The FarSync X25 T1U Universal PCI card provides high performance X.25 communications for Linux and Windows systems.
Overview
The FarSync X.25 T1U 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 Universal PCI card will support an X.25 line at speeds to over 2.048 Mbits/s. The highly flexible universal network connector supports RS232C, X.21, RS530, RS449 and V.35 network interfaces.
Features under Linux:
- The T1U card installs seamlessly as a plug and play device under the popular Linux 32 and 64 bit distributions. The card supports Linux kernel versions 2.6.12 onwards in 32 and 64 bit formats, including the leading distributions supplied by Red Hat, SuSE, CentOS, Ubuntu, Debian, Fedora, Slackware and more. SMP (multi-processor) systems are supported. Configuration is by a Java based GUI.
- There are APIs to the X.25 layer, a Sockets based interface and a Java API. There is also an API to the ISO Transport layers (ISO 8073 – connection oriented).
- IP over X.25 support is included permitting TCP/IP operation over an X.25 network.
- XOT (X.25 over TCP/IP) support is available as an option, using the same API’s as X.25. XOT can operate at the same time as X.25.
- Up to 254 connections are supported as standard or up to 4,095 connections using the FarSync X25 High Capacity Pack.
- FarSite is committed to supporting the FarSync X25 T1U on new versions of Linux and Linux kernels as they are released. The source code for the driver and the libraries for the API are 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.
Features under Windows:
- The T1U card installs seamlessly as a plug and play device under Windows 10, 8, 7, Vista, Windows Server 2016, 2012 and 2008. 32 and 64 bit Windows operating systems are supported.
- The X.25 software has a host of features including ISO Transport (classes 0 to 3), support for OpenFT FTAM, a WinSock2 compliant Sockets API, a Java API, a COM Port API and a LAPB layer 2 (HDLC) that is also directly accessible by its own API. The Sockets API is also accessible from .NET applications.
- Up to 4,095 connections can be supported using the FarSync X25 High Capacity Pack or 254 as standard.
- IP over X.25 support is included permitting TCP/IP operation over an X.25 network.
X.25 Developers Toolkit: A comprehensive Developers Toolkit for development using APIs to X.25 and ISO Transport is included with each product covering Linux and Windows. A multi-port Line Monitor and a Line Statistics application are also supplied.

FarSync X25 T1U – Hardware Details
The FarSync X25 T1U 1 port card runs an AMD processor with SRAM and an embedded HDLC controller connected to the Server/PC through an Universal PCI bus.
Network Interfaces
The multi function line drivers support X.21 (V.11), V.35, RS232C (V.24, X.21bis), RS530 (EIA530, RS422), RS449 (RS422), network interfaces, all soft configurable and ESD protected from static charges. Line speeds to over 2.048 MBits/s are supported.
Clock Generation
External (line generated) clocking is supported. The T1U also supports card generated clocks at 9600, 19200, 38400 and 76800 baud speeds. Note: if a wider range of card generated clock speeds are required the FarSync X25 T2U should be used instead.
PCI Bus Specification
The FarSync X25 T1U card is suitable for systems with a PCI or PCI-X bus, covering single processor systems, multi-processor systems and processors featuring HyperThreading technology. The card is PCI revision 2.2 compliant with support for both 3.3 and 5 volt signalling, the power for the card is taken from the 3.3 volt supply rail.
The FarSync X25 T1U card may be fitted in either 32-bit PCI bus slots or 64-bit PCI-X bus slots as this Universal PCI card will work perfectly well in both.
TCP/IP over X.25
The IP over X.25 support is included as part of the FarSync X25 T1U product and is integrated into Linux and Windows.
Linux Features: IP over X.25 support complies with RFC 1356 (IP over X.25). Higher level protocols that run over IP including TCP, UDP, HTTP and FTP are supported.
Windows Features: The IP over X.25 support complies with RFC 1356 (IP over X.25), for single and multiple X.25 destinations. Higher level protocols that run over IP including TCP, UDP, HTTP and FTP are supported.

APIs and X.25 Developers Toolkit
Application developers have a choice of APIs for X.25 and ISO Transport. An API selector guide is provided to assist the developer in choosing the most appropriate interface. The comprehensive Developers Toolkit is included with the product.
X.25 Developers Toolkit and API details
FarSync XOT Extension option
For Linux the XOT extension allows applications using the same API to transmit data over XOT (X.25 over TCP/IP). TCP/IP is normally routed over Ethernet on PCs and Servers. The XOT support is compatible with FarSite’s FarLinX X25 Gateway and also other manufacturers XOT products. The XOT and X.25 interfaces can be used simultaneously.
The FarSync XOT Extension for Linux should be ordered at the same time that the FarSync X25 card is purchased, although a retrofit is possible.
Notes:
There is also FarSync XOT Runtime software for Linux available that allows XOT to run over the PCs standard TCP/IP connection such as an Ethernet card.
For Windows there is FarSync XOT Runtime software for Windows available that allows XOT to run over the PCs standard TCP/IP connection such as an Ethernet card.
FarSync X.25 High Capacity Pack option
An optional high capacity pack is available for the FarSync X25 T1U. The FarSync X.25 High Capacity Pack allows up to 4,095 simultaneous connections to be made; a huge increase from the standard 254 on each line. The expanded capacity applies to SVC, PVC and ISO Transport connections.
Customer applications developed to use the standard X.25 Sockets API are compatible with the FarSync X25 High Capacity Pack.
The FarSync X.25 High Capacity Pack is available for Windows and Linux, it should be ordered at the same time that the FarSync X.25 T1U is purchased although a retrofit upgrade is possible. One FarSync X.25 High Capacity Pack is required per card. See Order Information.

Configuration
For both Windows and Linux configuration is by a GUI configuration application, rapid installation and easy configuration are key features of the product. See sample screens below.
The X.25 line can be reconfigured and restarted without reloading the software.
Many of the parameters such as DTE / DCE selection are determined automatically. Selecting the line speed by default automatically sets suitable timer and retry values. An advanced tab permits users to exactly specify the configuration of the line if necessary.
Cables
The cable and connector configurations available for the FarSync X25 T1U are described in the FarSync product range and compatible cables table. Crossover cables or DTE to DCE conversion cables also sometimes referred to as null modem cables, are also available.
