The Peripheral Component Interconnect (PCI) bus is a motherboard resident bus that provides access to system memory and the host processor at speeds approaching that of the processor's full native speed. All read and write transfers over the PCI bus are burst transfers.
The Cisco ATM PCI Adapter features a compact design that fits conveniently into a single PCI slot (Figure 1-1).
The Cisco ATM PCI Adapter uses an ATM compliant interface that connects to multi-mode fiber or twisted-pair copper topologies. The Cisco ATM PCI Adapter is available in two versions with the distinct difference being the connector type used:
The ATM physical layer interface requires a specific line encoding. Both fiber and copper 155 Mbps adapters support the Synchronous Optical NETwork (SONET) STS-3c Synchronous Payload Frame and SDH Frame formats.
