GTC Count is the number of GTC message transmissions by the transmitting transceiver through a single GTC
transmission.
GTC (Go to Channel) refers to a message sent through the voice channel for the transmitting transceiver to
guide the receiving transceiver to the data channel.
The transmitting transceiver will migrate to the data channel after transmitting the GTC if the Status, Short
Message is configured. When the receiving transceiver receives the GTC, it automatically migrates to the data
channel and stands by to receive the data.
-
The receiving transceiver waits to receive the Status, Short Message after the receiving transceiver migrates
to the data channel. The transceiver restores the voice channel if the transceiver does not receive the
acknowledgment within the time configured for Maximum ACK Wait Time.
The transmitting transceiver sends the Status, Short Message and waits to receive the acknowledgment after
the transmitting transceiver migrates to the data channel. The transceiver restores the voice channel if the
transceiver does not receive the acknowledgment within the time configured for Maximum ACK Wait Time.

■ Basic model
If the transceiver does not receive the acknowledgment after the transceiver sends data and the time configured
for Maximum ACK Wait Time elapses, the transceiver resends data. Number of Retries is the number of times
for the transceiver to resend data. A smaller number can be configured if there is good communicating
conditions, and a larger number can be configured if there are inferior communicating conditions.

'■ Standard model
■ Basic model
The transceiver confirms that the traffic channel is available before sending data and then starts sending data
when the channel is available. Transmit Busy Wait Time is the duration to wait for the traffic channel to become
available.
A transmission is canceled when the channel is busy and the Transmit Busy Wait Time elapses.

'■ Standard model
■ Basic model
Maximum ACK Wait Time is the length of time that the transceiver stands by to receive the acknowledgment
after the transceiver sends data.
If the transceiver does not receive the acknowledgment within the time configured for Maximum ACK Wait Time,
the transceiver resends data.
-
In FleetSync, It is also used for the standby time interval in the data channel upon moving to the data channel
using GTC.
In FleetSync, The receiving transceiver stands by to receive the next data for the time configured for
Maximum ACK Wait Time after receiving the previous data.
