Description

ABSTRACT:
A communication system containing a plurality of node elements. Each node element contains: a main communication unit containing a multiplexer/demultiplexer unit, a management control unit, a data input/output terminal unit, a switch unit, a connection mode control unit, and a link establishing unit. The connection mode control unit connects the data input/output terminal unit to either the management control unit in its own node element or another management control unit in another remote node element, by controlling the switch unit. The link establishing unit establishes a link for the data input/output terminal unit to access the management control unit in another remote node element through an overhead channel between the node elements. When a request for access to the management control unit in its own node element is made from the remote node element, the connection mode control unit connects the data input/output terminal unit in the remote node element, and to the management control unit in its own node element, through the above link and the switch unit.
