14.4.3 Ethernet Base Station Access Service (in QinQ VLAN Mode)

ONUs are connected to IP base stations through FE/GE Ethernet ports and OLTs are
interconnected with MAN equipment in QinQ VLAN mode to achieve access of base station
services.

14.4.3.1 Service Requirement and Application Scenario

Service Requirement

Application Scenario
As shown in
FE/GE ports, encapsulate the ETH packets into GEM frames, and then send them to the OLT
through the GPON upstream ports. The OLT restores the ETH signals and configures QinQ
VLANs for the signals to enable the data of base stations to be transparently transmitted to the
remote PTN over the public network. Then the remote PTN device restores the ETH signals.
Applicable ONUs: MA5612, MA5628, MA5616

ONUs are connected to 3G/LTE base stations and GPON is used for carrying the mobile
access network in a unified manner to meet mobile carriers' requirements for a high
bandwidth and high-density coverage of base stations.
A simple, mature solution is used for service configuration to ensure high service quality
as well as high transmission efficiency.
