Product Overview

The intelligent FarSync WAN TE1 card brings comprehensive E1 and T1 support to Linux and Windows. Full bandwidth on unstructured T1 and E1 G.703 lines, T1 and E1 fractional (G.703/G.704) are all supported with easy software configuration.

Whether you are connecting to the Internet, satellite links, private networks using TCP/IP or interconnecting sites using leased lines a FarSync card provides the connectivity solution, replacing standalone routers and firewalls with an integrated solution on a PC/Server.



The card installs seamlessly under Linux kernel series 2.2, 2.4 and 2.6 on both single and multiprocessor 32 and 64 bit systems. The drivers are included as standard in the 2.4 and 2.6 kernels. Distributions by Redhat, SuSE, Slackware, Mandriva, Debian, Ubuntu, Fedora and many more are supported.

The link level protocol under TCP/IP can be PPP (with CHAP, PAP or MSCHAP), Cisco HDLC or Frame Relay. The serial port provides a standard point-to-point network interface controllable with all the standard Linux networking tools.


The card installs seamlessly as a plug and play device under Windows 2000, XP or Server 2003 on both single and multiprocessor systems. The interface to the card is presented as an NDIS (LAN) driver with TCP/IP running over PPP with optional authentication by CHAP or PAP (RFC 1334). FarSync WAN drivers have been validated by Microsoft as 'Designed for Windows XP'.

Both the modern RJ48C (RJ45) connectors and the traditional twin coax are available on the card so if you are not sure what connector type is being used, use the FarSync WAN TE1.

Typical Applications for T1 / E1 cards

The FarSync WAN TE1 card is suitable for connection to TCP/IP networks on Windows and TCP/IP and Frame Relay networks on Linux. Typical applications include:

  • High speed Internet Access
  • Internet access over Frame Relay
  • Remote office access over leased lines
  • Server-based network hub (Routers & Firewalls)
  • Integration with embedded Linux based Products
  • Satellite multicasting
  • Video Teleconferencing

In case where it is required to gain lower level access to the E1 / T1 line via an API then the FarSync OEM TE1 should be purchased as it is supplied with a complete Developers Toolkit.

High Performance and Flexibility

The FarSync WAN TE1 is designed for high performance and flexibility. The adapter is driven by an AMD processor with 1Mbyte of on board zero wait state SRAM. The PCI Bus mastering DMA interface provides a very high performance interface to the card whilst minimising PCI and Server CPU loads.

The FarSync WAN TE1, T1U, T2U, T4U and T4E cards can all be intermixed.

PC / Server PCI / PCI-X Bus Compatibility

The FarSync WAN TE1 is PCI version 2.2 compliant and PCI-X compatible, this Universal PCI adapter can operate in PCs using either 3.3 volt or 5 volt signaling. The card is suitable for PCs with both 32 bit bus and 64 bit bus configurations. The power for the card is taken from the 3.3 volt supply rail.

Installation and Configuration



A simple installation procedure will make the device driver available via the standard kernel configuration mechanism. The driver may be either permanently linked to the kernel or used as a dynamically loadable module.

A configuration tool is provided to set line speed, interface and the protocol, after which the ports may be configured with standard networking tools. Examples and default configurations are provided with the on-line documentation. The driver for the adapter is included as standard in 2.4 and 2.6 kernels.


The FarSync WAN TE1 is very quick and easy to install. The product is supplied with an NDIS (LAN) interface that allows the connection to appear to the system as a LAN card. This means that all the configuration complexities are hidden, making for a very quick installation. A configuration application is available to configure the T1 and E1 parameters if required. FarSync WAN drivers have been validated by Microsoft as 'Designed for Windows XP'.

Line Monitoring



The standard Linux utilities TCPDump and Ethereal can both be used to monitor the data traffic on the E1 or T1 line.


Click for sample screenThe product is supplied with a high performance multi-channel line monitor that allows the user to record, display, store and replay line traffic with protocol decoding (see sample screen). Comments can even be inserted into the line trace to assist later analysis.




Product Packaging

The product includes the communications card, RJ48C (RJ45), a 2 metre cable, Windows and Linux driver software (source code is provided for Linux driver), utilities and documentation supplied on CD-ROM. New versions of the software are made available from the support page as they are released.
