1 INTRODUCTION
A GPON is a network of passive optical networks (PON) type. It is one of the most effective state-of-theart 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 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-2V with two Ethernet user network interfaces (UNI) – 1 Ethernet 10/100 Base-T port, 1
Ethernet 10/100/1000 Base-T port – and one FXS port;
NTU-RG-1402G-W, which are designed to support four UNI: 10/100/1000Base-T, FXS, Wi-Fi, and
USB.
The Operation Manual describes application, key specifications, configuration, monitoring, and software
retrofit for NTU-RG optical terminals and NTU-2V devices.

2 DEVICE DESCRIPTION
2.1 Application
NTU-2V and NTU-RG GPON ONT (Gigabit Ethernet Passive Optical Network) devices represent highperformance 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.
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 ports 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.
USB ports can be used for connection of USB devices (USB flash drives, external HDD).
NTU-RG-1402G-W network router allows Wi-Fi clients to be connected using IEEE 802.11b/g/n standard.
NTU-RG-1402G-Wac network router supports 802.11ac standard that ensures a record-breaking data transfer
rate of 1 Gbps and allows wireless network to be used for delivery of modern high-speed services to client
equipment.

– Wi-Fi module for wireless interface of the device.
A device with factory (initial) settings have the following logical blocks (see Fig. 6):
br0;
Voice (IP telephony);
eth0…3;
FXS0…1;
wl0.
br0 is used to combine LAN ports in one 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 br0 block.
The FXS0..1 blocks are ports with RJ-11 connectors for connection of analog phones. They are logically
included into the Voice block. The Voice block can be controlled through web interface or remotely with ACS
server through TR-069 protocol. The block specifies VoIP service parameters (SIP server address, phone
numbers, VAS, etc.).
The wl0 block is an interface for Wi-Fi module connection.
A connection to optical device (successful connection to an OLT) additionally create the gpondef,
gpon1232..1236, gpon1232.2..1236.6, bronu0, bronu255, veip0, and bronu255.19 (ACS) blocks with the help
of the OMCI protocol (ONT Management and Control Interface). Blocks enumeration is configured in OLT.
The ACS block is used for device remote control with the help of the ACS server (Auto Configuration
Server). The block is used for communication with subscriber's equipment and processing of queries from NTP
devices and enables services.
