A miniaturized potn device and a remote power-off prompting method

Abstract

The invention discloses a miniaturized POTN device and a remote power-off prompting method, and relates to the communication field. The equipment includes two main control cross-connect boards and OTN service boards that are mutually active and standby. The equipment also includes: a message processing module is set in each main control cross-connect board, and is used to receive power-off alarm information from the voltage detection module of this board , to receive the power-down alarm information sent by the message processing module of another main control cross-connect board; when both main control cross-connect boards generate power-down alarm information, the message processing module of the active main control The first power-down prompt message is output to the ETH SWITCH switch chip and then inserted into the ETH service, and the power-down alarm information is sent to the OTN service board at the same time; the overhead processing module is set in the OTN service board to insert the power-down alarm information into The OTN service is then sent to the remote end. The invention can insert the power-down alarm information into the OTN service and send it to the remote end within the energy storage time of the OTN service board.

Description

[0001] The invention relates to the technical field of communication, in particular to a miniaturized POTN device and a remote power-off prompting method. Background technique [0002] POTN (Packet Optical Transport Network, Packet Optical Transport Network) integrates PTN (Packet Transport Network, Packet Transport Network) and OTN (Optical Transport Network, Optical Transport Network) two technologies, which can improve the carrying capacity of the transport network and reduce network costs. With the rapid development of services such as 4G, IPTV, and broadband access, data traffic has grown explosively, and POTN equipment for packet optical transport networks has begun to be used on a large scale. Miniaturized POTN equipment is small in size and capacity, and is mostly used in access nodes and small aggregation nodes. In order to ensure the normal operation of miniaturized POTN equipment, the particularly important main control When the main control cross-connect board fail...

AI Technical Summary

Problems solved by technology

Due to the high port density, high power consumption, and complex design of the main control cross-connect board and OTN service board, the energy storage time of the board card is relatively short due to the limitation of board layout space
