GPON Redundancy
The V8102 provides up to 36 GPON OLT ports, and supports the redundancy of OLT port
for the stable network service. Through this function, the system can group the specific
GPON ports in order to make a standby OLT port operate instead of a working one when
this does not operate normally. This redundancy prevents the service from halting, and
guarantees reliability of communication service.

Redundancy Type B with SIU_GPON16
The redundancy type B allows GPON redundancy by either port or card basis. Therefore,
it can be configured between port #A and port #B within the same line card or different
line card, or between slot 1 and 2 within the same chassis.
The following table shows OLT redundancy components.
Item
Description
Master OLT
Primary port in redundancy group. DB of this port is to be synchronized with
Slave OLT.
Slave OLT
Secondary (= redundant) port in redundancy group. It copies DB from Master
OLT and its own DB is initialized.
Working OLT
Active port in service in redundancy group.
Standby OLT
Standby port in redundancy group.
Tab. 12.1
OLT Redundancy Components
You can configure the OLT port redundancy by grouping two OLT ports and specifying
each one to Master and Slave. Master OLT is the primary port which plays the role of cri-
terion for DB synchronization and the configuration commands. Slave OLT is the addi-
tional port for port redundancy, whose DB is initialized and synchronized with the Master
OLT's when it is configured as a redundancy group's entry.
Basically, Master OLT operates as Working OLT. If the Working OLT fails or does not re-
ceive a signal for a certain reason, a switchover to Standby OLT occurs to keep the ser-
vice on.

Redundancy Group
OLT redundancy is configured based on a group ID. To configure the OLT redundancy
group, use the following command.
