Avaya is expert in delivering industry-leading IP telephony solutions and integrating them into existing networks. But when the company decided to deploy its IP solutions across the Avaya enterprise - they faced the same challenge that the customers face: How to know if the network is ready to support IP telephony? Network readiness is crucial to effective IP telephony deployment, to achieve real-time voice quality and take advantage of all the cost savings and application benefits of IP-enabled solutions. That's why Avaya Global Services and Avaya Labs joined forces to create a comprehensive tool to assess the readiness of an enterprise's network before deployment of an IP telephony solution: the Avaya ExpertNet VoIP Assessment Tool. tech news

A radio network is described for configuring, monitoring, and diagnosing the components of a computer system. Such a network offers several advantages. It improves the robustness of the overall system by not having the monitoring functions rely on the interconnect of the monitored system. By broadcasting information, it offers direct communication between the monitoring and monitored components thereby removing dependencies inherent to hierarchical and daisy-chained wired networks. It does not rely on a physical interconnect thereby lowering implementation cost, offering non intrusive monitoring, and improving reliability thanks to the lack of error- and failure prone cables and connectors. tech news

Many of today's signal level meters, spectrum analyzers, and quadrature amplitude modulation (QAM) analyzers support the measurement of both analog TV channels and 64- and 256-QAM digitally modulated carriers. TV channel signal level or amplitude generally refers to the channel's visual carrier amplitude, which is defined as the root mean square (rms) value of the instantaneous synchronizing peak. Digitally modulated carrier amplitude is a measure of the signal's average power. This paper summarizes the step-by-step procedures pertaining to the measurement of analog TV channel and downstream digitally modulated carrier amplitudes using Agilent's (formerly Hewlett Packard's) 8591C spectrum analyzer. tech news

Cable operators routinely measure carrier-to-noise ratio (CNR) as one means of characterizing the health of their cable networks. Government regulations require that cable networks meet certain minimum standards for analog television signal CNR. Also, the DOCSIS Radio Frequency Interface Specification includes in its assumed RF channel transmission characteristics a minimum CNR parameter for data signals. But just what is CNR? This white paper provides a comprehensive tutorial on the subject. tech news
