Definitions for "Circuit Switched Data"
Is a data bearer that is available on GSM networks. It is one of the bearers for working with Wireless Application Protocol (WAP)
Phone calls with data only instead of voice.
This is the technique that is used when a complete circuit is dedicated to a particular data channel. The destination address is implicitly defined by the circuit that is selected. It offers a simple solution to sending data over a channel, although it is not as efficient as packet switched data because channel usage can be low and the channel cannot be shared.
