Understanding Automatic Telephone Exchange/Epabx System

Understanding Automatic Telephone Exchange / EPABX System is an ideal training platform to learn the operation of Automatic Telephone Exchange/ EPABX. It is demonstrator cum training system specifically designed for the comprehensive practical study on Automatic Telephone Exchange / EPABX System for the beginners with a basic knowledge of the various electronic building blocks and fundamentals of communication system. This didactic product develops the sense of investigation within the student and familiarizes him with repair techniques/design techniques. One of the main features of this training system is fault simulation to educate on actual fault finding, by simulating faults on this platform. The complete block diagram of EPABX System is printed on the mimic. Finally this equipment allows us to do experiments and to observe waveforms/signals/voltages of different sections, which are guided thoroughly by theory and product tutorials to gain in-depth knowledge of the system.

FEATURES:-

• Study of switching phenomena
