Proposed syllabus for online Telecommunications course.


This syllabus is posted to give prospective students an idea of what the course will be like.


Note:  minor changes will probably take place before the course begins on January 23.  The final, official, syllabus will be placed on the college’s Blackboard site and will not be changed once it is posted there.


Course description


ENT 283.  Telecommunications                        3 credits


Data communication systems, including LAN and WAN networks, modems and interfaces, and software protocols and standards.  Prerequisite:  Computer or electronics background.


Course outcomes


The following list of course outcomes is taken from the ENT 283 course master syllabus.  After successfully completing the course, you should be able to accomplish the following tasks:


1.         Calculate signal-to-noise ratio, channel capacity and system data “throughput” for a given system.

2.         Generate ASCII and EBCDIC bit codes for a given character (using tables).

3.         Configure an RS-232 interface (DCE-DTE) on paper including data, control-handshake lines, pin-outs” and wiring diagram.  Describe voltage levels for “mark,” “space,” and control signals.

4.         Differentiate among the RS-232, -449, -422, and -423 protocols used for serial interfaces.

5.         Describe the simplified operation of the public telephone network (protocols, signal levels, etc.) using standard telephone system terminology.

6.         Describe the different FDM and TDM multiplexing systems used in the public telephone system, including the channel capacities for the T-1, T-3 hierarchy.

7.         Describe the operation of a generic modem, including the differences between the various Bell modem types.

8.         Describe TDR operation.

9.         Generate the vertical and horizontal error detection parity bits for a short message.  Describe how CRC is used for error detection and correction.

9.         Describe BER measurement.

10.       Describe the basic operation of cellular telephone technology and its limitations.

11.       Describe the 7-layer OSI model, including hardware, protocols, and data representation used at each level.



Required materials


Textbook:  to be determined.  We are changing the text for this course.  As soon as the new text is determined, it will be posted.


A scientific calculator.  (A simple, non-programmable, non-graphing calculator should cost under $20.)



Each student will be graded on weekly web-based assignments.  Students should anticipate doing problems and one other assignment each week.  Depending upon the assignment, they may be sent to the course’s on-line discussion (“chat”) area, or emailed to the instructor. 


Problems from the text will be assigned weekly, and students will email their responses to the instructor by Sunday at midnight.  Answers will be posted each Monday.


To help students learn via an online “community,” there will be an assignment each week that will require posting and discussing items in the course discussion area.  For example, a typical assignment might involve determining the bandwidth of your personal Internet connection, and then comparing results.  We will also post short reviews of news items relating to the telecommunications industry.


One assignment will consist of a short paper on a telecommunications topic of the student’s choice, but approved by the instructor.




There will be two.  You will have to take them at the college’s testing center at the Largo campus.
