ACE-3402 - Aggregation-Site Gateway
ACE-3402 is a multiservice carrier-class gateway, designed for cost-effective backhauling of 2G/3G voice and HSDPA data traffic over multi-generation access networks, such as Ethernet and SDH/SONET. ACE-3402 uses advanced pseudowire (PW) technology to deliver cellular and legacy traffic services (ATM, TDM) over next-generation PSNs (packet-switched networks), including Layer-2, MPLS, and IP. Typically located at the RNC/BSC site, the unit converts and aggregates traffic using channelized STM-1/OC-3, ATM STM-1/OC-3c, and Gigabit Ethernet interfaces.
The SDH/SONET and Gigabit Ethernet interfaces operate as a user or network ports, per-user configuration and depending on the required application. In addition, ATM or TDM traffic received via the channelized STM-1/OC-3 ports is converted by ACE-3402 to either ATM (UNI or IMA), CES or SAT over PSNs, depending on the originating traffic type.
2G/3G over ATM, SDH/SONET, PSN
Typically located at hub sites or BSC/RNC sites, this device ensures the most economical allocation of backhaul resources in delivering 2G, 3G and next-generation services over ATM and SDH/SONET transport networks. Moreover, the ACE-3402 incorporates advanced pseudowire emulation capabilities, supporting operators in their migration to cost-effective packet transport by enabling the use of wholesale DSL services and Ethernet, IP or MPLS backbones for the provisioning of delay-tolerant, as well as real-time services. The ACE-3402 is a 2U-high device and fits into 19-inch racks for easy installation in limited spaces.
