Account Status

This field displays the current registration status of the SIP account. You have to register

SIP accounts with a SIP server to use VoIP.

Inactive

- The SIP account is not active. You can activate it in

VoIP > SIP > SIP

Account

.

Not Registered

-

The last time the Device tried to register the SIP account with the

SIP server, the attempt failed. Use the

Register

button to register the account again.

The Device automatically tries to register the SIP account when you turn on the Device

or when you activate it.

Registered

-

The SIP account is already registered with the SIP server. You can use it

to make a VoIP call.

Service-Provider

This column displays the service provider name and SIP number for each SIP account.

URI

This field displays the account number and service domain of the SIP account. You can

change these in the

VoIP > SIP

screens.

Overview

This chapter discusses the Device’s

Broadband

screens. Use these screens to configure your

Device for Internet access.

A WAN (Wide Area Network) connection is an outside connection to another network or the

Internet. It connects your private networks, such as a LAN (Local Area Network) and other

networks, so that a computer in one location can communicate with computers in other locations.

3G (third generation) standards for the sending and receiving of voice, video, and data in a mobile

environment.

You can attach a 3G wireless adapter to the USB port and set the Device to use this 3G connection

as your WAN or a backup when the wired WAN connection fails.

•

Use the

Advanced

screen to enable or disable PTM over ADSL, Annex M/Annex J, and DSL PhyR

functions (

Section 5.4 on page 61

).

•

Use the

802.1x

screen to view and configure the IEEE 802.1X settings on the Device (

Section

5.5 on page 62

).

•

Use the

Wan Status

screen to view a WAN interface’s historical traffic transmission rate.

(

What You Need to Know

The following terms and concepts may help as you read this chapter.

Encapsulation Method

Encapsulation is used to include data from an upper layer protocol into a lower layer protocol. To set

up a WAN connection to the Internet, you need to use the same encapsulation method used by your

ISP (Internet Service Provider). If your ISP offers a dial-up Internet connection using PPPoE (PPP

over Ethernet), they should also provide a username and password (and service name) for user

authentication.

WAN IP Address

The WAN IP address is an IP address for the Device, which makes it accessible from an outside

network. It is used by the Device to communicate with other devices in other networks. It can be

static (fixed) or dynamically assigned by the ISP each time the Device tries to access the Internet.

If your ISP assigns you a static WAN IP address, they should also assign you the subnet mask and

DNS server IP address(es).

ATM

Asynchronous Transfer Mode (ATM) is a WAN networking technology that provides high-speed data

transfer. ATM uses fixed-size packets of information called cells. With ATM, a high QoS (Quality of

Service) can be guaranteed. ATM uses a connection-oriented model and establishes a virtual circuit

(VC) between Finding Out More

PTM

Packet Transfer Mode (PTM) is packet-oriented and supported by the VDSL2 standard. In PTM,

packets are encapsulated directly in the High-level Data Link Control (HDLC) frames. It is designed

to provide a low-overhead, transparent way of transporting packets over DSL links, as an

alternative to ATM.

3G

3G (Third Generation) is a digital, packet-switched wireless technology. Bandwidth usage is

optimized as multiple users share the same channel and bandwidth is only allocated to users when

they send data. It allows fast transfer of voice and non-voice data and provides broadband Internet

access to mobile devices.

IPv6 Introduction

IPv6 (Internet Protocol version 6), is designed to enhance IP address size and features. The

increase in IPv6 address size to 128 bits (from the 32-bit IPv4 address) allows up to 3.4 x 10

38

IP

addresses. The Device can use IPv4/IPv6 dual stack to connect to IPv4 and IPv6 networks, and

supports IPv6 rapid deployment (6RD).

IPv6 Addressing

The 128-bit IPv6 address is written as eight 16-bit hexadecimal blocks separated by colons (:). This

is an example IPv6 address

2001:0db8:1a2b:0015:0000:0000:1a2f:0000

.

IPv6 addresses can be abbreviated in two ways:

•

Leading zeros in a block can be omitted. So

2001:0db8:1a2b:0015:0000:0000:1a2f:0000

can be written as

2001:db8:1a2b:15:0:0:1a2f:0

.
