Table 10 - Interface Status During Various States
STATE
Data
High Speed signaling is being routed to the HSD Detector.
High
Receiver is unsquelched and watching carrier activity for the presence
(present = Low) of an interfering signal (without valid signaling).
Low
GETC is receiving HSD and mutes the receiver (no Receiver audio to the
transmitter).
Low
If a Voting system, this line is low during a Control Channel. The 1950 tone
is present on the Line Output.
High
No inbound calls from console or IMC.
Low
Transmitting (HSD).
High
No calls from the remote line allowed when Control Channel.
High
Transmitting high speed data, low speed data disabled.
Data
Control Channel Data to be transmitted is sent into the station on this line
now. (Simulcast Transmit Site.)
Data
No Low speed data during Control Channel signaling.
Analog
If Voter or Simulcast, these lines contain modem communication between the
Voter and Main Site/Control Point GETCs, otherwise inactive.
Data
Not Listening for data.
High
Watching carrier activity for the presence (present = Low) of an interfering
signal (without valid signaling).
Low
Receiver is muted (no Receiver audio to the transmitter).
Low
If a Voting system, this line is low during a Control Channel. The 1950 tone
is present on the Line Output.
High
No inbound calls from console or IMC. Line not considered until channel is
assigned.
High
Not Transmitting.
High
No calls from the remote line allowed until channel is assigned.
Low
High speed data disabled, low speed data enabled.
Data
No High speed data is sent to the station on this line now.
Data
No Low speed data until channel is assigned.
Analog
If Voter or Simulcast, these lines contain modem communication between the
Voter and Main Site/Control Point GETCs, otherwise inactive.
