The P1P0S1S2S3S4FR octet carries T1 framing in the F bit and channel
associated signaling in the P1P0and S1S2S3S4bits. Channel associated signaling
is optional. 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 18
shows the channel associated signaling bit mapping and how the phase bits
locate the sixteen state CAS mapping as well as T1 frame alignment for super
frame and extended superframe formats. When using four state CAS then the
signaling bits are A1-A24, B1-B24, A1-B24, B1-B24 in place of are A1-A24, B1-
