Abstract
The invention discloses a remote real-time monitoring method for realizing the power-fail warning of communication equipment, which includes the following steps: an embedded control channel is configured and a network element at the tail end tests a power-fail warning indication and generates a power-fail waning message to pass through the channel to be transferred to a downstream network element of a network management server; the downstream network element tests and receives operations unconcerned with warning indication, and reports the power-fail warning message to the network management server. By adopting the downstream network element to report the power-fail warning, relying on the existing physical link to send the power-fail warning information actively and using hardware logic to directly process and send the power-fail warning message, cycles of system design and development can be effectively shortened and the real-time performance, reliability and capacity of resisting disturbance can be improved. The method of the invention not only has high response speed, simple interface and flexible information definition, but also has low cost and good expansibility; simultaneously, the upgrading of equipment formed or in batch is quite convenient and simple, thereby effectively solving the problem that power-fail or fiber-cut is difficult to judge after the existing equipment is powered off.

Fig. 2 is the remote real-time monitoring schematic flow sheet that the present invention realizes communication appliance power down warning.
Embodiment
Below with reference to shown in accompanying drawing, the present invention is realized the remote real-time monitoring embodiment and the embodiment of communication appliance power down warning described in detail.
The remote real-time monitoring method of realization communication appliance power down warning of the present invention, main core point is, one special-purpose Embedded Control Channel is set, and reports message, realize that the real-time monitoring of NM server is not equipped with the terminal network element of NM server by a hardware logic treatment circuit; Be well known to those skilled in the art as for technology such as network element, ECC, receipts No Light Alarm and NCP, do not repeat them here.
Terminal network element is directly by the optical fiber opposite end network element that is connected, if terminal network element power down when power supply input power down, just can send to the opposite end network element to the power fail warning message by ECC (Embedded Control Channel) Embedded Control Channel; The opposite end network element is received the No Light Alarm indication if can also detect after receiving this power fail warning message, then can be judged as power loss event; Otherwise can be judged as disconnected fine incident.
The remote real-time monitoring method of this realization power fail warning is used in the communication apparatus of low capacity more, specifically may further comprise the steps, as shown in Figure 2:
Step S200: the power supply input of terminal network element is when power down, the power supply output of using based on this network element also has certain time-delay, in a single day the testing circuit of the power panel of described terminal network element detects supply voltage and is lower than certain preset value, and equipment just continues to send the low pressure warning indication.
Step S202: need not rise to the network element control processor processing, directly send message, make detection of power loss and the troubleshooting response speed is fast, reliability is high by hardware detection and optical fiber.
Step S204: open up a private byte passage, do not use the overhead byte passage, transmit passage as the power fail warning byte such as what reserve in SDH (Synchronous DigitalHierarchy) SDH (Synchronous Digital Hierarchy).By this designated lane, network element power fail warning message is sent to downstream network element.
Step S206:, be set to the power fail warning message that certain pre-defines in case terminal network element hardware detection to this power down indication, then mails to this overhead byte of all downstream network element.
Step S208: and downstream network element this specific overhead byte by opening up in the ECC passage of receiving detects the power fail warning message that pre-defines for certain, then reports this network element power fail warning to give NM server.
In order to guarantee reliability, downstream network element can adopt repeated detection to then reporting mode, especially can adopt continuous several times to detect the mode that then reports, and detects the mode that reports such as continuous 3 frame checks.
