AI Technical Summary
Technical Problem
Existing IP telephone systems consume standby power by supplying power to unused telephones, even when employees are teleworking or not present in the office.
Method used
A power supply management system that includes a private branch exchange (PBX) connected to a power supply hub with multiple ports, which receives an identification number for a specific telephone from a user communication terminal, specifies the corresponding port number, and sends a power supply command to the power supply hub to turn on power only for the needed telephones.
Benefits of technology
This solution effectively reduces standby power consumption by ensuring that power is only supplied to telephones that are in use, thereby minimizing energy waste.

Abstract
To suppress the standby power consumption of telephones.SOLUTION: The invention provides a private branch exchange connected to a power supply hub having a plurality of power supply ports, each of which supplies power to a telephone installed at each seat in a working space where multiple seats are arranged. The private branch exchange includes: an incoming call reception unit that receives an incoming call from a user communication terminal, the incoming call being provided with an identification number assigned to a telephone (specific telephone) which is installed at a seat and for which power should be turned ON; a specifying unit that specifies the port number of the power supply hub corresponding to the identification number received by the incoming call reception unit; and a transmission unit that transmits a command to supply power to the power supply port corresponding to the port number specified by the specifying unit.SELECTED DRAWING: Figure 8
