Claims

A time switching method of a digital access device, comprising: a first process of initializing a system, allocating a 2B channel per subscriber terminal, and initializing a time slot number of the subscriber to prepare for time switching; The second process of checking whether the subscriber's channel is connected according to the B channel information by the call control program, and whether the originating and the incoming call are connected in the first process, and the incoming and outgoing connection date and time and the called party's time switching information. A third process of forming a switching path, a fourth process of processing a connection result bit according to a state by checking whether the connection is normally performed after performing the third process, and the originating time of the connection time at the originating time in the third process After the switching path is formed by the switching information, the fifth process proceeds to the fourth process, and the other party is temporarily connected to the called party at the third process. After the switching path is formed by the imswitching information, the sixth process proceeds to the fourth process, and in the second process, both the transmission and reception of the communication path recovery date and time and the incoming call recovery are checked. A seventh process of restoring the switching path based on the information, an eighth process of checking whether the restoration is normally performed after the seventh process is performed, and processing and returning a recovery result bit according to the state; After restoring the switching path by the temporary source side time switching recovery information, the ninth process proceeds to the eighth process, and in the seventh process, after the switching path is restored by the called party's recovery temporary destination time switching recovery information. And a tenth step proceeding to the eighth step.
