Hardware Features

The PCI334 is designed as a fully programmable communications subsystem capable of sustaining high data rates for a variety of protocols used in synchronous data communications.

The architecture of the PCI334 capitalizes on the intelligence of Motorola's MC68360 QUICC® datacomm processor, enabling it as a specialized communications controller.

The PCI334 adapter enhances overall system performance by utilizing its onboard intelligence and large DRAM array to handle much of the low level communications that typically burden the host system. The DRAM also eases the downloading of protocols for stand-alone code execution by relegating most of the serial I/O communication related processing to the PCI334.

Extensive Software Support

With a well-defined API, the integrated protocol suite from Performance Technologies reduces time to market by eliminating unnecessary development time at the hardware/protocol level. The protocols for our standard WAN hardware products enable development engineers to proceed directly to integration and application development efforts.

PTI's comprehensive suite of WAN communications protocols provides complete WAN connectivity solutions for Frame Relay, HDLC, LAPD, X.25, SS7, and PPP protocols. Operating system support includes Solaris®, Windows NT®, and Linux®.

For the Solaris® environment, PTI's ComLinkTM Communications Software provides both a transparent link to all SunLink® protocols, as well as a documented set of driver primitives for developing synchronous/serial related applications.
