Often, exclude because remote network element caused by access network element failure manages failure；
Step 303, the physical connection between access network element and non-access network element is checked, optical fiber is checked usually using instrument
Transmitting-receiving luminous power whether there is failure.
After webmaster, access network element and physical connection failure is excluded, using the example of the present invention come maintenance of far end network element：
Step 304, whether remote network element is judged because two or three layers of attribute abnormal or network element IP attribute abnormal cause de- pipe, such as
Fruit is to go to step 305, otherwise goes to step 306.
Privately owned common message is sent using DCN monitor channels, privately owned message so that Ethernet is encapsulated as an example, be shown in by specific form
Fig. 4.
Two or three layers of attribute of remote network element, including remote network element Port IP, subnet mask, MAC are inquired about by the message
Location, connection type (PPP/ETH), VlanID and bandwidth information etc., inquire about the network element IP attribute of remote network element, including remote network element
The information such as IP, subnet mask, MAC Address.And by configuration information compared with Network planning information, it is confirmed whether have exception to match somebody with somebody confidence
Breath.
Step 305, then privately owned message is issued still with DCN monitor channels, configuration information is changed according to the network planning,
Solves failure.
Step 306, two or three layers of attribute of remote network element are normal.Continue through DCN monitor channels queries static route, OSPF
The information such as region, whether have abnormal information, if it is step 307 if judging the other configurations information of network element.
Step 307, remote network element causes de- pipe due to information such as network element static routing, ospf areas, then is supervised using DCN
Passage sending configuration message is controlled, configuration information is changed according to the network planning, solves failure.
Step 308, if above-mentioned configuration information is no abnormal, remote network element is inquired about by DCN monitor channels and closed
Key warning information, the abort situation and failure cause of remote network element are confirmed according to crucial warning information.
Step 309, if it is possible to guilty culprit veneer, and fault-free solution are determined, can be by under DCN monitor channels
The power down of bill plate, reset command, by failing single board power down, reset.
Step 310, after pending fault board resetting is restarted normally, check whether failure solves again through DCN monitor channels,
Common service exception and de- pipe failure can be released by power down, reset, and remote network element can be by NE management device normal pipe
Reason.

The specified veneer of network element.
In one embodiment, in addition to：
Encapsulation unit, for by the first privately owned common message, the second privately owned common message, the 3rd privately owned common message, the
One privately owned configuration message, the second privately owned configuration message and the 3rd privately owned configuration message encapsulate to form message with Ethernet.
The present invention provide it is a kind of monitor remote network element system, as shown in figure 5, including access network element A, non-access network element B,
Monitor the NE management device of remote network element；
Electrically connected between access network element A and non-access network element B by fiber optic links, NE management device with access network element A.
In embodiment, as shown in figure 1, access network element is the network element being directly connected with NE management device, non-access network element
Be then refer to access network element direct or indirect connection, and by access network element by the network element of NE management device management.
To solve the de- tube apparatus fault location in distal end, NE management device manages the non-access of distal end by access network element A
Network element B, when non-access network element B is due to the process of the management, the then non-access network element B of maintenance of far end of certain failure disengaging network management system
The embodiment described in accompanying drawing 3 is may be referred to, including：
Step 501, check whether server client-NE management device of Element management system is working properly, side by side
Except the de- pipe of non-access network element caused by access network element failure, specific method includes：Check routing iinformation, the veneer work of access network element
Make state and alarm clearing situation；With instrument detect access network element A and non-access network element B between optical fiber transceiving luminous power whether
Normally.
Step 502, after excluding NE management plant failure, access network element failure and physical connection failure, monitored by DCN
Passage sends privately owned common message to non-access network element B, and checking non-access network element B two or three layers of attribute is：
Optical port IP：50.50.50.160
Optical port mask：255.255.255.0
Optical port MAC：0011-5a5a-4bc8
Optical port connection type：PPP
Non-access network element B two or three layers of attribute and networking planning are contrasted, with reference to access network element A two or three layers of attribute：
Optical port IP：50.50.50.121
Optical port mask：255.255.255.0
Optical port MAC：0011-1cd2-144c
Optical port connection type：eth
Positioning contrast finds that the connection type at two interconnection critical points is inconsistent.Configuration modification is issued by DCN monitor channels
Message, non-access network element B optical port connection types are revised as eth types.
Step 503, privately owned common message is sent to non-access network element B by DCN monitor channels, checks non-access network element B
The attribute such as network element IP it is as follows：
Network element IP：192.43.43.43
Network element IP mask：255.255.255.255
Network element MAC：0011-2198-f54d
Network element ospf area：2.0.0.0
The network element attribute of non-access network element and networking planning are contrasted, with reference to access network element A network element attribute：
Network element IP：192.12.12.12
Network element IP mask：255.255.255.255
Network element MAC:0011-8f97-4545
Network element ospf area：0.0.0.0
Positioning contrast finds that non-access network element B and access network element A network element ospf area number configuration is inconsistent, passes through DCN
Monitor channel issues configuration modification message, and non-access network element B network element ospf area number is revised as into 0.0.0.0.
Step 504, privately owned common message is sent to non-access network element B by DCN monitor channels, checks non-access network element B
On warning information.The plate abnormal information of veneer where optical port used in non-access network element B monitoring is included in warning information.Due to non-
Access network element B regions and NE management device region can not navigate to the specific abnormal cause of veneer apart from remote,
But the failure can be released by plugging veneer.
Step 505, privately owned common message is sent to non-access network element B by DCN monitor channels, by non-access network element B's
Abnormal single-board carries out power down, resets operation.Board resetting is abnormal after restarting to be released, and NE management device can be with normal management net
Member.
It is using the advantage after this programme：Using the DCN monitor channels of POTN equipment, the two of the de- pipe network member in distal end is transmitted
Three layers of attribute, network element configuration information and crucial warning information, and master control borad, business board can be carried out by remote maintenance order
Power down, reset etc. operate, and are finally reached maintenance of far end network element, solve the purpose of failure；Improve the de- pipe network member in distal end safeguard into
This, improves the efficiency of fault location solution, to reach reduction fault location cost, put forward efficient purpose.
Described above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, on the premise of principle of the present invention is not departed from, some improvements and modifications can also be made, these improvements and modifications
It should be regarded as protection scope of the present invention.
