| Overview | |
|
The versatile intelligent FarSync T-Series X.21 cards provide up to 8.448 Mbits/s (E2 speed) per port WAN solutions for your X.21 and V.35 connectivity requirements. Whether you are connecting to the Internet, satellite links, private networks using TCP/IP, IPX or connecting sites using leased lines, FarSync T-Series cards provide the connectivity solution, replacing standalone routers. The link level protocol can be PPP, Cisco HDLC. Frame Relay is supported with later versions of the 2.4 kernel. The card installs seamlessly under Linux kernel versions 2.2 and 2.4 on both single and multiprocessor systems. The drivers are included as standard with the kernel in versions 2.4.9 and on. The T-Series cards are supported on Linux distributions supplied by Red Hat, SuSE, Mandrake, Debian and Slackware. FarSite is committed to supporting the FarSync X21 T-Series products on new versions of Linux as they are released. The source code for the driver is supplied with the product. Multiple cards can be installed, to create a very low cost high speed Wide Area Network (WAN) hub. See also support under Windows XP 2000 and NT. Once initialised using the simple configuration tool, each serial port provides a standard point-to-point network interface controllable with all the standard Linux networking tools. G.703 E1, fractional E1 and E2 network connections with BNC or RJ45 (E1 only) connectors are supported using interface converters. |

| Typical Applications | |
| The FarSync T-Series X.21 adapters are suitable
for connecting standard TCP/IP and IPX networks. Typical applications include: High speed Internet
access Frame Relay Internet
access Remote office access
over leased lines PC-based multi-port
wide area network hub (Routers and Firewalls) Satellite multicasting Video conferencing |
|
| Multiple Cards | |
| A large number of ports can be supported by the
installation of multiple FarSync T2P and T4P cards in a PC. In a typical
desktop PC 4 cards can be supported providing up to 16 ports, rack mounted
units such as supplied by Penguin
Computing may be able to support 6 or more cards; the card limit is
only dependent on the resources available in the host PC. |
|
| Application Development | |
| Full source is provided for the Linux device driver and configuration
utility. However for normal application development the standard Linux networking
APIs can be used. All existing IP and IPX applications will work with the
interface. The Linux generic HDLC interface that allows bit synchronous
frames to be sent and received is supported on later versions of the 2.4
kernel.
Free email and telephone assistance is available to applications developers. |

|
| High Performance | |
|
The T-Series intelligent cards have been designed for high performance.
They are driven by 50 MHz AMD Am186 CC/CH processors with 1 Mbyte of on
board zero wait state SRAM memory mapped to the PC, features include: |
|
| 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. For kernel versions 2.4.9 and above the drivers are included as standard,
only the optional utility programs provided with product need to be installed. |
|
| Product Packaging | |
| The basic product includes driver software (with source), documentation supplied on CD-ROM, the communications card and a dual X21 cable. The card with software may also be purchased separately from the cables, see X21 Product Range for details | |
