SS7 to NFAS Converter

SS7 to ISDN Signalling Converter

The SVI 9220 provides a signalling only conversion solution for SS7 to ISDN signalling interworking when using an NFAS interconnect to the ISDN equipment.

NFAS allows for a single D Channel to support multiple Bearer channels spread across multiple interfaces. This follows a similar model to SS7 and allows for bearer channels to be connected directly between the SS7 and ISDN equipment. This allows for the reduction in hardware on the protocol converter.

Squire Technologies provide, through their custom product development services, a number of proprietary APIs for client specific requirements :-

• Simplified access to a subset of SS7 protocols – i.e.
  • MAP i.e. Specialised HLR lookups, MAP / GSM monitoring for location based services
  • TCAP i.e. Message Waiting Indicator, CNAM, LNP
  • ISUP i.e. simplified call control
• API presented over IP or through C library calls
