Interface Configuration
7750 SR OS Interface Configuration Guide Page 501
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 pro-
tection 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 cir-
cuit 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 chan-
nel 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.
