2.1.6 Full-Mesh Configuration
In the ONS 15200 full-mesh configuration, all ONS 15252 MCUs communicate with each other.
A single Network Control Board (NCB) module located in one of the ONS 15252 MCUs manages the
full-mesh configuration. The NCB modules in the other ONS 15252 MCUs are not used; an NCB front
cover replaces them.
In the full-mesh configuration, you can configure SONET or SDH ADM ring protection on the client
side of the units. Layer-3 load sharing is supported. To implement client-layer 1+1 APS protection, you
must replace each of the units with a pair of units transmitting in opposite directions of the ring.
Figure 2-6 illustrates the ONS 15200 full-mesh configuration.
Note The physical connection in Figure 2-6 consists of two fiber-optic cables.
