2.1.2 Ring Configuration

In the ONS 15200 ring configuration, wavelength channels exist between an ONS 15252 MCU and several ONS 15201 SCUs. A CLIP module installed in the ONS 15252 MCU exchanges data with an associated CLIP module installed in an ONS 15201 SCU.

You can install the ring configuration with or without fiber-optic protection. The ring configuration supports SONET or SDH ring protection and 1+1 APS client-layer protection.You can also arrange the ring configuration to use layer-3 load sharing. Figure 2-2illustrates the ring configuration with hubbed traffic.

Note The physical connection in Figure 2-2consists of two fiber-optic cables.
