The configurations of services accessed by the ONUs remain the same after the Type B protection is
configured. That is, the service configurations are applied only to the working GPON port.

Configure the Type C single homing protection.
shows networking diagram for the Type C single homing protection. Configure
two 1:N optical splitters, one for connecting the working PON ports on the OLT and ONUs,
and one for connecting the protection PON ports on the OLT and ONUs. This protection
scheme protects both the backbone fibers and tributary fibers.
The configurations of services accessed by the ONUs remain the same after the Type C
single homing protection is configured. That is, the service configurations are applied only
to the working PON port on the OLT and working upstream PON ports on the ONUs.
