can do it manually. MONITOR and TALK modes have digital volume access, and MONITOR has a QUIET mode for extra sensitive noise hunting. I got all that working ... The trick is these were used by AT&T folk to access the work scheduling computer system, and they have a 1200 baud Bell 212 modem and terminal program built in. But I can't seem to figure out the protocol used by the terminal program. On CONNECT, the butt-set sends tildes (~) until the remote system sends ACK, and then some five-digit something that I can't figure out; every time I enter the fifth digit, it goes back to tildes. I took the thing apart (a real trick, since it had #10 TORX screws with the security restriction post in place all the way around) and yanked the uP program EPROM. It disassembled to more than 20000 lines of 8031 (Intel MCS-51 series) assembly language. I've been able to wade througha lot of it, but isn't there an easier way? Does anyone have access to / references on the protocol used by these things? I'd hate to reprogram it from scratch; I'd like to write a small BBS for my PC that would interact with the screen, joystick and keypad using the current protocol, if I could find out what it is.

Kippenhan Jr. writes: > You asked (a couple of days ago) about the reasons for the large > number of fires in Southern California this year. The explanation given was very good, but there are a few additional factors here. First, last year's rainy season was huge, following years of drought. Brush and weeds simply shot up this spring. Now we have much more of this kind of dry fuel lying around just waiting to catch fire. Second, because we truly do live in a desert, some of the plants take interesting defense measures to keep alive. They produce a kind of volatile oil that seals in what little water they can find, and this stuff burns very well. Eucalyptus trees reportedly do the same thing, and they literally *explode* when they get hot. Finally, around this time of year we get a weather condition known as the Santa Ana winds where hot and bone-dry air from the desert blows in at very high speeds -- two weeks ago the wind was something like 50 miles an hour in my back yard. Sales of Chap-Stic (tm) have got to shoot up, because this wind is incredibly drying. Sparks happen all the time, and now the confluence of all these factors means that once a fire gets a bite, it will go on and on. All the fire chiefs know that *this* is the fire season. The first fire was started accidently started by a transient who was just trying to get warm, and it got out of hand. He is reportedly only being charged with a misdemeanor because all the officials in charge know that he didn't intend to do any of this. He is not from around here and had no idea about all of the above. Note that it gets worse. Many of the areas that burned are on hillsides and canyons, and the houses that remain are now surrounded by scorched earth instead of groundcover. The rainy season is coming around in a few months, and those poor folks are going to have a devil of a time keeping their houses out of the bottom of the canyon. This is sad news even for the "rich folks".

Unless what Sprint did caused you unfair harm (e.g. you quit your job, sold all of your stuff and moved to Idaho, and then they refused to give you your modem), the law is usually more lenient with the defendant. > monetary value (average of ten street prices for the modem initially > offered). The most you would be allowed in a case like this would be any expenses incurred because of the lack of a modem (this doesn't mean lawyer fees, research fees, your time, etc.).

I have seen that happen before only the case I saw was a 60 IPM trunk was wired to a 120 IPM audio source. That is not quite so bad as the problem you came across.
