Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an SDH (Synchronous
ous Digital Hierachy)
Regarding the path registration processing method in the transmission terminal equipment,
The present invention relates to a path registration processing method in a network management system constituted by DH transmission terminal devices.

[0002]

2. Description of the Related Art Synchronous digital hierarchy (hereinafter referred to as "S
DH) means an international standard high-speed relay speed system, and digital hierarchy means, for example, for efficient transmission, a subscriber line is first digitally multiplexed into a local line and then multiplexed. Is a rule of the transmission speed of each stage that is multiplexed in stages, such as transmission over long distances.

[0003] Conventionally, in a network constituted by SDH transmission terminal devices (hereinafter referred to as "new synchronous terminal devices"), when an optical cable is newly laid between the new synchronous terminal devices, or when a new synchronous terminal device is used. When a path between the new synchronous terminal equipments is newly established by the cross-connect connection within the network, the network controller performs path registration control for the new synchronous terminal equipment and further confirms signal communication. Therefore, a quality measurement test is performed using a tester.

[0004]

However, in the path registration processing when an optical cable is newly laid between the network devices constituted by the new synchronous terminal equipment, the problem is an input error or a connection error at the time of path registration. Such an artificial connection error cannot be detected at the time of path registration, and is detected only after moving to the quality measurement service later.If there is a path connection error, the path must be opened again after the quality measurement service. It is necessary to do so, and the operation efficiency is inferior.

[0005] The reason for this is that when a new path is laid,
This is because whether or not the path is mounted on the interface board and the type of the package mounted on the interface board are determined only, and signal communication between the opposing new synchronous terminal devices is not checked. That is, this signal communication confirmation is first confirmed between the opposing new synchronous terminal devices by a drop / insert test of a test signal by a built-in tester or an external tester.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above problems, and a new path is established between new synchronous terminal apparatuses in a network constituted by SDH transmission terminal apparatuses (new synchronous terminal apparatuses). It is an object of the present invention to provide a path registration processing method in an SDH transmission terminal apparatus that enables signal communication confirmation when registering a new path along with the installation and achieves more efficient operation.

Next, the operation of the path registration processing in the path registration processing method in the SDH transmission terminal equipment according to one embodiment of the present invention will be described.

Referring to FIG. 1, in a path registration processing method in an SDH transmission terminal according to an embodiment of the present invention, a new synchronous multiplexing device 1a, which is an SDH transmission terminal, is used.
When three paths 2a, 2b, 2c are newly established between 1b,
After laying the cable including the paths 2a, 2b and 2c, the path registration control means 3b of the network control device 3 sends a path registration command to the new synchronous multiplexing devices 1a and 1b facing each other. First, a path registration command is sent to one of the new synchronous multiplexers 1a.

The new synchronous multiplexing device 1a, having received the path registration command, uses its path authentication number generating / managing means to
After confirming that the path authentication number has not been received from the opposite new synchronous multiplexing device 1b, the date and time information is read from the time device 4a, and the read date and time and the path authentication of the newly established paths 2a, 2b, 2c. Generate and manage as numbers. In the example shown in FIG. 1, the authentication number of the path 2a is “12150005” and the authentication number of the path 2b is “12150005”.
0030 "and the authentication number of the path 2c is" 12150050 ".

The new synchronous multiplexing device 1a returns these generated path authentication numbers to the path authentication number collating means 3a as a command response to the path registration command, and the path authentication number transmitting means transmits the path overhead signal (path). The path authentication number is transmitted to the opposing new synchronous multiplexing device 1b using the operation information area of the frame. The path authentication numbers transmitted from the new synchronous multiplexing device 1a to the path authentication number matching means 3a of the network control device 3 and the new synchronous multiplexing device 1b are as follows.

Notification of path authentication number from apparatus A: path 2a
Authentication number = “12150005”, the authentication number of path 2b = “12
150030 ", the authentication number of the path 2c =" 12150050 ".

The path registration control means 3b transmits a path registration command to the other new synchronous multiplexing device 1b, similarly to the new synchronous multiplexing device 1a. The new synchronous multiplexing device 1b that has received the path registration command has received the path authentication number from the new synchronous multiplexing device 1a for the corresponding path related to the received path registration command by the path authentication number generating / managing means. Then, the path authentication number transmitted and received from the new synchronous multiplexer 1a is managed as the corresponding path authentication number. The new synchronous multiplexing device 1b compares the managed path authentication number as a command response to the path registration command with the path authentication number matching means 3 of the network control device 3.
Reply to a. However, IDF (interface board)
Since the path 2b and the path 2c are incorrectly connected, the path authentication number managed by the new synchronous multiplexing device 2b and returned to the path authentication number collating means 3a is an incorrect number as follows. .

Notification of path authentication number from new synchronous multiplexing apparatus 1a: authentication number of path 2a = “12150005”, authentication number of path 2b = “12150050”, authentication number of path 2c = “1215”
[0030] That is, the authentication number of the path 2b and the authentication number of the path 2c are interchanged.

The path authentication number checking means 3a of the network control unit 3 checks the path authentication numbers transmitted and received from the two new synchronous multiplexing apparatuses 1a and 1b. Do. If they do not match, the operator is notified of the abnormal end.

Table 1 shows the result of collating the path authentication number in the path authentication number collating means 3a.
