technical field

The invention relates to the communication field, in particular to a low power consumption optical network unit and a telephone system.

Background technique

The traditional POTS (Plain old telephone service) telephone has existed for hundreds of years. Under normal working conditions, the POTS telephone is directly powered by the telephone network operating company through the telephone line to meet the requirements of the POTS telephone on-hook, off-hook, ring tone and Voice playback and other aspects of power demand, while the power transmitted in the telephone line and the corresponding optical network unit depends on the local city power. In this case, if the mains power is interrupted due to some unexpected reasons, the power supply required by the telephone users in the affected area is all supplied by the backup battery in the local ONT (Optical Network Terminal) equipment.

However, there is always a time when the power in the backup battery is depleted, and the constant replacement creates additional costs for the phone operator. And because the distribution of the telephone network is intricate, the replacement of the backup battery is also very difficult. Therefore, how to reduce the power consumption of the phone and prolong the service time of the backup battery, thereby prolonging the talking time of the user and the standby time of the phone when the backup battery is used, has always been a concern of the telephone operator.

After research, it is found that according to the provisions of the GB/T 15297-2002 standard for telephone power supply, the ringing of the telephone requires a ringing voltage of 48V and consumes a current of 25mA. Considering the loss of 20% during the voltage conversion process, the ringing of the telephone can consume Losing the 1.5 watt power reserve in the backup battery has caused a great burden on the backup battery, so it is necessary to reduce the power loss of the phone ringing for the backup battery to prolong the service life of the backup battery.
