Cello—An ATM transport and control platform
Ericsson’s WCDMA products for third-generation cellular systems are based on Cello, a telecom platform that can be used for several different products. Cello’s robust, real-time control system and efficient ATM transport system guarantee cost-effective applications for support with circuit-switched and packet-switched services alike.
WCDMA evaluation system—Evaluating the radio access technology of third-generation systems
Ericsson began testing WCDMA during the early part of 1995. Today, Ericsson operates fully developed WCDMA radio networks in several parts of the world. Ericsson’s WCDMA evalutation system facilitates UMTS/IMT-2000 standardization, by allowing operators and engineers to demonstrate and test third-generation services and solutions. It also enables them to learn about and evaluate WCDMA characteristics in ATM environments.
Tigris—A gateway between circuit-switched and IP networks
Tigris provides a gateway between circuit-switched and IP networks. Its flexible architecture allows traditional circuit-switched calls to enter or exit the world of IP. Its backplane provides for two bus architectures: TDM and high-speed Compact PCI. Combined with AccessOS software, this hybrid architecture creates a carrier-class multi-service and multi-delivery platform.
GPRS—General packet radio services
GPRS—the packet-data standard for GSM and TDMA/136 systems—enables operators to offer efficient mobile access to external packet-switched networks at transfer rates up to 115 kbit/s. Ericsson’s implementation of GPRS enables rapid deployment while keeping entry costs low.
Jambala Mobility Gateway—Convergence and inter-system roaming
Ericsson’s Jambala Mobility Gateway—which does not impose any modifications on individual network components—extends the boundaries of domestic and international roaming by allowing inter-system roaming.
Professional Services—Meeting the changing needs of network operators
Ericsson’s newly formed Professional Services business unit works in partnership with operators to bring new services to market in the shortest possible time. The Professional Services unit combines expertise and resources in the areas of consultancy, telecom systems integration and network management.
