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)
–
–
•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
•QoS Sustainable Cell Rate
Enter the QoS Sustainable Cell Rate (SCR) value supplied by your service provider. Use for
•QoS Maximum Burst Size
Enter the QoS Maximum Burst Size (MBS) value supplied by your service provider. Use with
•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
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.
