When in PON constructing or safeguard, generally require to understand the specifying information of field network, to keep away
Exempt from operating mistake, at this moment message recipient is accessed the port checked needed for ODN networks, PDA leads to
Cross WIFI, mobile base station or the mode such as wired and access internet, Telnet network management system, in webmaster system
System issues a command to OLT up and down, and OLT is dealt into affiliated identification information on OLT optical modules, such as optical module
I2C interfaces, then by optical module local side light generating apparatus (such as the laser instrument of downstream wavelength, OTDR's
Laser instrument etc.) identification information bag is converted into into optical signal, it is sent on the ODN networks at place.
Message recipient receives the sent out identification information bags of certain OLT from ODN, can according to packet
Topology of all information and place network of OLT, ONU/ONT and ODN etc. is found online or offline.
If being not received by information, network failure is quoted, or not in compass of competency.
OLT identification informations bag can include physics link information and logical connection information, physical connection such as OLT
Website, frame number, slot number and port numbers etc., logical connection information such as VLAN etc..In order to reduce solution
Mistake is separated out, condition code and check code can be increased.
Maintenance port place OLT information, place network topology can quickly be understood using above-mentioned technical proposal
