GB/T 19244-2003 (Information technology -- High performance serial bus) is available as an English-translated PDF.

GB/T 19244-2003 — This standard specifies high-speed, low-cost serial bus. It is suitable for use as a peripheral bus or parallel backplane bus spare bus.

The salient features of this serial bus comprising: a) automatically assigned node address no address switch. b) on the ISDN compatible bit rate variable rate data transmission, the base plate from a TTL 24.

576Mbit/s backplane becomes the BTL 49. 152Mbit/s, and the cable media 98. 304Mbit/s, 196. 608Mbit/s and 393. 216Mbit/s. c) Cable Media allows up to 16 physical connection (cable hops), each hop up to 4.

Bus management to optimize the performance to identify a smaller configuration. d) Includes blocks and a single four -byte read and write, and to provide low overhead, a guaranteed bandwidth services " isochronous " mode bus transaction. e) Support cable media and backplane bus physical layer. f) to ensure equal access to all nodes in the fair bus access mechanism.
