John Wiley & Sons, Publisher. 2) Telecommunications by Warren Hioki, Fourth Edition (2000). Prentice Hall, Publishers. 3) Laptop Computer with Microsoft Office, Lotus Notes, and Electronic Workbench. 4) Sharp EL-546L Calculator. Course An introduction to the techniques, principles, and terminology of Description: Data Communications will be presented. Public and private networks will be examined. Data communication equipment, multiplexing, and interactive learning, demonstrations will be employed. Laboratory exercises are required. (3 hours lecture, 2 hours laboratory per week, 4 credits) Prerequisite: Telecommunications I, Digital Electronics for Telecommunications
Course Upon completion of this course students shall demonstrate the Objectives: following competencies. 1) Understand basic data communication techniques and principles. 2) Explain the use and application of various transmission media. 3) Describe current data communication services and their applications. 4) Define modulation techniques, coding schemes, and error correction. 5) Identify sources of information and reference material for current and emerging technologies. Instructional Each class will start with a review of the previous section s Procedures: concepts and problems. This is an excellent time for students to ask any questions they may have concerning the material. New topics will be presented in a lecture format with many opportunities for class discussion and questions. Students may be asked to solve inclass problems and laboratory assignments independently or ingroups. The class will end with a summary of the day s concepts and a homework problem set which will be due at the next meeting. Blackboard will be integrated into the course as an integral part of course delivery and Next Step community development. Please check your account frequently at NSPinfo.com. Attendance It is expected that students be thoroughly prepared for class and Policy: participate in all class sessions. Attendance during Exams and Laboratory is required. Any student who will be absent from class must notify George Walsh at (978) 762-4000 x2150 or x6606 before the absence. Poor attendance or tardiness could negatively affect your grade.

Accommodation If you feel that due to a disability you have the need for special Statement: assistance and/or adaptations to accomplish the goals of this course, please see the instructor within the first week of class. Homework: Will be returned to the instructor at the class meeting following assignment unless instructed otherwise. Laboratory: Students are required to perform, and carefully report in an approved format, all laboratory experiments. Student s laboratory grade will
be based on laboratory preparation, performance, and formal reports. Exams: Grading Policy: There will be three exams during the semester. No make up exams will be given without prior approval of the instructor. Grades will be determined as follows: 75% Exams 10% Laboratory Work 10% Project and Technical Presentation 5% Homework and Class Participation This schedule and course content is tentative and subject to change.
