Unsigned32
When a primary channel is swapped with the spare channel, if the rollback
is configured, the primary channel is periodically measured for
signal quality in the background using the 9th receiver.
This object is the time between two consecutive signal quality measurements
of the primary channel.
This object applies to DRX and CMTS 2x8.
Units are in seconds.
