FarSync X25 T2Ee - The 2 Port X.25 Low Profile PCI Express Card
The FarSync X25 T2Ee PCIe card provides a very flexible 2 port PCI Express low profile X.25 communications platform for Linux and Windows systems
The FarSync X.25 T2Ee 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.
Line signalling modes: NRZ, Manchester encoding, FM0, FM1 and Conditioned Diphase (Differential Manchester) are handled by the onboard FarSite customisable communications controller as well as soft selectable line termination resistance.
The product is supplied with a free 5 year warranty.
Features under Linux:
- The T2Ee 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 to 3.0 and onwards in 32 and 64 bit formats, including the leading distributions supplied by Redhat, SuSE, Mandriva, Debian, Ubuntu, 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 per port are supported as standard or up to 4095 connections using the FarSync X25 High Capacity Pack.
- FarSite is committed to supporting the FarSync X25 T2Ee 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.
Features under Windows:
- The T2Ee card installs seamlessly as a plug and play device under Windows 8.1, 8, 7, Vista, Windows Server 2012, 2008 and 2003. 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 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 4095 connections can be supported using the FarSync X25 High Capacity Pack or 254 per port as standard.
- IP over X.25 support is included permitting TCP/IP operation over an X.25 network.
- 32 and 64 bit applications supported
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. In addition, the Windows product has a toolkit for the LAPB API. A multi-port Line Monitor and a Line Statistics application are also supplied.

The FarSync X25 T2Ee card is suitable for connection to all types of X.25 networks, X.25 over the ISDN D channel and leased lines. Typical applications include:
- Private X.25 networks such as Lottery, Police, Customs, Military, Fishery, Financial, Government and Airline
- E-Commerce gateways for credit verification
- Mixed X.25 and IP networks
- SMS message gateways
- Billing and Mediation
- FTAM access
- ATM connections
- Lottery terminals
- PC / Server based X.25 switch with XOT
The card is compatible with all public X.25 networks.
The drivers supplied with Windows and Linux allow large numbers of ports to be supported by the installation of multiple FarSync X25 T2Ee cards in a Server. Typically 12 or more cards (24+ ports) can be supported; the card limit is only dependent on the resources available in the host Server and the total bandwidth of the PCIe bus.
The FarSync X25 T2Ee 2 port card runs an AMD processor with SRAM with a FarSite communications controller (customisable), connected to the Server/PC through a PCI Express bus.
The multi function line drivers available on both ports support X.21 (V.11), V.35, RS232 (V.24), RS422, RS530 and RS449 network interfaces, all soft configurable and ESD protected from static charges.
Line Signalling Modes
NRZ plus the self clocking (clock for the data is decoded from the incoming data line) line signalling modes Manchester Encoding, Conditioned Diphase (also known as Differential Manchester), FM0 and FM1. This means separate clock lines are not required, these line signalling modes are a soft configurable alternative to NRZ and a reliable way of handling long high speed cable runs.
Line termination is supported on all the balanced pair signals for X.21 (V.11), V.35, RS422, RS530 (EIA530) or RS449 operation. The line termination resistors may be soft selected to be selected on a port by port basis. The addition of line termination resistors helps improve signal quality on long high speed lines.
Terminal Timing is supported to enable system-wide clock synchronisation.
PCI Express Bus Specification
The FarSync X25 T2Ee card is suitable for systems with a PCIe bus, covering single and multi-processor systems. The card is compliant with PCI Express Base specification revision 1.0a and above. The FarSync X25 T2Ee is a bus mastering, 1x (single lane) card.
The IP over X.25 support is included as part of the FarSync X25 T2Ee 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, ISO Transport and accessing HDLC (LAPB). 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.
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 should be ordered at the same time that the FarSync X25 card is purchased, although a retrofit is possible.
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 PC's standard TCP/IP connection such as an Ethernet card.
An optional high capacity pack is available for the FarSync X25 T2Ee. 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 T2Ee is purchased although a retrofit upgrade is possible. One FarSync X.25 High Capacity Pack is required per card. See Order Information.
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.
The Configuration in Linux can also be optionally configured by a text file.
