Plain old telephony service (POTS) call processing equipment, system and method

Abstract

The embodiment of the invention discloses plain old telephony service (POTS) call processing equipment. In the system, current and voltage of a POTS system are sampled by a current sampling unit and a voltage sampling unit respectively; a sampled voltage signal is output to an amplifying unit to be amplified; the voltage signal output by the amplifying unit is converted into a corresponding digital signal; a microcontrol unit (MCU) calculates the surplus power of the POTS system according to the digital signal of an analog-digital (AD) converting unit and the rated power of the POTS system; and a call of the POTS system is processed according to the surplus power calculated by the MCU, so that the problem that the POTS system cannot operate normally due to overload protection of the POTS system when the power is too high during capacity expansion of the POTS system is solved, and the stability of the POTS system is improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a traditional telephone service POTS call processing device, system, and method. Background technique [0002] With the rapid development of semiconductor technology, the integration level of single boards is getting higher and higher. At present, the following technology is used to upgrade the existing traditional telephone service POTS system: under the condition that the power of the system power supply does not change, the number of POTS users can be reached on the POTS single board of the same size by replacing the POTS single board card Multiplied, so as to realize the expansion of POTS users. [0003] When the POTS system is expanded, the rated power P remains unchanged, and the number of ports of the equipment increases after expansion. If the device has M ports after capacity expansion, then when the M ports simultaneously carry out telephone call service...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the embodiments of the present invention is to provide a traditional telephone service POTS call processing device, system, and method, which are used to solve the overload protection of the POTS system caused by the excessive power of the conventional telephone service POTS system in the prior art, As a result, the POTS system cannot operate normally, and the stability of the POTS system is improved.
