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.

1.2 Management Options

Management options available in this Residential Gateway are listed below:



Web Management

Web Management is of course done over the network. Once the Residential Gateway

is on the network, you can login and monitor the status remotely or locally by a web

browser. Local console-type Web management, especially for the first time use of

Residential Gateway to set up the needed IP, can also be done through any of the

four 10/100Base-TX 8-pin RJ-45 ports located at the front panel of the Residential

Gateway. Direct RJ45 LAN cable connection between a PC and Residential Gateway

is required for this.



SNMP Management

(See

3. SNMP NETWORK MANAGEMENT

for detailed

descriptions.)

1.3 Interface Descriptions

Before you start to configure your device, it is very important that the proper cables with the

correct pin arrangement are used when connecting the Residential Gateway to other

devices such as switch, hub, workstation, etc. The following describes correct cables for

each interface type.



WAN 100Base-FX Fiber Port

1x100Base-FX Fiber port is located within the upper-left corner of the front top of the

Residential Gateway.

This port is primarily used for up-link connection and will

always operate at 100M/Full Duplex mode.

Duplex SC or WDM Simplex SC types of

connectors are available. Use proper multimode or single-mode optical fiber to

connect this port with other Fast Ethernet Fiber port.



LAN 10/100Base-TX RJ-45 Ports

4x10/100Base-TX 8-pin RJ-45 ports are located at the front of the Residential

Gateway. These RJ-45 ports allow user to connect their traditional copper based

Ethernet/Fast Ethernet devices into network.

All these ports support auto-negotiation

and MDI/MDIX auto-crossover, i.e. either crossover or straight through CAT-5 cable

may be used.

Since there is no separated RJ-45 Management Console port for this Residential

Gateway, however any of these four 10/100Base-TX RJ-45 ports can be used

temporarily as the RJ-45 Management Console Port for local management. This

temporary RJ-45 Management Console Port of the Residential Gateway and a RJ-45

LAN cable for PC connections are required to connect the Residential Gateway and a

PC. Through these, the user then can configure and check the Residential Gateway

even when the network is down.

1.4 Connecting the Residential Gateway

Before starting to configure the Residential Gateway, you have to connect your devices

correctly. When you connect your device correctly, the corresponding LEDs will light up.



Connect the power adaptor to the power port of the Residential Gateway on the back,

and the other end into a wall outlet. The Power LED should be ON.



The system starts to initiate. After completing the system test, the Status LED will light

up.



CAUTION:

For the first-time configuration, connect one end of an Ethernet patch

cable (RJ-45) to any ports on the front panel and connect the other end of the patch

cable (RJ-45) to the Ethernet port on Administrator computer. LAN LED for the

corresponding port will light up.



Connect one end of an Ethernet patch cable (RJ-45) to other LAN ports of the Router

10

and connect the other end of the patch cable (RJ-45) to the Ethernet port on other

computers or Ethernet devices to form a small area network. The LAN LED for that

port on the front panel will light up.



Connect the Fiber cable provided from your service provider to the WAN Fiber port

on the back panel, the WAN LED will light up and blinking if data are transmitting.

1.5 RF over Fiber (With RF Receiver only)

Fiber Optic RF Receiver with SC/APC connector is located within the upper-left corner of the

top-front of the WLAN Residential Gateway.

This port is primarily used for CATV RF link

connection and will operate at output level greater than 24dBmV@-5dBm of optical input

with 77 NTSC or 60 PAL channels of loading. Use proper RF optical fiber to connect this

port with other fiber port at the CATV head end. Also use TV Coaxial Cable to connect the

TV with the TV coaxial cable female connector located in the front of the WLAN Residential

Gateway. There are three LEDs beside the TV coaxial cable connector to indicate the status

of TV/RF Output, RF Fiber Link status, and Power status respectively. See below for CATV

LED descriptions.
