4.15 Wireline Interface
The Consolette supports a balanced Wireline Interface on a dedicated RJ45 on its rear panel.
The Wireline supports:
• 2-wire or 4-wire operation
• 600-ohm loading or open bridge on both the receive and transmit paths
This interface can be used in conjunction with an E&M interface, Tone Remote Control, or ACIM
interface.
4.15.1 E&M with Wireline
E&M operation is provided by the Wireline Interface in conjunction with:
• Hardware PTT – an input to the rear panel DB25 that when asserted by an external
device causes the Consolette to transmit the audio that is currently on the wireline path.
• Chan_Act_Relay_Out – a rear panel DB25 output of a normally open onboard relay
which closes (and routes rear panel DB25 relay input Chan_Act_Relay_In) when the
Consolette is receiving qualified audio.
4.15.2 Tone Remote Control Operation
The Wireline Interface can be used in conjunction with a Tone Remote Control (TRC) Deskset or
Console. The Consolette supports the following remote control functionality via Tone Remote
