Cisco ONS 15530 and Cisco ONS 15540 Mixed Topologies
The Cisco ONS 15530, Cisco ONS 15540 ESP, and Cisco ONS 15540 ESPx systems can be used in the
same network topology. The most common application is using a Cisco ONS 15540 ESP or
Cisco ONS 15540 ESPx as the hub node in a hubbed ring topology.
Figure 6-52 shows a logical view of an hubbed ring topology consisting of a Cisco ONS 15540 ESP as
the hub node and Cisco ONS 15530 shelves as the spoke nodes. The configuration supports transparent
services.
