OptiX RTN 380 AX PLA Configuration

Hello friend！

Two RTN 380A/380AXs can be cascaded to form a PLA group.

The master and slave NEs in a PLA group must be specified and use a service port for PLA signal cascading. For an RTN 380A/380AX, the GE optical port, GE electrical port, and COMBO port can be used to cascade PLA signals.

Based on service access modes, three PLA system configuration modes are available:

Service access through a single NE

Only the master NE is used for service access. This configuration mode provides protection for microwave links but not for equipment.

Figure 1 Example of service access through a single NE

Service access through an E-LAG

Figure 2 Example of service access through an E-LAG

• Both the master and slave NEs are used for service access. Inter-NE E-LAG is configured. This configuration mode provides protection for microwave links, equipment, and access links.

• This configuration mode requires the service source (an IDU or user equipment) to provide two access ports and support static LAG. The LAG of the service source and the E-LAG on the RTN 380A/380AXs can cooperate to implement protection switching for both equipment and access links.

Service access through an optical splitter

• Both the Ethernet optical ports on the master and slave NEs are used for service access. This configuration mode provides protection for microwave links, equipment, and access links. In normal cases, the service optical port of the slave RTN 380A/380AX does not transmit optical signals. If the master RTN 380A/380AX fails, the service optical port of the slave RTN 380A/380AX is activated for service access.

• LAG is not required in this configuration mode.

When physical link aggregation (PLA) is required to improve Ethernet service bandwidth or reliability on microwave links, you need to create a PLA group.
