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

Manoj,

In pure SDH, you can not allocate STM-64 within STM-256. You can allocate
VC-4-64c link connection within a HOVC link. The associated timeslot is an
AU-4-64c, which is identified in EDCBA terminology with 10000, 20000, 30000, or
40000. If you look in my g707-gmpls-label-conversion document, you see that 

10000 maps on S U =   1 0
20000 maps on S U =  65 0
30000 maps on S U = 129 0
40000 maps on S U = 193 0

KLM in all cases is 000 (i.e. non relevant).

As it is a contiguous concatenated signal, there is just 1 label, identifying
the first timeslot. Assume you want to pass the VC-4-64c via AU-4-64c 20000,
then the label looks like:
    
    0                   1                   2                   3 
    0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 
   +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ 
   |  ST=6         |      RCC=1    |              NCC=64            | 
   +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ 
   |              NVC=0            |        Multiplier (MT)=1      | 
   +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ 
   |                       Transparency (T)=0                      | 
   +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ 
    
 
    0                   1                   2                   3 
    0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 
   +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ 
   |               S=65             |   U=0 |   K=0 |   L=0 |   M=0 |
