E1 protocol converter with indication interfaces

Abstract

The invention discloses an E1 protocol converter with indication interfaces. The E1 protocol converter comprises a complex programmable logic device CPLD, a field programmable gate array FPGA, a microprocessor, a plurality of interface chips and indicator lamps. The interface chips include a plurality of multifunctional interface chips and E1 line interface chips, the multifunctional interface chips are conducted with the complex programmable logic device CPLD in a two-way manner, and the E1 line interface chips are conducted with the field programmable gate array FPGA in a two-way manner; the microprocessor is conducted with the complex programmable logic device CPLD in a two-way manner and is conducted with the field programmable gate array FPGA in a one-way manner; the indicator lamps are connected with the complex programmable logic device CPLD. The E1 protocol converter with the structure has the advantages that running conditions of various data time slots inside the complex programmable logic device CPLD can be timely reflected, so that corresponding adjustment can be carried out, and the complex programmable logic device CPLD is in the optimal working state.

Description

technical field [0001] The invention relates to the communication field, in particular to an E1 protocol converter with an indication interface. Background technique [0002] With the continuous development of computer technology and communication technology, people's demand for high bandwidth continues to increase, and the application of access to high-speed communication networks such as DDN (Digital Data Network) networks and frame relay networks is becoming more and more common. E1 is the transmission standard used by the primary group of my country's telecommunication transmission network, and the rate is 2.048 Mb / s. Realize the mutual conversion between multi-channel interface and E1 protocol, it will be possible to connect multiple devices to high-speed E1 line at the same time. The protocol converter can make the hosts using different high-level protocols on the communication network still cooperate with each other to complete various distributed applications. Ther...
