Abstract

The invention discloses a cordless telephone switchboard for a group and relates to the cordless telephone switchboard for the group. In order to solve the defects that the traditional wired telephone switchboard has a complicated line, a network fault is maintained difficultly, communication from the existing wireless switchboard to the switchboard cannot be carried out, and the expandability is weak, when an external phone call is coming, a ring, a number and an analogue audio output signal are separated out from a local call signal through a host computer system telephone interface module; the ring signal and the number signal are transmitted to a single chip module to process; an audio signal is converted into a digital signal to be transmitted to the single chip module for processing through an audio sampling encoding module; the single chip module transmits the signal to the host computer system radio transceiver module; the host computer communicates with a slave computer through a radio module; and a slave computer system single chip module transmits a digital audio signal to an audio decoding module, converts the digital audio signal into an analogue audio signal, and transmits the analogue audio signal to a telephone interface module through the radio transceiver module to achieve multi-user transmission. The cordless telephone switchboard for the group disclosed by the invention is suitable for the field of communication.

Description

technical field [0001] The invention relates to an exchange, in particular to a group cordless telephone exchange. Background technique [0002] At present, digital voice switching technology is mainly used in group telephone exchanges. The PBX is composed of outside lines and extensions. It consists of several telephones sharing one or more outside lines, used for small and medium-sized businesses, and can also be used for residential and secretary telephones. When an outside line calls in, it can be answered by any phone, and can be transferred to the desired called party. Group telephone exchange technology is a common means of communication management in modern offices, enabling telephone administrators to collectively manage incoming outside calls and outgoing inside calls. In recent years, with the development of our country's economy, the output of communication equipment including PBX has increased significantly. With the wide application of switch technology, my...
