Title:
MODULAR SWITCH SYSTEM ON HIGH-SPEED SERIAL BUS
Document Type and Number:
WIPO Patent Application WO2004051682
Kind Code:
A3
Abstract:
A modular switch system linking on a high-speed serial bus mainly relies on a host machine connector (10) to connect with independent functional modules (20) which provides different functions of a PBX switch module processor such as internal line exchange, external line exchange, voice recording and backbone support. Under such conditions, each functional module (20) becomes a node in a local network, so that these nodes can be interconnected with each other for simultaneous signal transmission. Each functional module (20) possesses a card slot (21), an interface controller (23), a microprocessor (22), and a power supply (24). In the closed network architecture, the data transfer rate and the processing speed of the system can be substantially improved. Furthermore, the system also allows for hot plug-in, expandability, and flexible configuration.
