RE: Editorial comments on draft-ietf-ccamp-gmpls-sonet-sdh-00.txt



Dear Sayan,

Thanks for the comments. However note that when requesting transparency for
an STS-48 signal for instance, the signal type to use is STS-48. You cant'
concatenate STS-1's since concatenation of STS-1 is not defined, but
concatenation of STS-1 SPE's is. If you ask the concatenation of 48 x STS-1
SPE's you are not speaking about the frame with its overhead, so you cannot
request transparency. So we took the decision to use well defined signal
types when requesting transparency (e.g. STS-48). And we took the convention
to indicate in NCC the number of SPE's in that signal that must be
concatenated. It took us some time to find a way to code each possible
signal in a non ambiguous way. So I the original examples are correct.

Kind regards,

Eric

Hi ALL,
I noticed the following in section 4 of
draft-ietf-ccamp-gmpls-sonet-sdh-00.txt .

 The example number 16 is ...

16. An STS-48c signal with LOH DCC and E2 transparency is formed
   by the application of CCT with Type 1, NCC with value 48, NVC with
   value 0, MT with value 1 and T with flag 5 and 10 to an STS-48
   Elementary Signal.

It should be 

   An STS-48c signal with LOH DCC and E2 transparency is formed
   by the application of CCT with Type 1, NCC with value 48, NVC with
   value 0, MT with value 1 and T with flag 5 and 10 to an STS-1 SPE
   Elementary Signal.

The example number 17 is ...

17. An STS-768c signal with K1/K2 and LOH DCC transparency is
   formed by the application of CCT with Type 1, NCC with value 768,
   NVC with value 0, MT with value 1 and T with flag 5 and 7 to an
   STS-768 Elementary Signal.

It should be 

   An STS-768c signal with K1/K2 and LOH DCC transparency is
   formed by the application of CCT with Type 1, NCC with value 768,
   NVC with value 0, MT with value 1 and T with flag 5 and 7 to an
   STS-1 SPE Elementary Signal.
