Triple-Play Service Deployment

Troubleshooting High Speed Data Service
Traditional telecom providers face enormous challenge, but also
great opportunity, in addressing today’s market for the high
speed data service component of triple play. As carriers adopt
FTTx strategies that can make triple play a reality, a considerable
hurdle remains: optimizing the use of existing copper facilities to
meet performance and QoS expectations. This must be
accomplished in a competitive environment which is already
seeing some providers lose market share.
Over the last few years, with the advent of VoIP and IPTV, high
speed data service has gone from the most to the least critical
service from a performance standpoint. Yet it still requires fast
and effective turn-up and troubleshooting in order to retain
customers and keep costs at a level conducive to profitable
service delivery. Despite the fact that VoIP and IPTV applications
inherently require higher network performance, high speed data
service delivery is more closely scrutinized because users tend to
be the most technically savvy and demanding members of the
customer base. Providers have found that data service, too, must
perform as advertised, to retain customers. Furthermore, with
advanced networked video peer-to-peer sharing technology
beginning to emerge, the demand for increased up-stream
bandwidth is a new and challenging paradigm shift.
