Handheld Ethernet analyzer accelerates VoIP turn-up

Test equipment supplier Agilent Technologies Inc. announced a voice-over-IP (VoIP) test kit for its existing N2620A FrameScope Pro handheld Ethernet performance analyzer.

The N2620A FrameScope Pro uses a unique auto-test feature that measures the performance of network resources such as DHCP and DNS, as well as file, e-mail, and Web servers. The N2620A is billed by Agilent as the most compact Gigabit Ethernet troubleshooting and RFC-2544 network performance benchmarking tool in its class.

Gigabit line rate
Capable of generating traffic up to full gigabit line rate, and equipped with optical and electrical ports, the N2620A supports end-to-end Ethernet testing. It does that across the entire network infrastructure needed for the provisioning of voice-video-data so-called triple-play services.

The new VoIP testing capability can help you deploy voice services to Ethernet-based networks. Network qualification that goes beyond bandwidth measurement ensures a smoother transition to VoIP. The FrameScope Pro can provide the visibility of network conditions that directly affect voice quality.

Operator-independent QoE (quality of experience) measurements based on MOS (Mean Opinion Score) and R-factor as defined by the ITU-T G.107 specs make verification and documentation of service level agreements unambiguous. That results in fewer troubleshooting tickets and shorter time spent at sites.

Live or pre-recorded
The tester now lets you set up a full-duplex VoIP call between two points, and perform voice-quality tests using either live audio or pre-recorded speech. To facilitate VoIP service turn-up, the FrameScope Pro VoIP emulates a SIP (Session Initiation Protocol) phone at any network access point.

VoIP calls between two FrameScopes are also possible even without a VoIP service infrastructure in place, such as an SIP server as per RFC 3261.

The benefits of the FrameScope VoIP include a unique Autotest feature. It applies for both troubleshooting and network pre-qualification, delivering detailed test results with minimum configuration effort. You also get pre-defined performance test suites. They let operators run tests by pressing a single button.

Other benefits include remote control using any Web browser. That supports central troubleshooting, monitoring and reporting, eliminating costly personnel dispatches. You also get support for Point-to-Point Protocol over Ethernet (PPPoE). That accommodates dial-in configurations.

The N2620A FrameScope Pro now also supports active and passive Autodiscovery. The Autodiscovery feature can help to automatically identify network resources, as well as rogue stations.

The N2620A FrameScope Pro VoIP package is already available, with prices starting at $6,300.
