Accedian Networks Announces Interoperability with Sunrise Telecom's(R) Leading Edge Ethernet Products.

MONTREAL -- Accedian Networks Inc., a leading provider of Ethernet demarcation devices and OAM solutions, announced today the interoperability of its EtherNID(TM) product family with Sunrise Telecom's STT(R) and Sunset MTT(R) Ethernet test sets.

Field Professionals can now initiate far-end Ethernet loopbacks across entire Layer 2 or Layer 3 carrier networks directly from the keypad of their STT or Sunset MTT, thus avoiding truck rolls and allowing single-ended testing of entire Ethernet service paths.

"By automatically reacting to Sunrise Telecom's STT and Sunset MTT in-band loop-up/loop-down commands, the Accedian EtherNID(TM) allows cutting by half the OPEX and CAPEX associated with the turn-up and troubleshooting of Ethernet Services." said Patrick Ostiguy, president & CEO of Accedian Networks. "This added interoperability will accelerate the turn-up of new revenue-generating Ethernet services and will increase end-customer satisfaction by optimizing the response time of carrier's field services teams."

By supporting the in-band loopback commands of industry-popular Ethernet Field Services test equipment, the Accedian EtherNID(TM) addresses an important pain-point that service providers have been expressing with regards to the Operations Administration and Maintenance (OAM) aspects of their Ethernet service offerings.

Accedian's EtherNID(TM) in-band loopback interoperability feature will be demonstrated at Globalcomm 2006, June 5-7th, McCormick Place, Chicago, booth #81078.
