Signal Transfer PointSignal Transfer Point

The SVI_STP is a feature rich and future proof carrier grade telecommunications Signal Transfer Point that provides core network connectivity and routing between multiple networks supporting legacy SS7 TDM, NGN IP SIGTRAN and IMS / LTE / 4G support.

Complex Routing

The SVI-STP Signal Transfer Point features highly flexible routing options with regular-expression based manipulation of outbound message contents.

Flexible MSU Record Capture

stp flex msu records

 

The SVI-STP provides a flexible mechanism for the capture of all MSU messaging storing as:

  • ASCII based MSU records
  • Configurable ASCII based CDRs
  • Store MSU details in SQL database
  • MSU duplication enables messages to be sent to 3rd party applications - ie. monitoring

Allows operators to perform Billing Reconciliation, Network Analysis etc.

1+1 Redundancy

stp 1plus1redundancy

 

  • 1+1 Dual Plane Worker/ Hot Standby
    - Database and signalling information check-pointed between planes
    - Replicated hardware and software
  • Eliminates single points of failure
  • Five Nines uptime (99.999%)
  • Single Point Code spread across dual plane architecture
  • Single OA&M interface over VIP address
  • Real time Maintenance upgrades

Mated Pair Redundancy

stp matedpairredundancy

 

  • Standard SS7 based mated pair redundancy support
  • Replicated hardware and software
  • Eliminates single points of failure
  • Five Nines uptime (99.999%)
  • Offers diverse routing possibilities to interconnects
  • Capability/Floating point code support
  • Geo-Redundancy is possible

1+1 Redundancy combined with STP Mated Pair

stp combinedmatedpair

 

  • Combines 1+1 Redundancy with a mated pair
  • Replicated hardware and software
  • Eliminates single points of failure
  • Five Nines uptime (99.999%)
  • Offers diverse routing possibilities to interconnects
  • Geo-Redundancy is possible

Real Time Fraud Prevention

stp fraudprevention

 

The annual loss globally to the Telecoms industry from fraud is currently estimated by the CFCA (Communications Fraud Control Association) to be $29.2 billion.

Enable the real-time Fraud Prevention Gateway, the SVI-FPG, to:

  • Combat SS7 fraud in real-time
  • Proactively block, tear-down, transfer and redirect fraudulent calls
  • Seamless interface to upstream firewall and monitoring applications
  • Deployed in non-critical path of network
  • Rapidly provision network lookups aimed at identifying fraudulent traffic

Private SS7 Networks

stp privateSS7

 

Deploying the SVI_STP into an existing SS7 network allows an operator to generate its own “Virtual Point Codes” for transparent single carrier PC interconnect and provision of “private SS7 networks” providing:

  • Costs savings by not having to purchase expensive incumbent carriers Point Codes.
  • Accelerated network deployment - the provision of additional Point Codes and inter-op testing is managed by the operator.

Signalling Relay Function

Integrated Signalling Relay Function:

  • Seamlessly enables Mobile Number Portability

    Manage interface between GMSC’s + HLR’s
    - SCCP Call Steering
    - Call Control Triggering

  • Integrate over a range of API’s
    - JSON
    - SQL
    - ENUM

  • Support for 3GPP TS 23.066
