TCS: Telephony Control Protocol Specification
The Telephony Control Protocol Specification (TCS) is a protocol in the Bluetooth protocol stack that defines ways to send audio calls between Bluetooth devices. It also controls the device mobility management procedures. It can be used to create a three-in-one phone:
1) On the move, a mobile phone connected to a cellular network;
2) At home, a cordless phone connected to a PSTN via a gateway or base station;
3) At the office, an intercom.
