It is circulated anywhere there is email, in addition to various telecom forums on a variety of public service systems and networks including Compuserve and America On Line. It is also gatewayed to Usenet where it appears as the moderated newsgroup 'comp.dcom.telecom'. Subscriptions are available to qualified organizations and individual readers.

I found out when someone using the SEARCH command of the Email Information Service contacted me to say they were getting quite screwey answers in response to some searches he was making ... It was only announced yesterday, so most of you probably have not yet picked up a copy, and in all probability most of you will not want to bother keeping this humongous, 26,000 (yes twenty six thousand) line file at your site. But if you did take a copy prior to Wednesday at about 6:30 PM CST, do me a favor ... ditch it and go get another copy, one that has been corrected. What this is -- when it works correctly, as it is now -- is a complete index of the titles of articles which have been in the Digest for the past six years and the author names. You can either use SEARCH, which is a command in the email server, or you can simply go and pull the two files back to your site. There are two editions. One covers the years 1989-1991 and the other covers 1992-1994. Together, they constitute about 48,000 entries, the number of messages seen here over the past six years. They are sorted in strict alphabetical order by subject with any instances of 'Re:' where it appears ignored for the purpose of the sort. Where more than one article appears with the identical subject title, the sort continues further by author *first* name. When using grep or SEARCH (which is just a version of grep I put in the email server) you can search by subject name or author name. It is highly recommended that you use the most liberal grep possible, that is, with '-i' as the argument, so that case will be ignored. Also, if you choose to search by author, search the *last name only* since sometimes the first name appears as just an initial, i.e. P.Townson. If you are really interested, use the INFO command in the email server to get two other files you'll need to interpret the rest of the data shown in the accelerated index: INFO back-issues INFO search-hints Anyway, that's enough on the topic. I botched it, and I've repaired it, I think. I'm sure someone will tell me if that's not correct. ----------------- In other administrivia news: I've received a suggestion from a reader about having a 'human resources' section in the archives. This would be a place where anyone who wished to do so could put a paragraph or two about themselves for the benefit of other readers. It would be voluntary and would have no connection at all to the mailing list, which is never shared or revealed. Suggestions for things to include would be in addition to your name, address, phone number and company/school/institutional affiliation, perhaps a .signature file, a paragraph about your current project(s), prior accomplishments, etc. It would be removed/destroyed from the archives whenever you said to do so, or modified as required. *DO NOT SEND ENTRIES NOW* Just let me know what you think of the idea, and if you would want to have data about yourself there in the Telecom Archives. Should it be open and available to all to read? I can fix it so that it is blocked or denied to FTP/Gopher users while available on a passworded basis to email service users. If it is open to all to read you can be sure of receiving lots of junk mail ... :) If on a passworded basis, then only those who contribute entries of their own would get the password to read the biographies of the others ... in other words, give a biography of yourself, and read the others. Let me have your thoughts. *DO NOT SEND ENTRIES NOW*.

I have also prepared a WWW home page for ISLIP'95. Check out the URL: http://krakatoa.mpce.mq.edu.au/~mehmet/islip95.html A PostScript version of the call for papers can be obtained from the above page as well as a LaTeX version. Cheers, Mehmet ------------------------- Call for Papers ISLIP'95 The Eigth International Symposium on Languages for Intensional Programming May 3-5, 1995, Macquarie University, Sydney, NSW, Australia Objectives There is a growing interest in computational models and/or programming languages and systems based on intensional logics such as temporal logic, interval logic, modal and intuitionistic logics. In fact, a whole new programming model called intensional programming has been created with applications in a wide range of areas including parallel programming, dataflow computation, temporal reasoning, scientific computation, real-time programming, temporal databases, spreadsheets, attribute grammars, and hardware synthesis. This symposium aims at bringing together researchers working in all aspects of this area, and to promote intensive discussions and foster collaboration among researchers. We encourage papers dealing with the theoretical foundations, design, implementation and prototype development issues, comparative studies, and applications, as well as those describing new challenges arising out of applications. The symposium will include, but will not be limited to, the following topics of interest (as they relate to intensional programming): Programming paradigms Semantics * dataflow computation * non-determinism * connectionist models * extended Kahn principle * logic programming * intensional concepts * real-time programming * termination issues * languages such as Lucid and GLU Software Engineering Applications * version control * signal processing * visual user interfaces * image processing * parallel programming * hardware synthesis * fault-tolerant systems * graphics * program verification * data models Submissions You are invited to submit either a full paper or an extended abstract of approximately 5000 words (10-15 double spaced pages). The cover page should include the name, phone/fax numbers and e-mail addres of the contact author(s), a short abstract, topic(s) and a list of keywords. Papers will be reviewed by the program committee for their originality, correctness, significance, and relevance to the symposium. We prefer PostScript or self-contained LaTeX submissions via electronic mail to either one of the e-mail addresses below. You can also send 3 hardcopies of your submission to one of the following addresses (chosen with respect to geographical proximity). Submissions should arrive no later than February 15, 1995.

I can understand software > writers of exchange manufacturers that block such a setup in their > code :-). This isn't quite true. With all circular hunt trunk groups I know of, the decision of whether or not to route advance to the next group is done each time a call origination is received. So if a trunk in the primary group is free at the time, it will get the next call. Circular hunt on primary high-alternate use combination does provide signficant benefits, especially if per trunk signaling is used. Circular hunt, if designed to always start hunting at the trunk following the one just picked, significantly decreases the impact of killer trunks on traffic capacity of the trunk group.

FYI The local cableco here in Fairfax County, VA (Media General Cable) has a 10XXXX code (106-500), used for ordering Pay-Per-View movies. I can't seem to get an answer from Bell Atlantic on how this was arranged. Is this a common practice, I wonder.
