41.2 Downlink Port Protection Switching
The downlink port protection switching feature creates a working path (active port) and backup
path (backup port) for downlink traffic.
Put downlink PON (GPON) ports into active and backup pairs. Normally, the downlink traffic uses
the working path (traffic is sent out the active port). When the active port is down, the OLT sends
out packets using the backup path (traffic is sent out the backup port).
