CARP Data Streamer

Somerdata Ltd has added a real-time high-speed streamer to its product range.
Based on the successful CARP product family, the new CARP Streamer allows multiple sources of network data to be converted to real-time continuous data.
Aimed at the Communications Test and Development markets, CARP Streamer enables pre-set test patterns, files or streaming data from multiple simultaneous network sources to be converted to real-time data at any rate between 150kbps and 622Mbps.
The unit includes multiple real-time synthesised clock sources to provide individual stream clock rates and the ability to slave to individual external clock sources for exact system synchronisation.
Typical applications include satellite downlink simulation, communications stress testing and re-construction of communication link faults.
CARP Streamer operates by mapping data from any TCP/IP port to a designated output data stream and includes sufficient buffering and rate control circuitry to ensure continuous output data flow.
The first version supports up to four simultaneous outputs with a maximum of 155Mbps per stream subject to an aggregate maximum of 622Mbps. Variants include Eight stream and Single stream 622Mbps versions
Setup control and configuration is via a separate 10/100 Ethernet port allowing Data and Control network separation to be maintained.

The TDM version includes E1/T1 TDM streaming, up to 8 E1/T1 streams can be created simultaneously from network streamed data or data files. In this version, E1/T1 data streams recorded as files or streamed over TCP/IP networks are converted to real-time TDM streams, synchronisable to the TDM network.
