The FarSync X25 T2Ee PCIe card provides a very flexible 2 port PCI Express low profile X.25 communications platform for Linux and Windows systems

The FarSync X.25 T2Ee 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 PCI Express card will support 2 X.25 ports 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.

Line signalling modes: NRZ, Manchester encoding, FM0, FM1 and Conditioned Diphase are handled by the onboard FarSite customisable communications controller as well as soft selectable line termination resistance.


The FarSync X25 T2Ee 2 port card runs an AMD processor with SRAM with a FarSite communications controller (customisable), connected to the Server/PC through a PCI Express bus.

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.

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.

NRZ plus the self clocking (clock for the data is decoded from the incoming data line) line signalling modes Manchester Encoding, Conditioned Diphase, FM0 and FM1. This means separate clock lines are not required, these line signalling modes are a soft configurable alternative to NRZ and a reliable way of handling long high speed cable runs.

Line termination is supported on all the balanced pair signals for X.21 (V.11), V.35, RS422, RS530 (EIA530) or RS449 operation. The line termination resistors may be soft selected to be selected on a port by port basis. The addition of line termination resistors helps improve signal quality on long high speed lines.

Terminal Timing is supported to enable system-wide clock synchronisation.

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.
