The present invention relates to a maintenance and operation management method between any transmission equipment at a remote location when constructing a transmission network.

Asynchronous transmitters (45Mbps, 565Nbps class transmitters, etc.) currently installed and operated in the field transmit and receive maintenance data using data communication channels between opposite transmission terminals, and mutually recognize types of data transmitted and received. It has been prescribed in the form that can be.

Therefore, the form and meaning of the transmission and reception data can be mutually recognized only between the transmission apparatuses facing each other, and the form and meaning of the maintenance data can be recognized in the case of different types of transmission apparatuses or even if they are the same type. There is a problem that the maintenance is complicated and inefficient, and the cost of maintenance and operation management is increased because it is impossible to do, and thus consistent maintenance and operation is impossible.

In order to solve the above problems, the present invention performs consistent maintenance and operation regardless of the type or manufacturer of a transmission device when constructing a transmission network to efficiently perform maintenance and operation of the transmission device and improve the performance of the entire transmission network. Its purpose is to provide a maintenance and operation management method that can improve and reduce maintenance and operation costs.

In order to achieve the above object, the present invention is applied to a transmission device comprising a remote registration system and a remote registration system, wherein the remote registration system receives a start command and a password from an operator to the remote registration system. A first step of delivering a right of use priority and a start message; After performing the first step, the remote registration system transmits an operation menu to the remote registration system when the passwords match and the priority is lower than the priority of the remote registration system. A second step of transmitting a message to the remote registration system that the password and the priority are not appropriate; After performing the second step, when receiving a message from the remote registration system that the password and priority is not appropriate, it detects that the session is not established, and receives a menu from the remote registration system from the operator Determining whether an end command is input; After performing the third step, if the end command is not received from the operator, the remote system transmits a control key of an operation menu to the remote system, and receives a control key from the remote system to recall the operation menu according to the control key. A fourth step of transmitting to a remote system; After performing the third step, when the remote registration system receives a termination command from the operator, the remote registration service is terminated by transmitting a termination message to the remote registration system and receiving the termination message at the remote registration system. Characterized in that it comprises a step.

Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment according to the present invention.

Since the conventional maintenance method between transmission devices is based on the type and meaning of the message, message compatibility problems between the transmission devices are raised, and the maintenance and operation management of heterogeneous transmission devices is not possible in principle.

The present invention maintains and operates irrespective of the message type and meaning of the system by accessing a specific system to be maintained and operated remotely without registering the meaning of mutually transmitted / received messages and remotely registering as an operator of the system. To allow management to be performed. In other words, by using the data communication channel of the remote system, the menu for the man machine interface (hereinafter referred to as MMI), which is an interface between the environment and the system and the user for the maintenance and operation management of the remote site, is displayed on the operation terminal in the home country. Although geographically different, it is possible to perform all maintenance and operations management operations as if it were an operating terminal directly connected to a remote system.

The present invention has a different procedure and protocol than the remote registration method used in the UNIX system. Unlike the remote registration of the UNIX system, which can be accessed by multiple users at the same time and using the Transmission Control Ptotocol and Internet Protocol (TCP / IP) communication protocol using a local area network (LAN), the remote registration of the present invention uses the SDH data. Using the communication channel (hereinafter referred to as DCC) protocol, the remote registration procedure was simply configured.

Remote registration function of SDH transmitter is a function that can operate SDH transmitter in remote system to local system in synchronous multi-system sub network environment. In other words, it refers to a function that can directly perform MMI operation of a remote system in a local system regardless of whether an operator of a remote system exists.

In principle, the remote registration function accesses any remote system through the system identifier and the password of the system in a sub-network environment composed of synchronous multi-systems, and checks the current system configuration status, failure status, and performance information of the system. You can inquire.

1 is a block diagram of a device to which the present invention is applied, and the remote registration of the present invention uses a DCC channel, which is a maintenance channel of the SDH transmission device, and the DCC channel is the International Telecommunication Union (ITU-T) G.784. According to the recommendation, the protocol of data link layer is LAPD (Link Access Procedure on the D-channel), the network layer protocol is ISO 8473, and the maximum data size of input command and response transmitted / received during remote registration function is ISO 8473 which is network layer. Follow the maximum data transfer capacity of.

