Title: Method for detecting ring signal in telephone network
Inventor: SEO CHANG GYU
IPC: H04M1/00
Filed: 1998-09-12
Abstract: PURPOSE: A method for detecting a ring signal in a telephone network does not add a noise removing part of a hardware structure even if a noise is added in a ring signal, and detects a ring signal without error. CONSTITUTION: A method for detecting a ring signal in a telephone network sets (a) an initial value for setting a low period judgment allowance range, a high period judgment allowance range, a ring pulse judgment value, and an error allowance value. The method judges whether a ring detection interrupt is generated, and sets (b) a flag for a ring detection. If the ring detection interrupt is generated, the method counts a low level period and a high level period of a first ring signal at a predetermined interval. If the counted values are included in the low/high judgment ranges, the method performs a step(d). If the counted values are not included in the low/high judgment ranges, the method performs the step(b). The method sequentially counts a low level period and a high level period of a ring pulse at a predetermined interval. If the counted values are not included in the low/high period judgment ranges, the method operates an error counter. If the counted values are included in the low/high period judgment ranges, the method operates a ring pulse counter. If the error counter value is an error allowance value, and a value of the ring pulse counter is higher than the ring pulse judgment value, the method generates the ring detection signal. Thereby, a production cost is reduced, and a ring signal is more accurately detected.
