Figure 71 Tributary Path Overhead (TPOH) with non-TU3 Tributary
In the event where the STS-12/STM-4 frame contains TU3 tributaries, the TPOH pin will output
the 9 path overhead bytes (J1, B3, C2, G1, F2, H4, Z3, Z4, and Z5) on its dedicated timeslots. A
summary of the mapping of TU3 overhead byte timeslots to lower order overhead byte timeslots
is shown in Table 48. A complete enumeration of the ordering of path overhead bytes presented
on the TPOH pin is shown in Table 49.
