The FarSync X25 T4Ue PCIe card provides 4 high performance X.25 communications lines for Linux and Windows systems.
The FarSync X.25 T4Ue 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.
Features under Linux:
- The T4Ue card installs seamlessly as a plug and play device under the popular Linux 32 and 64 bit distributions. The card supports Linux kernel version 2.6 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 line are supported as standard or up to 4095 connections using the FarSync X25 High Capacity Pack.
- FarSite is committed to supporting the FarSync X25 T4Ue 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 T4Ue card installs seamlessly as a plug and play device under Windows 7, Vista, XP, Server 2003 and Server 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 4095 connections can be supported using the FarSync X25 High Capacity Pack or 254 per line 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. 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 T4Ue 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
- PC/Server based X.25 switch and an XOT Option
The card is compatible with all public X.25 networks, such as Datex-P, BT X.25 Direct, Eirpac, Austpac, Transpac and Itapac to name just a few.
The FarSync X25 T4Ue 4 line card runs an AMD processor with SRAM and an embedded HDLC controller connected to the Server/PC through a PCIe bus.
The 4 line multi function drivers support X.21 (V.11), V.35, RS232 (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.
External (line generated) clocking is supported. The T4Ue also supports card generated clocks speeds from 9600 baud to 8.192 Mbits/s, each line can be set to a different speed.
PCIe Bus Specification
The FarSync X25 T4Ue card is suitable for systems with a PCI express x1 (or higher) slot, covering single processor and multi-processor systems. The card is PCI Express Base Specification Revision 1.0a compliant.
The drivers supplied with Windows and Linux allow large numbers of lines to be supported by the installation of multiple FarSync X25 T4Ue cards in a Server. The card limit is only dependent on the PCIe slot count and resources available in the host Server.
The IP over X.25 support is included as part of the FarSync X25 T4Ue 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.
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.
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.
An optional high capacity pack is available for the FarSync X25 T4Ue. 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 T4Ue 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 cable and connector configurations available for the FarSync X25 T4Ue 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.
The X.25 software firmware, drivers, utilities and the X.25 Developers Toolkit are all included on the CD-ROM supplied with the FarSync card. Cables are ordered separately.
The CD-ROM supplied with the FarSync X25 T4Ue includes:
- Drivers for Linux, Windows 7, Windows XP, Vista, Server 2003 and Server 2008
- Numerous example applications with source code
- Documentation for all the APIs in Adobe PDF format
