This call path 25 is classified by subscriber rank, for example, public telephone, emergency telephone, etc.
They are ranked in order of special telephones, other general telephones, etc. Therefore, power consumption for each trunk package can be reduced by restricting calls starting from the lowest subscriber rank. Since this communication path 25 consumes high power due to the subscriber loop current of -48V during a call, the battery holding time can be extended by regulating the communication path quickly in the event of a power outage. Conventionally, it took 3 to 6 hours to reach the discharge limit of a pantry, but by controlling the communication path, the time can be more than doubled.
