For example, change VCCMask indexed combination zero (0) from VPI = 0 bits and VCI = 12 bits to
VPI = 3 bits and VCI = 9 bits.
Use to change the VPI/VCI values to 3/9.

PVCs can be configured for port A1 using VPI values from 0 to 7 and VCI values from 0 to 511.
Do not set the VCI part of the VCCMask to fewer than 5 bits.
