CX-U Series |
Memotec’s CX-U Series is a dedicated cellular backhaul platform delivering Radio Access Network (RAN) optimization, and A/E voice trunks compression. The CX-U reduces the bandwidth required to backhaul cellular traffic, therefore avoiding costly forklift network upgrades. The result is a significant reduction in operating and capital expenses.

A core component of Memotec’s comprehensive cellular backhaul optimization solution, the CX-U Series is a powerful, robust T1/E1 access concentration and bandwidth compression platform intended for cellular applications. It uniquely combines 2G-3G traffic aggregation, RAN optimization and DCME voice compression features together into a single, compact, cost effective and versatile unit.
The CX-U supports a combination of any GSM 2G/2.5G (Abis, Ater, A/E, Gb/Gn), 3G (UMTS/W-CDMA) and PSTN voice trunk interfaces. It operates equally well with CDMA, TDMA and AMPS networks. Its unique embedded bandwidth management features enable superior bandwidth efficiency without sacrificing voice quality.
The CX-U can also be used as RAN gateway device for migrating the Mobile Operator’s access network to an all-IP-RAN.
The CX-U supports 2G-3G Abis & Iub aggregation and optimization, Ater link optimization, DCME digital voice trunks compression, non-blocking DS0 channels cross-connect and grooming, IP-RAN migration, ATM and TDM circuit Pseudowire, and HSPA offload.
The CX-U can be managed through Memotec’s tools:
- The CXTOOL provides a centralized, user friendly, graphical interface network element configuration function, as well as basic software and configuration management.
- CXMON which provides a dedicated sophisticated RAN interface (Abis, Ater, Iub, A/E links and WAN uplinks) real-time and statistic –24 hours- performance and alarm monitoring functions to the operator. In particular, CXMON is instrumental in helping the operator troubleshoot, monitor and fine tune the performances of its RAN transmission network.
- AGORA-NG which provides a complete full scope (FCAPS) carrier grade network management system, able to manage very large networks and the complete Operator transmission infrastructure (including the underlying PDH-SDH layer).
