DUA Software

DUA is a SIGTRAN protocol for transporting DPNSS/DASS Layer 2 user part signaling messages (i.e. DPNSS Layer 3) over IP using the Stream Control Transmission Protocol (SCTP).

DUA can be used between a signaling gateway and Media Gateway Controller, between a signaling gateway and IP signaling point and between two IP signaling points.

The DUA software is portable C source code that can be compiled to run on any processor, under any operating system, and with any system architecture. The modular design and simple interfaces allow the DUA software to be easily ported to any environment.

Trillium DUA software enables telecom equipment manufacturers of soft switches, signaling gateways, access gateways, signal transfer points, service control points, media gateway controllers or other products to:

  • Accelerate time to market
  • Reduce development costs
  • Reduce project risk of internally developed DUA applications

Product deliverables consist of C source software, documentation, training, a warranty and technical support.
