Busy/Idle (FOCC)
This field selects the busy/idle status information to be included in the signaling
sequence.
• Idle sets the busy/idle bits of the forward control channel information to indicate an
idle state.
• Busy sets the busy/idle bits of the forward control channel information to indicate a
busy state.
• WS Delay, word sync delay, prevents a busy/idle change until the word sync
information has been received and a defined number of delay bits has been counted.
The delay bit value is set in the B/I Delay field.
• 1stBitDly, first bit delay causes the busy/idle bit to be set after a bit has been
received and a defined number of delay bits has been counted. The delay bit value is set
in the B/I Delay field.
B/I Delay (FOCC)
Busy/idle delay determines the number of bits that are counted before a busy/idle
bit changes from the Idle state to the busy state. This function is used with the WS
Delay
and 1stBitDly settings in the Busy/Idle field.
Bursts
This field defines the number of times the message data is output when Send is
selected. This function only works when the Send Mode field is set to Burst.
Channel
This field selects the forward control channel (FOCC) or forward voice control
(FVC) menus.
Data Level
This setting determines the signal level change that occurs when a logical high (1)
or low (0) is output. The unit-of-measure used depends on the AFGen2 To setting.
The direction of the output level change depends on the Polarity setting.
