Veraz Enhances Softswitch for Transitioning IN to IP

Veraz Networks announced the latest release of its ControlSwitch Interconnect, designed to help service providers migrate Intelligent Network (IN) service platforms as well as PSTN transport and peering signaling to IP. Additionally, advanced Quality of Service (QoS) routing improves revenue assurance through the enforcement of network-wide agreements.

Major enhancements to the ControlSwitch-IC include:

  • New Directory Services Element: The element adds application layer capabilities, enabling the transition of IN-based services to IP which improves operational costs and flexibility of the services themselves. For example, large databases containing hundreds of millions of numbers such as screening databases for the National Do Not Call Registry and number mapping databases such as nationwide local number portability and telephone number mapping (ENUM) can be migrated over to IP.

  • Advanced QoS-based Routing Module: This module allows service providers to meet custom service level agreements (SLAs) by measuring network quality fluctuations and dynamically enforcing network-wide routing policies. It also improves revenue assurance by being able to charge a premium for meeting priority levels of service.

  • New Signaling Element: The element lowers the cost of signaling by enabling the efficient backhaul of PSTN signaling over IP via M3UA, an industry standard signaling transport protocol. The ControlSwitch-IC can now connect directly to standards compliant IP signaling gateways and IP based STPs thus enabling operators to avoid the cost of separate PSTN signaling backhaul networks. Additionally, to simplify the move to direct IP peering between service providers the ControlSwitch-IC now supports industry standard IP signaling that preserves important information from traditional PSTN SS7 signaling that for example, identifies how a video call travels across different carrier networks.

ControlSwtich-IC supports PSTN signaling backhaul over IP based on the Message Transfer Part 3 User Adaptation (M3UA) protocol, an industry standard. SIP-I is a supported industry standard which is used to support direct IP peering between carriers in a way that preserves traditional PSTN signaling.
