Therefore, the coupling between software and hardware is very strong, which is not conducive to software maintenance—when hardware resources change, the corresponding software processing methods will also change, so the maintenance cost of equipment is extremely high
Moreover, the intelligence level of the equipment is not high, and when the hardware resources are damaged or a physical failure occurs, it is very difficult to maintain and update the equipment

Embodiment Construction
[0034] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0035] Both equipment A and equipment B have a receiver and a transmitter. When the two communicate and the receiver of equipment A receives the signal from the transmitter of equipment B, if the received signal is defective, the transmitter of equipment A will report to equipment B according to the alarm information. The receiving end reports back an indication of a remote defect.
[0036] In the communication process, the method of the specific embodiment of the present invention is applied, and according to the currently detected alarm information, it is determined which type of remote defect indication to send back; then, the remote defect indication is written into the corresponding overhead according to Table 1 Bytes or idle overhead for a certain reservation.

The invention discloses a far-end defective indication method. During the process of communication transmission, when a receiving end receives a defective signal, the far-end defective indication should be returned to a transmission end according to the alarm message. Firstly, according to the present detected alarm message, a first variable of the marked present strengthened far-end defective indication is valued. Secondly, the first variable value is judged whether the value is the same as a second variable of the previous alarm back-inserting strengthened far-end defective indication type or not. If not, then the corresponding type far-end defective indication is reported. The method of the invention is easy and feasible, which requires less to the hardware resource of the equipment. The invention not only decreases the software's rely on the hardware, but also improves the intelligent level of the equipment, which brings more convenience in the running, management and maintenance of the equipment, and greatly reduces the cost.
Description
technical field [0001] The invention relates to the field of optical transmission, in particular to a method for indicating remote defects compatible with various hardware. Background technique [0002] like figure 1 As shown, in optical transmission communication, when the signal received by the receiving end is defective, it needs to report a remote defect indication to the sending end. As shown in Table 1, according to the alarm PLM, UNEQ, TIM, AIS, and LOP detected by the receiving end, three types of remote defect indications (ERDI) can be sent back: ERDI_P, ERDI_C, and ERDI_S. Their meanings are as follows: [0003] PLM: Path signal lable mismatch. Channel ID mismatch warning. [0004] UNEQ: Unequipped. Channel not loaded warning. [0005] TIM: Trace Identifier Mismatch. Trace ID mismatch warning. [0006] AIS: Alarm Indication Signal. Alarm indication signal. [0007] LOP: Loss Of Pointer. Pointer loss warning. [0008] ERDI: Enforced Remote Defect Indicati...
