X.25 PCI Sync Card

Dual-Port High Speed Synchronous Board

Zipcom Dual-Port Synchronous Board is truly a perfect solution for complex and versatile high-speed synchronous communication applications, such as X.25, Frame Relay, SS7, and others. You simply need to make use of Zipcom's Sync API functions to develop your own applications to meet your business requires. And then together with the board's cutting-edge hardware components, the Sync Board will be ready for any synchronous applications, such as ATM, Satellite, or KIOSK connectivity.

The HDLC driver provides complete HDLC layer 2 data communications control conforming to CCITT, ITU, and industry standards for layer 2 protocols, including frame formatting, bit stuffing, and error detection. To further aid synchronous developers, the Sync Board uses a simplified configuration and the most straightforward Sync API functions. The package provides complete X.25 protocol communications control conforming to CCITT, ITU; and provides the demo source code for programmer to implement his/her applications to the business needs. The programmers easily implement their application codes by using C/C++, Delphi and Visual Basic to invoke the synchronous Application Program Interface (API).

An onboard RISC CPU, combined with dual-ported memory, effectively reduces the burden of the server CPU, bringing overall performance up to 8 Mbps on each port. This is far beyond T1/E1. The renowned Hitachi SCA (Serial Communication Adapter) is used to convert parallel data to serial data, allowing communication with other devices. Furthermore, both synchronous ports are supported with two independent full-duplex transceivers. An FIFO transmit-and-receive buffer and a four-channel DMAC (Direct Memory Access Controller) work together to enable high-speed transfer between SCA and memory.
