establish, maintain and tear down an actual physical circuit for each voice call.
Calient's LightConnect Fabric Manager allows data center operators to reconfigure the optical layer of their data centers by managing and orchestrating pure-optical connections in a fabric consisting of multiple S-Series Optical Circuit Switches
McDowell: At its core, the debate pertains to what rules should or should not apply as networks transition from traditional circuit switched
networks to all IP networks.
However, significant differences exist between a GSM voice system that is circuit switched
and a GPRS or EDGE system that is packet routed.
In order to prepare for this change, telecommunications networks should upgrade their circuit switches
to packet switches, which can more effectively handle high-speed data, Technology Futures advises.
An IP telephony network is inherently more efficient than a circuit switched
telephony network and improves capacity while lowering costs.
Orange is using a technology called high-speed circuit switched
data (HSCSD) rather than the general radio service (GPRS) system favoured by the UK's other operators.
Other features include support for both circuit switched
interfaces such as TDM and IP network interfaces, 99.999% or better availability and a small footprint.
This will include the new Nokia UltraSite - a multimedia-ready base station supporting high speed circuit switched
data (HSCSD), General Packet Radio Service (GPRS), Enhanced Data Rates for Global Evolution (EDGE) and Wideband Code Division Multiple Access (WCDMA) services.
Regular phone calls may travel through several circuit switches
, while Internet calls need to travel through the gateway only twice: once to turn it to digital form and once to change it back.
A notable feature of this service is that the mobile can send and receive short messages while it is engaged in a circuit switched
(telephony or data) call.
1 for mobile voice telephony for the second time in a row with the legacy circuit switched
voice service, according to the most recent mobile benchmark test by independent magazine Connect.
