RTU Architecture

RTU is based on three functional subsystems.

Traffic Switch is a highly scalable universal engine which processes SIP, H.323, and ETSI ISUP (SIGTRAN)/MGCP* calls and performs two-way conversion of signaling protocols and voice codecs when necessary. Traffic Switch is managed by two types of logic subsystems: Basic Call Logic and VAS Logic.

Basic Call Logic is responsible for basic calls and call processing functions. It integrates a call management module, a database and web-GUI server.

VAS Logic is responsible for all types of advanced services based on RTU, such as IVR, conferencing, fax-to-email etc.

*national dialects are implemented on demand

Each subsystem consists of a number of separate functional modules, which makes the system as a whole easily scalable and redundant. The system operates on the industry-standard hardware.

Key advantages of distributed architecture:

• Excellent scalability
• High fault-tolerance
• Building geographically distributed networks with a single point management and data entry
• In case of a hardware fault in one of the system’s components, its functions are taken over by other servers in the cluster assuring business-critical system’s dependability.
