Alcatel-Lucent 7750 Configuration Manual page 373

When is port configured as a protection circuit of an APS group, the configurations described above and all
service configurations related to APS port are operationally inherited by the protect circuit. If the protect cir-
cuit cannot inherit the configurations (due to resource limitations), the configuration attempt fails and an
error is returned to the user.
The protect circuit must be shutdown before it can be removed from the APS group port. The inherited con-
figuration for the circuit and APS operational commands for that circuit are not preserved when the circuit is
removed from the APS group.
The no form of this command removes the protect-circuit.
Default
none
Parameters port-id — Specify the physical port that will act as the protection circuit for this APS group in the slot/mda/
port format.

defaults in the event of communication delays between the APS controllers.
rdi-alarms
Syntax rdi-alarms [suppress | circuit]
Context config>port>aps
Description This command configures how RDI alarms (line, path, section) are generated on physical circuits of an APS
ports. The command configuration changes are supported only for switching-mode set to uni_1plus1. The
configuration can be changed only when no working and protecting circuit has been added. Options:
•
•
Default rdi-alarms circuit
revert-time
Syntax revert-time minutes
no revert-time
Context config>port>aps
Description This command configures the revert-time timer to determine how long to wait before switching back to the
working circuit after that circuit has been restored into service.
A change in the minutes value takes effect upon the next initiation of the wait to restore (WTR) timer. It does
not modify the length of a WTR timer that has already been started. The WTR timer of a non-revertive
switch can be assumed to be infinite.

Modifying Hold-Down Timer Values on page 375
circuit–RDI alarms are H/W-generated independently on each working and protect circuit based on
RX failure of that circuit regardless of APS line status.
suppress–RDI H/W generation on working and protect circuits is suppressed. No alarms are
generated on RX failure of that circuit.
