The ATM assembly telephone set is intended for using by those employed at installations or maintenance of telephone and ICT networks and repairs of telecommunication devices.
The set allows testing the telephone lines powered by 24V to 60V DC and loaded with 15 to 70mA DC.
The testing results are signalled by relevant lights of 3 LEDs on the telephone body.
The telephone casing is made of plastic with very high mechanical performance so the set is characterised by high resistance to mechanical exposures, impacts and falls. The telephone is fitted with 2 sets of connection cables: the flat cable ended with RJ11 micro-switch and the measuring cables ended with crocodile clips.
