Telecommunications Tutorials
********************
Please visit my updated page at

********************
Purpose: This index is the starting point for a series of
tutorials that provide the basics of telecommunications.
The lessons are designed so that each
builds upon the skills learned in the previous.
Audience: These lessons are targeted to individuals with
some large system or PC/LAN experience that wish to learn more about
telecommunications. Professional telecommunications personnel may
notice that some liberties have been taken in early lessons in the
interest of simplicity.
Use: These lessons are provided free of charge, but are
not public domain. Each lesson represents an investment of time and
effort upon my part. All items are protected by the copyright laws of
the United States of America.
History: This project started in an effort to
provide new employees with worthwhile training, as corporate managers
are often reluctant to send people for organized training. Most people
are familiar with the excuse that if the company pays to train someone,
they would take the knowledge, and get a better job. This shifts the
burden of training new hires to co-workers, thus dropping productivity.
Either way, the company suffers.
As the person entrusted with many 'on the job' training efforts, it
occurred to me that rather than having to teach everyone from the
ground-up, there might be some good training material on the
Internet. I was disappointed to find that most of the hits the search
engines dumped were commercial in nature, so I decided to create these
documents. I hope you find them helpful.
Admittedly, you may find an advertisement associated with each page.
Such is the cost of providing meaningful, free, content on the Internet.
The 'one hundred series' creates a foundation by introducing the concepts, history, and vocabulary of the telecommunications industry.
Lesson 101: This lesson introduces the concepts of what data telecommunications is meant to accomplish. It covers the equipment that is being connected (mainframe, minicomputer, server, terminal) and the nature of the connections (master-slave, peer-to-peer, client-server).
Lesson 102: This lesson introduces the devices that connect computer equipment to communications lines. It covers the evolution of equipment (modem, CSU, DSU) and the terms used to refer to communications services and providers (leased-line, switched, teleco).
Lesson 103: This lesson discusses the interconnection of equipment common a mainframe based data networks. It covers the evolution and utilization of front-end processors and terminal controllers.
Lesson 104:
 Coming Soon!
This lesson discusses the interconnection of equipment common to LAN-WAN data networks. It covers local interconnect hardware (hubs, MAUs) and equipment for integrating and extending LANs (bridges, routers).
Lesson 105:
Coming Soon!
This lesson introduces the basics of a private voice network. It covers use of the PBX (stations, DNs, DID/non-DID), connection to the public network (COT, FX, Megacom), and the lines that network PBXs (trunks, OPX, tie).
The 'two hundred series' explores the technical aspects of particular systems.
Lesson 201: This lesson discusses the multi-point data line. It covers the portions of the public network (bridge, segment, drop) and problems that can crash the line (streamers, loopbacks).
Lesson 202:
Coming Soon!
This lesson covers the evolution of the multiplexer.
Follow these links to other telecom tutorials available on the web.
- Scan Technologies: Originally offered on US Datacomm's Homepage, these entertaining tutorials cover subjects such as ISDN, Frame Relay, ATM, and TCP/IP. I highly recommend these: they are the second best on the Web.
- South Hills Datacom: Dozens of well illustrated and to the point telecom lessons. Recommended reading includes Token Ring, Ethernet, ADSL Technology, and T1 Basics.
- CTC Communications: A bit drab for the net, this paper offers some insight into voice communications.
- PC Tune and Lube: For the someone serious about data-telecom, I recommend the Introduction to SNA tutorial.
