What Does Line Load Control Mean?
Line load control is the equipment or mechanism that is employed in telephone systems to ensure that line overloading does not interrupt the continuous delivery of service. A line load control accomplishes continued service mostly by temporarily denying service in some or all non-essential lines to ensure the service on essential lines is not interrupted. It is a network-provided service feature and it selectively denies call origination to certain lines based on criteria that determine their priority. It helps in balancing the demands and ensures quality of service required by a switching center.
Techopedia Explains Line Load Control
Line load control selectively restricts calls to certain lines during emergencies or overloading conditions to ensure essential traffic is not interrupted. In a typical line load control arrangement, the lines are categorized into classes of significance or importance. For instance, the lines at the switching center may be classified into three classes: A, B and C, where A represents the most essential lines which may be used in national defense or emergency situations. The other classes may represent all other lines. When a line overloading condition occurs, the calls originating from lines that are classified as B or C are denied so that the essential lines from class A are not interrupted.
