A Network Configuration Requirements

This chapter introduces the network configuration requirements of the OptiX OSN 3500, including:

n  Network identity (ID) and internet protocol (IP) configuration requirements

n  Board configuration requirements

n  Equipment-level protection configuration requirements

n  Network-level protection configuration requirements

n  Orderwire & embedded control channel (ECC) configuration requirements

n  Clock configuration requirements

n  Auxiliary interface configuration requirements

A.1  Network ID and IP Configuration Requirements

1.  ID and IP

Each NE must have an independent ID, by which the ECC communication can be carried on between NEs. The ID of the OptiX OSN 3500 NE is set through the software.

Generally, only a gateway NE needs an IP address to communicate with NM.

In essence, ID and IP are independent from each other and they can be set separately. However, if you set the ID of the gateway NE first, the IP address of the gateway NE will vary with the ID for the lower 16 bits of default IP address of an NE is the ID of the NE. For example, if the ID is 1, the IP is 129.9.0.1 by default. If the IP address is set manually, the change of ID will not affect the IP address.

2.  Configuration Requirement

Table A-1 lists the configuration requirements of network ID and IP.

ID

In the network managed by an NM, the ID of NE is unique.

In a ring network, the ID of NE should increase one by one along the direction of the primary ring.

The ID of main subrack should be allocated prior to that of extended subrack.

In a complex network, the ID of station on ring should be allocated before that on chain. For example, if the ID of station on ring ranges from 1 to N, the ID of station on chain should be N+1, N+2¼.

When adding NE, the IDs of existing NEs remain unchanged and the IDs of new NEs increase along the primary ring on condition that it is unique.

IP

An IP address is necessary for gateway NE and is optional for non-gateway NE.

The default subnet: 129.9.0.0, subnet mask: 255.255.0.0.

The IP address of NE needs not to be set manually because it varies with ID.
