Installation
This means that an ordinary two-wire system telephone can be connected to the onboard PABX unit/PSTN socket -
and the call can then be initiated from this telephone, e.g. from the captain's cabin or the cargo control room. The built-
in SMPS of 10-32 V DC generates the necessary current to support the PSTN telephone of the system.
