2.1.5 Ring Configuration with Hubbed and Meshed Traffic

In the ONS 15200 ring configuration with hubbed and meshed traffic, two ONS 15201 SCUs communicate with each other. You can use either unit in a direct point-to-point configuration through a control area network (CAN) bus connection as shown in Figure 2-5, or with a noninterfering ONS 15252 MCU. If you use an ONS 15252 MCU, the MCU must have an installed Bridge module (BM).

To manage a mesh configuration, use the Maintenance Manager (MM) software and associated hardware or use a CAN bus extension cable to connect one of the ONS 15201 SCUs using the meshed channel to the ONS 15252 MCU. An ONS 15201 SCU connected in this way will be on the same logical CAN bus as the ONS 15252 MCU.

In the mesh configuration, you can configure SONET or SDH ADM ring protection on the client side of the meshed channel. If you use client-layer 1+1 APS protection, you must replace each of the

ONS 15201 SCUs with a pair of ONS 15201 SCUs transmitting in opposite directions. Figure 2-5illustrates the ONS 15200 ring configuration with hubbed and meshed traffic.
