1 Introduction
A GPON is a network of passive optical networks (PON) type. It is one of the most effective state-of-the-art
solutions for the 'last mile' issue that significantly reduces the required amount of cable and provides data
transfer with downlink rate up to 2.5 Gbps and uplink rate up to 1.25 Gbps. Being used in access networks,
GPON-based solutions allow end users to have access to new services based on IP protocol in addition to
more common ones.
The key GPON advantage is the use of one optical line terminal (OLT) for multiple optical network terminals
(ONT). OLT converts Gigabit Ethernet and GPON interfaces and is used to connect a PON network with data
communication networks of a higher level. ONT is designed to connect terminal equipment of user to
broadband access services. ONT can be used in residential estates and offices.
The range of ONT NTU equipment produced by ELTEX comprises of terminals with four UNI interfaces of
10/100/1000Base-T and supports for FXS, Wi-Fi, USB, Z-Wave1 interfaces:
• NTU-RG-5402G-W, NTU-RG-5421G-Wac, NTU-RG-5421G-WZ
This operation manual describes intended use, key specifications, configuration, monitoring, and firmware
update for NTU-RG series optical terminal.

2 Product Description
2.1 Purpose
NTU-RG GPON ONT (Gigabit Ethernet Passive Optical Network) devices represent high-performance network
terminals designed for connection with upstream GPON equipment and providing end user with broadcast
access services. GPON connection is established through PON interface, while Ethernet interfaces are used for
connection of terminal equipment.
The key GPON advantage is the optimal use of bandwidth. The technology is the next step of high-speed
Internet applications for home and office. Being designed for home or office network deployment, these ONT
devices provide users, who live and work in distant flat buildings and business centres, with reliable
connection with high throughput at large distances.
With built-in router, these devices enable connection of local network equipment to broadband access
network. The terminals protect PCs from DoS and virus attacks with the help of firewall and filter packets to
control access based on ports and MAC/IP addresses of source and target.Users can configure a home or
office web site by adding a LAN port into DMZ. Parental Control enables filtration of undesired web sites,
blocks domains and allows for compilation of a schedule of Internet use. Virtual private network (VPN)
provides mobile users and branch offices with a protected communication channel for connection to a
corporate network.
FXS port enables IP telephony and provides various useful features such as display of caller ID, three-way
conference call, phone book, and speed dialling. This makes dialling and call pick-up user friendly.
USB ports can be used for connection of USB devices (USB flash drives, external HDD).
Network router NTU-RG-5402G-W provides the connection via b/g/n Wi-Fi standard and ensures 2.4 GHz
operation of the device. NTU-RG-5421G-Wac, NTU-RG-5421G-WZ network routers allow Wi-Fi clients to be
connected using IEEE 802.11a/b/g/n/ac standard. 802.11ac standard support ensures data transfer rate of
1.3Gbps and allows wireless network to be used for delivery of modern high-speed services to client
equipment. Two integrated Wi-Fi network controllers enable simultaneous 2.4 GHz and 5 GHz dual-band
operation.
NTU-RG-5421G-WZ comes with "Smart Home" controller.
"Smart Home" controller allows organizing an energy-efficient wireless channel specifically for remote control.
Unlike Wi-Fi and other IEEE 802.11 data transmission standards, designed mainly for large streams of
information, the "Smart Home" technology operates in the frequency range up to 1 GHz and is optimized for
transmitting simple control commands with low delays (for example, turn on/off , change the volume,
brightness, etc.). Selection of low radio-frequency range results from the small quantity of potential interfering
sources (unlike the loaded 2.4 GHz band within which it is necessary to resort to measures that reduce
potential interference from various wireless home appliances – Wi-Fi, ZigBee, Bluetooth).
"Smart Home" controller is intended to create low-cost and energy-efficient consumer electronics, including
battery-powered devices such as remote controls, smoke detectors and temperature, humidity, motion sensors
as well as other security sensors.
