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.

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. Note that system
