S22, ONU are received after capability set query messages, and current capability set information is reported to OLT；
S23, OLT receive the current capability set information of ONU, according to the current capability set information of ONU, successively under the ONU
The parameter query message for sending out parameter all；
S24, ONU respond OLT parameter query message successively, and the parameter value of current all parameters is reported into OLT.
The ONU parameter values reported and the OLT configuration parameter to be issued being locally stored are compared by S25, OLT, will not
Consistent configuration parameter is handed down to ONU；
After the completion of S26, ONU configuration, confirmation message is sent to OLT.
Between OLT and ONU can using extension OAM (Operation, Administration＆Maintenance operation,
Management and maintenance) ONU is managed for configuration as management medium.Extend shown in the action type table 1 that OAM is supported：
Table 1
During a certain parameters of single query ONU, OLT can issue inquiry frame (Extended Variable Request), that is, lead to
The Extended Variable Request crossed in extension OAM issue parameter query message to ONU；After the completion of inquiry, ONU will
As a result OLT (Extended Variable Response) is returned to, i.e., by extending the Extended Variable in OAM
The current parameter value that Response is reported.
During a certain parameter of single setting ONU, OLT can issue configuration frame (Set Request), i.e., by extending in OAM
Set Request issue configuration parameter to ONU, after the completion of ONU configurations, can be returned by extending the Set Response in OAM
Confirmation；
Fig. 3 is a kind of schematic diagram of optical line terminal of the embodiment of the present invention, refer to Fig. 3：
A kind of optical line terminal, including acquisition module 31 and module 32 is issued, wherein, acquisition module 31 is used to obtain each light
The current capability set information of NE；Issue module 32 current for each optical network unit got according to acquisition module 31
Capability set information, matching somebody with somebody for the capability set information match current with each optical network unit is selected from configuration parameter to be issued
Put parameter and be handed down to each optical network unit.
