13.3.3 Enterprise IP PBX Private Line Access Service
ONUs provide GE/FE ports to access IP private branch exchange (PBX) services of an enterprise
and transmit them to an OLT. Then, the OLT forwards the service data upstream to the packet
switched network (PSN). This achieves unified carrying of voice, data, and video services.
13.3.3.1 Service Requirement and Application Scenario
Service Requirement
l
The IP private branch exchange (PBX) data can be transparently transmitted on the PON
network.
l
The operation method for end users connected to the IP PBX is not changed.
Application Scenario
, ONUs access IP PBX services through FE/GE ports. The OLT
transparently transmits the data to the IP network in QinQ mode.
Applicable ONUs: MA5612, MA5628, MA5616
