R2D3® PCI data capture cards follow our successful R2D2® range of ISA cards first introduced in 1997 for E1 data capture and provide the basis for development of software solutions for real-time signal surveillance, monitoring, recording, archiving, analysis and processing applications.
Cards provide access to, and output of, real-time digital signals on a PC. Under software control, bitstreams can be transferred to and from host memory, recorded to disk or replayed from disk.
E1/PRI cards support dual-stream unframed and framed 2,048 kbits/s applications (ITU G.703/G.704), with a choice of 75Ω unbalanced or 120Ω balanced data interfaces via BNC or RJ-45 connectors.
R2D3 cards provide input and output data transfer of complete G.703/G.704 frames, including signalling, framing and alarm information. There is no need to specify data format or protocol since all types of messaging or other signals carried within the 2,048 kbits/s stream are supported.
This capability can be significant where there is a need to capture unknown or different types of data and signalling that may be present on E1, ISDN 30, CEPT-1 or PRI links, including encrypted or multiple timeslot (bonded/strapped) data transfers.
Real-time data can be recorded on standard PC fixed or removable hard disks. Once captured, bitstreams are available for processing or storing-to-disk as frame-aligned or unframed binary data. On-board buffering ensures that there is none of the data loss that is often associated with high-speed data capture on PCs.
SomerData supports OEM, developer and system integrator applications, including the provision of programming information with code examples. For application software development, comprehensive Programmer’s Reference Guides and code examples are available on request.
E1/PRI Recorder and Replayer application software is available for use with R2D3, running under Windows XP/Vista™ or Windows 2000™.
