In an EPON OLT system, such functional differentiation is generally implemented in communications interaction of oam (operation Administration and maintenance). The general approaches are divided into two categories:
one is to use the MODEL ID and the VENTOR ID as basic classification means according to the basic information reported by the ONU, i.e. the software and hardware version number corresponding to the OLT manufacturer format, and if the version number in the information reported by the ONU does not accord with the format required by the butted OLT, the priority and even the basic service and the like are influenced when the OLT processes the service of the ONU.

when the OLT of different manufacturers in the product use area is more, the identification is started, and if the OLT type of the manufacturer is not the OLT of a single manufacturer, the strict identification is selected. The strict identification implementation steps are as follows:
after the EPON system completes the expanded OAM discovery process, in the process of OAM keep-alive processing, the OUI value of the heartbeat packet is judged to be consistent with the OUI value of China telecom or the OUI value of a manufacturer by taking the unique identification OUI value of a mechanism in the heartbeat packet as a judgment standard.
If the OUI value of the heartbeat packet is consistent with the OUI value 0x111111 of the chinese telecom, the relevant step of not starting the identification is executed, specifically as shown in embodiment two, that is, the current reporting value is read from the identification variable a of the flash, and it is determined whether the current reporting value is consistent with the default reporting value B1. If the current reported value is consistent with the default reported value, completing all processes of the method that the ONU is suitable for different OLTs; if the current reporting value is inconsistent with the default reporting value, the default reporting value stored in B1 is read, the default reporting value is overwritten on the current reporting value, the current reporting value is changed into the default reporting value, and the system calls a self-contained function to restart after the current reporting value is changed into the default reporting value.

If the OUI value of the heartbeat packet is consistent with the stored manufacturer OUI value, the following steps are further included between step S3 and step S4.
If the factory-specific OUI value matches the factory OUI value stored in the reported information variable, the relevant steps of ordinary identification are executed, as specifically shown in the third embodiment.
And if the factory-dedicated OUI value is not matched with the factory OUI value stored in the reported information variable, executing the relevant step of not starting identification.
Example three:
the strict identification mode as shown in the second embodiment is more accurate in specific implementation, but the failure rate is higher, if the OLT type of the product use area is the OLT of a single manufacturer, the general identification is started, and the specific steps of the general identification are as follows:
after the common identification entry is authenticated, in the process of extended attribute management and operation, the source MAC address of a CTC packet of OAM is taken as a judgment basis, the MAC address of the CTC packet is compared with a factory MAC address pre-stored by a flash, and whether the first three bytes of the MAC address of the CTC packet are consistent with the prefix of the factory MAC address is judged:

Recording all the branches and leaves interacted in the OAM negotiation process, reading the matched branch and leaf values of the information variables reported by the corresponding manufacturers in the flash, and comparing one by one.
If the branch and the leaf of the interactive private protocol and the branch and the leaf of the private protocol in the extended OAM management of the factory OLT have corresponding values, the checking result is passed, the current reported value is checked, and whether the current reported value is consistent with the corresponding factory OLT reported value is judged.
Preferably, if the current reported value is consistent with the value reported by the manufacturer OLT, the whole process of the method of adapting the ONU to different OLTs is completed; and if the current reported value is inconsistent with the value reported by the manufacturer OLT, changing the current reported value into the corresponding value reported by the manufacturer OLT, and restarting the system.
If the branch and the leaf of the interactive private protocol and the branch and the leaf of the private protocol in the extended OAM management of the factory OLT do not have corresponding values, that is, the OAM interaction does not have the unique branch and leaf of the corresponding factory, the verification fails, and the step related to the un-activated identification is executed, which is specifically shown in embodiment two.
If the first three bytes of the MAC address of the CTC packet are inconsistent with the MAC address prefix, that is, the MAC address of the CTC packet cannot be matched with the MAC address pre-stored in the flash, the identification cannot be performed, and the relevant steps of not starting the identification are executed, as specifically shown in embodiment two.
