VPI/VCI (LLC-Multiplexing or PPP-Encapsulation)
VPI #= 0
VCI #= 38
ATM QoS Type= UBR
Peak Cell Rate (PCR)= 0
Sustain Cell Rate (SCR)= 0
Maximum Burst Size (MBS)= 0
DESCRIPTION
The valid range for the VPI is 0 to 255. Enter the VPI assigned to
you.
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.
Select CBR (Constant 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.
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.
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. Note that system default is 0 cells/sec.
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.
