FarSync WAN X.21 / V.35 universal PCI / PCI-X intelligent cards provide versatile high performance synchronous connectivity to the Internet, satellite connections or to corporate networks over leased lines
The FarSync WAN T-Series product datasheet for Linux in Acrobat PDF format may be downloaded here.
The versatile intelligent FarSync WAN T-Series cards provide up to 10 Mbits/s per port WAN solutions for your X.21, V.35 and RS530 connectivity requirements. Whether you are connecting to the Internet, satellite links, private networks using TCP/IP or connecting sites using leased lines, FarSync cards provide the connectivity solution, replacing standalone routers and firewalls.
The cards install seamlessly under Linux kernel series 2.4 and 2.6 on both single and multiprocessor 32 and 64 bit systems. The drivers are included as standard in the kernel. Distributions by Redhat, SuSE, Slackware, Mandriva, Debian, Ubuntu, Fedora and more are supported.
The link level protocol can be PPP, Cisco HDLC or Frame Relay. Each serial port provides a standard point-to-point network interface controllable with all the standard Linux networking tools. Multiple cards can be installed to create a very low cost high speed Wide Area Network (WAN) hub.
PC connections to secure BRENT units are supported using X.21.
T1 and E1 (G.703 and G.704) connections are supported using the FarSync WAN TE1 - E1 / T1 card.

The FarSync WAN T-Series X21 / V35 adapters are suitable for connection to TCP/IP networks and HDLC lines. Typical applications include:
The T-Series intelligent adapters have been designed for high performance and flexibility. The cards are driven by a AMD processors with 1 Mbyte of on board zero wait state SRAM. The PCI Bus mastering DMA interface on the FarSync T1U, T2U and T4U provides a very high performance interface to the card whilst minimising PCI and PC CPU loads.
The FarSync WAN TU1, T2U and T4U are 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.
A large number of ports can be supported by the installation of multiple FarSync cards in a PC. The T1U, T2U and T4U cards can be intermixed. Rack mounted Servers can support 12 or more cards (48+ ports) utilising more than one PCI bus, the card limit is only dependent on the resources available in the host server.
Where an Application is required to interface to API supporting HDLC or transparent bit stream formats the FarSync OEM range of cards should be used.
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.
For kernel versions 2.2.21 and 2.4.9 and above the drivers are included as standard.
A daemon is included that allows the signals on any or all ports to be automatically monitored. The network interface associated with a specific port can then be brought up or down to reflect the line state. This allows routing tables to be dynamically recalculated to reflect destinations actually available.
The cable and connector configurations for each card type are described here. The FarSync WAN T-Series product range table lists the cables available for each card type. Crossover cables, sometimes referred to as null modem cables, are also listed.
The product includes the communications card, driver software (with source), utilities and documentation supplied on CD-ROM. The cables are ordered separately see FarSync WAN cables for details.
