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 (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.
Cell rate configuration often helps eliminate traffic congestion that slows
transmission of real time data such as audio and video connections.
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.
sent at the peak rate. Type the MBS, which is less than 65535.
