Random Access Contention When a channel or all the repeater channels for Trunking mode is busy radio unit will not transmit depending on its Busy Channel Lockout setting in conventional mode As Soon as a channel is cleared some transmissions may crash Random access is used to avoid this by employing a random transmission sequence Number of Retries Number of Retries is the maximum number of retry transmission when no acknowledgement is received in the Maximum ACK Wait Time Increase this item to improve data communication reliability TX Busy Wait Time TX Busy Wait Time is the maximum amount of time be fore giving up the data transmission when the channel or all the repeater channels for Trunking mode is busy Also this timer affects if it expires during Random Access period Maximum Wait Time Maximum ACK Wait Time is the maximum amount of time to wait for an acknowledgement from the called radio unit It is used as an interval time of retries It must be set greater than the ACK Delay Time of the called radio unit 11 980 981 12 OPERATING FEATURES ACK Delay Time ACK Delay Time is the amount of time from the end of receiving a data to the beginning of sending an acknowledgement It should be adjusted as the repeater s hang up delay time Also it must be set less than the Maxi mum ACK Wait Time of the calling radio unit TX Delay Time RX Capture TX Delay Time is the a
