Service providers are enhancing their networks to offer real-time interactive applications with the highest Quality of Service that ensures customer satisfaction and retention. Increasingly, it is being realized that timing plays a key role in the delivery of these services. These timing needs are driven by the requirement of the service rather than the transport equipment, which primarily utilizes synchronization. Synchronization has played a key role in ensuring QoS for the transport infrastructure. Service coordination and delivery of these new services such as IPTV, VoIP, online gaming, video conferencing and their service components such as ad insertion or billing also requires accurate timing throughout the network.

The TechThink Webinar presentations will include:

* QoS aspects of specific services that are impacted by timing

* Service quality as a competitive advantage

* Why time is money - the link between timing, next-generation applications and customer satisfaction and revenue assurance
