Inventor: TAKAHASHI KAZUHIDE
IPC: H04Q3/545
Filed: 1993-03-29
Abstract: PURPOSE:To automatically update a database for recognizing a present condition of the package of a board by reading the specification identification mark of the board, transmitting it to an operation system, updating a storage means, and reading and collating data by each electronic switchboard when the board is inserted into or pulled out from the switchboard. CONSTITUTION:When one board 10 which stores the board number applied by a board number management table in a storage part 11 is inserted into or pulled out from one slot 13 of one of ESSx (electronic switchboard), the slot 13 detects the insertion/pulling-out, writes the mark of the state in a storage part 15, and communicates the insertion/pulling-out to a board number reading part 14. The reading part 14 reads the state of each slot from the storage part 15, and discriminates whether the state is insertion or pulling-out. The reading part 14 reads the slot number from the storage part 15, transmits it through a reading communicating part 15 to an OPS(operation system), and rewrites the state value of the storage part 15 from pulling-out to the absence of the board. The OPS which receives the communication deletes the ESS number, slot number, and board number from a board package table 32.
