Problems solved by technology

When the device has been used for a period of time, the protocol converter on the client side is damaged, and when another type of protocol converter is replaced, it is necessary to manually re-identify the corresponding buffer area of ​​the data buffer module through the MCU module. As n becomes larger , the less flexible it is, the higher the cost of installation and operation and maintenance

Embodiment Construction

[0026] As shown in Figure 3, the present invention a kind of convergent protocol converter that automatically recognizes the HDLC / GFP type client protocol converter, mainly includes convergent Ethernet interface unit 1, Ethernet data exchange module 2, Ethernet data cache module 3 , HDLC / GFP automatic processing module 4, VCAT&LCAS module 5, E1 framer / deframer 6, E1 mapper / demapper 7, multiplexer / demultiplexer 8, serial / parallel converter 9, optical interface unit 10 and MCU module 11;

[0027] Among them, the converged Ethernet interface unit 1: used to convert x-channel electrical signals into x-channel Ethernet data signals and transmit them to the Ethernet data switching module 2, or convert x-channel Ethernet data signals from the Ethernet data switching module 2 Converted into x electrical signal and sent out;

[0028] Ethernet data switching module 2: divide the x-way Ethernet data transmitted by the converged Ethernet interface unit 1 into y (x≤y)-way Ethernet data af...

Abstract

The invention discloses a convergent protocol converter and a transceiving method thereof for automatically recognizing high-level data link control (HDLC) / generic framing procedure (GFP) user side protocol converters. An HDLC / GFP automatic processing module is arranged between an ethernet data-caching module and a virtual concatenate (VCAT) and link capacity adjustment scheme (LCAS) module, thereby automatic HDLC and GFP framing / deframing of a local side single convergent converter is achieved, the transmission of information with multiple far-end single way, multiple ways, HDLC type or GFP type E1 protocol converters is achieved, by means of the mode, the automatic identification can be performed when the user side changes different types of protocol converters, and a system which is high in cost performance ratio and compatibility and convenient to install and maintain can be flexibly achieved.

Description

technical field [0001] The invention relates to a convergence type protocol converter for automatically identifying the HDLC / GFP type client protocol converter and a sending and receiving method thereof. Background technique [0002] In the traditional point-to-point coordinating access solution, one dedicated data line is opened, and a converter, a network cable to the switch, and a 2M cable to the DDF (digital distribution frame) are required in the central office room, and then the DDF is transferred to reach the Transmission equipment, so as to reach users through the transmission SDH network. However, with the continuous development of data dedicated lines and the increasing number of user-side converters in the computer room, data dedicated line equipment takes up more and more space in the computer room, and more and more cables and DDFs are used. In addition, the possible fault points involved However, it is impossible to monitor the status of the converter in real ...
