Technical Description
Q_PPS_DM_018_V1.3
The XG_PON Fiber Gateway classifies the traffic depending on the VLAN and the marked priority, and
routes it over the corresponding T-CONT/XGEM port. Thus for frame multiplexing, XGEM and T-CONT
ports are used for uplink while the downlink only use the XGEM ports feature.
XGS-PON Fiber Gateway equipment complies with Broadband Forum TR-142 Technical Report, which
defines a framework for the remote configuration and management of IP-based services over PON
(Passive Optical Network) and fiber access technology.
TR-142 framework uses TR-069 which is the protocol of choice for the remote management and
configuration of IP services over PON and fiber access networks. TR-069 is intended to be used for the
remote configuration and management of IP services running over XGS-PON Fiber Gateway
(ONU/ONT) , as well as for some aspects of its management.
Figure 7: TR-142 Framework
TR-142 framework defines a virtual UNI between the OMCI (ONT Management Control Interface) and
TR-069 management domains.
This framework allows PON CPE with L3 layer capabilities to be mass remotely configured, troubleshoot
and managed by an ACS (Auto Configuration Server) using TR-069 CPE WAN Management Protocol.
