Spirent(R) Communications Partners With SL Corporation(R) to Enhance Reporting in Perform(TM) OSS

Customers Benefit From SL RTVIEW's Extensible and Customizable
Real-Time Visibility
CORTE MADERA, Calif.--(Business Wire)--
SL Corporation(R), a leading provider of real-time monitoring,
analytics, and visualization software, today announced that Spirent
Communications plc (LSE:SPT), a global provider of performance
analysis and service management solutions, selected SL's RTView(TM) to
enhance the reporting functionality within the Spirent Perform(TM)
operations support system (OSS). The integrated solution helps Spirent
provide customers with a fully supported and extensible visualization
solution that meets their current and future management needs.

"RTView's robust and extensive feature set helps ensure our
Perform clients have the ability to deliver the most effective
dashboards, alerts and reports for their businesses, now and going
forward," said John Cunningham, vice president, Service Assurance at
Spirent Communications.

Spirent Perform is an advanced OSS that provides automated quality
of service (QoS) monitoring and assurance to help companies such as
Qwest, Embarq, and Sprint/Nextel manage Service Level Agreements. The
latest release of Perform, version 2.0, fully incorporates the RTView
platform, and all existing reports have been migrated to RTView.

Spirent upgraded the standard reporting functionality within
Perform to a more comprehensive and customizable visualization
offering. They chose to work with SL Corporation because of RTView's
reputation and capabilities beyond standard reporting, including:

-- DBMS support for retrieving data from sources such as XML
streams, Web Services, HTM/Scrape, JMS

-- Real-time GUI views

-- Animation capabilities

-- Support for queries from various sources into one table

-- Data collection/storage - can collect data from various
databases and store them within a single or multiple other
data sources

-- Alerts available such as SNMP traps and customized
alerts/actions

-- Customization available for commands, functions, and external
interfaces

"Perform enables Spirent's customers to more tightly monitor their
networks and offer increasingly stricter SLAs, thereby increasing
revenues and margins," said Ted Wilson, vice president of Business
Development for SL Corporation. "The comprehensive real-time
visibility provided by RTView will further help these customers to
identify performance issues more quickly - prior to impacting services
- which can lead to significant operational cost savings."
