Product Configurations

This chapter describes common Cisco ONS 15200 network confi gura tio ns. A ll mo dules men tio ned i n

this chapter are described in more detail in Chapter5 , “Module Descriptions.”

2.1 ONS 15200 Network Configurations

The ONS 15200 operates in several network configuration arrangem ents. All ONS 15200 configurations

consist of one or more ONS 15252 Multichannel Units (MCU) or ONS 15201 Single-Channel Units

(SCUs). The following information describes some standard ONS 15200 network configura tions,

including:

•The “Bus Configuration” section on page 2-1

•The “Ring Configuration” section on page 2-2

•The “Dual-Home Configuration” section on page 2-3

•The “Multichannel Point-to-Point Configuration” section on page2-3

•The “Ring Configuration with Hubbed and Meshed Traffic” section on page2-4

•The “Full-Mesh Configuration” section on page2-5

2.1.1 Bus Configuration

In an ONS 15200 system bus configuration, wavelength channels link an ONS 15252 MCU to ONS

15201 SCUs. Use this configuration only in networks where optical-layer fiber protec tion is

unnecessary. It is possible to configure the bus configuration for layer-3 load-sharing protection or cl ient

layer 1+1 APS, but the two data traffic flows would need to share the same optical fiber path, and

therefore protection would be incomplete.

In the bus configuration, the Client Layer Interface Port (CLIP) modules located in the ONS 15252 MCU

and in each ONS 15201 SCU exchange data. Figure 2-1 illustrates the ONS 15200 system bus

configuration.

Note The physical connection in Figure 2-1 consists of two fiber-optic cables.
