The FarSync X.25 T4Ee product is a high quality X.25 solution for business, government and military applications, it has been developed to provide high performance, versatile X.25 connectivity for Linux and Windows systems. The PCIe card will support 4 X.25 lines at speeds to over 2.048 Mbits/s. The highly flexible universal network connector supports RS232, X.21, RS530, RS449 and V.35 network interfaces. A number of different line signaling methods are handled, including NRZ, plus the self clocking (clock for the data is decoded from the incoming data line) NRZI, Manchester Encoding, Conditioned Diphase (also known as Differential Manchester), FM0 and FM1.
Linux: The Char I/O API provides a programming language independent, high-level interface to the FarSync base driver it supports access to bit synchronous (HDLC) framed, transparent bitstream and asynchronous data. The cards can also use the TCP/IP stack to allow access to IP based networks such as the Internet. It also allows selection of the full range of clock modes. The link level protocol can be PPP, Cisco HDLC or Frame Relay with optional authentication by CHAP, MSCHAP or PAP (RFC 1334) providing a standard point-to-point network interface. The card installs seamlessly as a plug and play device. The driver supports Linux kernel version 2.6 onwards, including the leading distributions supplied by Redhat, SuSE, CentOS, Debian, Ubuntu, Fedora, Slackware and more. Multi-processor systems are supported. The driver is dynamically loadable so a kernel rebuild is not required for the driver to be installed. FarSite is committed to supporting the cards on new versions of Linux and Linux kernels as they are released. The source code for the driver is supplied with the product allowing rebuilding by the end user for use with almost any of the current or future Linux variants. The driver supports both big-endian and little-endian memory storage formats. A configuration utility is provided to set the line speed, interface type and protocol, after which the ports may be configured with standard networking tools.
Windows: The FarSync T4Ee supports a Windows based API, common to the entire range of FarSync cards/devices, it is referred to as the FarSync Windows API (FsWinAPI). This is an extension of the MS COMM API and enables, for example, applications developed to support COM ports, to be easily ported to use FarSync support in synchronous or asynchronous modes. This standardization enables the API to also be readily accessible from higher level environments such as .NET, C#, VB etc. The special clocking features are all accessible though the FsWinAPI. Async operation support is also provided by the Win32 COMM interface as well as FsWinAPI. The FsWinAPI provides applications with direct access to the card's communications port/s for bit sync (HDLC) and bisync framing and also transparent bitstream operation for video and voice type applications. The FarSync T4Ee can also be installed to appear as a NDIS (LAN) interface so it can simply use the TCP/IP stack over PPP to allow access to IP based networks. LabVIEW applications can access this card. The product is supplied with a comprehensive configuration utility, a typical screen is shown. The lines can be reconfigured and restarted without reloading the software. There is context sensitive help and an on-line manual should it be required. An advanced tab permits users to further specify the configuration of the line if necessary. The product is supplied with its own Line Monitor that allows the user to record, display and store line traffic with WAN protocol decoding for fast debugging.
