And listing the influenced communication equipment and a fault conclusion thereof according to the fault conditions of the communication equipment which is influenced by power supply, has power supply interruption and power supply reliability reduction and is obtained by analyzing the fault of the power supply equipment in the analysis process.
The fault state of a communication device depends on the power supply state of its power supply path.
According to the situation that whether the power supply path of the communication equipment is interrupted or not is analyzed, the fault state of the communication equipment can be analyzed, and the following three situations are divided:
a) when all power supply paths are in normal power supply, the power supply of the communication equipment is normal;
b) when all power supply paths are interrupted, the power supply of the communication equipment is interrupted (when all relevant relay sections and channel routes (nodes) borne by the communication equipment are interrupted);
c) the power supply reliability of the communication equipment is reduced when the partial power supply path is in normal power supply and the partial power supply path is in interruption and the power supply path in normal power supply comprises a power supply path which is not supplied by a storage battery; if only the storage battery pack is left to supply power, the conclusion is that: "power supply reliability is reduced, power supply is interrupted for a limited time (battery pack power supply)".
Specifically, the following are mentioned: because the cross board card has a decisive role in the service borne by the network element, for the network element of a plurality of machine frames, if the power supply of the machine frame bearing the cross board card of the network element is interrupted, all channel services of the whole network element are affected, and the fault condition of the channel services is equal to the power supply interruption of all machine frames of the whole network element.
The fault conclusion varies according to the severity of the fault grade, starting with 1 as the highest grade fault and then sequentially with 2, 3 and …. And in the conclusion list, the conclusion with the highest grade is taken as the conclusion display of the fault conclusion.
And analyzing the entity object analysis result contained in the fault equipment according to the equipment type of the fault point. The "name", "type", "analysis conclusion" of the entity object are listed.
And analyzing the optical path analysis result influenced by the fault equipment. The serial number, the fiber core model, the service information, the associated transmission segment name, the fault condition and the analysis conclusion of the light path are listed.
The content includes a channel name, a channel composition, a fault conclusion and a power supply influence conclusion of the hybrid channel, and each value is according to the name of the optical circuit hybrid channel carried by the power supply influenced device. The content of the channel composition is the light, circuit channel name + light/circuit type composing the mixed channel.
The properties and "fault conclusions" of the affected transmission circuit are shown.
The content is the attributes of the affected 64K circuit and the 'failure conclusion', and the analysis condition is the same as the 'transmission circuit' analysis condition.
The display contents are 'belonged network plane', 'channel', 'relay section', 'bandwidth' and 'failure conclusion' and 'power supply influence conclusion'.
Wherein, the value of the network plane is the network plane to which the relay link belongs; "channel" is taken as the channel name associated with the hop;
the "failure conclusion" is that there are both point-of-failure affected and power-affected failures.
The situation in which the fault point affects:
the "failure conclusion" value is consistent with the channel analysis conclusion associated with the relay link.
The conclusion of the fault affected by power supply is mainly divided into three conditions:
a) the device with "power interruption" has a "power interruption" hop conclusion to which it is connected (the "power reliability reduction" device is not listed in the conclusion list as considering not to affect the hop state);
b) when the hop is only affected by the associated channel, if the associated channel is interrupted, the analysis conclusion of the hop is "hop interruption"; if the associated channel single-side route is interrupted, the analysis conclusion of the relay segment is that the relay segment backup protection route is interrupted.
c) If the relay segment has a and b situations, the analysis conclusion gives the conclusion of 'relay segment interruption' according to the processing mode of a. Meanwhile, the relay data in the situation is only displayed once, and the conclusion influenced by the associated channel does not need to be presented.
