J0/J1 encoding issues
As mentioned at the CCAMP meeting, the SDH trace bytes (J0/J1/J2)
have restrictions not only on the length of a trace message and on
the bits usable in a octet, but also on whether the payload in the
message uses printable ASCII characters.
The requirements for J0/J1/J2 (found in G.707) state the trace
message payload must utilize the printable characters defined in
T.50. Two current LMP drafts (draft-ietf-ccamp-lmp-test-sonet-sdh &
draft-lang-ccamp-lmp-bootstrap) utilize encodings that are not
consistant with this requirement.
This message is being sent to document this issue. It is not a
statement that no other issues exist -- I expect that the appropriate
experts in the ITU will review the rest of these two drafts and
provide appropriate comment.
