Communications-oriented computer system backplane including a PCI input/output bus for transmission of address, data, and control information, and a time-domain multiplexed signal bus (TDMSB) for transmission of high-speed digitized signal information

摘要

A communications-oriented computer system backplane including an input/output bus for transmission of address, data, and control information, the input/output bus including a plurality of expansion slot module connected to the input/output bus for the connection of I/O logic cards; and a time-domain multiplexed signal bus (TDMSB) for transmission of high-speed digitized signal information, the time-domain multiplexed signal bus including a plurality of expansion slot modules connected to the time-domain multiplexed signal bus for the connection of high-speed digitized signal logic cards. The expansion modules associated with the two busses are aligned to facilitate interconnecting the input/output bus with the time-domain multiplexed signal bus for transmitting data therebetween.
