FarSync TE1 - the E1 (G.703 and G.704) Universal PCI card for Linux and Windows

Product Overview

The intelligent FarSync TE1 card brings comprehensive E1 and T1 support to Linux and Windows to allow your application full access to the E1 and T1 features available on the card. Full bandwidth on unstructured T1 and E1 G.703 lines, T1 and E1 fractional (G.703/G.704), HDLC framed and transparent operation are all supported with easy software configuration. 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 G.703 transparent bitstream option available with the API is suitable for video and voice such as T-DMB (Digital Multimedia Broadcasting), DAB (Digital Audio Broadcasting) ETI (Ensemble Transport Interface - ETSI EN 300 797).

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 going to be required, use the FarSync TE1.

Features under Windows: The product includes support for the Microsoft standard Windows SDCI API, providing 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 card installs seamlessly under Windows XP, Windows Server 2003, Vista 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.

The low level API is based on an extended SDCI interface and supports bit sync (HDLC) framed and transparent bit stream data.

The FarSync TE1 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.

Features under Linux: The low level API is based on the raw socket interface and supports bit sync (HDLC) framed and transparent bitstream data. The TE1 card can also use the TCP/IP stack to allow access to IP based networks such as the Internet.

The TE1 card installs seamlessly as a plug and play device under the popular Linux 32 and 64 bit distributions. The cards supports Linux kernel version 2.4 and 2.6 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 TE1 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.

The product is supplied with a 5 year warranty.

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. Free support from FarSite's Engineering department is provided to customers purchasing the FarSync SDK who have technical questions using the API.

FarSync TE1 Product Details

The FarSync TE1 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.

Card Hardware

The 1 port card runs an AMD processor with SRAM. The card has an embedded HDLC / transparent controller with SDMA access (128 buffers) and a wide range of timers. The whole memory space may be mapped via the PCI interface to the PC/Server.

Network Interfaces

The TE1 supports E1 unstructured (G.703) and Transparent operation at 2.048 Mbits/s, E1 fractional (G.703/G.704) at speeds from 64 Kbits/s to 1.984 Mbits/s, T1 unstructured (G.703) and Transparent operation at 1.544 Mbits/s, T1 fractional (G.703/G.704) at speeds from 64 Kbits/s to 1.536 Mbits/s.

E1 Modes: HDLC-framed or transparent data over G.703 unframed/unstructured or G.703/G.704 framed/structured Doubleframe and CRC4 multiframe modes.

T1 Modes: HDLC-framed or transparent data over G.703 unframed/unstructured or G.703/G.704 framed/structured F4 (FT), F12 (D3/D4, SF), F24 (D5, Fe, ESF) and F72 ( SLC96) modes.

PCI Bus Specification

The FarSync TE1 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 signaling, the power for the card is taken from the 3.3 volt supply rail. The FarSync TE1 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 TE1 installs seamlessly under Linux kernel series 2.4 and 2.6 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 Raw Sockets API allows applications developed using the FarSync SDK to access the full feature set of the hardware, these include bit sync (HDLC framed) data, and transparent bitstream data.

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 TE1 installs easily under Windows Vista, Windows XP, Windows Server 2003 and Windows Server 2008 on single or multi-core 32 and 64 bit systems. A low level SDCI 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 TE1 enhanced SDCI API allows applications developed using the FarSync SDK to exactly control the type of data sent and received in bit sync (HDLC framed) data and transparent bitstream formats.

FarSync SDK - The Developers Toolkit

There is everything a user needs to rapidly develop and test a wide variety of applications such as specialist sync (HDLC framed) protocols or transparent bitstream data requirements including Audio, MPEG Video T-DMB and DAB ETI. The FarSync SDK is ordered separately from the FarSync TE1.

Our Engineering department provides free email and telephone assistance to application developers using the API as part of the package provided when the FarSync SDK is purchased.

Windows SDCI API

The SDCI API allows applications to exactly control the type of data sent and received in both bit sync data and transparent bitstream formats. The SDCI API manual in Adobe PDF format provides a comprehensive set of function call definitions and helpful advice on the best way to utilise the interface. The sample applications for HDLC and bitstream operation are written in C.

HDLC and bitstream data

The SDCI API has been extended to allow applications to exactly control the type of data sent and received in both HDLC framed data and transparent bitstream formats. The SDCI SDK contains everything a user needs to rapidly develop and test applications that include specialist sync protocols or transparent data requirements such as Audio, MPEG Video T-DMB and DAB ETI.

Sample Applications

A number of easy to follow sample applications are provided demonstrating the wide variety of features available with the card.
