SETEL D
The selective party line telephone set SETEL-D, with integrated decoder, is used in classical party line networks and as a service telephone in SDH/PDH communication networks.
The SETEL-D is compatible with the SETEL and existing ABB party line telephone systems. SETEL-D combines the functions of a 4-wire telephone set and a DTMF decoder. When used together with the 4-way bridging amplifier (J3KA), a complete party line telephone system can be built.
