Product Configurations

This chapter describes common Cisco ONS 15200 network configurations. All modules mentioned in this chapter are described in more detail in Chapter 5, “Module Descriptions.”

2.1 ONS 15200 Network Configurations

The ONS 15200 operates in several network configuration arrangements. 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 configurations, 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 page 2-3

•The “Ring Configuration with Hubbed and Meshed Traffic” section on page 2-4

•The “Full-Mesh Configuration” section on page 2-5

2.1.1Bus 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 protection is unnecessary. It is possible to configure the bus configuration for layer-3 load-sharing protection or client 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 2-1illustrates the ONS 15200 system bus configuration.

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