DESCRIPTION

 

Multiplex

Select the method of multiplexing used by your ISP from the drop-down list.

 

 

Choices are VC or LLC.

 

 

 

 

Virtual Circuit ID

VPI (Virtual Path Identifier) and VCI (Virtual Channel Identifier) define a virtual

 

 

circuit. Refer to the appendix for more information.

 

 

 

 

VPI

The valid range for the VPI is 0 to 255. Enter the VPI assigned to you.

 

 

 

 

VCI

The valid range for the VCI is 32 to 65535 (0 to 31 is reserved for local

 

 

management of ATM traffic). Enter the VCI assigned to you.

 

 

 

 

ATM QoS Type

Select CBR (Constant Bit Rate) to specify fixed (always-on) bandwidth for voice

 

 

or data traffic. Select UBR (Unspecified Bit Rate) for applications that are non-

 

 

time sensitive, such as e-mail. Select VBR (Variable Bit Rate) for bursty traffic

 

 

and bandwidth sharing with other applications.

 

 

 

 

Cell Rate

Cell rate configuration often helps eliminate traffic congestion that slows

 

 

transmission of real time data such as audio and video connections.

 

 

 

 

Peak Cell Rate

Divide the DSL line rate (bps) by 424 (the size of an ATM cell) to find the Peak

 

 

Cell Rate (PCR). This is the maximum rate at which the sender can send cells.

 

 

Type the PCR here.

 

 

 

 

Sustain Cell Rate

The Sustain Cell Rate (SCR) sets the average cell rate (long-term) that can be

 

 

transmitted. Type the SCR, which must be less than the PCR. Note that system

 

 

default is 0 cells/sec.

 

 

 

 

Maximum Burst

Maximum Burst Size (MBS) refers to the maximum number of cells that can be

 

Size

sent at the peak rate. Type the MBS, which is less than 65535.

 

 

 

 

Login Information

(PPPoA and PPPoE encapsulation only)

 

 

 

 

Service Name

(PPPoE only) Type the name of your PPPoE service here.

 

 

 

 

User Name

Enter the user name exactly as your ISP assigned. If assigned a name in the

 

 

form user@domain where domain identifies a service name, then enter both

 

 

components exactly as given.

 

 

 

 

Password

Enter the password associated with the user name above.

 

 

 

 

IP Address

This option is available if you select Routing in the Mode field.

 

 

A static IP address is a fixed IP that your ISP gives you. A dynamic IP address is

 

 

not fixed; the ISP assigns you a different one each time you connect to the

 

 

Internet.

 

 

Select Obtain an IP Address Automatically if you have a dynamic IP address;

 

 

otherwise select Static IP Address and type your ISP assigned IP address in

 

 

the IP Address field below.

 

Connection

 

 

(PPPoA and PPPoE

 

 

encapsulation only)

 

 

 

 

 

Nailed-Up

Select Nailed-Up Connection when you want your connection up all the time.

 

Connection

The ZyXEL Device will try to bring up the connection automatically if it is

 

 

disconnected.

 

 

 

 

Connect on

Select Connect on Demand when you don't want the connection up all the time

 

Demand

and specify an idle time-out in the Max Idle Timeout field.

 

 

 

 

Max Idle Timeout

Specify an idle time-out in the Max Idle Timeout field when you select Connect

 

 

on Demand. The default setting is 0, which means the Internet session will not

 

 

timeout.
