The ET-836 is intended for the learning of the theory and practising of the central commutation and interior telephony networks. It incorporates a PABX exchange, internal telephone lines (analogue and RDSI), an external line simulator, tariff generator modules, channel simulator, fault simulator and connection points for analogue and digital (ISDN) terminals. It can be connected via modem and directly to a PC.

Last generation of telephone station ISDN / analogue
2 internal analogue lines
4 external analogue lines
4 external basic access So (B+B+D) (it allows the connexion un to 8 independent ISDN extensions)
Programming and configuration of the telephone station through PC
Simulation of an urban analogue station and the circuits of tarification
