Purpose: one No. 7 signal network management agreements by storage and branch access Status Change information to multiple signaling points be arranged to reduce a signal link combination and an a large amount of signaling points, extension forbid transmit (XFP) or extend allow transmitting (XFA) message in. Construction: in one No. 7 signal network management agreements, when the signal link being arranged to an available mode transition, one XFP message is transferred to by an available signal link combination heat to (TFP) message of forbidding transmitting of each signaling point communication using a corresponding signal trunk group. When the useless signal link being arranged to an available mode transition, allow to transmit (TFA) message heat using one of each signaling point that can be close to of a corresponding signal trunk group and is transferred to a consecutive points, another signal link of signal link combination, XFA message access are wherein replaced by setting. XFA message is generated, and is then combined heat by an available signal link and is transferred to an adjacent signal point. XFP message includes counting (n), it indicates the quantity of forbidden signaling point, destination (the 1) _ destinations L- (n) _ L, it indicates the eight more low levels for becoming the signaling point coding that access is forbidden, destination (the 1) _ destinations H- (n) _ H indicates six upper bits for becoming the signaling point coding that access is forbidden.
