Hardware Features

The architecture of the PCI344 capitalizes on the leading edge capabilities of the MPC860MH, Motorola's PowerQUICC®-based datacomm processor. This device is specifically designed as a very high performance, specialized communications controller.

The PCI344 is designed as a fully programmable communications subsystem capable of sustaining high data rates for a variety of protocols used in synchronous data communications.

With software configurable line interfaces, the PCI344 provides either V.35 or RS422 connectivity and the ability to configure on a port-by-port basis.

The PCI344 adapter enhances overall system performance by utilizing its onboard intelligence and a 32MB DRAM array to handle much of the low level communications. 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 PCI344.

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, 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.
