Abstract
A single node is constituted by a core node that carries out overall management of the node and extended nodes that are connected by transmission lines to the core node. The core node comprises: an Operation Administration & Maintenance (OAM) function part for managing the extended nodes; N common function parts for receiving and outputting by way of transmission lines OAM signals generated by the OAM function part and main signals, and an aggregate-side interface. The extended nodes each comprise individual interfaces and a common function part for processing main signals and OAM signals that are communicated over the transmission lines. The core node and extended nodes are each arranged in appropriate locations and are each housed in individual cases.
Claims34
A distributed network node of a network, in which said distributed network node, said distributed network node comprising:
- a core node and a plurality of extended nodes;
- said core node comprising:
- an Operation Administration & Maintenance (OAM) function part for generating OAM signals used to manage said extended nodes;
- and
- a common function part for carrying out the processes of transmitting and receiving main signals to and from both the network and said extended nodes and transmitting and receiving the OAM signals to and from said extended nodes,
- each extended node comprising:
- an interface function part for carrying out interface processing for that extended node;
- and
- a common function part for processing main signals and OAM signals received from said core node.
