APS Modes
What happens after traffic has switched to the protection channel depends on the APS
configuration. There are three modes:
• Non-Revertive mode prevents traffic from automatically switching back to the working
channel when it becomes operational. In this mode, traffic remains on the protection
channel until it is manually switched back to the working channel or the card is reset. This
is the default mode.
• Non-Revertive Auto-Switch mode automatically switches traffic back to the working
channel if the protection channel fails and the working channel failure is cleared.
• Revertive mode automatically switches traffic back to the working channel when the
working channel failure has been cleared for a user-specified amount of time, from 5 to 12
minutes.
APS Commands
Manual commands provide further control over APS operation. Some commands temporarily
disable automatic switching. These commands must be manually cleared to return to normal
APS operation.
•
Lockout Protection disables automatic switching.
•
Force to Protection forces traffic to the protection channel and disables automatic switching.
•
Force to Working forces traffic to the working channel and disables automatic switching.
•
To Working if Ready forces traffic to the working channel, if there are no conditions (such as
a working channel failure) that prevent the switch. This command does not disable
automatic switching.
