The Advisor IP Telephony Analyzer and the IP Telephony Reporter offer features that allow for more insightful voice-quality assessment, combined with diagnostics, for optimized network performance. The analyzer improves voice-quality testing by allowing analysis of the voice traffic on a packet network. The software allows network engineers to isolate the cause of poor voice quality within the VoIP network, while providing the option of hearing the audio with jitter A flicker or fluctuation in a transmission signal or display image. The term is used in several ways, but it always refers to some offset of time and space from the norm. For example, in a network transmission, jitter would be a bit arriving either ahead or behind a standard clock cycle or dejittered. In addition, the analyzer adds features that automate the troubleshooting of networks suffering from jitter and packet loss. The Reporter brings together the end-to-end measurements of delay, objective voice quality and echo gathered from Agilent's Voice Quality Tester (VQT VQT Voice Quality Tester VQT Virtual Quality Tester (Agilent) VQT Voice Quality Testing ), and data on problems inside the packet network gathered from the analyzer. It then presents this information in a single report that baselines voice-quality vs. packet-network metrics. The voice-quality measurements produced by the VQT are plotted on a 3D graphical display, providing an instant impression of overall voice quality as experienced by the listener. Other reports indicate how voice quality varies over time, whether unacceptable voice quality coincides with changes in packet network behavior and whether high voice utilization impacts data network application response times and throughputs.--Agilent www.agilent.com Circle 303 for more information Bandwidth manager Booth 350 MANAGE LEGACY AND PACKET SERVICES with one device.
