With problems, of course. What I don't have is a schematic. The phone were manufactured in 2/71 and 3/75. Both have the code "2702B" stamped on the bottom. Neither one rings -- this seems more likely to be a configuration problem than anything else, because they both have ringers (unlike much older Princess phones which needed a separate one). I just don't know what jumper to move to which terminal. One phone (the older one) is considerably stranger. It receives calls just fine, but can't place them. When you dial, it produces tones, but they don't break dial tone. My ear tells me that the tones aren't quite right -- one of the pair sounds right, but the second tone sounds consistently too high pitched. Strikes me as pretty weird. Can anyone help? chris ------------------------------ Date: 4 Jan 89 17:25:00 EDT From: Subject: Network Management Meeting in DC To: "telecom" NETWORK MANAGEMENT ROUNDTABLE Association for Computing Machinery Washington, DC Chapter Special Interest Group on Data Communications February 9, 1989, 1 to 5 P.M. SPEAKERS: John Geraghty, IBM, on Netview product Keith Young, AT&T, on Unified Network Management Local standards organizations on NM standards ABSTRACT: For a long time, network management was the forgotten part of network design, added as an afterthought to a design if at all. This has changed, and now network design protocols and standards are developed or being developed. The major products for network management today are IBM's Netview and AT&T's Unified Network Management. Both of these products and a host of others are committed to move in the same direction as the developing OSI Network Management standards. John Geraghty of IBM and Keith Young of AT&T will discuss approaches to network management. This will include views of the history of network management and some future directions. The Netview and Unified Network Management products will be used as concrete examples of currently available network management products. Other speakers will discuss the current state of OSI standards for network management. PLACE: Naval Research Laboratories, Building 222 Auditorium. From the Beltway on the Maryland side of the Wilson Bridge, take I-295 one mile north to NRL exit (Exit 1). Make right at light onto Overlook Avenue then left onto Chesapeake Street. Stop at outer guardhouse,and state where you are going. Stop at inner guardhouse and identify yourself. Carpooling advised as parking is difficult. ROUNDTABLE: Roundtables are intended to provide for a sharing of ideas between developers using a particular technology, and thus normally provide ample opportunity for questions and discussions. They are free and open to the general public; however, reservations are necessary. Please contact Bill DeKeyser at Comtek, 301-681-0825 with your full name and citizenship by noon, February 7. ------------------------------ Date: 4 JAN 89 20:13- From: DMG4449%RITVAX.BITNET@CORNELLC.ccs.cornell.edu To: TELECOM@bu-cs.bu.edu Subject: Remote Call Forwarding Manipulation Is there a relatively inexpensive device I could buy to attach to a standard RJ11 telephone line which has both 3-way, and telco call forwarding as well as the fact that there is another line in the house which would allow me to remotely control call forwarding. I would want to be able to activate, deactivate, and change the number it forwards to, but of course security is important. Does such an inexpensive beast exist???

In Evanston, depending on your prefix, 475, 328, ... you have to use one of 571...576, I'm not sure how they map. Other cities should also use the same 571...576 set. My house, say 475-9999, uses: dial 1-572-9999, hear funny tone, click phone, hear tone, hang up, it rings. You can loop here^^^^ ^^^^^ ^^^^^ ^^^^^ ^^^^^^ ^^^^ ^^^^^ ^^^^ ^^^ ^^ ^^^^^ I have my phone bell hooked up (via a Fone-Flasher (Radio Shack)) to a circle of christmas lights around my room.

This is done obviously to encourage use of the telephone at times when the network is least busy. Effective on January 1, the discount period has been expanded to include all day Sunday -- actually from 9 PM Saturday straight through until 8 AM Monday. The way this is calculated is on the number of units used to place a call; not the cost of the units themselves. A call within your local calling area here costs one unit during the day, and .6667 of a unit during the overnight (and now Sunday as well) hours. A call that costs 6 units during the day costs 2 units at night or on Sunday, etc. After a given number of units are used, there is a further reduction in the price of the units themselves. Units range in price from 3.5 cents each to 5.5 cents each, depending on the number used in a month. Obviously during discount periods you use fewer units and it takes longer to cross the threshold where the cost of the units go down. ------------------------------ Date: Tue, 3 Jan 89 23:33:30 EST From: kodak!ornitz@cs.rochester.edu (barry ornitz) To: telecom%bu-cs.bu.edu@cs.rochester.edu Subject: Re: A Tiny Tim I remember seeing a device in _QST_ magazine many years ago that might help. (QST is an amateur radio magazine published by the American Radio Relay League of Newington, CT.) This device enabled a quadraplegic to operate a ham radio by using a collection of plastic soda straws for the individual to puff into. The straws connected to sensitive pressure switches that did the actual control of the radio. These switches are quite inexpensive and are available on the surplus market. The solid-state pressure transducers would also work if an analog output were needed, or they could feed a comparator circuit. These switches could be wired in parallel with the cursor keys (with repeat) to give a mouse-like functionality. A pressure sensitivity on the order of ten to twenty inches of water should be satisfactory. Back in college, I helped make a number of modifications to radio equipment for a friend who was a semi-quadraplegic - he could move his arms but not wrists or fingers. Amateur radio opened up a new world to my friend, and I am glad to have been able to help. If the idea of using pressure switches looks promising in this application, I'll see what I can find for pressure sensors. Barry ----------------- | ___ ________ | | | / / | | Dr. Barry L.

It turns out that you can easily learn to consciously control individual muscle fibers, as long as something is hooked to them that can feed-back to you the information that they have twitched or not. This extends also to brain waves. You can learn to enhance or diminish the intensity of your own alpha and theta waves (The alpha waves are indicators of a "meditative" brain state and the thetas are indicative of a "concentrating-alert" brain state. Learning to control them can influence the degree of attentiveness you can muster to a basically boring task, such as air-traffic control, but that is a different story.) I don't know for a fact -- but surmise -- that other aspects of brain activity can be controlled consciously as well. This means that a person need have no motor control at all and can still produce consciously controlled alterations in a measurable variable. With appropriate computer support, this could be turned into a communications channel. There is even a company that markets a card and software for IBM PC's and a head-band that measures brain activity -- for use by "bio-feedback" hobbyists. I believe they advertise in BYTE -- I don't have the details handy though -- My BYTEs are at home and I am at work. With a PC, that card, and some home-brew software, one could easily have a brain-driven word processor. With some (relatively) cheap hobbyist robotics hardware and some home-brew software, it could become a manipulative prosthesis. The possibilities are endless. -- Rick Thomas uucp: {ames, cbosgd, harvard, moss, seismo}!rutgers!caip.rutgers.edu!rbthomas arpa: rbthomas@CAIP.RUTGERS.EDU ------------------------------ End of TELECOM Digest *********************
