622.08 Mb/s.

 

 

NumVpiBits

For OC-3c, 11 bits split between NumVpiBits and NumVciBits.

 

NumVpiBits cannot exceed 6 bits for OC-3c.

 

For OC-12c, 13 bits split between NumVpiBits (default is 4) and

 

NumVciBits (default is 9). NumVpiBits cannot exceed 8 bits for

 

OC-12c.

 

 

NumVciBits

This field is read only. It takes remaining bits from NumVpiBits. For

 

example, if NumVpiBits is 3 for OC-3c, then NumVciBits is 8.
