EXAMPLE – ODU2 in OPU3 TS(1,2,3,4): PJO1 in column 16+1=17, PJO2 in column 16+2=18. ODU2 in OPU3
TS(13,14,15,16): PJO1 in column 16+13=29, PJO2 in column 16+14=30.

The PJO1 for an ODU0 in OPU1 1.25G tributary slot #i (i: 1,2) is located in the first column of OPU1 1.25G
tributary slot #i (OPU1 column 16+i) and the PJO2 is located in the second column of OPU1 1.25G tributary
slot #i (OPU1 column 18+i) in frame #i of the two frame multiframe.
The PJO1 for an ODU1 in OPU2 or OPU3 1.25G tributary slots #a and #b (a: 1..7 or 1..31 respectively; b: 2..8
or 2..32 respectively) is located in the first column of OPUk 1.25G tributary slot #a (OPUk column 16+a) and
the PJO2 is located in the first column of OPUk 1.25G tributary slot #b (OPUk column 16+b) in frames #a
and #b of the eight or thirty-two frame multiframe.

EXAMPLE – ODU1 in OPU2 or OPU3 TS(1,2): PJO1 in column 16+1=17, PJO2 in column 16+2=18. ODU1 in
OPU2 TS(7,8): PJO1 in column 16+7=23, PJO2 in column 16+8=24. ODU1 in OPU3 TS(31,32): PJO1 in column
16+31=47, PJO2 in column 16+32=48.
The eight PJO1s for an ODU2 in OPU3 1.25G tributary slots #a, #b, #c, #d, #e, #f, #g and #h are located in
the first column of OPU3 1.25G tributary slot #a (OPU3 column 16+a) in frames #a, #b, #c, #d, #e, #f, #g and
#h of the thirty-two frame multiframe. The eight PJO2s for an ODU2 in OPU3 1.25G tributary slots #a, #b,
#c, #d, #e, #f, #g and #h are located in the first column of OPU3 1.25G tributary slot #b (OPU3 column 16+b)
in frames #a, #b, #c, #d, #e, #f, #g and #h of the thirty-two frame multiframe. Figure 19-14B presents an
example with two ODU2s and two ODU1s in the OPU3 mapped into 1.25G tributary slots
(1,5,9,10,17,19,20,21), (25,26,27,28,29,30,31,32), (2,3) and (4,24).
EXAMPLE – ODU2 in OPU3 TS(1,2,3,4,5,6,7,8): PJO1 in column 16+1=17, PJO2 in column 16+2=18. ODU2 in
OPU3 TS(25,26,27,28,29,30,31,32): PJO1 in column 16+25=41, PJO2 in column 16+26=42.
