ACE-2002    Multiservice Access Concentrators and ATM NTUs

Multiservice Access Concentrator and ATM NTU

RAD’s ACE-2002 multiservice access concentrator and ATM NTU is a carrier-owned demarcation device designed to deliver Ethernet and voice services over ATM, to improve network efficiency and to ensure end-to-end QoS. Aggregating up to six STM-1 links to STM-1/STM-4 or 16 E1/T1 links to an STM-1/OC-3 trunk, the ACE-2002 is particularly well suited for cellular backhaul applications, providing a cost-effective method for aggregating traffic from 2G/2.5 G and 3G stations. In other applications, it is used as a multiservice concentrator, handling diverse corporate traffic in medium to large enterprises.
