Service Planning

The service planning information contains the information about all the parameters required for configuring the NE data.

• There are more than 40 sets of optical transmission equipment and more than 40 sets of radio transmission equipment on the network. Therefore, divide the ECC network into two DCN subnets according to the types of equipment.
• Select the central node NE101 of the optical transmission service and the central node NE202 of the radio transmission service as gateway NEs.
• The NMS and NE101 are located at the same place and NE202 is located at another place. Therefore, you need to construct the external DCN between the NMS and NE202 through a router or protocol converter.

• Allocate IDs and IP addresses for all the NEs based on the network conditions.

• Plan the extended ECC.

  • There is no DCC between NE203 and NE204 or between NE203 and NE205. Therefore, you need to use network cables to connect the Ethernet network management ports and the NE cascading ports to extend the ECC. The extended ECC function works in the automatic mode.
    NOTE:

    If FE/GE services are configured between NE203, NE204, and NE205, communication between the three NEs can also be implemented based on the inband DCN. To prevent interchange between different protocols, the inband DCN uses the HWECC protocol.
  • As NE101 and NE202 function as gateway NEs, you need to disable the extended ECC function on these NEs.

• Divide the ECC network.

  • Shut down the DCC channels of the east and west ports on NE201 so that the DCC between two DCN subnets is disconnected.
  • Set pass-through of the D1 to D3 bytes on NE201. In this manner, the ECC route protection function is not affected.
