Re: STM-M out of STM-N (M<N)

["manoj juneja" <manojkumarjuneja@hotmail.com>]

Hi Marteen,
              Thank You for u prompt response. I have another doubt relate 
to this one. If I want to allocate STM64c within STM-256, then what will be 
the difference between the label value if I allocate VC-4-64c within 
STM-256. As per my understanding, the transparency should also be included 
in STM64c request (generalized label request object) and label will be same.

Please comment.

Regards,
manoj.
