6 NTU Optical Network Terminals
2 Product 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
features—see Table 1.
