Press Release Summary: Accedian Networks Inc., a leading provider of Service
Assurance solutions and Ethernet Demarcation Devices, today announced the
introduction of a new technology allowing Ethernet Service Providers to validate the
maximum throughput of a circuit while the end-customer traffic remains completely
unaffected.

Press Release Body: Montreal, QC, October 11th 2007 - Light Reading's Ethernet Expo
2007, booth #329 (New York, NY) - Accedian Networks Inc., a leading provider of
Service Assurance solutions and Ethernet Demarcation Devices, today announced the
introduction of a new technology allowing Ethernet Service Providers to validate the
maximum throughput of a circuit while the end-customer traffic remains completely
unaffected.

The new patent-pending feature allows carriers to prove the end-user is getting the
bandwidth he's paying for without having to bring down the service, and thus
generating considerable savings in OPEX by avoiding the use of costly maintenance
windows (nights and weekends). Furthermore, it allows periodically exercising
maximum service performance after commissioning changes in the network.

"For the past several years, RFC-2544 has been the standard method to validate the
performance of an Ethernet Virtual Circuit at the time of turn-up or out-of-service"
said Patrick Ostiguy CEO of Accedian Networks "Accedian now offers a breakthrough
method to perform in-service RFC-2544 validation non-intrusively, while end-user
traffic continues flowing seamlessly".

Embodied within Accedian's Ethernet Demarcation Devices, this technology is the
first to add Throughput Measurement as part of End-to-end live Ethernet SLA
verification. Completely non-service affecting and based on the RFC-2544 standard,
this new feature utilises the end-customer traffic as part of the test pattern in
order to exercise End-to-end CIR/EIR/CBS/EBS parameters of an EVC while the end-user
applications continue flowing through in a seamless fashion.

Accedian's Seamless Throughput Measurement will be demonstrated at Light Reading's
Ethernet EXPO 2007, October 15-17, 2007, New York, NY, New York Hilton, booth #329.
