The FarSync X25 T4Ue PCIe card provides 4 high performance X.25 communications lines for Linux and Windows systems. A PCI bus version is also available.
The FarSync X.25 T4Ue product is a high quality X.25 solution for business, government and military applications, it has been developed to provide high performance, versatile X.25 connectivity for Linux and Windows systems.
The PCIe card will support 4 X.25 lines at speeds to over 2.048 Mbits/s. The highly flexible universal network connector supports RS232, X.21, RS530, RS449 and V.35 network interfaces.
A PCI version of the adapter, the FarSync X25 T4U is available too.
Features
The 4 port card comprises an AMD processor with SRAM. The whole memory space may be mapped via the PCIe interface to the PC/Server. The adapter has a quad embedded HDLC / transparent controller with SDMA access (128 buffers per port) and a full range of timers. Total bandwidth supported by the card is 64 Mbits/s.
The multi function line drivers available on all the ports support X.21 (V.11), V.35, RS232 (V.24, X.21bis), RS530 (EIA530, RS422) and RS449 network interfaces, all soft configurable and ESD protected from static charges.
The maximum supported line speed is 10 Mbits/s full duplex.
As well as external clocking the adapter supports card generated clocks at a wide 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 all ports is individually selectable.
- PCI Express Bus Specification
FarSync PCIe cards are suitable for systems with a PCIe bus, covering single and multi-processor systems. These cards are compliant with PCI Express Base specification revision 1.0a and above. The FarSync adapters are bus mastering, 1x (single lane) cards.
The drivers supplied with Windows and Linux allow large numbers of ports to be supported by the installation of multiple FarSync cards in a Server. Typically 12 or more cards (24+ ports) can be supported; the card limit is only dependent on the resources available in the host Server and the total bandwidth of the PCIe/PCI/PMC bus.
