In
addition, services can be changed from circuit to data on the same device and often
on the same port. This reduces the time it takes to deliver a new customer service
while it increases the probability of competing successfully for new customers.
?– Only one network is required whatever the mix of services. Historically, there have
been 2 networks required to support both data and voice services. As the proportion
of these two services changes, planning for upgrade and support of the services
requires educated guesswork about when and where equipment will be needed.
The new network supports both services interchangeably, there is never an imbalance
between customer demand and carrier infrastructure.
?– Customers can migrate from TDM to Ethernet with no change to the network. WilTel
expects the mix of services between TDM and Ethernet to fluctuate over time, with
Ethernet increasing and TDM decreasing. Because both services are efficiently
supported on the same platform, customers can change their service mix over time
without a negative impact on the CO equipment requirements.
?– Statistical multiplexing gains enable higher revenues.
