IPTV & VoIP Service Tests

The roll out of IPTV & VoIP services are a key priority to Telcos as a means of increasing revenue by adding value to a broadband service that has become commoditized and extremely competitive due the Local Loop unbundling taking place in telephone exchanges worldwide.

These VoIP and IPTV Customers will be extremely sensitive to any loss or degradation of their home entertainment services and rapid diagnosis of problems is essential. Abortive costly visit deep into the local access network is time consuming and will jeopardize guaranteed SLA repair times. The VoIP and IPTV Service tests enables remote testing of the these services for real time repairs.

IPTV Service Test of the UTest 318 Testhead

The IPTV Test Option for the UTest 318 is ideal for the maintenance and testing of IPTV services. The IPTV Service Test option can also be used to gather performance statistics on operational lines using qualitative sampling techniques. The IPTV features in the service test module allows real time Zap tests to confirm channel availability / measure channel transition time and a gather comprehensive range of IPTV Quality of Service statistics on a regular or on demand basis.
