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 MD1231A1 addresses all these needs uniquely by providing wire-speed performance testing, network monitoring, and full protcol capabilities up to 10 Gbps in one lightweight portable instrument.

The MD1231A1 provides most of the same well regarded Ethernet and IP performance testing and measurement capabilities of Anritsu?s MD1230B , yet its light weight (13 lb) and built-in pointing device meet the most stringent field portability requirements of service providers and enterprise network managers.

The MD1231A1's two interface slots accept MD1230B Ethernet interface modules and offer the same unique Ethernet in-service (pass-through) mode monitoring capability. MD1231A1 also supports MD1230B PoS modules up to 10G. Its built-in GPS receiver option provides end-to-end network latency measurements with 1 usec. 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 MT7407A Multislot Chassis supports the same interface modules as the MD1231A1 and MD1230B in a 14 slot rackmount enclosure.

The MD1231A is a slightly less expesnive version of the MD1231A1 that does not support 10 GbE or 2.5G/10G PoS modules.

Key application areas include:

• Service providers installing and troubleshooting new Ethernet services in the field and in the lab.
• Networking consulting companies, service companies, outsourced network management companies, and system integrators installing, supporting, and troubleshooting their customers? Ethernet networks.
• End users (universities, research labs, large enterprises, government facilities) supporting and troubleshooting their own internal Ethernet networks.
• Supports Ethernet/IP and SONET/SDH/PoS data rates from 10 Mbps to 10 Gbps
• Compact and lightweight with built-in PC, display, pointing device, and keyboard to meet the toughest requirements for field service applications
• Familiar and user-friendly Windows-based operating interface, with identical GUI on the tester and remote control PCs that enables quicker learning and less-skilledusage
• Transmits, monitors, counts, and decodes many high-level IP protocols, providing Voice over IP (VoIP) test and troubleshooting capabilities and helping solve sophisticated protocol-related network problems that simpler physical layer testers cannot analyze at all
• Optional Decode Module and Expert Analysis Module powered by Sniffer Technologies provide much faster and easier troubleshooting with 400+ protocol decodes and expert network problem analysis up to OSI Layer 7, plus converter for Ethereal protocol analysis
• Unique pass-through (in-service) Ethernet monitoring and protocol analysis at full wire speed
• Unique one-button network device performance testing based on the RFC2544 standard allows users to evaluate routers and switches before making new purchases or installing software upgrades
• Strong MPLS and IPv6 traffic generation and test capabilites meet requirements for next-generation networks
• Worldwide end-to-end network latency measurements with 1 usec. precision provide important capabilities for analyzing and troubleshooting IP voice and video networks and network devices
• Physical interfaces for 10 Mbit/s to 10 Gbit/s
• Uniquely powerful and flexible filter and trigger conditions
