Test and Measurement challenges for NGN Networks: Get Livingston view
Test and Measurement challenges for NGN Networks: Livingston provide you some thoughts .Converged & Triple Play Networks - what’s involved in making them work - from the core to the edge –
The success of Converged and Triple Play Network projects will rely on effective pre and post-deployment testing of technologies, network equipment, and operational networks. These new networks present different challenges and this short presentation looks at different methodologies and techniques for stress testing of core, metro edge and MSAN devices, networks and services – from development to deployment.
The impact of Triple Play Services on Field Workforces -As the deployment of traditional and FTTN-fed ADSL2/2+ and VDSL/VDSL2 services continues to take off, it becomes increasingly important to focus on an efficient means to install and maintain the service. Maintaining high data rates is especially crucial to the delivery of voice, video, and data to each subscriber. Providing field technicians with test sets with expert diagnostics, along with an automated process, not only decreases the time to resolution by enabling the dispatch of a single technician, but it also allows the technician to quickly learn how to test new services. In addition, this type of disciplined approach provides a method of trending to predict future problems, lowering mean time to repair and repeat rates.
Splice loss specifications and how each parameter can impact on the quality of your splice. Issues such as core/cladding concentricity error, mode field diameter tolerance, outside diameter tolerance and fiber curl tolerance, outside diameter tolerance and fiber cur can impact on splicing legacy and new fibres.
Speech Quality Assessment ; What about measuring voice quality and outline the advantages of objective testing over traditional subjective methods. With the convergence of today's networks, repeatable voice quality tests over IP networks are essential to ensure acceptable service delivery.
Why Test Triple Play Services ? Performance parameters affect the service quality experienced by the subscriber, so should the objective be to offer QoS to support data, voice and video services, or, would over provisioning be better than accurate QoS control over the network?
Testing of Triple Play Applications across Next Generation Networks Triple Play is the biggest evolution in the Telecommunication since DSL. IPTV and VoIP are the leading applications and services providers hope to increase their ARPU (Average Revenue Per User) while using their old copper lines. For the Triple Play players, it is a new and difficult challenge to deploy and maintain such new services, involving new technologies like ADSL2+, VDSL2, FTTx, VoIP, IP Video, etc…Take a look at "what can go wrong?" and how portable test equipment can solve the following problems : - VoIP analysis : call generation, call capture, detailed signalling monitoring, MOS score and playback of the call, - IPTV testing from the end user: live measurement of the VMOS and each parameters of the Video over IP.
Critical Testing Parameters for 21st Century Optical Networks - As data rates increase from 2.5Gbits/s to 10Gbits/s, the effects from parameters such as Chromatic Dispersion & Polarisation Mode Dispersion can become the key limits on the performance of an optical fibre link. As such it vital to understand and to be able to measure the levels of these parameters to ensure an optical fibre link is not unnecessarily impacted.
IPTV Test & Monitoring in Triple Play Networks
Video is unique – it is not just like any other content type. It requires guaranteed available bandwidth in a best effort network, it's intolerant to network jitter and lost packets, and it's intolerant to resends and out of sequence packets. The user experience is critical, and poor quality video/audio is highly noticeable. Network Test, Video Test, and Network Monitoring are part of the solutions to deliver quality in IPTV
Behind those inputs we do have products to support the requirements.
