1Introduction
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 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 the following terminals:
NTU-2V(C) with two Ethernet user network interfaces (UNI): 1 Ethernet 10/100 Base-T port, 1 Ethernet
10/100/1000 Base-T port and 1 FXS port, and also equipped with the integrated Triplexer1transceiver
depending on the device model;
NTU-2W with two Ethernet user network interfaces (UNI): 1 Ethernet 10/100 Base-T port and 1
Ethernet 10/100/1000 Base-T port;
NTU-RG-1402G-W, which are designed to support four UNI: 10/100/1000Base-T, FXS, Wi-Fi, and USB.
This operation manual describes intended use, main specifications, configuration, monitoring, and firmware
update for optical terminals NTU-2V(C), NTU-2W, NTU-RG-1402G-W.

2Product Description
2.1 Purpose
NTU-2V(C), NTU-2W, NTU-RG-1402G-W GPON ONT (Gigabit 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.
Terminals use firewalls to secure network computers from DoS and virus attacks, provide packet filtering for
access control based on ports and source/destination MAC/IP addresses. Users can configure home or office
websites by adding one of the LAN-ports to the DMZ. Parental Control feature filters out websites with
unwanted content, block domains, and defines the Internet usage schedule. 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.
NTU-2VC is equipped with the integrated Triplexer transceiver that enables simultaneous data transmission
and provisioning of the CaTV services.
USB ports can be used for USB-enabled devices (USB flash drives, external HDD).
NTU-2W and NTU-RG-1402G-W subscriber routers allow connection of Wi-Fi clients via IEEE 802.11b/g/n
standard.
2.2 Models
NTU-2V(C), NTU-2W and NTU-RG-1402G-W devices are designed to support various interfaces and
