Time slot dynamic allocation circuit for digital communication equipment and running method thereof

Abstract

The invention discloses a time slot dynamic allocation circuit for digital communication equipment, and a running method thereof. n E1 signal interface circuits of a circuit are connected with FIFO (First In First Out) registers respectively; a clock signal circuit is connected with a time slot pulse circuit, and is accessed to each FIFO register; each FIFO register is connected with an adder through an on / off switch; the fixed contact of a change-over switch is connected with the time slot pulse circuit, a first change-over contact is connected with an FIFO register enabling end, and a second change-over contact is connected with an IP (Internet Protocol) adder; a singlechip control signal 1-n is connected with each switch; an IP signal interface circuit and the clock signal circuit are connected with an IPFIFO register; the IPFIFO register is connected with an adder through an IP on / off switch; the IP adder is connected with an IPFIFO register enabling end; and a singlechip is connected with the IP on / off switch through the control signal of an IP channel. In the running method, each E1 signal interface circuit is used for detecting the state of an input signal, a result is transmitted to the single-chip microcomputer, the single-chip microcomputer is used for controlling each switch, and an IP signal is transmitted via an idle E1 time slot. According to the time slot dynamic allocation circuit and the running method, time slot dynamic allocation is realized, and the transmission efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of digital communication, in particular to a time slot dynamic allocation circuit and an operation method of digital communication equipment. Background technique [0002] Mobile communication is the leading wireless communication system, including digital microwave communication, wireless local area network (WLAN), direct broadcast service (DBS), local multipoint distribution system (LMDS) and radio frequency identification system (RFID), etc., are developing rapidly today. Microwave communication technology is playing an increasingly important role in the entire wireless communication system. With the increasing improvement of digital microwave communication, the communication system is constantly updated, the system capacity is getting larger and larger, the speed of information transmission is getting faster and faster, and the types of information being transmitted are becoming more and more abundant. ...

Problems solved by technology

The disadvantage is that when some services do not need to be transmitted, they will also occupy fixed time slots, and the idle time slots occupy channel resources, reducing the transmission bit rate and causing great waste

Moreover, it can only transmit the service electrical signal E1 in the existing digital communication, and cannot transmit the network IP signal at the same time, which cannot meet the multi-service access requirements of the access network of modern digital communication.
