Step Action
1 Configure 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.
