    Why are Service Providers deploying Veraz ControlSwitch?

    It Works!

    Architecture Compatibility with IMSCentralized Management

    Network components can be distributed globally but they can be managed as onefrom a single location with features such as end to end call tracing and single CDR

    Extensive Reporting and Troubleshooting Tools

    Geographic Redundancy and Distributed Architecture System components can be distributed geographically for scaling and high

    availability

    ControlSwitch runs on Off-the-Shelf Sun hardware providing investment protection

    Cost Effective Scalability

    Can start small and grow with incremental upgrades without any fork lift upgrades

    Multi-Protocol Connectivity Provides transparent connectivity between any TDM Nodes (ANSI/ETSI ISUP, PRI,

    CAS) and IP Nodes (H.323, SIP, MGCP, H.248)

    Most Flexible and Easy to Customize Routing

    Service Customization using Veraz Services Framework

    New customized Communication Services using XML based service creation tool togenerate New Revenue for Service Providers

    Carrier-Grade High Availability

    3 Levels of Redundancy/Reliability

    Device redundancy

    1:1, 1:N, Load-sharedNo single point of failure

    Network redundancy Use of reliable network layer protocol, SCTP

    Redundant IP interfaces for ControlSwitch message transport

    Quad redundant connections to MGs for Control and Backhaul

    Overload protection

    Protects system from congestion related failures
