Abstract

PURPOSE:To easily attain the switching of a termination circuit by connecting an input from an incoming line to a 2nd termination circuit during the reception of a packet flag and switching an output to an outgoing line to the 2nd termination circuit when the output is completely lost. CONSTITUTION:When an error is detected in a 1st termination circuit 5 during operation, the incoming line 1 is disconnected from the 1st termination circuit 5 in receiving a packet flag with respect to the input from the incoming line 1 and connects to a 2nd idle termination circuit 6. Then the output to the 2nd termination circuit 6 is permitted when the output to the other termination circuit is lost in the 1st termination circuit 5. Then the output destination being the 1st termination circuit 5 is changed to the 2nd termination circuit 6 for each termination and the output to the outgoing line 2 in the 1st termination circuit 5 is lost, then the outgoing line 2 is disconnected from the 1st termination circuit 5 and connects to the 2nd termination circuit 6. Thus, the termination circuit is switched without intermitting a call and reducing a throughput.
