Management Network Connectivity
This chapter provides an overview of ONS 15454 SDH data communications network (DCN)
connectivity. Cisco Optical Networking System (ONS) network communication is based on IP, including
communication between Cisco Transport Controller (CTC) computers and ONS 15454 SDH nodes and
communication among networked ONS 15454 SDH nodes. The chapter provides scenarios showing
Cisco ONS 15454 SDH nodes in common IP network configurations as well as information about
provisionable patchcords, the IP routing table, external firewalls, and open gateway network element
(GNE) networks.
Note This chapter does not provide a comprehensive explanation of IP networking concepts and procedures,
nor does it provide IP addressing examples to meet all networked scenarios. For ONS 15454 SDH
networking setup instructions, refer to the “Turn Up a Node” chapter of the Cisco ONS 15454 SDH
Procedure Guide.
Although ONS 15454 SDH DCN communication is based on IP, ONS 15454 SDH nodes can be
networked to equipment that is based on the Open System Interconnection (OSI) protocol suites. This
chapter describes the ONS 15454 SDH OSI implementation and provides scenarios that show how
ONS 15454 SDH can be networked within a mixed IP and OSI environment.
