SVI_9225 SS7 to PRI ISDN Protocol Converter
The SVI_9225 SS7 to PRI ISDN Protocol Converter product provides cost effective, scaleable SS7 to ISDN conversion.
The product has a high pedigree of worldwide signalling interconnect in over 50 countries catering for both a small interconnect up and large international points of presence.

The SVI_9225 SS7-ISDN Protocol Converter is a fully-featured, carrier-grade product with a flexible and powerful routing engine. This allows for complex routing to be set up on the unit, enabling the routing of any protocol circuit to any protocol circuit and manipulation of the outgoing call details dependant on incoming call criteria. Detailed onboard Call Data Records (CDR) can be produced to both provide billing information and network performance statistics.
A comprehensive Operation Administration and Maintenance (OA&M) interface provides complete onboard or remote control of the SS7-ISDN Converter allowing real-time configuration of system resources. Asynchronous real time traps provide an instantaneous update of all changes in system resources and detailed log files allow configurable levels of debug.
The SVI_9225 supports full SS7 redundancy in a worker / standby architecture across dual planes ensuring carrier-grade reliability and resilience to network failures.
With comprehensive support for R2 available on the SVI_9225 it provides a flexible product allowing rapid protocol interconnect into legacy and incumbent TDM networks.
The SVI_9225 SS7-ISDN Protocol Converter has many uses within the Telecoms network providing a quick and cost effective way of upgrading existing ISDN incumbent equipment to support SS7. These uses include enabling service providers to obtain lower call minute rates by moving from ISDN to SS7, allowing ISDN service providers to terminate revenue generating calls directly on their equipment to transit to other providers. Alternately the SS7 to ISDN Protocol Converter provides a simple solution to interconnecting non SS7 enabled VoIP media gateways into the PSTN network.
Hardware Options
The SVI_9225 SS7-ISDN Protocol Converter is provided in three different form factors: Compact, Standard and Extended. The Compact provides a high performance, low density signalling environment in a small foot print 1U high chassis. The Extended chassis is a 2U high chassis providing greater density signalling and PCM cross connect. Lastly the 4U high chassis provides the highest signalling density and a higher specification of hardware redundancy in a single chassis.
The Standard and Extended chassis can be upgraded by 4E1 and 8E1 Signalling Card upgrades providing a flexible and scaleable protocol converter model.
