The FarSync TE1e intelligent PCIe card provides an API to allow access to E1 G.703 and fractional E1 G.704 connectivity for Linux and Windows systems. A PCI version is also available.
The intelligent FarSync TE1e card brings comprehensive E1 support to Linux and Windows to allow your application full access to the E1 features available on the card. Full bandwidth on unstructured E1 G.703 lines, 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 FarSync SDK provides the 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 300 799) and STI (Service Transport Interface – ETSI EN 300 797) using the BNC connectors.
A general purpose bitstream encoding and decoding library including DAB-ETI (NI, G.703) and DAB-STI (PI, G.703), support to reduce application development timescales is available with the FarSync SDK.
Both the RJ48C (RJ45) and twin coax (BNC) connectors are available on the card so if you are not sure what connector type is going to be required, use the FarSync TE1e.
An external clock input of up to 10mhz through a SMA connector is supported to allow synchronisation of the output data clock, to, for example, a GPS source.
A PCI version of the card is also available, see the card hardware section.
Features
Both PCIe and PCI E1 cards comprise an AMD processor with SRAM. The whole memory space may be mapped via the PCIe interface to the PC/Server. The card has an embedded HDLC / transparent controller with SDMA access (128 buffers per port) and a full range of timers.
The cards support 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.
E1 Modes: HDLC-framed or transparent data over G.703 unframed/unstructured or G.703/G.704 framed/structured Double frame and CRC4 multiframe modes.
- External Synchronisation Clock
Frequency: 10MHz, 5MHz, 2.048MHz, 1.544MHz or 1MHz.
Frequency Tolerance: Within 30ppm or better of supported speeds
Input Impedance: 75 ohms
Input Level:
Absolute Max: -7.5V to +12.5V
Typical: +/- 300 mV with a hysteresis of 50mV or G.703-13
Typical: HCMOS, square or sine wave
The external synchronisation clock feature is not available on the FarSync Te1 (PCI card).
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.
- 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.
FarSync PCI cards comply with the Universal PCI (PCI-X compatible, PCI v2.2 compliant) specification. These bus mastering cards are suitable for systems with a PCI bus, covering single and multi-processor systems.
