The SCCP User Adaptation Layer (SUA) software product, defined by the SIGTRAN working group of the Internet Engineering Task Force (IETF), transports signaling messages from the SCCP users (that is, TCAP and RANAP) over the IP network.

Trillium SUA 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 SUA applications

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

FEATURES + BENEFITS

The SUA software provides the following features and benefits:

  • A management interface for configuration and control operations and status and statistics retrieval. It also provides protocol state and alarm information at the management interface.
  • Extensive run-time error checking support.
  • Extensive debugging support to ease system integration and testing.
  • Support for function call traces and tracing of incoming and outgoing PDUs. Trace information is provided at the management interface and can be used to support the remote logging and analysis operation.
  • Conforms to Trillium Advanced Portability Architecture (TAPA)
  • Benefits of licensing Trillium software from Continuous Computing

The SUA software provides the following features at an SGP:

  • Transfers all the SCCP user part (TCAP, RANAP etc.) messages received from SCCP (via IWF) to the ASs, consisting of redundant or load-sharing ASPs.
  • Manages the SCTP associations and the traffic between one or more SGPs and one or more ASPs or IP-resident databases.
  • TCAP traffic routing to the ASs, based on the GT/DPC/OPC/SSN parameters. All of these parameters, or a subset of them, are allowed for routing.
  • An ASP or IP-resident database failover and loadsharing. Multiple load-sharing algorithms (such as connection based) are allowed.
  • Interworking with SCCP for seamless SS7 and IP network management.
  • Dynamic registration of routing keys at the SGP.
  • Support for Global Title Translation

The SUA software provides the following features at an ASP:

  • The equivalent set of primitives to its upper layers (TCAP, RANAP etc.), as provided by the SCCP to its local users.
  • Routing Label information (GT/OPC/DPC/SSN) at the ASP, as expected by the SCCP user protocol layer.
  • Management of the SCTP associations and the traffic between the ASP and SG.
  • Enables SGP loadsharing. Multiple load-sharing approaches are allowed.
  • Transfers the SCCP user part (TCAP, RANAP etc.) messages to the peer ASPs.
  • Supports the dynamic registration of the routing keys at the ASP.
  • Support for Global Title Translation

The SUA software provides the following features at an IPSP:

  • Both single-ended and double-ended behavior (as specified in RFC 3868) of the IPSP through the configuration parameter, per remote node basis.
  • The equivalent set of primitives to its upper layers (TCAP, RANAP etc.), as provided by SCCP to its local users.
  • Manages the SCTP associations and the traffic between IPSPs.
  • Transfers the SCCP user part (TCAP, RANAP etc.) messages to the peer IPSPs.
  • Supports the dynamic registration of routing keys at the IPSP.
  • RANAP traffic routing to the ASs based on the DPC/OPC/SSN/GT range parameters. All of these parameters, or a subset of them, are allowed for routing.
  • TCAP traffic routing to the ASs based on the DPC/OPC/ SSN/GT parameters. All of these parameters, or a subset of them, are allowed for routing.

PRODUCT INTERWORKING

Trillium SUA software interworks with the following Trillium products:

  • Stream Control Transmission Protocol (SCTP)
