Abstract

The invention relates to the field of communication, and in particular relates to a dialing box and a communication system. The dialing box comprises a microcontroller, a USB interface, a serial portchip, a USART interface, a RJ11 port, a first I / O interface and a second I / O interface, wherein the serial port chip is connected with the USART interface via the USB interface, the USART interface isconnected with the microcontroller, and the microcontroller is connected with the RJ11 port via the first I / O interface, and connected with the microcontroller via the second I / O interface. The dialing box is low in cost and high in dialing efficiency.

Description

technical field [0001] The patent of the present invention relates to the communication field, in particular to a dial box and a communication system. Background technique [0002] At present, people's dialed calls are independently connected to the outside line of the telephone, and the dialing of the telephone is completed by manually operating the telephone keyboard. [0003] Although there are telephones or dialers with one-key fast dialing function on the market, because the information storage capacity of the telephone is small, the external memory can solve the storage problem, but the corresponding cost will also increase accordingly. Therefore, in the storage capacity Under the problem of low cost and high cost, the existing dialer can only realize a small part of automatic dialing, but most of the phone numbers still need to be manually entered, which is prone to errors during use and affects the user experience. Contents of the invention [0004] The purpose of...
