RAD Introduces Carrier Ethernet Demarc Device

RAD Data Communications introduced a Carrier Ethernet demarcation device that delivers SLA-based Layer 2 and Layer 3 business services to the customer premises over native Ethernet access. It provides delineation between the user network and the transport network for those services, as well as for mobile backhaul.


RAD's ETX-204A transports up to one gigabit of user throughput with differentiated quality of service and end-to-end monitoring to ensure SDH/SONET-like performance and 99.999 percent reliability. The device smoothly handles multi-priority traffic while ensuring latency, jitter, and packet delivery performance on a per-flow basis.


RAD also features a "SyncToP" timing over packet (ToP) that delivers clock recovery and distribution using IEEE 1588v2 (1588-2005) Precision Timing Protocol, Synchronous Ethernet (Sync-E) and a built-in input/output clock interface. It also provides unique flexibility in supporting the simultaneous use of different clock transfer methodologies, such as employing 1588v2 to receive the clock from the network and distributing it to the cell-site with Sync-E.
