| Overview | |
|
The FarSync X.25 T-Series range of adapters have been developed to provide
very high performance X.25 connectivity for Windows XP, 2000, NT and
Linux (see separate Linux page). The competitively
priced 2 port and 4 port PCI cards in the range are capable of driving
each line at speeds of up to 8.448 Mbits/s (E2) with support for
RS232C, X.21 and V.35 network interfaces. A GUI multi-port Line Monitor and a Line Statistics application are included with the product. |
|
|
|
| Typical Applications | |
|
The FarSync X25 T-Series PCI adapters are suitable for connection to
all types of X.25 networks, X.25 over the ISDN D channel
and leased lines. |
|
|
|
| APIs for Application Development | |
| Application developers have a choice of of 2 APIs for X.25
and 1 for HDLC. An API selector guide is provided to assist the developer
in choosing the most appropriate interface. The developers toolkit is included with the product, This contains sample applications and full documentation to fast track your development process. Free email and telephone support is provided to application developers. |
|
| COM Port API | NCB API |
| This interface provides a very quick and easy to use interface to X.25. Each X.25 session is represented by a COM Port controlled by AT commands. The COM Port API is particularly suitable for applications developed in Visual Basic and similar languages or for those not familiar with X.25. Full documentation and a sample application is provided. | A very flexible and powerful API, allowing access to the low level features of X.25 whilst also enabling easy development. The API is particularly suitable where a large number of sessions are required or where close control over the X.25 layer is required. The comprehensive manual documents the function call definitions and provides helpful advice on the best way to utilise the API. As well as example applications in C the interface structures are also provided in Pascal to permit easy interfacing for applications developed in Delphi. |
| HDLC API | |
| Easy to use API to access Lapb (HDLC layer 2). This interface allows X.25 layer 3 to be completely bypassed. HDLC is frequently required by control and statistics gathering applications to connect to equipment on local or leased lines. An example application in C is provided. | |
|
|
| TCP/IP over X.25 | |
| The IP over X.25 support is included as part of the FarSync X25 product, the particular features support vary between operating systems, these are detailed below. | |
| Windows XP and 2000 | Windows NT |
|
The IP over X.25 support is fully integrated into Windows XP and 2000.
Configuration is performed using standard Network configuration menus. |
For Windows NT an IP/X25 module is supplied to run the IP protocol over the X.25 network. Higher level protocols that run over IP including TCP, UDP, HTTP and FTP are supported. The module conforms to RFC 1356 to permit interoperation with other devices using IP over X.25. |
| Card Performance | |
|
The intelligent FarSync T-Series cards have been designed with performance
in mind. The card is driven by a 50 MHz AMD Am186 series processors with
1Mbyte of on board zero state SRAM memory mapped to the PC. The software
supports a full set of X.25 features whilst still providing very high
data packet throughput. |
|
|
|
| Fast Installation and Configuration | |
| The cards feature support for Windows XP, 2000
and NT. Fast installation and easy configuration are a feature of the product.
‘Plug and Play‘ is supported on Windows XP and 2000. There is context sensitive help and an on-line manual. 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 should it be required. |
|
|
|
| Utilities | |
| The product includes a multi-port line monitor, an
invaluable tool when testing new applications and commissioning new systems.
Line traces can be displayed in real time, recorded and reviewed with full
protocol decoding, comments can even be inserted in the trace to assist
later analysis. A connection status and statistics utility is also provided. Its functions include the display of the channel connection status and statistics of user data, packet and frame types passed over the X.25 lines. |
|
|
|
| Packaging | |
|
The X.25 software, utilities, IP over X.25 support and the development tool kit are all included on the CD-ROM supplied with the FarSync communications adapter. Cables are ordered separately. New releases of X.25 software for FarSync cards are made available for download. |
