摘要： This invention relates to a subrack device applicable for an SDH network, and more particularly to a subrack device which can be produced flexibly in response to a customer's need. The subrack device has a subrack body commonly used regardless of a type of the subrack device. The subrack body has a circuit-board-unit housing portion and an outer-connecting-board mounting portion. Circuit boards and outer-connecting-board connecting-boards of different types are prepared. The outer-connecting-board mounting portion has a plurality of outer-connecting-board mounting territories. The outer-connecting-boards are plugged in the outer-connecting-board mounting territories to produce the subrack device meeting the customer's need.
