6 NTU Optical Network Terminals
2 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, NTU-RG-1421GC-Wac and NTU-RG-1421G-WZ 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 Wi-Fi 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).
NTU-RG-1421G-WZ comes with Z-Wave module, which is used for “Smart Home” service providing.
Z-Wave is a wireless radio technology with low power consumption, which was designed specially for
remote control. In contrast with Wi-Fi and others IEEE 802.11 data transmission standards, that were designed
for large data streams, Z-Wave operates within frequency range up to 1 GHz and is optimized for the
transmission of simple control commands with low delays (for example, turn on/off, modify the volume,
brightness, etc.). The choice of low radio-frequency range for Z-Wave is caused by a small quantity of potential
interfering sources (in contrast with the high-usage 2.4 GHz band, which requires measures reducing possible
interferences from different home wireless appliances - Wi-Fi, ZigBee, Bluetooth).
Z-Wave is designed for creation of affordable and power-efficient consumer electronics, including battery-
operated devices such as remote controllers, smoke sensors, temperature sensors, humidity sensors, motion
sensors and other protective sensors.
