PURPOSE:To attain an unattended mobile line switching station by providing a subscriber registration permission table and a subscriber registration signal sending circuit to the mobile line switching station so as to allow the operator of an optional mobile line switching station to work for the operator of the other mobile line switching station in deputy. CONSTITUTION:When the operator of a mobile line switching station 1 designates a mobile line a switching station 2 and sends an operation intervention signal to it, the switching station 2 discriminates the propriety of the deputy operator by an SID 22 via a communication controller 23 and returns the operation intervention signal to the switching station 1 in discriminating that the deputy operator is available. The operator dials an additional code to identify a destination number desired to be registered and the subscriber registration to the switching station 2. The switching station 2 collates the number of T21 and the additional code with the subscriber registration allowance number of a TBL 24 by the communication controller 23 in the switching station 2, and the subscriber registration signal is sent to the T21 via the subscriber line from the SGS 21 to apply subscriber registration when the both are coincident.
