Problems solved by technology

For the prior art, any 3 of the remaining 30 endpoints are generally used, for example, as Modem control input endpoints, Modem input endpoints and Modem output endpoints, but so can only be controlled by the input and output of Modem, and realize single group field operation
In the existing technology, if it is necessary to realize the operation of the circuit domain and the packet domain business at the same time, it is necessary to add or modify the hardware on the basis of the original hardware, resulting in an increase in cost

Abstract

The invention provides a universal serial bus modulator-demodulator module, which is connected to a computer. The universal serial bus modem module comprises a modulation / demodulation control input endpoint, a modulator-demodulator input endpoint, a modulator-demodulator output endpoint, a modulation / demodulation command input endpoint and a modulation / demodulation command output endpoint, wherein the modulation / demodulation control input endpoint is used for controlling the connecting state of the serial bus modulator-demodulator module and the computer, the modulator-demodulator input endpoint, the modulator-demodulator output endpoint and the modulation / demodulation control input endpoint form a grouping domain module, and the modulation / demodulation command input endpoint and the modulation / demodulation command output endpoint form a circuit domain module. The universal serial bus modulator-demodulator module provided by the invention has the advantages of simple setting and convenient use, and can simultaneously realize the circuit domain and the grouping domain business operation without changing hardware.

Description

Technical field [0001] The present invention relates to the field of communication, and in particular to a universal serial bus modem module. Background technique [0002] The multiplexing function of the serial universal asynchronous receiver-transmitting machine enables the modem (Modem) module to have the Class B function of the mobile terminal, that is, to realize the operation of circuit domain and packet domain services at the same time. Today, the Universal Serial BUS (USB) interface has become the standard peripheral interface for personal computers and embedded devices, and will gradually replace various traditional peripheral interfaces such as serial ports and parallel ports. Peripheral interface, USB interface has many characteristics and advantages: unified connectors of various interface devices, plug and play characteristics, "hot attach and detach" characteristics, and standard transmission of 12Mbps Speed ​​and higher transmission rate, up to 127 devices can be ...
