Abstract

DC60 (22/05/41) in communication network system. The range of aggregation between the number of communications lines is less than the number of endpoints of the subscriber in the central location with the number of lines connected to the public and the public switched telephone network (PSTN). Call an emergency from one of the operator's terminals to, for example, police, fire. Line which was performed Communicate to call Emergency calls during the tunneling will be held on hold for a predetermined period of time after the emergency call communication is cut off. When repeated alarms were given Generated by the police, fire, to the consumer's terminal within a predetermined time, a call signal will be transmitted to the The end of the user Through a line that is leveled during the channel aggregation Even if Early signs Is generated from the user's terminal Service to the police Extinguish the fire within the preset time. The initial signal was correct. Passed to the fire police through a line that was leveled in Channel aggregation range The management table will be used to hold calls during a channel syndication. In communication networks Which has the channel aggregation range of the number of communication lines That is less than the number of endpoints of the users in the middle location with the communication line connected to the Use a number of services and a public switched telephone network (PSTN) when making an emergency call from a terminal. Of service users to, for example, police, fire Calls, which have been communicated to make calls Emergency calls during the tunneling will be held on hold for a predetermined period of time after the emergency call communication is cut off. When repeated alarms were given Generated from the police, fire, to the consumer's terminal within the preset time. Will be passed to The end of the user Through the line being held on hold Set during the channel consolidation Even if Early signs Was born from the consumer terminal to the police Extinguish the fire within the preset time. The initial signal was correct. Passed to the police fire Through the line that was held in Channel aggregation range The management table will be used for hold in Channel aggregation range
