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 2.5Gbps and uplink rate up to 1.25Gbps. Being used in access networks, GPONbased 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 the following terminals:

NTU-RG-1421G-Wac, NTU-RG-1431G-Wac and NTU-RG-1421GС-Wac, which are designed to support
four UNIs: 10/100/1000Base-T, FXS, Wi-Fi, USB, and CaTV1.
This operation manual describes intended use, key specifications, configuration, monitoring, and firmware
update for NTU-RG optical terminal series.

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).
NTU-RG-1421G-Wac, NTU-RG-1431G-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 1.3 Gbps and allows
wireless network to be used for delivery of modern high-speed services to client equipment. Two integrated WiFi network controllers enable simultaneous 2.4GHz and 5GHz dual-band operation.
NTU-RG-1421GC-Wac has a built-in RF port to connect digital and analogue TV (if the service is provided by
your service operator).

ARCHITECTURE OF DEVICES
NTU-RG architecture
Fig. 6—Logical Architecture of a Device with Factory Settings
Main Components of the Device:
–
–
–
optical receiver/transmitter (SFF module) for conversion of an optical signal into electric one
processor (PON chip) which converts Ethernet and GPON interfaces; and
Wi-Fi modules for wireless interfaces of the device.
A device with factory (initial) settings have the following logical blocks (see Fig. 6):
 Br1
 Voice (IP telephony)
 eth0…3
 FXS0
 wl0, wl0.1..wl0.3, wl1, wl1.1..wl1.3
 ppp0.1
 IPInterface
The br1 block here is used to combine LAN ports into a single group.
The eth0..3 blocks physically represent Ethernet ports with RJ-45 connector for connection of PC, STB,
and other network devices. They are logically included into the br1 block.
The FXS0 block is a port with RJ-11 connectors for connection of analogue phone. It is logically included
into the Voice block. The Voice block can be controlled through web interface or remotely with ACS server via
TR-069 standard. The block specifies VoIP service parameters (SIP server address, phone number, VAS, etc.).
The wl0, wl0.1…wl1.3 blocks are the Wi-Fi module connection interfaces. wl0 blocks are the interfaces
designed for 2.4GHz band operation and wl1 blocks are designed for 5GHz band operation.
Filter and Marking blocks enable inclusion of local interfaces into a single group (to br1 block). They deal
with the traffic transmission rules, Filter blocks are responsible for the incoming traffic on the interface, Marking
blocks—for the outgoing one.
____________________________________________________________________________________

____________________________________________________________________________________
IPInterface block is a logical entity that the IP address is provided for the access in LAN and DHCP server
distributing addresses to clients.
The ppp0.1 block is WAN interface of the router. In the factory default configuration, this interface is a
default interface for such services as the Internet, VoIP, TR-069 device management and IPTV.
A connection to OB device (successful connection to an OLT) additionally creates the gpondef block with
the help of the OMCI protocol (ONT Management and Control Interface). This block enables connection of the
subscriber ONT device to the station one.

Security submenu. Security settings
Use this menu to configure general data encryption settings for a wireless network. The client wireless
equipment can be configured either manually or automatically with the help of WPS.
WPS (Wi-Fi Protected Setup)—a standard developed by Wi-Fi Alliance to simplify setup of wireless
networks. The technology allows quick, secure, and simple setup of a wireless network without having in-depth
knowledge of Wi-Fi technology and encryption protocols. WPS automatically sets the network name and
configures data encryption to protect the network from unauthorised access. These operations should be
manually done without WPS.
In order to establish a connection, user simply needs to press the WPS button located on the side panel of
the device or use web configuration to enter PIN code.
WPS Setup
– Enable WPS – to enable WPS access, select Enable from the drop-down list, if WI-FI network adapter of
your device supports this configuration mode
– Set WPS AP mode—sets WPS mode of the access point
Shortcomings of WPS
Wi-Fi routers supporting the WPS technology have a security vulnerability. This vulnerability allows
attackers to retrieve passwords for WPA and WPA2 encryption protocols. The technology is
vulnerable as it allows to brute-force the 8-digit network key (PIN).
Access point manual configuration:
– Select SSID—selects a name of a wireless network from the list
– Network Authentication—selects a network authentication mode from the drop-down list:
