FarSync T2Ue - Product Details
The FarSync T2Ue 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 T2Ue cards in a Server. Typically 12 or more cards can be supported; the card limit is only dependent on the PCI Express slot count and resources available in the host Server and the total bandwidth of the PCIe bus.
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. 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 T2Ue 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 Express Bus Specification
The FarSync T2Ue complies with the PCI Express Base Specification Revision 1.0a
The FarSync T2Ue installs seamlessly under Linux kernel series 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 synchronous (HDLC framed) data, and transparent bitstream data in signal mode NRZ.
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.
The FarSync T2Ue 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.
