2.2 Network Protection

Release 1.1 provides the Forward Defect Indication (FDI) switch (fdi_switch), which can be enabled or disabled. When fdi_switch is enabled, the FDI alarm causes the traffic to switch paths. A CLIP receives the FDI alarm if and only if its companion CLIP loses its client-side input signal. The severity of the FDI alarm is minor.
