RUS In (J7-14)
High
Receiver is unsquelched and watching carrier activity for the presence
(present = Low) of an interfering signal (without valid signaling).
Rus Out (J7-15)
Low
GETC is receiving HSD and mutes the receiver (no Receiver audio to the
transmitter).

No calls from the remote line allowed when Control Channel.
DET DIS (J6-10)
High
Transmitting high speed data, low speed data disabled.
MOD Out (J7-4)
Data
Control Channel Data to be transmitted is sent into the station on this line
now. (Simulcast Transmit Site.)
CG HI (J7-4)
Data
No Low speed data during Control Channel signaling.
Phone lines (J6 6, 7, 8, & 9)

High
Watching carrier activity for the presence (present = Low) of an interfering
signal (without valid signaling).
Rus Out (J7-15)
Low
Receiver is muted (no Receiver audio to the transmitter).
