<p>PURPOSE:To display communication enable sections actually and disable sections distinguishingly without difference in a fact by applying discrimination such that communication disable display is applied to the remaining one transmission line when communication disable display is applied as to (N-1) lines among N-set of transmission lines connected to one branch point. CONSTITUTION:The algebraic sum of communication quantity supplying to/ received from each branch at each node of a communication network is zero except the node start point and the end node point, and discrimination is applied with an item added newly that the remaining one transmission line is subject to communication disable display when (N-1) lines are displayed of communication disable among N-set of transmission lines connected to one branch point. Thus, a defect that a fault of the transmission line is not displayed properly depending on the arrangement of line terminators and a fault state is eliminated and a fault is displayed properly.</p> |
