au-3: Gets AUG through AU-3.
au-4: Gets AUG through AU-4.
Usage guidelines
SDH provides two payload mapping/multiplexing solutions: ANSI and ETSI.
• ANSI uses the AU-3 multiplexing scheme, where the lower-order payload is aggregated into the
VC-3 higher-order path. VC-3 plus an AU pointer forms AU-3. Three such AU-3s can be
synchronized and multiplexed to form one AUG.
• ETSI uses the AU-4 multiplexing scheme, where the lower-order payload is aggregated into the
VC-4 higher-order path. VC-4 plus an AU pointer forms an AU-4. This AU-4 can be synchronized
and multiplexed to form one AUG.
When the CPOS interface is operating in SDH mode, you can choose to multiplex AUG to AU-4 or AU-3
by using the multiplex mode command. When the CPOS interface is operating in SONET mode, AUG
can be multiplexed only to AU-3 and the multiplex mode command is invalid.
Examples
# In SDH mode, multiplex AUG to AU-3.
