Management Network Connectivity
This chapter provides an overview of Cisco ONS 15310-MA 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 15310-MA SDH nodes,
and communication among networked ONS 15310-MA SDH nodes. The chapter provides scenarios
showing ONS 15310-MA 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.
Although ONS 15310-MA SDH DCN communication is based on IP, ONS 15310-MA SDH nodes can
be networked to equipment that is based on the Open System Interconnection (OSI) protocol suites. This
chapter describes the OSI implementation and provides scenarios that show how the ONS 15310-MA
SDH can be networked within a mixed IP and OSI environment.

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 networking setup
instructions, refer to the “Turn Up a Node” chapter of the Cisco ONS 15310-MA SDH Procedure Guide.
Note To connect ONS 15310-MA SDH nodes to an IP network, you must work with a LAN administrator or
other individual at your site who has IP networking training and experience.
