Overview 

z 

With an Ethernet passive optical network (EPON) board, an S7900E switch can operate as the optical 

line terminal (OLT) device of an EPON system and connects to remote optical network unit (ONU) 

devices.  

Extended OAM is mainly used to establish connections between an OLT and its ONU and enable the 

OLT to manage the ONUs remotely.  

New types of OAMPDUs are introduced in extended OAM. By sending these new types of OAMPDUs, 

an OLT and its ONUs can send connection requests and responses, and exchange various 

management information.  

Extended OAM adds an Organization Specific Information TLV to the information OAMPDU. For details 

about information OAMPDUs, refer to Ethernet OAMPDUs. An information OAMPDU containing this 

TLV is called an extended information OAMPDU.  

The Organization Specific Information TLV contains the following contents: 

z 

Local Organizationally Unique Identifier (OUI): Identifies the vendor of the local device.  

z 

Supported OUI addresses: Specifies the vendors whose devices can interoperate with the local 

OLT or ONU device.  

z 

OAM version number: Indicates the version of the OAM protocol used by the local OLT or ONU 

device.  

Organization Specific OAMPDU is a newly added OAMPDU type. It is identified by the 0xFE field, as 

shown in
