Channel associated signaling is optional and only available for SONET/SDH byte synchronously mapped tributaries. The R bit is reserved and is set to 0. The P1P0bits are used to indicate the phase of the channel associated signaling and the S1S2S3S4 bits are the channel associated signaling bits for the 24 DS0 channels in the T1. Table 28 shows the channel associated signaling bit mapping and how the phase bits locate the sixteen state CAS mapping for super frame and extended superframe formats. When using four state CAS then the signaling bits are A1-A24, B1-B24, A1-A24, B1-B24 in place of are A1-A24, B1-B24, C1-C24, D1-D24. When using 2 state CAS there are only A1-A24 signaling bits. For unframed tributaries, the R, P and S bits are unused. When the SYNCH_TRIB bit is set for a tributary, the DS0 alignment is precisely as presented in Table 27, and the P1P0 and S1S2S3S4bits in the first row of Table 28 are aligned to the multiframe indicated by the SDC1FP signal, be it an input or output. The F-bit positions in Table 28 have an arbitrary alignment relative to the P1P0 bits that will change with each controlled frame slip; that illustrated is only an example.
