Digital Talkset
When the Display Handset and Remote handset establish communication and are
connected by at least one correctly mapped wire pair, the units will support
simultaneous two-way audio communication through an external attached
microphone/headset. The actual communication from one handset to the other is
via a digital data stream and is compatible with fiber optics (via the fiber optic
adapter module).
Audio communication is initiated by assuring that the Talksets are properly
connected and momentarily depressing the Talk button on either the DH or the
RH.
If the wire map supports this, audio communications will be activated. Both the
RH and DH provide visual indication when the Talkset is active. The Talkset will
not function during any type of cable test operation.
