Class C Terminal

In a GSM and UMTS system a class C mobile is attached to either PS (Packet Switched) or CS (Circuit Switched) services, allowing alternate use only. If both services (PS and CS) are supported then a Class C mobile can make and/or receive calls only from the manually or default selected service, i.e., either Packet Switched or Circuit Switched service.
