ROI-S05749 SYSTEM SETUP
3-21
• APS Maintenance Mode
This is a setup to give priority to manual control operation in
maintenance.
Manual: Give priority to alarm events in maintenance
operation. In this mode, manual control disables the
operation under alarm condition.
Forced: Give priority to forced control in maintenance
operation. In this mode, manual control enables the
operation under alarm condition and the alarmed side
can be selected.
Caution: When the APS Maintenance Mode is set to
“Forced” in provisioning, APS manual control can
select either Working or Protection line though one
is alarmed. Then, take care switching to avoid traffic
interruption.
• APS Condition-SF(PROT):
This is a setup to give higher priority to switchover by SF in
Protection side.
Priority High: This setup gives highly priority to SF of Protection
side (installed in INTFC Slot2) for switchover
control condition. Since the setup gives priority
higher than the Forced Control, the ONLINE is
maintained in Main side (installed in INTFC Slot1)
under occurrence of SF condition of Protection side.
