Abstract
A gateway is provided. The gateway (10), connected to a telephone (30) via a telephone network (20) includes a storage module (110), a detecting module (130), and an adjusting module (150). The storage module stores a signal intensity adjusting table, including multiple adjusting levels, and multiple adjusting values corresponding to the multiple adjusting levels respectively. The detecting module detects a tip voltage and a ring voltage of the gateway. The adjusting module computes a line impedance according to the tip voltage and the ring voltage, computes an adjusting level according the line impedance, and adjusts the signal intensity according to the adjusting value in accordance with the adjusting level by inquiring the signal intensity adjusting table. A method for adjusting signal intensity between the telephone and the gateway is also provided.
