Step Action

1Configure the following parameters for each session:

•Session Name

Enter a unique, descriptive identifier for the session. This name can have a maximum of 32 characters.

•Virtual Path ID (VPI)

Enter the value (from 0 to 4,095) provided by the service provider. The number identifies the virtual path that transports ATM cells between the modem and the service provider. This value must match the virtual path identification (VPI) value the service provider uses for this connection.

•Virtual Channel ID (VCI)

Enter the value (from 32 to 65,535) provided by the service provider. The number identifies the virtual channel for this session that transports ATM cells between the modem and the service provider. This value must match the virtual channel identification (VCI) value the service provider uses for this connection.

•ATM QoS

Select the ATM Quality of Service indicated by your service provider. The options are:

–UBR (unspecified bit rate is the default setting)

–CBR (constant bit rate)

–VBR-rt(variable bit rate real-time)

–VBR-nrt(variable bit rate non-real-time)

•QoS Peak Cell Rate

Enter the QoS Peak Cell Rate (PCR) value supplied by your service provider. If you are not provided a PCR value, use the default. PCR is the maximum rate at which data is transferred on the line and measured in ATM cells per second. The valid range is 1-5500 cells per second. The default PCR is 5500.

•QoS Sustainable Cell Rate

Enter the QoS Sustainable Cell Rate (SCR) value supplied by your service provider. Use for VBR-rt, and VBR-nrt ATM QoS. SCR is the average rate at which ATM cells are transferred, measured in cells per second. The SCR must be less than the PCR. The valid range is 1-5500 cells per second.

•QoS Maximum Burst Size

Enter the QoS Maximum Burst Size (MBS) value supplied by your service provider. Use with VBR-rt and VBR-nrt QoS. MBS is the maximum number of cells that can be transmitted at the peak cell rate. The MBS rate must be equal to or less than the PCR. The default MBS is 0.

•LLC Header

Select either true or false for the LLC header. The default is false. False indicates that VCMux encapsulation is used. True indicates that LLC/Snap encapsulation is used.

•IP Address

The IP address is dynamically served by the service provider for this session. When the modem has received the IP address for this session, it displays the value in this field. Also, the IP address dynamically received for the first PPP session set up is assigned as the default gateway (see “Add a Default Gateway” on page 5-4).

If the service provider does not dynamically provide an IP address, they can give you a static IP address that you can enter in this field.
