Several transmission containers (T-CONT) are assigned to each user. Each T-CONT has an associated GEM port and each GEM port has a VLAN
identifier and an 802.1p priority level.
The ONT classifies the traffic depending on the VLAN and the marked priority, and routes it over the corresponding T-CONT/GEM port. Thus for
frame multiplexing, GEM and T-CONT ports are used for uplink while the downlink only use the GEM ports feature.
ONT7-RGW 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 ONT, as well as for some
aspects of ONT management.
Figure 2-7: 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 Configura-
tion Server) using TR-069 CPE WAN Management Protocol.
