Circuit-switched technologies traditionally utilised by carriers are slow and expensive to maintain when compared to Gigabit Ethernet. Gigabit Ethernet will be used to fortify the backbone of LANs and MANs and may intrude into traditionally...
Or their existing Synchronous Digital Hierarchy (SDH) network, to be precise. SDH provides the reliability of circuit-switched pathways and resiliency should there be a fault but it is overly complex and not nearly as flexible as a native IP...
It will develop, manufacture and market wireless products based on Time Division Synchronous Code Division Multiple Access (TD-SCDMA), an emerging 3G standard. TD-SCDMA supports data transmission at speeds of up to 2 megabits per second and...
Also required is a converter for connecting your phone line to the internet. Unlike Skype and FWD, Bellster lets users reach the public switched telephone networks anywhere in the world where there is a member gateway.
But this is the first time a PSTN (public switched telephone network) has been ported to IP. And the UK's public switched telephone network (PSTN) is expensive to maintain. Initially calls will remain switched from the premises to the exchange.
Alcatel, Ciena, Cisco, Ericsson, Fujitsu, Huawei, Lucent and Siemens have all been selected to supply equipment and services that will allow BT to replace today's circuit-switched networks with a single IP-based network.
