Cisco ONS 15530 and Cisco ONS 15540 Collocated Topologies
The Cisco ONS 15530 can be combine with a Cisco ONS 15540 ESP or Cisco ONS 15540 ESPx system
in the same network node. 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 where aggregated services are
required.
Figure 6-53 shows a logical view of an hubbed ring topology consisting of collocated
Cisco ONS 15540 ESPx and Cisco ONS 15530 shelves as the hub node and Cisco ONS 15530 shelves
as the spoke nodes. This configuration can support transparent and aggregated services.
