| Description | The cumulative Protection Switching Duration (PSD) time in
seconds. For a working channel, this is the cumulative number
of seconds that service was carried on the protection line.
For the protection line, this is the cumulative number of
seconds that the protection line has been used to carry any
working channel traffic. This information is only valid if
revertive switching is enabled. The value 0 will be returned
otherwise.
Discontinuities in the value of this counter can occur at
re-initialization of the management system, and at other
times as indicated by the value of
apsChanStatusDiscontinuityTime. For example, if the value
of an instance of apsChanStatusSwitchoverSeconds changes
from a non-zero value to zero due to revertive switching
being disabled, it is expected that the corresponding
value of apsChanStatusDiscontinuityTime will be updated
to reflect the time of the configuration change. |
