Description
Disabled

The RDL-3000 is configured with a single fixed frequency.
If the wireless link is lost, the RDL-3000 continuously
monitors the RF channel for an opportunity to re-establish
the link.
Enabled
Disabled
Auto scan is enabled and the RDL-3000 is configured with
one or more discrete channels or frequency ranges.
If the wireless link is lost, the RDL-3000 continues to monitor
the RF channel for an opportunity to re-establish a link with
the same sector controller ('stickiness'). If the wireless link is
not restored within the period specified by the Stickiness
Timer (e.g., 300 seconds), the RDL-3000 starts a new
frequency scan.

Threshold is minimum UBR for uplink and downlink
If the wireless link is lost, the RDL-3000 continues to monitor
the RF channel for an opportunity to re-establish a link with
the same sector controller ('stickiness'). If the wireless link is
not restored within the period specified by the Stickiness
Timer (e.g., 300 seconds), the RDL-3000 starts a new
frequency scan.
If the link is active, but the uplink or downlink UBR level
drops below the minimum UBR threshold for an period
exceeding the Threshold Timer value, the RDL-3000 drops
the wireless link and starts a new frequency scan.
