1. INTRODUCTION
Thank you for purchasing the WLAN Residential Gateway
which is designed to aim at FTTX
applications. This WLAN Residential Gateway provides four TP ports for LAN applications,
one fiber optic or TP port for WAN, two sets of FXS telephony ports and built-in IEEE
802.11b/g or 802.11b/g/n wireless LAN (To use CATV application, please purchase the
WLAN Residential Gateway with RF module installed). The combination of wireless and
VoIP function provides users not only more flexible ways to enjoy bandwidth-intensive
services but also more secure internetwork connections by implementing packet or URL
filtering policies.
The wireless function of this Gateway conforms to IEEE 802.11b/g/n standards that can
provide speed rate up to 30Mbps or 80Mbps when used with other 802.11b/g/n wireless
products (the speed rate varies depends on the model that your purchase). To enhance
wireless connections to reach further, detachable SMA antennas, dispersing the same
amount of power in all directions, can be used to receive and deliver stable and high-gain
transmissions. The WLAN Residential Gateway also supports WPA/WPA2 authentication
methods and 64/128-bit data encryption to implement strict security protection so as to
prevent your wireless networks from unauthorized uses or possible malicious attacks. Other
security mechanisms provided that can protect your network including the uses of disabling
SSID broadcast function, MAC filtering, URL filtering, DDoS protection.
For VoIP applications, the internationally recognized standards, SIP (Session Initiation
Protocol), have been employed to manage multimedia communication sessions so that
users can use traditional analog telephones to make telephone calls to IP telephones over
the Internet. Calls received from IP telephones work exactly the same as you would expect
from the traditional telephone service. Other WLAN
Residential Gateway’s
features are:
Voice Activity Detection (VAD) / Silence Suppression
which
reduces the bandwidth that a
call uses by not transmitting when you are not speaking; Comfort Noise Generation that is
the background noise the device generates to fill moments of silence when the other device
in a call stops transmitting because the other party is not speaking (as total silence could
easily be mistaken for a lost connection); Echo Cancellation which is WLAN Residential
Gateway’s supporting G.168, an ITU
-T standard for eliminating the echo caused by the
sound of your voice reverberating in the telephone receiver while you talk.
The WLAN Residential Gateway is mainly dedicated to the FTTX broadband service
providers who look for a way of delivering multiple IP services to the home users. The fiber
optic port supports connection distance from 2KM to 20KM or further than 100KM by using
multi-mode optical fiber, single-mode optical fiber (SMF), or bi-direction SMF. The
transmission distance varies depending on the fiber transceiver that your purchase. For
detailed information about fiber transceiver, please refer to Fiber Transceiver Information
PDF in Documentation CD-ROM. To easily manage and maintain the device, advanced
network settings are configurable via Web-based Management such as Firmware upgrade.
The featured NAT and DHCP server functions also allow you to use a hub or switch to
establish a private network depending on your personal needs that allows multiple
computers to share a single Internet connection.
