SIGNAL SUBCOURSE 334
TELEPHONE CIRCUIT CONDITIONING
INTRODUCTION
To effectively condition telephone circuits, you need to know the
characteristics of communications systems as well as the characteristics of
the communications circuits over which these signals will pass.
You will
need to know the characteristics of the various pieces of equipment which
make up the circuits and the type and operation of test equipment used in
circuit conditioning.
This subcourse is designed to build on the skills and knowledge you
already possess so that you will be able to perform as a circuit
conditioner, should the need arise.
STUDENT ACTIONS
Specific objectives for each lesson are listed at the beginning of each
lesson. The following is a brief summary of these objectives:
1. To enable you to use the formulas necessary in the calculation of
certain impairments.
2. To enable you to determine the effects of and the corrective actions
taken to reduce the effects of amplitude vs frequency distortion and
envelope delay distortion.
3. To enable you to identify technical parameter codes and to use the
proper test description numbers for each parameter code.
4. This subcourse is comprised of three lessons and an examination. A set
of lesson objectives for each lesson is contained within the individual
lesson module. The lessons are as follows:
