SIGNALING EVENT DESCRIPTION
F Control Channel Idle
The trunking analyzer outputs a background pattern on the control channel to
lock the radio.
J
ISW Received
The radio sent an Inbound Signaling Word (ISW) on the control channel to
indicate the radio has been keyed.
Q

speed data on the voice channel.
S
HS ACK Received on VC
The radio sends high-speed acknowledge tone on the voice channel indicating
it received the high-speed data from the trunking analyzer.
U

W
Disconnect Tone Received on
VC
The radio sent a disconnect tone indicating it has de-keyed. Disconnect Tone
Received on VC verifies the receipt of proper disconnect signaling.
X
