Description: The Analyst’s perspective of services, equipment and methods used in the telecommunications
Topic include forecasting , methods of evaluation of equipment, selection methods, RFPs. This class includes operating
policies, implementation issues, traffic analysis, trunking and routing. Four quantitative methods are used in four projects.
These project include: Evaluation matrix, Budgeting (operation budget and capital budget), Traffic engineering (SMDR
analysis and Erlang B and C tables) and project management (Gantt, CPM, PERT and PERT/COST). Topics are covered in
the book and on the WEB. Four proctored examinations are given by the external studies office. Contact them for an
appointment. With External Studies it is the student’s responsibility to read and study on your own. If you have questions
then ask your instructor. This is a big responsibility. Some general knowledge about the phone system is helpful as is
some knowledge of system analysis and design, but students without this can overcome these deficiencies by some extra
effort. Students must have access to the internet for email to the instructor and for downloading materials from the
net. Quantitative methods of analysis emphasized. Prerequisites CST-270 and CST-290 or consent. Computer
experience with spreadsheet is helpful.

Objectives: Upon completion of this course the student will:
        Use Quantitative methods to solve problems: Evaluation Matrix, Spreadsheet, CPM/PERT
        Develop an operations budget and capital budget
        Know and use forecasting methods
        Know the main features available on PBXs.
        Know the difference between requirements and specifications.
        Know the LEC and IXC services that are available.
        Know the important factors in evaluating contractors/consultants.
        Know the steps in developing an operations plan.
        Be aware of the problems in telecommunications security.
        Be able to evaluated capital expenditures using payback, NPV and IRR.
        Be able to develop and use CPM/PERT including probabilities of completion on time using standard deviation and
the Z table.
        Understand and use voice traffic engineering concepts: Busy hour, Blockage, Grade of Service
        Be able to select and use traffic engineering tables, Erlang B, Erlang C, and Poisson.
        Be able to understand, evaluate and use SMDR data.

Requirements: Buy a textbook: Irwin Handbook of Telecommunications Management 3rd ed, by Harry Green.
The work that you turn in is to be your own best effort. Work that is copied or done by someone else will receive a zero.
This applies to the copier and copyee.

Grades: Grades are based on total accumulated points. Accumulating 92% or more of the total points would equal an
“A”. 85%=B, 70%=C 60%=D.
Project Assignments are due before you take exams. The first project which is due as soon as possible; you don’t even
need the book. There will be 4 examinations @ 50 points each. You will be given specific question that you should be able
to answer. First project at 20 points, then 3 projects @ 40 points each.
