The following table describes the labels in this screen.
PARAMETRES DESCRIPTION
ATM VC
Virtual Circuit ID
VPI (Virtual Path Identifier) and VCI (Virtual Channel Identifier)
define a virtual circuit.
Status
Activated or Deactivated
VPI
The valid range for the VPI is 0 to 255. Enter the VPI assigned
to you. This field may already be configured.
VCI
The valid range for the VCI is 32 to 65535. Enter the VCI
assigned to you. This field may already be configured.
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.
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.
ENCAPSULATION
Encapsulation
Select the method of encapsulation used by your ISP from the
drop-down list box.
PPPoA/PPPoE
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
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. The Single User
Account feature can be used with either a dynamic or static IP
address.
