Triple-Play Service Deployment

258
Measurable Benefits
Successful triple play deployment requires managing multiple
services which place increasing bandwidth demands on the
network with differing traffic patterns. Any service provider
offering triple play cannot risk customer dissatisfaction and
resulting churn. Developing an effective service assurance
strategy that enables continuous monitoring and rapid reaction to
QoS issues will be a key service differentiator.
By implementing a service and network monitoring solution,analysis
has shown that a 15% reduction in truck rolls and 20% reduction in
MTTR can be achieved by proactively monitoring QoS and accurately
isolating the problem prior to dispatch.This 15% reduction translates
into significant cost benefits.The following example quantifies these
benefits for VoIP service based on the following assumptions:
VoIP Cost Savings Scenario
15,000 VoIP Subscribers
1 truck roll for every 10 VoIP subscribers per month
1 trouble ticket registered for every 7 VoIP customers per month
MTTR = 7 days x average time spent per trouble ticket per day (30 minutes) = 3.5 hours
$75 per truck roll
235 x 7 productive hours/12 months = 137 hours per month
$36 per hour network operations center tech (assumption of $60,000 salary divided by annual productive hours)
Cost/month
1,500 truck rolls (15,000 subscribers/10) x $75 per truck roll = $112, 500
2,143 trouble tickets per month x 3.5 hours per trouble ticket x $36 per hour NOC tech rate = $270,000.
Conservative Cost Benefit /Month
15% reduction in truck rolls translates to $16,875 savings per month
20% reduction in MTTR translates to $54,000 savings per month

Service providers can add to these savings the economic benefits
of increased customer satisfaction and reduced customer churn.
