60 / 92 page  XRT75VL00D E3/DS3/STS-1 LINE INTERFACE UNIT WITH SONET DESYNCHRONIZER REV. 1.0.3 55 Figure 36 was copied directly out of Telcordia GR-253-CORE. However, this figure can be simplified and redrawn as depicted below in Figure 37. FIGURE 36. AN ILLUSTRATION OF TELCORDIA GR-253-CORE’S RECOMMENDATION ON HOW MAP DS3 DATA INTO AN STS-1 SPE FIGURE 37. A SIMPLIFIED "BIT-ORIENTED" VERSION OF TELCORDIA GR-253-CORE’S RECOMMENDATION ON HOW TO MAP DS3 DATA INTO AN STS-1 SPE • For DS3 Mapping, the STS-1 SPE has the following structure. 25I I C3 R 25I I C2 R 25I C1 R R 25I I C3 R 25I I C2 R 25I C1 R R 25I I C3 R 25I I C2 R 25I C1 R R 25I I C3 R 25I I C2 R 25I C1 R R 25I I C3 R 25I I C2 R 25I C1 R R 25I I C3 R 25I I C2 R 25I C1 R R 25I I C3 R 25I I C2 R 25I C1 R R 25I I C3 R 25I I C2 R 25I C1 R R 25I I C3 R 25I I C2 R 25I C1 R R POH 87 bytes R = [r, r, r, r, r, r, r, r] I = [i, i, i, i, i, i, i, i] C1 = [r, r, c, i, i, i, i, i] C2 = [c, c, r, r, r, r, r, r] C3 = [c, c, r, r, o, o, r, s] i = DS3 data r = fixed stuff bit c = stuff control bit s = stuff opportunity bit o = overhead communications channel bit Fixed Stuff 208i s 1r 2o 2r 2c 16r 208i 6r 2c 16r 205i c 18r 208i s 1r 2o 2r 2c 16r 208i 6r 2c 16r 205i c 18r 208i s 1r 2o 2r 2c 16r 208i 6r 2c 16r 205i c 18r 208i s 1r 2o 2r 2c 16r 208i 6r 2c 16r 205i c 18r 208i s 1r 2o 2r 2c 16r 208i 6r 2c 16r 205i c 18r 208i s 1r 2o 2r 2c 16r 208i 6r 2c 16r 205i c 18r 208i s 1r 2o 2r 2c 16r 208i 6r 2c 16r 205i c 18r 208i s 1r 2o 2r 2c 16r 208i 6r 2c 16r 205i c 18r 208i s 1r 2o 2r 2c 16r 208i 6r 2c 16r 205i c 18r r c s i o - Fixed Stuff Bits - Stuff Control/Indicator Bits - DS3 Data Bits - Stuff Opportunity Bits - Overhead Communication Bits POH |
