Memotec - Redefining Network Efficiency

2G-3G CDMA/GSM traffic Aggregation and Optimization

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 2 products: CX-UA 1000 and 9000. Each platform is designed to the most stringent carrier-grade standards, and offers 1+1 or 1:n redundancy options.

Access Node

The CX-UA 1000 offers up to 48 E1 interfaces, Ethernet and STM-1 SDH interfaces (electrical or optical). The E1 interfaces may be used to connect the NodeB, BTS or the mobile RAN transmission equipment.

*Supports Abis, CDMA TDM, CDMA ATM, Iub (with ATM-IMA), ATM-IMA uplink and Ethernet or IP/MPLS interfaces and protocols. 

At the Central Office

The CX-UA 9000 offers both a high density modular chassis, connecting traffic to the RNC, or BSC over a choice of STM-1 or GE interfaces.

A DCME Opportunity

Operators across developing countries have been astounded by the huge and rapid success of HSPA. Whether you have a Media Gateway or not, a DCME voice compression solution provides an advanced compression rate and offers an efficient evolution path to an all-IP network to support the rapidly growing demands HSPA places on network infrastructure.

A common challenge

Network departments are often forced to rapidly react to new 3G/HSPA service initiatives in order to avoid horrible bandwidth capacity bottlenecks. With typically less than a month lead time, Network departments are confronted with revamping networks using limited personnel, equipment and financial resources.

Quick and simple assessment

While at first glance it may seem a short-term tactical implementation, revamping voice traffic management and compression is a quick and simple improvement that offers immediate and long–term benefits. DCME compression is a sophisticated method of freeing-up high-quality bandwidth on the existing network to accommodate premium 3G traffic, avoiding customer churn and improving revenue potential.

A Plug and Play Solution

Memotec’s DCME solution offers a 16:1 compression rate with sustained quality. It’s a plug and play implementation that relieves bottleneck pain points instantly and seamlessly integrates within the existing IP network.