The remote registration of the present invention handles the function of sending a remote registration message to any system as long as each synchronous multiple device has a unique device address in a subnetwork environment composed of synchronous multiple devices. The device address is checked by the network layer. If the device address is not correct, the packet is copied to all ports except the input port or the routing table is referred to and transmitted to the corresponding port.

2 is a block diagram of a transmission / reception message during a remote registration session, which has a total data length area and a data area, and has a total data length of 2 bytes.

3 is a block diagram of a message at the start of remote registration, which includes a total length of 2 bytes of data, a 1 byte of Control X (control means a control key of a keyboard), a priority field of 1 byte of use, and It has a password field of 10 bytes.

4 is a block diagram of a message at the end of remote registration and has a total length area of 2 bytes and a control queue area of 1 byte.

5 is a flowchart according to the present invention.

The start of the remote registration service of the present invention is started by inputting a start command 'Control X' on the main menu of the remote registration system (the system which attempts the remote registration) (1). The remote registration system, which has received the key, receives the password (2) and transmits the message of FIG. 3 together with the right of priority to the remote registration system (the system to be remotely registered) (3).

In the remote registration system receiving the message of FIG. 3 (10), the password is checked and the same (11) and the priority is lower than the priority of the remote registration system (12) system maintenance and operation management of the remote registration system. The menu is sent to the remote system (14). In this case, if the password and priority are not appropriate, the remote system transmits a message that the password and priority are not appropriate (13), and the remote system detects that the session is not established with the corresponding message (5).

Therefore, if the remote registration is successful, the remote registration display appears in the MMI menu of the remote registration system, and the remote system indicates that the local system is remotely registered when the first keyboard input is processed after the remote registration. If the remote system receives the menu from the remote system (4) and does not receive the control command (Control Q) from the keyboard (6), it transmits the control key of the menu to the remote system (7). The system receives a control key (16) and transmits a menu corresponding to the control key (14) for remote registration service.

In this state, access to the MMI operation change menu of the remote registration system and the remote registration system is made exclusively on one side according to the right of use priority.

The MMI screen of the system that attempted the remote registration during the remote registration session shows the operating status of the remote system, and the system that has been remotely registered shows the normal operating status of the local station, except that the operation change of the local station can be restricted according to the operating right. . In both system MMI main menus, only accessible menus are displayed in bold according to the priority negotiation result.

The termination of the remote registration service is terminated by entering a 'Control Q' on the main menu of the remote system. That is, the remote system receives the 'control queue' from the keyboard (6) by sending a message of FIG. 4 to the remote system (8) by receiving a message of FIG. 4 from the remote system (15) and the remote registration service ends. (9) Termination of remote registration service is done regardless of permission of remote system.

The usage right priority used in setting up a remote registration session as described above enables to limit the use of all operation management functions of the remote registration remote system in order to maintain the consistency of system operation and smooth system management. That is, operation commands that affect the state of the system, such as system configuration change or parameter change, are possible only by the system operator having a higher priority in operation management.

In general, there is no restriction when the operator in the local system operates the local system, but in the remote registration situation, it is limited by the priority of the operating rights between the two system operators. In other words, when the priority of the system that attempts remote registration is high, all operation modes of the remote registration system can be accessed, while the operation change of the local system is restricted during the remote registration session. That is, during the remote registration session, the local system can only query the operating status of the own station, even if it is its own system. On the other hand, when the priority of the system attempting remote registration is low, only the operating status of the remote system can be inquired, and the operation of the local system is not affected at all.

The remote registration of the present invention eliminates the confusion of operation by preventing new remote registration service of both systems when any system attempts or provides a remote registration service. As a result, in the synchronous multi-device subnetwork, remote registration can be connected to any one system, so that when N (N is a natural number) systems exist, up to N / 2 remote registration connections can be made at any time.

In order to make the operation of the above system consistent, all synchronous systems can change the operation mode of the local system or change the system configuration by themselves, but if they are remotely registered by a system with a higher priority of operation than the local system, remote registration During the session, it is not allowed to change the system configuration or parameters in the local station, but only to view the status information of the local system.

The present invention as described above can also be used in an asynchronous transmission device having independent operation and maintenance channels.

The present invention as described above has the effect of controlling the operation mode by remote registration of the remote system, monitor the system status and maintain the consistency of the system operation of the sub-network.
