This attribute displays whether an Idle failure condition has been
reported on the DS3 port. An Idle condition is reported when DS3
Idle defects have been observed and accumulated for a period of 2.5
seconds +/- 0.5 seconds. The DS3 Idle defect is the occurrence of a
valid DS3 frame with the information bits set to a 11001100..
sequence. If the DS3 Idle defects are intermittently occurring, the
DS3 Idle defect accumulator is decremented at a rate of 1/10 of the
incrementing rate (alarm integration ratio of 1/10), with all
measurements based on a 200 ms polling cycle.
The DS3 component goes into an operational state of disabled until
the Idle failure condition is cleared. The failure condition is cleared
when the DS3 idle pattern has not been detected for at least 10
seconds +/- 0.5 seconds.
The rxIdle attribute is always set to off when the component has
been locked and left offline.
The idle pattern indicates that the far-end is physically connected
but not put in service. For instance, DS3 idle is transmitted on the
outgoing line when the DS3 component is locked and not used for
operational testing.
