A common exchange approach provisioning connection of existing SS7 with IP based SIGTRAN network using CPLD driven device

摘要

Now-a-days communication engineering is facing an age of explosive transformation that is both facilitating and influencing the unification of services. Compared to voice, packet data is becoming more significant proportion of traffic. It has become essential to find ways of consolidating voice, data traffic, platforms and services to reduce the operational, maintenance and initial cost of the network. IP based SIGTRAN network is now considered the most promising media on which to build the new integrated services platform which is basically SS7 in the IP packet. As a part of on-going integration of circuit networks and SIGTRAN networks, we have proposed a very cost effective common exchange developed by using CPLD driven device to consolidate existing SS7 network and SIGTRAN network. Our exchange comprises of hardware driven by CPLD, E1 card and ASTERIX software. For SS7 and SIGTRAN protocol configuration, ITU-T and IETF reference documents defined structure is used, which makes the data exchanger software format globally accepted.
