VoIP deployment over Fast and Gigabit Ethernet, in enterprise and carrier networks, brings new challenges to network support organisations. These include assessing live speech quality and troubleshooting poor call connections. JDSU's DA-3400 VoIP Analysis Software provides fast assessment of live VoIP calls plus real-time expert analysis of control signalling. Gain fast insight into all aspects of VoIP service and infrastructure while analyzing live service.

Challenges

• Determine relative speech quality across IP networks
• Measuring IP call quality against traditional analogue perceptual quality standards
• Determining quickly the call delay, the codec, packet loss and network jitter
• Determining where in the network errors are affecting call quality
• Troubleshooting signalling problems

The VoIP Analysis Software Solution

The DA-3400 VoIP Analysis software provides visibility into all VoIP calls on the network link. On connection, the VoIP Analysis Software automatically detects all active calls and rates them using the ETSI TIPHON standard. Call control signalling is analyzed with the Acterna “Mentor” Expert system producing signalling statistics, error events and on-line protocol decode to speed up troubleshooting. Easy to use statistics detail individual call parameters plus a graphical representation shows the terminal end points and the problem network section is highlighted.

• Call detection and cumulative aggregate call quality
