SONET Topologies

This chapter explains how to set up the Cisco ONS 15327 in different SONET topologies, including:

•

Two-fiber bidirectional line switched rings (BLSRs) 

•

Unidirectional path switched rings (UPSRs)

•

Subtending rings 

•

Linear add/drop multiplexers (ADMs) 

•

Path-protected mesh networks (PPMNs) 

5.1  Before You Begin

To avoid errors during network configuration, Cisco recommends that you draw the complete ONS 
15327 SONET topology on paper (or electronically) before you begin the physical implementation. A 
sketch ensures that you have adequate slots, cards, and fibers to complete the topology.

Table 5-1

 shows the SONET rings that can be created on each ONS 15327 node.

5.2  Bidirectional Line Switched Rings

The ONS 15327 can support two concurrent BLSRs in one of the following configurations: 

•

Two, two-fiber BLSRs, or 

•

One two-fiber BLSR.

Each BLSR can have up to 32 ONS 15327s. Because the working and protect bandwidths must be equal, 
you can create only OC-12 or OC-48 BLSRs.
