E1SS-2040 creates two  identical pairs of  outputs from a single pair of  E1 bitstreams.

The source stream connection is made through two BNC connectors that are hard-wired in parallel and the original bitstreams are routed through the Splitter without any in-line circuitry or delay.  Streams to be monitored are tapped off, buffered and re-constituted to form copies of the orignals on two identical pairs of BNC connectors.

Monitoring, recording and other equipment can be connected or disconnected at the outputs without disturbing thesource bitstream, even when the Splitter is unpowered.

The unit is AC powered and supplied in a 1U rackmount case.

E1SS-2040 is part of the E1SS product range, which also includes a programmable Router for E1/PRI distribution, monitoring and recording applications.

CARP Data Capture Gateway

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.

CARP Streamer Data Sheet (pdf)
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.
Streaming E1/T1 TDM data over TCP/IP (pdf) gives more details.

Somerdata Ltd has added 4 channel 1:2 active optical OC-3 and OC-12 splitters to its range of  Communication products.

Aimed at the high-end intercept probe and signal monitoring markets, the units allow multiple 1310 nm OC-3 and OC-12 signals to be split into two paths without degradation. The original signal can be passed through to its destination and a copy sent to other equipment for line quality monitoring,  routing  and probing purposes.

The unit is supplied in a 1U rack-mount configuration with   SC connectors as standard and is part of a range of high-end splitters that will add OC-48 capability this year.

CARP Data Capture Gateway

CARP-0400 Series captures up to 12 input streams for distribution via Gigabit Ethernet for real-time processing & analysis applications.

Applications include Grooming and Filtering, Network Probes, Surveillance Systems, Forensic communications analysis and protocol analysis. The following input modules are available.

• • 4-stream LVDS serial data + clock – 100 kbits/s to 60 Mbits/s
• • 4-stream RS-422A serial data + clock – 20 kbits/s to 15 Mbits/s
• • 4-stream E1/PRI (G.703/G.704) – 2048 kbits/s

Modules can be specified in any combination of the above, up to the maximum of 3 modules.

Each LVDS and RS-422A input can be set to operate with user-specified framing (byte-alignment), or unframed data.

Each E1/PRI input can be set to operate with G.704 framing, or unframed.

Data Distribution

Input streams are distributed over the user’s Gigabit Ethernet data network using TCP/IP protocol.

The target IP addresses are set via the 10/100MHz Ethernet Control and Status Port. Any combination of individual and group IP addressing is supported for transferring data to one or more workstations.

CARP associates individual source port numbers to each input stream. Data streams are transferred once the receiving workstations have open socket connections to one or more source ports and provide the destination port for each stream.

ETDT – Ethernet Splitter/Buffer

ETDT Ethernet Splitter/Buffer provides a means of non-intrusively monitoring and capturing traffic flowing in both directions of a 100MHz LAN connection.

The port connections are made through two RJ-45 connectors that are hard-wired in parallel. All network traffic is passed-through the Splitter/Buffer and monitoring equipment can be connected/disconnected without disturbing network activity.

Ethernet signals are split and fed into a high-impedance buffer that loads the line signals by less than 0.1dB. Low-impedance outputs allow the monitoring equipment to be located up to 50m away from the line connection.

The use of precision op-amp eliminates the distortion and magnetic susceptibility problems associated with transformer coupled adapters.

ETDT operates from +6v to +12V DC power. UK and European AC power adapters are available as options.

E1DT - E1/T1 Data Tap/Buffer

E1DT E1 Active Data Tap/Buffer provides a means of monitoring and capturing traffic flowing in both directions of a 2Mbits/s E1/PRI (G.703/G.704) communications link.

The line connections are made through two RJ-45 connectors that are hard-wired in parallel. All line activity is passed-through the Data Tap/Buffer. Monitoring and recording equipment can be connected or disconnected without disturbing the line.

Line signals are split and fed into high-impedance buffers that load the line signals by less than 0.1dB. Low-impedance outputs allow the monitoring equipment to be located up to 50m away from the line connection.

The design ensures that there is no interruption of the line signals when the Splitter/Buffer is unpowered. All connections are transformer coupled for line isolation.

LED indicators are provided for power and signal presence at each monitor output connector.

E1DT operates from +6v to +12V DC power. UK and European AC power adapters are available as options.

Two versions are available as follows:

• E1DT-ASSY-0058 provides the monitor outputs on a single RJ-45 connector (pins 1/2 and 4/5) for use with devices that monitor both Tx and RX on the same input connector.
• E1DT-ASSY-0059 provides the monitor outputs on two RJ-45 connectors (pins 1 & 2) for use with devices that monitor Tx and RX on two input connectors, including the SomerData E1/PRI Data Capture Card.
• Please note the units are NOT intended for connection to PTT lines where regulatory compliance is required.

R2D3 LVDS/RS-422A Data Capture Card

R2D3 PCI data capture cards 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.

The LVDS card supports serial data + clock transfers at sustained rates up to 60 Mbits/s and the RS-422A card supports serial data + clock transfers at sustained rates up to 15 Mbits/s.

With the appropriate control and application software R2D3 can be used to record, replay and monitor real-time signals, with real-time data being transferred to or from disk or system memory.

Data can be recorded on standard PC fixed or removable hard disks.  Once captured, the bitstream is available for processing or storing-to-disk as 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.

Applications include phone and data  intercept, radar recording, broadcast DAB/DMB data generation, telemetry recording and data multipleers.

LVDS and RS-422A Cards are available as part of a PC-HSR High-Speed Recorder. Transportable and rack-mounting Recorders provide many  hours recording to disk on a standard PC-based workstation.
