The terminal equipment of the called extension uses the call control program to check its own state thereby returning an identification signal representing the idle state or the connection disable state. When the extension terminal equipment is in the idle state, call to the terminal equipment is started, when it is in the connection disable state, the code of the next digit is extracted.

When it is discriminated not to be a section signal, a busy tone is sent to the caller extension terminal equipment.
