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/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 802.11n standards that can provide speed
rate up to 30Mbps or 300Mbps when used with other 802.11n wireless products (the speed rate
varies depends on the model that your purchase). To enhance wireless connections to reach
further, the 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/WPA-Mixed 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.
