Switching-arch
The architecture of the APS group.
Revertive-mode
Displays the revertive mode of the APS group.
nonrevertive — Traffic remains on the protection line until another
switch request is received.
revertive — When the condition that caused a switch to the
protection line has been cleared the signal is switched back to the working
line.
Revert-time
Displays the configured time, in minutes, to wait after the working circuit
has become functional again, before making the working circuit active
again. If the revertive mode is non-revertive, then this field will be empty.
Rx K1/K2 byte
Displays the value of the SONET/SDH K1/K2 byte received on the
interface.
Tx K1/K2 byte
Displays the value of the SONET/SDH K1/K2 byte transmitted on the
interface.
Current APS Sta-
tus
Displays the current APS status.
Mode Mismatch
Cnt
Indicates the number of times a conflict occurs between the current local
mode and the received K2 mode information.
Channel mismatch
Cnt
Indicates the number of mismatches between the transmitted K1 channel
and the received K2 channel has been detected.
PSB failure Cnt
Displays a count of Protection Switch Byte (PSB) failure conditions. This
condition occurs when either an inconsistent APS byte or an invalid code is
detected.
FEPL failure Cnt
Displays a count of far-end protection-line (FEPL) failure conditions. This
condition is declared based on receiving SF on the protection line in the K1
byte.
No. of Switcho-
vers
Displays the number of times a switchover has occurred.
Last Switchover
Displays the time stamp of the last switchover.
Switchover sec-
onds
Displays 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.
Signal Degrade
Cnt
Displays the number of times the signal was degraded.
