Problems solved by technology

And add the processing of J0, J2 trace information byte, then the above-mentioned method also needs more memory
It can be seen that the processing method of trace information in the prior art requires a large amount of RAM, and a large amount of RAM will increase the area and power consumption of the chip, affect the yield of the chip, and greatly increase the cost of the chip

Embodiment Construction

[0051] The present invention provides a processing device and method for trace information in a synchronous digital transmission system. In order to reduce the RAM required for trace information processing, the present invention combines the capturing page and accepting page used in the prior art processing method into a receiving page Page. The following uses the trace information byte J1 as an example to describe the processing method of the trace information in the present invention, which is also applicable to the processing of the trace information bytes J0 and J2.

[0052] The present invention provides a state machine, which divides three states for processing trace information, which are respectively norm, unstable and mismatch states. Among them, the norm state indicates the trace information, that is, the J1 code stream is stable and matches the expected value, the unstable state indicates that the J1 code stream is unstable, and the mismatch state indicates that the...

Abstract

A method for processing trace information in synchronous digital transmission system includes setting up desire page and reception page, judging whether trace information of multi-frame received currently is consistent with trace information stored in reception page or not and generating warning that trace identification character is not stable if number of non-consistent multi-frame is up to setthreshold, judging whether trace information stored in reception page is consistent with desired value of trace information in desire page or not and generating warning that trace identification character is not matched if it is.

Description

technical field [0001] The invention relates to an optical synchronous digital transmission system (SDH / SONET, Synchronous Digital Hierarchy / Synchronous Optical Network), in particular to a processing device and method for trace information in the synchronous digital transmission system. Background technique [0002] The trace information byte is a byte at a fixed position in the mid-stage overhead, high-order path overhead, and low-order path overhead of the synchronous digital transmission system, including J0, J1, and J2 bytes. The trace information byte is used to repeat the sending segment, channel, and branch access point identifier (APID, Access Point Identifier), so that the receiving terminal can confirm whether it is in a continuous connection with the specified sender, so as to track Connection Status. Network providers can use trace information to discover and solve problems in advance, prevent transmitted services from being affected, and shorten network recove...
