AU4 to AU3 Bypass Mode
The Bypass path supports AU4 to AU3 Bypass Mode. The incoming and outgoing frame
configuration are different. Details of the frame configurations supported are shown in Section
13.6.5 but in general do not contain TUG2’s.
•
AU4 to AU3 Bypass Mode is a simultaneous mode.
AU4 to AU3 Bypass Mode can be implemented using the same configuration as for Bypass
STS-1 Mode as shown in Table 31.
In this mode, the RTTB336 and RTOP336 may be enabled for the AU4 timeslot(s) to process
the VC3 path overhead. This is the only time that the RTTB336 and RTOP336 should be
enabled for bypass traffic.
AU4/VC4/TUG3/TU3/VC3/C3 -> 3x AU3/VC3/C3
