permitting input of a reserved function key at said first telephone set without disconnecting said second telephone set from said common telephone line, when said second telephone set within said parallel-connected telephone system is in said on-line state;
setting said first telephone set in a reserved speech path mode in response to input of said reserved function key;
determining, at said first telephone set, whether said second telephone set shifts from said on-line state to an off-line state; and

Abstract
A reserved speech path forming method according to a first embodiment includes the steps of: determining whether or not another telephone within a parallel-connected telephone system is being used, enabling input of a reserved function key to reserve the speech path when another telephone within the parallel-connected telephone system is being used, providing a dial tone and enabling input of a reserved telephone number upon completion of use of the other telephone within the parallel-connected telephone system, dialing the reserved telephone number, and forming the reserved speech path. A reserved speech path forming method according to a second embodiment includes the steps of: determining whether or not another telephone within a parallel-connected telephone system is being used, enabling input of a reserved function key to reserve the speech path when another telephone within the parallel-connected telephone system is being used, storing a reserved telephone number input by a user, and automatically dialing the reserved telephone number and forming the reserved speech path upon completion of use of the other telephone within the parallel-connected telephone system.
