Abstract
A Local Area Network (LAN) is disclosed in which each node includes means for receiving clock signal information from an external network, which may by way of example be another LAN or a wide area network (WAN), and for generating therefrom clock signals for each node of the local network to accommodate synchronous information exchanges with the external network. Any one of the nodes of the local LAN network may act as a Control Node, and any one of the remaining nodes upon instruction from the Control Node may act as a primary Transmission Node for generating clock signals based upon the external network clock signals for all of the nodes of the local LAN network.
