Atrica achieves sub-50 millisecond protection for Metro Ethernet Networks

Fiber Optics Weekly Update, June 7, 2002

Atrica announced that independent testing lab, The Tolly Group, has completed a series of rigorous tests with Atrica's Optical Ethernet System and has confirmed its ability to successfully recover from failures in less than 50-milliseconds - a capability previously achievable only in SONET networks.

The tests also verified that Atrica's Optical Ethernet System can ensure carrier-class Service Level Agreements (SLAs) during heavy traffic load periods and can deliver toll-quality voice over Optical Ethernet, conforming to the requisite latency, measuring jitter on a T1 line, and PESQ (Perceptual Evaluation of Speech Quality) standards. The Tolly Group tests demonstrate that Atrica's A-2100 Optical Ethernet Edge Switch and A-8000 Series Optical Ethernet Metro Core Switches adhere to the key The Tolly Group designed a test bed consisting of the devices under test -- two Atrica A-2100 switches and two Atrica A-8000 Series switches, two CSU/DSUs connected via a T-1 link, a Spirent SmartBits SMB-2000 for data traffi c generation, an Acterna Domino Fast Ethernet internetwork analyzer and an Agilent Voice Quality Tester.
