LINE RESERVATION CONNECTION METHOD

PURPOSE:To attain advance path setting to a conference terminal equipment not in the active state with respect to the line reservation connection method setting a path between conference terminal equipments in advance. CONSTITUTION:This method is a line reservation connection method by which a path is set among plural conference terminal equipments accommodated in different exchanges prior to the communication start, and a 1st conference terminal equipment 2a accommodated in a 1st exchange 1a makes a call to a 2nd conference terminal equipment 2b accommodated in a 2nd exchange 1b, the 1st exchange selects the line 3a to make connection processing to the 2nd exchange. In this case, an incoming call processing means 4 of the 2nd exchange allows an incoming call connection processing section 5 to make normal connection processing when the 2nd conference terminal equipment is an operation enable state and allows a reservation connection processing section 6 to make a notice during terminal calling when the 2nd conference terminal equipment is not an operation enable state and thereby connecting the 1st conference terminal equipment and the 2nd conference terminal equipment through a line. Thus, when the 2nd conference terminal equipment is in the active or dialing state, the 1st conference terminal equipment and the 2nd conference terminal equipment are set to the communication state.
