Abstract

PURPOSE:To prevent the use of telephone sets in a rental room or the like without giving notice, by arbitrarily setting a secret code dial from the telephone sets for the outgoing restriction and release such as toll call and calls for special areas of telephone sets. CONSTITUTION:When the request of outgoing call restriction for a telephone set from a terminal telephone TEL is made, dialing for the request code and the content of restriction is made, the central controller CC receives it via an outgoing register ORT and records the said information to a telephone set corresponding area of a storage device MM. The central controller makes restriction for toll call and international call or the like by collating the content of the storage device. In releasing the restriction, the central controller analyzes the restriction release request code and a secret code dialed from the telephone set and changes the restricted information for the area corresponding to the telephone set in the storage device for the release of the outgoing call restriction.
