Working with a client of mine, we have developed a method whereby anyone with a VRU that is direct dialable from the United States can receive the ANI of the caller, as well as the 800 number that was dialed, prior to conversing with the customer. This does NOT rely on Caller-ID, ISDN, or any other out-of-band type of signalling. It is really quite simple ... as soon as your VRU answers the ringing line, the DNIS and ANI will be outpulsed to the VRU using DTMF tones. If your VRU does not receive any digits within the first three seconds, it can provide a default prompting scenario. This would happen if someone called the VRU directly, instead of through the 800 number. For more information, please contact me at the email address listed below, or call me at 609-698-7044 X201.

Our software pages me with remotely with the CID of who called, so you can bet I was suprised when I got a call via a C&W 800 number in NY where the ANI -> CID was sent to my pager and it showed a number in Atlanta! I thought it was something wrong with the computer, or maybe that someone had paged me by mistake, but when I got down to NY and checked the CID box, it did indeed have the number from Atlanta. Further tests confirmed that ANI -> CID was indeed working again. I said "Wow! That was fast -- someone must have read the post and 'fixed' problem!". But, when I tried to get the CID from C&W in CT (where it had worked in the past), all I get is still "Out of Area :( . Also, after some testing, I noticed that the CID to NY works from most areas of the country, except for New England. You don't get ID's from Rhode Island, Mass, VT, NH, or Maine. I didn't try Canada yet, but I suspect that at the very least Quebec won't work either (it did previously). So it's working again -- sort of. Thanks to anyone at C&W who may have read my earlier posting and fixed the problem.

Baudette, MN - (218) 634-xxxx, and Rainy River, ON - (807) 852-xxxx can call each other locally. Dialing is seven digits (or at least it was the last time I looked). Baudette actually appears in the Bell Canada directory for Northwestern Ontario.

Satyanarayanan, Carnegie Mellon University Amal Shaheen, IBM Austin Marvin Theimer, Xerox PARC Rich Wolff, Bellcore A major challenge of this decade is the effective exploitation of two symbiotic technologies: portable computers and wireless networks. Harnessing these technologies will dramatically change the computing landscape. But realizing the full potential of the resulting mobile computing systems will require advances in many areas such as: hardware communications scalability power management security data access user interfaces location sensitivity The goal of this workshop is to foster exchange of ideas in mobile computing among workers in the field. Attendance will be limited to about 60 participants, based on the position papers submitted. Submissions should be fewer than five pages in length and may expose a new problem, advocate a specific solution, or report on actual experience. In addition, we will be hosting a small number of novel hardware and software exhibits relevant to mobile computing. The exhibits may be research prototypes or commercial products. Interested parties should submit technical descriptions of their exhibits. Online copies of the position papers will be made available via anonymous FTP prior to the workshop. A printed proceedings will be published after the workshop, and mailed to participants. A small number of graduate students will be granted a waiver of the registration fee. In return, these students will be required to take notes at the workshop and help put together the proceedings. Students who wish to be considered for the waiver must send in a brief description of their current research, and an explanation of how participation in the workshop is likely to help them.

Date: Fri, 4 Mar 1994 13:32:23 PST I've just started looking into the developments in fax gateways via the Internet. I know there are a number of commercial services available, and of course there are fax/modems and software available, but I'm talking about the *non-commercial* avenues available, such as the TPC project lead by Carl Malamud (of Internet Multicasting Service) and Marshall Rose (of Dover Beach Consulting, Inc.), and of course, Dr. Robert Riley's Digital Chicken experiment which covers the Toronto area. My question is this: How is this going to affect the telcos? It seems to me that as the Internet grows in popularity and use, people will be seeking options such as these, rather than mere discount fax plans. What's the scoop? Regards, Richard I. Sambolec Internet: sambolec@sfu.ca ------------------------------ From: martin@datacomm.ucc.okstate.edu (Martin McCormick) Subject: Re: Phones in the Movies Again Organization: Oklahoma State University, Stillwater, OK Date: Fri, 4 Mar 1994 19:49:48 GMT There was a movie produced in the fifties, probably patterned after "The Desperate Hours" in which a couple of thugs terrorize a Las Angeles family for a day or so. In the movie, one of the hoods modifies the radio in a car to receive the LAPD. The criminals also place several telephone calls which the police frantically try to trace. In one scene, a technician is following the call through rack after rack of steppers, hoping that the call won't be disconnected before he can follow it through. As a telecomm enthusiast, I was impressed with the technical authenticity of the film, but I don't remember its name. Before the mid sixties, the Las Angeles PD was on 1735KHZ and was often audible in Oklahoma around midnight, especially in Winter. In the scene where the telephone technician was tracing the calls, one could hear the rata-tat-tat of steppers and the zzzzip of the resetting relays when the call tore down. One of the exchange names in the trace was Dunkirk. Does this movie sound familiar to anybody? Martin McCormick WB5AGZ Stillwater, OK O.S.U.

In the movie Electric Dreams, the protonist Miles [Lenny Von Dohlen] who lives in San Francisco, California purchases an Acorn computer to help keep his schedule in order. When he's unpacking the computer, it has European two pin style 220 volt plugs. In one scene, they do have US style baseboard 110 volt outlets with adaptors for the computer's plugs. Miles accidentally spills champagne in the computer, causing it to take on an anthropomorphic personality. The computer falls in love with Miles' neighbor [Virginia Madsen] who is a cellist. At one point, Edgar the computer calls Miles' pager while he is at a concert and serenades the cellist with Tchaikowski via the pager. It is a silly movie but rather fun for computer nerds. 2. In one of the Pink Panther movies (I forget which), Clouseau [Peter Cellars] is tracking Lady Litton in Switzerland. He's playing a bell boy delivering room service to Lady Litton's room. He's trying to remain stealthy when a lightbulb pops out of a table lamp. He has to catch the flying bulb so it doesn't break, rousing Litton's attention. He tries to put the bulb back in the socket repeatedly, but it keeps flying out. The movie is probably primariliy aimed at US movie audiances, but I doubt they understand the joke since here in the US we have Mazda base bulbs, which thread into their sockets. European bulbs have bayonet type sockets (similar to over-grown automotive turn signal lamp sockets) so the gag makes sense if you understand this. The US neophyte would think the joke dumb as there's no way a screw-in bulb would pop out that way. Well, there is an error in that scene where the mechanical device that makes the bulb pop out of the socket is clearly visible in one of the takes. I remember seeing it the first time I saw the movie and wasn't in the pick-it-apart mode. There are a number of cheesey monster movies and the like where the sytle of the telephone instrument doesn't match the country there the action is supposedly taking place.

This may be a trick question, or it may be somebody at NYNEX using an old line. No commercial modem today runs above 2400 baud on the phone line. BY definition, baud is the inverse of the signaling interval; even 14.4 kbps modems only send 2400 symbols per second, but each symbol encodes six bits, so they are only 2400 baud! The data terminal interface, of course, may be serial at the higher rate. If they're not being so literal, then it's true that they traditionally treated phone lines as "voice" and thus considered 2400 the top modem rate. But today's 9600 bps modems are about as tolerant of line quality as yesteryears' 2400 bps modems; even faster speeds will usually work. They just don't _guarantee_ it. Cape Code has no electromechanical central office switches left, either; it's all modern stuff (a few 5ESS switches with a bunch of remotes, mostly). Unless they're very far from one of the wire centers, the phone on the Cape are as good as anywhere. Fred R.
