Overview

The ONT-RGW is an Optical Terminal Equipment (ONT) unit for Passive Optical Networks (PON) termination in an FTTH (Fiber-To-The-Home) service delivery architecture. ONT-RGW 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 RF Overlay), and WPS (WiFi Protected Setup). The use of the GPON fiber access technology does allow a significant service delivery increase when compared with traditional xDSL technologies.

The ONT-RGW equipment technology is based on GEM (GPON Encapsulation Method), and complies with ITU-T
G.984.x. recommendation as like G.984.4 (OMCI) ensuring interoperability with major GPON OLT vendors
(BBF.247).

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, makes the GPON technology and the ONT-RGW the most efficient option for passive optical network topologies when integrated service delivery is an issue.

Together with multi-vendor OLT interoperability (BBF.247 certified), other differentiated features of the ONT-RGW product are the embedded RF Video Overlay as well as the chance to have several TV channel packs by means of using remote-managed analog RF video overlay filters. The use of an embedded optical reflective component also increases probing resolution in the case of FTTH probing.

The ONT-RGW is also one of the first single-household integrated CPE solutions (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 64 CPEs. All the Optical Distribution Network is built by means of passive equipment modules with a long-live MTBF standard and very low OPEX.

ONT-RGW MAIN FUNCTIONALITIES

The ONT is aimed at customer premises and complies with the ITU-T G.984.x recommendation in order to transport (over GPON) and deliver (to the premises domain) the full pack of broadband services.

Broadband service applications are commonly referred to as below:

• High-speed internet (HSI);
• Voice (VoIP) services (SIP/MEGACO H.248);
• TV (whether IPTV or analog RF video overlay);
• WiFi.

The multiplay environment is thus reinforced when combining the upper referred services.

INTEROPERABILITY

The ONT gateway 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, Figure 2, as defined by ITU-T G.984.3, ITU-T G.984.4, and ITU-T G.988.

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 equipment integrates gateway functionalities. Link layer configuration and management are achieved by the use of OMCI, while IP-based services (RG functionality and Voice over IP) are configured and managed by TR-069,

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. it is shown a scenario for a multi-service user domain basic architecture through an ISP network.

Optical fiber Internet service user access

In the upstream direction, the ONT-RGW 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 ONT-RGW 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 high-speed data and video services;
• Two FXS ports, which can be connected to telephone sets to provide VoIP services;
• Two Wi-Fi antennas, which can connect to Wi-Fi terminals wirelessly to provide a secure and reliable high-speed wireless network;
• Two USB ports, which can be connected to a USB storage device to provide convenient storage and file-sharing services within a home network;
• One RF Overlay port, which can be connected to a TV set to provide high-quality CATV service.

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 the TDM layer to Ethernet.
