Abstract:
A telecommunications apparatus, adaptable to be coupled to a telecommunication signal processing apparatus, for establishing bi-directional communication between at least one incoming line and at least one station line, comprising:an input port adapted to be directly coupled to a first one of the at least one incoming line so as to receive a communication signal being transmitted thereon, the communication signal having an AC component and a DC component; a switching apparatus, coupled to the input port and being adapted to establish bi-directional communication between the first incoming line and any of the at least one station line in response to a control signal provided by the processing apparatus; and a coupling device which is adaptable to substantially isolate the switching apparatus from at least the AC component of the communication signal when the processing apparatus is receiving the AC component, and which is adaptable to input the AC component into the switching apparatus so as to enable the switching apparatus to establish said bi-directional communication while substantially isolating the processing apparatus from the AC component and enabling the processing apparatus to receive and monitor the DC component.
