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.
