is optional. The R bit is reserved and is set to 0. The P

indicate the phase of the channel associated signaling and the S

bits are
the channel associated signaling bits for the 24 DS0 channels in the T1. Table 27
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-
B24, C1-C24, D1-D24. When using 2 state CAS there are only A1-A24 signaling
bits.
