PURPOSE:To make the deletion and the re-input work of the same data unnecessary by providing each subscriber's circuit with a rewritable nonvolatile memory storing and registering subscriber data, which is related to a terminal connected to the subscriber's circuit, in the nonvolatile memory when it is inputted from a private console. CONSTITUTION:In case that subscriber data (a) is registered from a maintenance console MC5 to a storage position number M0 on a channel switch SW3 of a subscriber's circuit package LC2, subscriber data (a) is not only stored in an address A0 corresponding to the storage position number M0 of a data memory DM6 through a CPU4 but also stored and registered in a nonvolatile memory LM20 of the LC2. If the storage position of the LC2 is switched from the storage position number M0 to a storage position number M1 in this state, subscriber data (a) registered in the LM20 is transferred to an address A1 corresponding to the storage position number M1 of the DM6 through the CPU4, and hereafter, subscriber data (a) is handled as subscriber data of a terminal 1 stored in the storage position number M1. |
