FarSync Flex X25 - The X.25 USB Adapter
The FarSync Flex X.25 USB adapter has been developed to provide high performance X.25 communications for Linux and Windows systems.
Overview
The FarSync Flex X.25 adapter 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 bus powered USB adapter will support an X.25 line at speeds of up to 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 Flex adapter installs seamlessly as a plug and play device under the popular Linux 32 and 64 bit distributions. The USB adapter is supported on 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 are supported as standard or up to 4095 connections using the FarSync X25 High Capacity Pack.
- FarSite is committed to supporting the FarSync Flex X25 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 Flex adapter installs seamlessly as a plug and play device under Windows 7, Windows XP, Server 2003, Server 2008 and Vista. 32 and 64 bit Windows operating systems are supported. Multiple Flex's can be installed.
- 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 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.
Typical Applications
The FarSync Flex adapter 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
- Control applications requiring a HDLC link
- Lottery Terminals
- ATM connections
- X.400
- PC / Server based X.25 switch with XOT
The adapter 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.
Key Features
The intelligent FarSync Flex X.25 has been designed for easy installation and to provide high performance in a variety of environments. The Flex adapter uses an ARM processors with Flash for the on board code.
- 254 simultaneous SVC and PVC virtual connections or 4095 per port using the High Capacity Pack
- XOT (X.25 over TCP/IP) support available as an option on Linux
- Over 2,000 x.25 packets per second
- Line speeds of up to 2.048 Mbits/s
- Network interfaces for X.21 (V.11), V.35, RS232C (V.24, X.21bis), RS449, RS530 (EIA530, RS422)
- USB 2.0 high-speed mode (480mb/s) and 1.1 compatible
- High efficiency, USB Bus powered, energy saving design
- Internal and external line clocking
- Dual bank flash for secure in field upgrades and previous system restore capability
Configuration
For both Windows and Linux configuration is by a GUI configuration application, see a samples screens below.
The X.25 line can be reconfigured and restarted without reloading the software and the Flex supports hot plug in.
There is context sensitive help and an on-line manual should it be required. 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.
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.
X.25 Developers Toolkit and API details
TCP/IP over X.25
The IP over X.25 support is included as part of the FarSync Flex X25 product and is integrated into Linux, Windows XP and Server 2003.
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.
See further details about how IP over X.25 works
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 is available under product code FS9508, it 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 Flex X25. The FarSync X.25 High Capacity Pack allows up to 4,095 simultaneous connections to be made, a huge increase from the standard 254. 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 under product code FS9504 for Windows and FS9505 for Linux, it should be ordered at the same time that the FarSync Flex X.25 is purchased although a retrofit upgrade is possible. One FarSync X.25 High Capacity Pack is required per Flex device.
