Table 15 - Interface Status During Various States
SIGNAL STATE STATUS
Control Channel:
Vol/Sq (J7-2) Data High Speed signaling is being routed to the HSD Detector.
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).
RPT Inhibit (1950 DIS) (J6-5) Low If a Voting system, this line is low during a Control Channel. The 1950
tone is present on the Line Output.
Rem PTT (J7-9) High No inbound calls from console or IMC.
Delay PTT (J6-1) Low Transmitting (HSD).
Rem PTT (J6-16) High 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) Analog If Voter or Simulcast, these lines contain modem communication between
the Voter and Main Site/Control Point GETCs, otherwise inactive.
Working Channel (Inactive):
Vol/Sq (J7-2) Data Not Listening for data.
RUS In (J7-14) 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).
RPT Inhibit (1950 DIS) (J6-5) Low If a Voting system, this line is low during a Control Channel. The 1950
tone is present on the Line Output.
Rem PTT (J7-9) High No inbound calls from console or IMC. Line not considered until channel is
assigned.
Delay PTT (J6-1) High Not Transmitting.
Rem PTT (J6-16) High No calls from the remote line allowed until channel is assigned.
DET DIS (J6-10) Low High speed data disabled, low speed data enabled.
MOD Out (J7-4) Data No High speed data is sent to the station on this line now.
CG HI (J7-4) Data No Low speed data until channel is assigned.
Phone lines (J6 6, 7, 8, & 9) Analog If Voter or Simulcast, these lines contain modem communication between
the Voter and Main Site/Control Point GETCs, otherwise inactive.
