The Telephony Trainer ET-836 is an educational integral system destined to the learning of the theory and the practise of PABX stations, the indoor telephony networks and the telephony systems, as well as to the development of the skills of installation and assembly.
Each one of the ET-836 modules has an active block diagram, with telephone connectors and points of test, that allow the connexion of telephone lines and the terminals. In the test points the telephone signals can be observed, to analyse their different states and to measure their parameters. Also they allow the study of the typical errors of wiring.
