Embodiment Construction
[0026] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0027] figure 1 Be the flow chart of the present invention, as figure 1 Shown, the present invention comprises the following steps:
[0028] S10. After the LCT is connected to the network element device, it repeatedly sends the request access data packet to the network element management unit of the network element device. The data packet requesting access includes: sending command code, address parameter of the network element equipment accessed by the LCT, time parameter of the LCT access and connection status identifier, and the network element management unit judges the data packet currently received according to the sending command code Whether it is a request access data packet sent by the LCT, and whether the data packet complies with the application layer transmission communication protocol of the LCT and the network element management unit. The connecti...

The invention discloses a method for remotely monitoring a local maintenance terminal, comprising the following steps of: after S10 and LCT are connected with network element equipment, continuously and repeatedly sending request accessing data packets; obtaining a judging result of the successful connection or the disconnection of the LCT by taking the number of the request accessing data packets sent by the LCT and received by S20 and a network element management unit within a preset time as a judging condition; and updating logs according to the judging result by S30 and EMS. The inventionsolves the problem that LCT access operation can not be monitored and LCT log logging can not be recorded in the EMS in the prior art, is favorable to realizing the centralization and the automated management of LCT monitoring, changes the current situation that the traditional network management system can only manually process the LCT access authority of multiple network elements and is favorable for privileged users to start an LCT access function under a condition that the network elements are separated from the monitoring of the EMS in such a way that a forbidden port is opened by codes,thereby being convenient for the maintaining work of network managers.
Description
technical field [0001] The invention relates to an optical transmission system, in particular to a method for remotely monitoring a local maintenance terminal. Background technique [0002] The technical terms adopted in the present invention are explained as follows: [0003] NE, network element equipment; [0004] EMU, network element management unit; [0005] LCT, Local Craft Terminal, local maintenance terminal; [0006] EMS, Element Management System, network element management system; [0007] ECC: Embedded Control Channel is embedded in the control channel. ECC in the SDH network is a logical channel for transmitting operation, management and maintenance (OAMP) information. [0008] In an optical transmission system, LCT is an important part of system maintenance and management. It mainly provides auxiliary functions such as online or offline modification of system configuration data, current or historical alarm viewing, real-time performance statistics, and vario...
