<p>PURPOSE:To inhibit a terminal, which is in a time zone where it is undesirable that the terminal receives a call, from receiving the call by previously registering the call receivable time of day for each terminal interface and rejecting access from a network side at any time of day except the call receivable time of day for each terminal. CONSTITUTION:A network side interface 100 and two sets of terminal interfaces 121 and 122 are connected through a network side layer 1 terminal circuit 1 and two sets of termination side layer 1 terminal circuits 2A and 2B connected to the respective terminations of the interface 100 and the interfaces 121 and 122. The title adaptor is equipped with a transfer control circuit 4 to control the transfer of a D channel signal from the network side interface, plural incoming call control circuits 6A and 6B to make the D channel signal into an incoming call for the respectively connected terminal interfaces by the command of the transfer control circuit 4, and a clock means 10 to register the respective call receivable times of day of the plural terminal interfaces, and the respective incoming call control circuits control the receiving of the D channel signal from the network side interface at the call receivable time of day of each terminal and control the rejection of the incoming call at the other times of day.</p> |
