Triple-Play Service Deployment

Chapter 10: Service Assurance for Triple-Play Services
Service Assurance Challenges for Triple Play
Providers are making use of the functionality of existing network
element and service reporting and fault management systems.
Yet, these systems must be augmented in order to deliver the
required QoS for new triple-play services. While the required
additions vary, essentially at issue is the need to add video tools
to the legacy voice provider and voice tools to the legacy video
provider.
For providers new to the video market (IPTV service delivery),
systems must be implemented to:
– Ensure the quality of video services as launched from the
headend.
– Deliver video services error free across the optical network.
– Manage the performance of xDSL loop to optimize the
bandwidth and service offering.
– Monitor the service performance end to end including the loop
and home environments.
For providers new to the voice market (VoIP service over hybrid
fiber/coax), systems must be implemented to:
– Ensure quick identification and isolation between loop and
network and handoff service issues.
– Monitor the performance of the upstream ingress to ensure
loop quality is sufficient for VoIP.
– Ensure total voice customer experience including managing
delay, jitter, packet loss and echo.
By adding components to address these issues to an existing
service assurance portfolio, the provider can ensure the ability to
deliver the new service with high availability.
