1. A system receiving a downstream optical signal at a transceiver unit coupled to an intercom system, the system comprising:

  • a receiver at a transceiver unit that receives a downstream optical signal and converts the downstream optical signal into an electrical communication signal;

    a first circuit in the transceiver unit that determines whether the transceiver unit couples the electrical communication signal to a two wire intercom circuit or a four wire intercom circuit;

    a second circuit in the transceiver unit that determines whether the transceiver unit couples the electrical communication signal to a four wire intercom station circuit or a four wire intercom matrix circuit in the case that the first circuit determines the electrical communication signal is coupled to a four wire intercom circuit based on a switch position of a switch of the transceiver unit; and

    an output port on the transceiver unit that outputs either a two wire intercom signal or a four wire intercom signal to an external communication device based on the first circuit determination.
