The SCR maps directly to the minimum cell rate (MCR). The MCR defines the

minimum amount of guaranteed bandwidth allowed for the default VC on the

ATM line.

When setting the SCR, keep the following in mind:

• To be useful, the SCR must not exceed the PCR.

• If you know the average rate, set the SCR approximately 10 percent higher

than this value.

• VCs may fail to operate with SCR values lower than 128 cells/s.

• Entering 0 for the SCR turns off this function.

After you determine the transmission rate of your ATM device, set the sustainable

cell rate within the specified range.

To change the receive SCR for the default VC, complete the following tasks:
