Summary Datasheet • AT-108 • 2Q 2016
Designed to meet requirements of carrier-grade Ethernet services, AT-108 is an eight port (1Gb/s), highly resilient network interface device that delivers unparalleled timing/synchronization accuracy, and low-cost, easy operation.
AT-108 is a compact Carrier Ethernet 2.0 service demarcation device well-suited for both business Ethernet and mobile backhaul solutions. Fanless, temperature-hardened construction makes these Elements very durable and suitable for the most demanding environments, including high-salinity coastal and industrial installations.
These Performance Elements support a variety of common resiliency methods and support all major synchronization standards. Cost-effective and easy-to-deploy, AT-108 units are an excellent choice for all Carrier Ethernet applications.
Key Applications Business services and data center connectivity strategies are supported with the Accedian AT series, with integrated, standards-based Ethernet OAM and SLA performance monitoring. MEF Carrier Ethernet functionality combined with granular Layer 2 and 3 traffic conditioning allow this low-cost element to support price-sensitive commercial offerings without compromise.
The wide range of integrated synchronization standards—powered by dedicated hardware—allows the AT to meet the demanding timing requirements of LTE and LTE-Advanced (LTE-A) backhaul networks while seamlessly supporting OAM, aggregation and other critical access networking requirements.
The Ethernet OAM feature suite built into AT series units provides thorough link, service, network monitoring, and performance metrics. Embedded hardware-based testing methods enable remote diagnostics and testing, effectively reducing truck-roll costs while assuring best possible quality of experience (QoE) to the end customer.
