Basic DCN principles
...................................................................................................................................................................................................................................
Purpose
This subsection serves as an entry point, it describes the basic DCN principles. The
following subsection describes common DCN configurations. DCN configuration
guidelines for 1643 AM products, NSAP address formats, and other related information
are provided thereafter.
A Data Communication Network (DCN) is used for the exchange of management data.
This section provides an overview of the Data Communication Network and describes
the type of communication between the nodes in the network and the used protocols.
SDH management network
The SDH management network is an overlay of the transmission network. The Element
Management System (EMS) and the Network Elements (NEs) together are the nodes of
this network. The 10/100BaseT and Data Communication Channel (DCC) provide the
physical connection between the nodes.
DCN physical components
The figure below illustrates a Data Communications Network (DCN) as defined by the
Open Systems Interconnection (OSI) model. This figure refers to the physical
components and connections in the DCN. It does not give information on the logical
configuration of the DCN.
