The CX-UA Series brings together a flexible transmission access node and optimization device. Housed in a compact 1U chassis, the CX-UA delivers 2G-3G CDMA/GSM traffic aggregation and bandwidth optimization at the cell site or RAN hubbing point. It also offers a variety of backhaul interfaces and transmission options, including high speed direct interfaces to the Base Station Controller (BSC) or Radio Network Controller (RNC) nodes.The CX-UA family is comprised of 3 products: CX-UA 1000, 4000 and 9000. All CX-UA platforms are designed to the most stringent carrier-grade standards, anf offer 1+1 or 1:n redundancy options. The CX-UA 1000 is the access node; it offers up to 32 E1 interfaces, Ethernet and STM-1 SDH interfaces (electrical or optical). . The E1 interfaces may be used to connect the NodeB, BTS or the RAN transmission equipment. The CX-UA supports Abis, CDMA TDM, CDMA ATM, Iub (with ATM-IMA), ATM-IMA uplink and Ethernet or IP/MPLS interfaces and protocols.
The CX-UA 4000 and 9000 (at the central office) both offer a high density modular chassis, connecting traffic to the RNC, or BSC over a choice of STM-1, STM-4 or GE interfaces.
