Configuring Timers

You can configure timers per ERPI to control the ERPI's switching and convergence parameters. The following
timers are available:
•
Wait to Restore (WTR) Timer – Defines a minimum time the system waits after signal failure is recovered
before reverting to idle state.
•
Guard Time – Prevents unnecessary state changes and loops.
•
Hold-Off Time – Determines the time period from failure detection to response.
To configure the ERPI timers:
1 Select Ethernet > Protocols > G.8032 > ERPI Attribute. The G.8032 ERPI Attribute page opens
2 Select the ERPI and click Edit. The ERPI Attribute – Edit page opens
3 In the ERPI WTR field, enter the Wait to Restore (WTR) timer (in minutes). The WTR timer is a minimum
time the system waits after signal failure is recovered before reverting to idle state.
4 In the ERPI Guard Time field, enter the ERPI guard time (in msec). You must enter a multiple of 10. The
guard time is the minimum time the system waits after recovery from a signal failure before accepting new
R-APS messages. The purpose of this timer is to prevent unnecessary state changes and loops.
5 In the ERPI Holdoff Time field, enter the ERPI hold-off time (in msec). You must enter a multiple of 100. The
hold-off time determines the time period from failure detection to response.
6 Click Apply, then Close.
