Development and installation of network equipment and network systems requires measuring network performance and evaluating QoS. In addition, network operations and maintenance requires monitoring in-service traffic, latency, and frame arrival time variation (frame-jitter) with prompt troubleshooting. The MD1231A addresses all these needs by providing wire-speed performance testing, network monitoring, and full protcol capabilities in one lightweight portable instrument.
The MD1231A provides most of the same well regarded Ethernet and IP performance testing and measurement capabilities of Anritsu’s MD1230B, yet its light weight (5 kg or 11 pounds) and built-in pointing device meet the most stringent field portability requirements of service providers and enterprise network managers. The MT7407A Multislot Chassis supports the same interface modules as the MD1231A and MD1230B in a 14 slot rackmount enclosure.
The MD1231A's two interface slots accept standard MD1230B 8-port 10/100 Mb or 2-port 1 Gb Ethernet interface modules and offer the same unique Ethernet in-service (pass-through) mode monitoring capability. MD1231A also supports 155M/622M PoS modules. Its built-in GPS receiver option provides end-to-end network latency measurements with 1 µsec. resolution for crucial voice and video over IP applications. The Decode Module and Expert Analysis Module options Powered by Sniffer Technologies provide exceptional troubleshooting and protocol decode abilities whose benefits the networking industry has long acknowledged for providing faster network problem solving.
The new MD1231A1 is similar to the MD1231A but adds support for 10 Gb Ethernet and 2.5G/10G PoS modules.
