92 Chapter 6 WAN Setup

The VBR-nRT (non real-time Variable Bit Rate) type is used with bursty connections that do

not require closely controlled delay and delay variation. It is commonly used for "bursty"

traffic typical on LANs. PCR and MBS define the burst levels, SCR defines the minimum

level. An example of an VBR-nRT connection would be non-time sensitive data file transfers.

6.4.1.3 Unspecified Bit Rate (UBR)

The Unspecified Bit Rate (UBR) ATM traffic class is for bursty data transfers. However, UBR

doesn't guarantee any bandwidth and only delivers traffic when the network has spare

bandwidth. An example application is background file transfer.

6.5 Zero Configuration Internet Access

Once you turn on and connect the ZyXEL Device to a telephone jack, it automatically detects

the Internet connection settings (such as the VCI/VPI numbers and the encapsulation method)

from the ISP and makes the necessary configuration changes. In cases where additional

account information (such as an Internet account user name and password) is required or the

ZyXEL Device cannot connect to the ISP, you will be redirected to web screen(s) for

information input or troubleshooting.

Zero configuration for Internet access is disabled when

• the ZyXEL Device is in bridge mode

• you set the ZyXEL Device to use a static (fixed) WAN IP address.

6.6 Internet Access Setup

To change your ZyXEL Device’s WAN remote node settings, click Network > WAN. The

screen differs by the encapsulation.

See Section 6.1 on page 87 for more information.
