Output value control method and transmission apparatus

摘要

The object of the present invention is to reliably prevent deterioration and failure of reception relevant parts in a transmission apparatus on a reception side without using an attenuator. An output value control method that controls an output value of output information transmitted from each of transmission apparatuses, in which a transmission apparatus transmits the output information having a minimum output value as the output value to the other transmission apparatus, and when the output information does not reach the other transmission apparatus, the transmission apparatus repeats transmission of the output information after increasing the own output value by adding a predetermined value to a previous output value, and then the other transmission apparatus that has received the output information calculates the output value of the transmission apparatus, and notifies the calculated output value of the transmission apparatus as an appropriate output value to the transmission apparatus.

主权项

1. An output value control method for controlling an output value of output information transmitted from each of transmission apparatuses including a first transmission apparatus and a second transmission apparatus between which the output information is transmitted and received by the transmission apparatuses, comprising the steps of;
the first transmission apparatus transmitting the output information having a minimum output value as the output value to the second transmission apparatus which is different from the first transmission apparatus as well as notifies the minimum output value as an own output value to the second transmission apparatus, the first transmission apparatus repeating a transmission of the output information and a notification of the own output value at the time of the transmission after increasing the own output value by adding a predetermined value to a previous output value when the output information does not reach the second transmission apparatus, the second transmission apparatus receiving the output information calculating the output value of the first transmission apparatus on the basis of the notified output value, and notifying the calculated output value of the first transmission apparatus as an appropriate output value to the first transmission apparatus, and the first transmission apparatus transmitting and receiving information to and from the second transmission apparatus with the notified appropriate output value.
