In a line accommodation circuit for use in combination with a cell exchange apparatus to carry out a conversion operation of a sequence of input data signals into a sequence of asynchronous transfer mode cells sent to the cell exchange apparatus, first and second function systems which are identical in structure with each other are supplied with the input data signals in parallel and are switched from an active system to a standby system by a switching operation indicated by a system controller. During the switching operation, the active system stops the conversion operation and produces the asynchronous transfer mode cells left therein while the standby system starts the conversion operation to produce a following asynchronous transfer mode cell. A test cell is inserted in the active system after a last one of the asynchronous transfer mode cell held in the active system and placed in the standby system before a following asynchronous transfer mode cell following the last asynchronous transfer mode cell. The test cell is at first detected by the standby system and thereafter detected by the active system. When the test cell is detected by both the active and the standby systems, the next asynchronous transfer mode cells succeeding the following asynchronous transfer mode cell are sent from the standby system which is rendered into a new active system. The active system which interrupts the conversion operation is rendered into a new standby system.
