Feedback 58-001 Telephony Training System

The Feedback range of Telecommunications training equipment has been designed to provide a modern, efficient approach to training the engineers and technicians working in this field.

    Features

  • Uses Discovery Software
  • Uses commercial telephony components
Description

Telephone and Interface Signalling, speech circuits and the immediate interface at the switching centre are examined. The use of a high quality, commercial telephone hybrid circuit in the subscribers line interface (SLIC) allows useful measurements to be made. TDM/PCM Principles Allows the study of the principles TDM/PCM. It is based on the use of standard telephony devices but also uses special circuits to demonstrate the effects of variable sampling rate, bit rate and filtering. PAM is used to demonstrate the concept of taking short samples to represent a continuous waveform. TDM is demonstrated by multi-channel PAM which demonstrates the principle of sharing a single physical link between different communication channels.
