Problems solved by technology

[0003] However, in a synchronous time-division multiplexing transmission system, the time slot of the transmission channel is fixedly occupied by the business transmission, regardless of whether there is business transmission or not, the time slot bandwidth corresponding to the transmission channel is always occupied, resulting in a waste of transmission bandwidth resources

Abstract

The invention discloses a multi-channel service shared channel transmission system based on a synchronous time division multiplexing system. Each service end is communicated with a transmission channel through an FPGA (Field Programmable Gate Array) and a CPU (Central Processing Unit) which are matched with each other; the FPGA realizes monitoring of service data through a serial port end RTP on the FPGA, codes each serial port end to realize service coding through the FPGA, and further enables received and transmitted data of the FPGA to correspond to the serial port end RTP through code recognition; and the CPU communicates with the FPGA through an AD bus, so that dynamic time division multiplexing of multi-channel services and dynamic adjustment of time slot bandwidth of a transmission channel are realized according to a dynamic control signal sent by the FPGA, and the synchronous time division multiplexing of the transmission channel is further realized. The invention provides a multi-channel service shared channel transmission system based on a synchronous time division multiplexing system, which can integrate voice, data services and Ethernet services in a synchronous transmission channel at any rate, realize multi-service integrated transmission and bandwidth sharing, and improve the integration level of a communication system and the utilization rate of transmission channel bandwidth.

Description

technical field [0001] The invention relates to a management system used in the case of synchronous time division multiplexing technology data transmission. More specifically, the present invention relates to a multi-channel service sharing channel transmission system based on a synchronous time-division multiplexing system for synchronous time-division multiplexing service transmission channel sharing to improve the utilization rate of transmission line bandwidth. Background technique [0002] For synchronous communication equipment built on the basis of synchronous time-division multiplexing technology, a certain time slice of the transmission channel is fixedly occupied by a business signal, and the transmission capacity of the communication equipment is often limited by the rate of the transmission channel, and the rate of the transmission channel is limited by the limit of electronic devices. The rate limit has basically reached the limit transmission rate of the TDM te...
