The migration from traditional TDM access to Ethernet-based business and
wireless backhaul networks makes the provisioning and maintenance of
wholesale, business, and residential consumer services increasingly more
complex. Spirent's Ethernet customers are under pressure to meet and exceed
the stringent quality of service demands, particularly from their enterprise
users while keeping operating expenses in check as Ethernet services, network
architectures, and service and delivery configurations proliferate. In
addition, consumers' expectations are forcing service providers to offer high
performance data and video services that meet QoS and QoE levels expected
from subscribers.

"The ability to ensure network quality prior to service activation is a
huge advantage," said John Cunningham, president, Service Assurance Broadband
group at Spirent Communications. "Spirent remains the only company delivering
an Ethernet testing solution that allows carriers to rapidly launch new
services as well as decisively troubleshoot potential issues once a network
is live and operating."

Spirent is an established leader in Ethernet systems and services testing
within the service provider and network equipment vendor lab environment. By
leveraging the Ethernet testing expertise from the lab into the field,
Spirent ensures that customers are able to better diagnose and troubleshoot
the complex technology issues related to delivering Ethernet services over
converged networks. This effort then allows service providers to focus on
expanding their competitive footprint. This approach coupled with Spirent's
commitment to introducing advanced Ethernet solutions makes it the testing
partner of choice for the three carrier customers.

All three carriers implemented Spirent's market leading, SmartSight and
QoE Scope solutions to streamline service deployments and achieve critical
business objectives. Spirent's solution is uniquely positioned to address
carrier class business service offerings with a proven test platform
producing a competitive advantage. It allows service providers to outperform
their competition utilizing fewer resources per Ethernet line in service. The
improved service response capability reduces "customer churn" in this
volatile marketplace, maintains up sell potential to higher speeds and more
exotic services, and improves existing revenue retention while increasing new
revenue potential. For more information visit www.spirent.com/go/smartsight
