Long-haul PCI-to-PCI bridge
First Claim
1. A long-haul PCI bridge pier comprising a PCI interface for connection to a PCI bus, a high speed link interface for connection to a high speed link, and a PCI adapter operative to transform PCI information received at said PCI interface into high speed information to be transmitted through the high speed link interface, and operative to transform high speed information received at said high speed link interface into PCI information to be transmitted through the PCI interface, said PCI bridge pier further comprising a non-PCI interface, and a non-PCI adapter operative to transform information received at said non-PCI interface into high speed information to be transmitted through the high speed link interface, and operative to transform high speed information received at said high speed link interface into information to be transmitted through the non-PCI interface.

Abstract
A long-haul PCI bridge pier is provided that comprises a PCI interface for connection to a PCI bus, a high speed link interface for connection to a high speed link, and a PCI adapter operative to transform PCI information received at said PCI interface into high speed information to be transmitted through the high speed interface, and operative to transform high speed information received at said high speed interface into PCI information to be transmitted through the PCI interface. The PCI bridge pier permits remote connection of a PCI bus with a high speed link such as a serial link. Two such PCI bridge piers, in combination with a high speed link may be used for implementing a long haul PCI-to-PCI bridge.
