Synchronous network establishing method and apparatus
First Claim
1. A synchronous network establishing method of establishing a synchronous network in which a node apparatus conforming to a first scheme and a node apparatus conforming to a second scheme co-reside, wherein the first scheme and the second scheme implement different synchronous state indication codes for establishing the synchronous network, said method comprising the step of:
- converting a first synchronous state indication code that is supplied from the node apparatus conforming to one of the first scheme and the second scheme into a second synchronization state indication code for the node apparatus conforming to the other one of the first scheme and the second scheme.

Abstract
A method of establishing synchronization in a network including a node apparatus conforming to a first scheme and a node apparatus conforming to a second scheme is disclosed. The first scheme and the second scheme implement different synchronous state indication codes for establishing the synchronous network. By converting a synchronous state indication code from a node apparatus conforming to one scheme into a synchronous state indication code suitable for a neighboring node apparatus conforming to the other scheme, a node apparatus conforming to one of the schemes can be cascaded into a network conforming to the other scheme, and network synchronization can be established.
