Accedian Selected by FiberTower for Service Assurance of Ethernet-Based Backhaul

Montreal, Canada, November 07, 2007 --( Accedian Networks Inc., a leading provider of Service Assurance solutions and Ethernet Demarcation Devices, today announced that FiberTower Corporation (NASDAQ: FTWR) has selected and deployed the Company’s EtherNID™ SLA-Meter™ platform to measure performance and assure Service Level Agreements (SLAs) on its Ethernet-based backhaul network. FiberTower, a leading alternative provider of backhaul services for wireless carriers, chose Accedian’s Ethernet Service Assurance Platform to monitor SLA parameters end-to-end in a multi-point environment.

The Accedian EtherNID™ family allows backhaul service providers to guarantee stringent Ethernet SLA parameters between each Base Station and the Mobile Switching Centers, a key requirement in the intensive rollout of 3G and WiMAX service initiatives currently taking place in the US.

“Accedian’s platform allows us to take control of our SLAs and to map out the health of our network in real-time, enabling us to deliver on the stringent 3G and 4G backhaul requirements set down by our carrier customers,” said Michael Finlayson, FiberTower’s Senior Vice-President of Technology.

The Accedian EtherNID™ platform incorporates a highly accurate hardware-assisted engine (PAA™), which allows constant and seamless in-service monitoring of SLA parameters including packet loss, latency (delay), jitter (delay variation) and continuous end-to-end path continuity check (availability). All of this is achieved across (up to) 100 simultaneous customer traffic streams, with an ultra-precise one microsecond resolution in an end-to-end, multi-point fashion.

“Because of the very stringent, few millisecond-level, SLA parameters asked upon wireless backhaul providers, SLA measurements must be performed in the micro-second domain” said Patrick Ostiguy, President and CEO of Accedian Networks Inc. “With its highly-scalable multi-point topology support and its ultra-high density form factor, the EtherNID™ family is optimized for wireless backhaul projects.”

Additionally, the EtherNID™ features a high-performance Fast-Thru™ engine and thus minimizes intrinsic packet-jitter and latency of the device, as well as sub-microsecond at 100% wire-speed for all packet sizes, including jumbo packets up to 10,240 bytes, virtually eliminating the introduction of latency or jitter to the service itself.
