The P1P0S1S2S3S4FR octet carries T1 framing in the F bit and channel

associated signaling in the P1P0and S1S2S3S4bits. 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.
