Technical Description
Figure 6: Stack of protocols for GPON architecture
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.
FiberGateway 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 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.
