EPABX Trainer.
Telephone exchange an electronic boon to the
mankind serving from decades for communication. Its one of the best
combination of Analog, Digital & Mechanical circuits. The exchange
technology has undergone many phase of changes ever since its existence.
Automatic Telephone Exchange Training / EPABX System forms the basic of
telephone exchanges, EPABX technology study.Both manual and automatic
switching can be performed. The functional blocks provides easy
understanding of the working of the system. Visualizations of the
switching and detections makes it unique. A DTMF Telephone Trainer is
supplied for better understanding of Telephony.
