Q.933 / LMI Software

The Frame Relay Control Protocol portable software product provides the status signaling for PVCs (LMI) and/or signaling to establish, maintain and release SVCs (Q.933 / X36 / FRF4 / X76 / FRF10).

The software supports the User-Network Interface (UNI) and/or Network-Network Interface (NNI). The Frame Relay Control Protocol software product supports the ITU-T, ANSI and Frame Relay Forum variants of the protocol. The software has the following components:

  • Signaling Protocol. It supports UNI signaling – Q.933 Case A, Q.933 Case B, FRF4, X36 and NNI signaling – X76 and FRF10. The signaling protocol also provides capabilities to establish, maintain and terminate Switched Virtual Connections (SVCs) and to detect and recover from errors. The SVCs are established by exchanging signaling messages with a frame handler within the network over any Bearer channel (B-channel).
  • Local Management Interface (LMI) protocol. It provides capabilities to manage and maintain Permanent Virtual Connections (PVCs), verify link integrity and detect and recover from errors.

Trillium Q.933 / LMI software enables telecom equipment manufacturers of soft switches, signaling 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 Q.933 / LMI applications

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