Tektronix Expands VoIP Monitoring Solutions to Enable Service Providers to Deploy, Monitor and Maintain Enterprise VoIP Services
Tektronix' Active Test Solutions Combine with its Monitoring Suite to Enable Total Core-to-Premise Visibility

Tektronix, Inc. , a leading worldwide provider of communications network management and diagnostics solutions, announced the expansion of its assurance suite of VoIP monitoring solutions to include new active test probes and capabilities that enable service providers and cable companies to effectively deploy, monitor and maintain VoIP services to their enterprise customers.

The Active Assurance product enhancements represent a key new element of Tektronix' market-leading Unified Assurance performance monitoring portfolio to provide network core-to-premise visibility into VoIP, data and Fax-over-IP service delivery at the network, service and customer layers for a complete end-to-end performance monitoring solution. These enhancements enable service providers to recognize and address problems that may arise at the premise, providing better understanding of their enterprise service customers' quality of experience.

"As VoIP service adoption begins to span large-scale deployments in the enterprise, providers need to ensure VoIP reliability and quality exceed service level agreements and customer expectations," said Doug Dickerson, Vice President and General Manager, Network Management, Tektronix. "Tektronix' active test solutions provide the carrier visibility into the enterprise in order to rapidly identify, isolate and resolve service issues. This enables our service provider and cable customers to provide their enterprise end users the best possible VoIP service quality."

Tektronix' New Enterprise-Specific VoIP Monitoring Solutions

The new high-performance test probes extend Tektronix' comprehensive service and network monitoring from core, edge and access networks to directly within customer premises. Unique to the industry, Tektronix complements this extended reach into the enterprise by adding wideband or high-definition VoIP codec support to active speech quality tests. With the new capability, providers can perform Fax-over-IP testing over narrow and wideband codecs from an enterprise site to other sites both on-net and off-net.

  -- The PowerProbe® 100 active test probe, designed for large enterprise
     on-site installation, generates and responds to active test calls on
     any standard VoIP interface, including analog connections in hybrid
     VoIP/Legacy PBX installations. Because probes can receive test calls at
     an assigned phone number, tests can traverse firewalls and session
     border controllers to validate VoIP service quality as experienced by
     actual callers, while ensuring the security and encryption valued by
     enterprise IT organizations are not compromised.

  -- Tests controlled by the web-based Tektronix DirectQuality® R7 test
     automation OSS enable complete VoIP service validation: speech quality
     tests provide PESQ MOS, and R-Factor over both standard and wideband
     VoIP (G.722) standards, in addition to a complete range of underlying
     analog and IP impairments such as echo, noise, voice-path delay, call
     volume and clipping. Tests can also verify and troubleshoot caller ID
     and voicemail issues, IP network performance as well as Fax / FoIP
     connection and transmission performance.

  -- The PowerProbe 50TG active test responder with active media-stream test
     generation provides comprehensive VoIP and IP quality of service
     validation for small enterprise sites. The PowerProbe 50TG can respond
     to calls from other 50TGs as well as PowerProbe 100's for site-to-site
     automated mesh-style service testing and on-demand troubleshooting to
     identify site-specific issues.
