NGN Global Ltd design and deploy Next Generation Networks. Next Generation Network is the term given to radically new core network infrastructure and associated access network of Telecommunications Companies (Telcos). These new single network infrastructures replace decades of multiple networks each providing a specific type of service and typically overlaid on each other.The new single core network utilises the standards and technologies of the Internet as the native common platform for all telecommunications services, including telephony (voice), data and video. In other words, where once, say, a data network was derived from an underlying voice switching and transmission network using additional specialist equipment overlaid on an end-to-end basis throughout the Telco infrastructure, now data communications sits alongside telephony using the same network switching and transmission elements. In fact, what was "data over voice" has now become "voice over data" as, essentially, NGN Networks use data networking as the core rather than telephony networking as had been the case from the earliest days of the industry.
