a small-cell base station through GUI pre-deployment in the scenario with the U2000 NMS
available.
14.4.9.1 Service Requirements and Application Scenarios
Service Requirements
As the last mile that connects users to the Internet, small-cell backhaul is an important part of
an FTTx network. For small-cell backhaul, customers expect to:
l
Make full use of the existing access resources to provide backhaul services for distributed
small-cell base stations.
l
Use a simple and mature service configuration scheme, featuring a high transmission
efficiency in addition to ensuring the QoS.
l
Simplify sites to lower the site installation and maintenance costs.
Application Scenarios
, ONUs, functioning as Dock devices, receive Ethernet service data
from small-cell base stations through Ethernet ports and then send the service data to the OLT.
The OLT restores the Ethernet signals and adds 2 VLAN tags (QinQ VLAN encapsulation) to
the data, so that the data from the small cell bases can be transparently transmitted to the peer
PTN devices through the public network and then the PTN devices restore them to the original
data.
ONU applicable to this scenario: MA5694S
