Title:
【発明の名称】データ通信システムのノード内の多リンク層から単一物理層へのインターフェース
Document Type and Number:
Japanese Patent JP2003510974
Kind Code:
A
Abstract:
In a node of a data communication system with a number of nodes, in which data communication system isochronous and asynchronous data is exchanged through a serial data bus structure, multiple link layer interface circuits are coupled to a single physical layer interface circuit. The physical layer interface circuit has an external port through which the physical layer interface circuit is connected to the serial bus structure. The physical layer interface circuit is coupled to the link layer interface circuits through bi-directional switches. A logic circuit controls the bi-directional switches and, in dependence of configuration information stored in configuration registers of the link layer interface circuits and its own programming, the logic circuit controls routing of isochronous and asynchronous data streams from the link layer interface circuits to the physical layer interface circuit, and from the physical layer interface circuit to the link layer interface circuits.
