A TOWER MOUNTED AMPLIFIER GAIN ADJUSTING METHOD, SYSTEM AND THE TOWER MOUNTED AMPLIFIER

摘要

A method and a system for gain adjustment of the Tower Mounted Amplifier and the Tower Mounted Amplifier are provided. The method includes: sending information indicating whether the current TMA supports the non-linear adjustment and a step value of the non-linear gain adjustment supported by the current TMA from the TMA to a maintenance end; performing non-linear adjustment to the gain of the current TMA non-linear according to the received step value of the non-linear gain adjustment when the maintenance end determines that the current TMA supports the non-linear gain adjustment according to the received information. The embodiments of the present invention effectively solve the problems that an original interface can not express the actual demand clearly and can not obtain whether the gain of the current TMA is adjustable or not and so on.
