Sustain 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.
Maximum Burst
Size
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.
