Introduction
A GPON is a network of passive optical networks (PON) type. It is one of the most effective state-of-the-art solutions of the last mile issue that enables
cable economy and provides information transfer 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 device is designed to connect user
terminal equipment to broadband access services. It can be used in residential areas and office buildings.
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-

Product Description
Purpose
NTU-RG GPON ONT (Gigabit Ethernet Passive Optical Network) devices represent high-performance user terminals designed to establish a connection
with upstream passive optical network equipment and to provide broadband access services to the end user. GPON connection is established through the
PON interface, while Ethernet interfaces are used for connection of terminal equipment.
The key GPON advantage is the optimal use of bandwidth. This technology is considered as the next step in provisioning of new high-speed Internet
applications at home and office. Being developed for network deployment inside houses or buildings, these ONT devices provide robust connection with
high throughput and at long distances for users living and working at remote apartment and office buildings.
An integrated router allows local network equipment to be connected to a 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 enable IP telephony and provide 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.
Notes contain important information, tips, or recommendations on device operation and setup.
Warnings inform users about hazardous conditions which may cause injuries or device damage and may lead to the device malfunctioning or
data loss.

USB ports can be used for USB-enabled 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, NTU-RG-5421GC-Wac, NTU-RG-5440G-WZ, NTU-RG-5440G-Wac 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 1733 Mbps 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, NTU-RG-5440G-WZ come 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.
NTU-RG-5421GC-Wac device has an integrated RF output, to which a TV is connected to watch analog or digital cable television (if the service is provided
by the carrier).
