Technical Spec´s WAN T2U *

© Farsite Communication Ltd. • 2012

Overview

The FarSync T2U card and software is designed to provide high performance hardware communications solutions for business, government and the military who need a Universal PCI synchronous communications card. The product includes a low level driver that allows access to the communications features available in the hardware. The card can optionally use the host's standard TCP/IP protocol stack to allow access to IP based networks such as the Internet. The FarSync SDK provides a Developers Toolkit for the product.

The card will support a synchronous line at speeds of up to 10Mbits/s continuous. The highly flexible universal network connector supports RS232C, X.21, RS530 (RS422 signalling), RS449 and V.35 network interfaces.

The product is supplied with a 5 year warranty.

Features under Windows:

The Windows based API common to the entire range of FarSync cards/devices is referred to as the FarSync Windows API (FsWinAPI). This is an extension of the MS COMM API and enables, for example, applications developed to support COM ports, to be easily ported to use FarSync support in synchronous modes. This standardization enables the API to also be readily accessible from higher level environments such as .NET, C#, VB etc.

The FsWinAPI provides applications with direct access to the card's communications port/s for bit sync (HDLC) framing and also transparent bitstream operation for video and voice type applications.

The FarSync T2U can also be installed to appear as a NDIS (LAN) interface so it can simply use the TCP/IP stack over PPP to allow access to IP based networks such as the Internet.

The card installs seamlessly under Windows 7, Windows XP, Vista, Windows Server 2003 and Windows Server 2008 on both 32 and 64 bit, single and multi-core systems. The FarSync drivers are signed by Microsoft for easy installation.

LabVIEW applications can access this adapter.

Features under Linux:

The Char I/O API provides a programming language independent, high-level interface to the FarSync base driver it supports access to all the cards modes of operation. The card can also use the TCP/IP stack to allow access to IP based networks such as the Internet.

The T2U card installs seamlessly as a plug and play device under the popular Linux 32 and 64 bit distributions. The cards supports Linux kernel version 2.6 and 3.0 in 32 and 64 bit formats, including the leading distributions supplied by Redhat, SuSE, Mandriva, Debian, Ubuntu, Fedora, Slackware and more. Multi-processor systems are supported.

FarSite is committed to supporting the FarSync T2U on new versions of Linux and Linux kernels as they are released. The source code for the driver is supplied with the product allowing rebuilding by the end user for use with almost any of the current or future Linux variants.

MikroTik Router:

The FarSync T2U may be installed and used in the MikroTik router products as a multi port synchronous line card.

Developers Toolkit:

The FarSync SDK provides a Developers Toolkit with full documentation, useful utilities, such as a line monitor, and many sample applications for Linux and Windows.

        • HDLC framing support for non standard or specialist protocols

FarSync T2U – Product Details

The FarSync T2U is supplied with software drivers for Windows and Linux. This includes a low level driver that allows access to the communications features available in the hardware and an optionally installable driver that connects with the standard TCP/IP protocol stack to allow access to IP based networks such as the Internet.

The drivers supplied with Windows and Linux allow large numbers of ports to be supported by the installation of multiple FarSync T2U cards in a Server. Typically 12 or more cards can be supported; the card limit is only dependent on the PCI / PCI-X slot count and resources available in the host Server and the total bandwidth of the PCI bus.

Card Hardware

The 2 port card runs an AMD processor with SRAM. The card has a dual embedded HDLC / transparent controller with SDMA access (128 buffers per port) and a wide range of timers. The whole memory space may be mapped via the PCI interface to the PC/Server. Total bandwidth supported by the card is 40 Mbits/s.

Network Interfaces

The multi function line drivers available on both ports support X.21 (V.11), V.35, RS232C (V.24, X.21bis), RS530 (EIA530, RS422), RS449 (RS422) , network interfaces, all soft configurable and ESD protected from static charges. The maximum supported line speed is 10 Mbits/s full duplex.

Clock Generation

As well as external clocking the T2U supports card generated clocks at a range of standard frequencies from 9,600 baud to 8.192 Mbits/s and dual clocks can be generated in V.11 mode if required. The clocking speed of both ports is individually selectable.

PCI Bus Specification

The FarSync T2U card is suitable for systems with a PCI or PCI-X bus, covering single processor systems, multi-processor systems and processors featuring HyperThreading technology. The card is PCI revision 2.2 compliant with support for both 3.3 and 5 volt signalling, the power for the card is taken from the 3.3 volt supply rail. The FarSync T2U card may be fitted in either 32-bit PCI bus slots or 64-bit PCI-X bus slots as this Universal PCI card will work perfectly well in both.

Key Features supported on Linux

The FarSync T2U installs seamlessly under Linux kernel series 2.6 and 3.0 on both single and multi-core 32 and 64 bit systems. All the popular distributions are supported including Red Hat, SuSE, Slackware, Ubuntu, Mandriva, Debian and Fedora.

Installation is simple, the driver is dynamically loadable so a kernel rebuild is not required for the driver to be installed. The driver acts as a dynamically loadable module. The link level protocol can be PPP, Cisco HDLC or Frame Relay with optional authentication by CHAP, MSCHAP or PAP (RFC 1334) providing a standard point-to-point network interface. The driver is supplied with source code.

The Char I/O API provides a programming language independent, high-level interface to the FarSync base driver it supports access to bit synchronous (HDLC) framed and transparent bitstream data in NRZ line signal mode. The card can also use the TCP/IP stack to allow access to IP based networks such as the Internet.

A configuration utility is provided to set the line speed, interface type and protocol, after which the ports may be configured with standard networking tools.

Key Features supported on Windows

The FarSync T2U installs easily under Windows 7, Windows Vista, Windows XP, Windows Server 2003 and Windows Server 2008 on single or multi-core 32 and 64 bit systems. A FsWinAPI driver is installed with the optional installation of an NDIS (LAN) driver. The NDIS driver supports TCP/IP running over PPP with optional authentication by CHAP or PAP (RFC 1334) providing a standard point-to-point network interface. The drivers are signed by Microsoft for easy installation.

The product is supplied with a comprehensive configuration utility and its own Line Monitor that allows the user to record, display and store line traffic with WAN protocol decoding for fast debugging.

The FarSync T2U FsWinAPI allows applications developed using the FarSync SDK to exactly control the type of data sent and received in bit synchronous (HDLC framed) data and transparent bitstream formats in NRZ signal mode.

FarSync SDK - The Developers Toolkit

The SDK includes support for writing applications on both Linux and Windows and contains documentation, working sample applications, development and test utility applications. There is everything a user needs to rapidly develop and test a wide variety of applications such as specialist synchronous (HDLC framed) protocols or transparent bitstream data requirements including Audio, MPEG Video T-DMB and DAB ETI with bitstream encoder and decoder. The FarSync SDK is ordered separately from the FarSync T2U.

Configuration

For Windows configuration is by a GUI application

The line can be reconfigured and restarted without reloading the software. There is context sensitive help and an on-line manual should it be required. An advanced tab permits users to further specify the configuration of the line if necessary. For Linux a configuration utility is provided; alternatively text files can be used.
