Flexible MSU Record Capture

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

Allows operators to perform Billing Reconciliation, Network Analysis etc.

1+1 Redundancy

• 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

• 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
• Geo-Redundancy is possible

1+1 Redundancy combined with STP Mated Pair

• 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

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

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
