Global Title Translation

Intelligent networks and wireless switching systems often do not perform Global Title Translation (GTT) efficiently. When services such as enhanced 800/900, virtual private networks and HLRs are triggered, the switches suspend call processing and launch a query into the network toward the adjacent STP. The message contains address information that determines the GTT to be performed. When services are distributed across multiple service control points or HLRs, GTT provides efficient routing and redundancy. Keeping the GTT information in

a central pair of STPs supports efficient and flexible operation of the network. The Alcatel 5070 SSG ANSI provides the powerful, real-time processing necessary to meet these GTT requirements.

Gateway Screening

The Alcatel 5070 SSG ANSI acts as a gateway for messages transferred between networks.

Increasing competition and globalization

of the telecommunications market prompted requirements for monitoring, measuring and controlling access between SS7 networks.

Consequently, the Alcatel 5070 SSG ANSI Gateway Screening feature has become increasingly important to ensure network security.

The Gateway Screening feature allows for message traffic based on commercial agreements. This feature provides operators with the ability to protect against unauthorized traffic between networks, to protect against malicious and unauthorized access to the network, and to collect measurements on traffic screening results. The Alcatel 5070 SSG ANSI provides the ability to screen messages as they are received.

Gateway Screening prevents unauthorized access to databases and prevents use of unleased facilities and services. In the screening process, the MTP and SCCP parts of the message are
