LABEL

DESCRIPTION

 

 

Name

Enter the name of your Internet Service Provider, e.g., MyISP. This information is for

 

identification purposes only.

 

 

Mode

Select Routing (default) from the drop-down list box if your ISP allows multiple

 

computers to share an Internet account. Otherwise select Bridge.

 

 

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.

 

VBR is not available on all models.

 

 

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.
