November 1995 Newsletter of the

Front Range Unix Users Group

Old Hand Summary: 4pm Thursday November 16 ACS Rm 123 - ISDN Panel


This Month's Meeting: ISDN Panel

The November meeting of the Front Range UNIX Users Group will present a series of short talks on ISDN technology from a variety of different points of view, from the theory on how it should work, to how service providers and users are using it. We hope for this meeting to present a lot of practical information, with plenty of time for questions and answers. We have the following talks lined up:
  • Stan Bush, director of the Telecommunications Systems Laboratory at CU, will give us some background information on ISDN. He'll talk about the basic technology and the motivations to move to ISDN. He'll talk about Basic and Primary Rate (BRI, PRI), and the realities of deploying it-- including switching facilities and loop qualifications. Stan will put ISDN into perspective with future broadband technologies, and with ATM.

    Stan has a wealth of experience in telephony with Bell Labs, and has taught telephone systems at CU for the last decade. In addition to his current directorship, he is also president of Communications Technology Research, a consulting and research firm providing training seminars and consulting to a broad range of clients in the telecommunications area.

  • Tom Wilson and Ron Miller from U S WEST will discuss the differences between BRI and Primary Rate ISDN, the technical issues such as how switches are configured to support ISDN, loop qualifications, and where ISDN is supported in Colorado. They will discuss tariffs, pricing, and the directions U S WEST plans to take ISDN in the future.

  • Hank Latham, Senior Network Engineer with Colorado SuperNet will talk about CSN's experience actually using ISDN. He'll talk about SuperNet's service offerings, the equipment they're using to provide it, and how the equipment has performed for them so far. He'll talk about dealing with U S WEST over ISDN, and concerns about tariff and future deployment throughout the state. Finally, he'll talk about plans for future measured service offerings.

    Hank has a degree in EE from the University of Wyoming and has previously been employed as Network Manager at Raytheon Services, Nevada, and Network Engineer at U S WEST. Hank has really been the driving force for getting this FRUUG meeting put together, and we thank him for all of his time and effort!

  • Bill Gibson, with Niwot Networks, will discuss Tales from the Install Side: What to order, what information you need from the install, and some delightful little horror stories from our own installations of ISDN BRI and PRI lines.

    Bill Gibson has his bachelor's and master's degrees in Electrical Engineering from Stanford. Moved to Colorado in 1980 after working at Amdahl through the seventies, specializing in the console and IO channel. After designing "office of the future" with Prolink and fiber optics with Raycom, started Niwot Networks in 1988 to bring high speed communication to the PC platform.

    Niwot's first product was a T1 router for Novell Netware in 1988. Disenchanted with router performance at high data rates over long distance, Niwot focuses today on providing the maximum possible throughput between PC's and MAC's over digital data services(Sw56, ISDN(BRI), ISDN(PRI), T1 and faster leased lines).

Meeting Location

The November meeting of the Front Range UNIX Users Group will be in room 123 of the CU Academic Computing Center building at Arapahoe and Marine Streets in Boulder at 4:00 PM on Thusday November 16, 1995. Marine St intersects Arapahoe at 38th St; the Computing Center is on the southwest corner.


Last Month's Meeting

At our October meeting Dave Skinner talked about disk technologies.

Upcoming Meetings

We are working on the following potential meetings:
  • December 6: Dave Hitz from Network Appliance will be giving a talk on high-speed NFS servers.
  • January 17: Tom Cargill will introduce the JAVA programming language.

Call For Participation - JAVA

We are planning a January meeting on the Java programming language, going deeper into the details than was possible in James Gosling's talk in June. If you are using Java and would like to give a short presentation of your experience, please contact Tom Cargill at

FRUUG Library Notes

This month Addison-Wesley sends us a copy of IPng: Internet Protocol Next Generation, the protocol that is slated to allow for the continued expansion of the Internet. The book is authored by Scott Bradner and Allison Mankin, co-chairs of the Internet Engineering Task Force/IPng process.

You may check books out using your business card as your library card; you must be on the membership list to check books out. Books are due at the meeting following the one in which they are checked out.
