Encapsulation

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

box. Choices vary depending on the mode you select in the Mode field.
If you select Bridge in the Mode field, select either PPPoA or RFC 1483.
If you select Routing in the Mode field, select PPPoA, RFC 1483, ENET

ENCAP or PPPoE.

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

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)

The schedule rule(s) in SMT menu 26 have priority over your Connection

settings.

Nailed-Up

Connection

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

The Prestige will try to bring up the connection automatically if it is disconnected.
