2.1 Summary
The FiberGateway is an Optical Terminal Equipment (ONT) unit for Passive Optical Networks (PON)
termination in a FTTH (Fiber-To-The-Home) service delivery architecture. FiberGateway communicates
with the OLT (Optical Line Terminal) for the PON side and with the customer’s premises for the client
side. This equipment supports triple-play services - high speed internet (HSI), voice (VoIP), video (IPTV)
and WPS (WI-FI Protected Setup). The use of the GPON fiber access technology does allow a
significant service delivery increase when compared with traditional xDSL technologies.
The FiberGateway equipment technology is based on GEM (GPON Encapsulation Method), and
complies with ITU-T G.984.x. recommendation as like as G.984.4 (OMCI) ensuring interoperability with
major GPON OLT vendors.
These base functionalities, together with the support for bit rates of up to 2.5 Gbps (downstream) and
1.24 Gbps (upstream), an optical network splitting ratio of up to 1:64 in a single fiber and a distance
range of up to 60 km, make the GPON technology and the FiberGateway the most efficient option for
passive optical network topologies, when integrated service delivery is an issue.
Together with multi-vendor OLT interoperability, other differentiated features of the FiberGateway
product include the use of an embedded optical reflective component that increases probing resolution
in case of FTTH probing. The FiberGateway is also one of the first single household integrated CPE
solution (ONT+GATEWAY).
As opposed to the point-to-point architecture, in which there is one physical port per client in the
Central Office, in GPON point-to-multipoint architecture there is only a single laser and photo-detector
in the Central Office (CO) to serve up to 128 CPEs. All the Optical Distribution Network is built by means
of passive equipment modules with a long live MTBF standards and very low OPEX
2.2 Technical Description
2.2.1 FiberGateway Main Functionalities
The FiberGateway is aimed for customer premises and complies with the ITU-T G.984.x
recommendation in order to transport (over GPON) and deliver (to premises domain) the full broadband
service pack.
Broadband service applications are commonly referred as below:
• High speed internet (HSI);
• Voice (VoIP) services (SIP/MEGACO H.248);
• TV (IPTV);
• WI-FI.
The multiplay environment is thus reinforced when combining the upper referred services.

2.2.2 FiberGateway Application Scenario
The next figure shows a possible gateway scenario for FiberGateway equipments when in an FTTx
architecture.
Figure 1: FTTx architecture
2.2.3 Interoperability
FiberGateway equipment complies with ITU-T G.984.x. recommendation as like as G.984.4 (OMCI)
ensuring multi-vendor OLT interoperability with major GPON OLT vendors, as defined in BBF.247 ONU
certification program.
BBF.247 ONU certification program certifies ONT link layer Configuration and management protocol,
OMCI, as defined by ITU-T G.984.3, ITU-T G.984.4 and ITU-T G.988.

FiberGateway
Figure 2: Link Layer Configuration and Management
IP-based services Configuration and management is achieved by means of the TR-069 protocol as
defined by Broadband Forum. This procedure takes for granted that previously the link layer connectivity
has been achieved.
TR-069 is then transparent to the OLT, since the TR-069 connections are established between the ACS
and the ONTs.
ONT gateway family equipments integrate gateway functionalities. Link layer Configuration and
management is achieved by the use of OMCI, while IP-based services (RG functionality and Voice over
IP) are configured and managed by TR-069.

2.3 General Features
GPON is a point-to-multipoint passive optical network, in which unpowered optical splitters are used to
enable a single optical fiber to serve multiple premises, typically 1-64.
A PON consists of an optical line terminal (OLT) at the central office and a number of optical network
terminals (ONT) at the customer premises. Downstream signals are broadcasted to all premises sharing
multiple fibers. Encryption can prevent eavesdropping. Upstream signals are combined using a multiple

access protocol (Time Division Multiple Access - TDMA). The OLT queues data to the various ONT
terminals in order to provide time slot assignments for upstream communication.
In Figure 5 it is shown a scenario for a multi-service user domain basic architecture through an ISP.
Figure 5: Optical fiber Internet service user access
In the upstream direction, the FiberGateway is connected to the optical splitter and respectively to the
OLT through the PON port to provide integrated access services through the service headend.
In the downstream direction, the FiberGateway is connected to various terminals through the following
LAN-side ports to implement multi-play services:
• Four 10/100/1000M Base-T Ethernet ports, which can be connected to terminals such as PCs,
STBs, and video phones to provide the high-speed data and video services;
• One FXS ports, which can be connected to telephone sets to provide VoIP services;
• Four Wi-Fi antennas, which can connect to Wi-Fi terminals wirelessly to provide a secure and
reliable high-speed wireless network;
• One USB port, which can be connected to a USB storage device to provide convenient storage
and file sharing services within a home network;
The communication between client equipment (ONT) and the ISP access routers (MAN edge) is made
by an optical fiber-based passive architecture (ITU-T G.984 Recommendation). The GPON network acts
as a Layer 2 Ethernet metropolitan network. Access network assures and controls the media (MAC)
communication through a TDMA scheme, introducing GEM (GPON Encapsulation Method) in between
to adapt TDM layer to Ethernet.
The used protocol stack is shown in next figure

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.
