The FE-FRCDWKSWBK-SPAN condition is not used in this platform in this release. It is reserved for
development.

2.6.65 FE-FRCDWKSWPR-RING

The Far End Ring Working Facility Forced to Switch to Protection condition occurs when a far-end node
ring is forced from working to protect using the FORCE RING command. This condition is only visible
on the network view Conditions tab.
The prefix FE means the main alarm is occurring at the far-end node and not at the node reporting the
FE-FRCDWKSWPR-RING condition. Troubleshoot the FE condition by troubleshooting the main alarm
at its source. The secondary alarms or conditions clear when the primary alarm clears.
