The P
P
to indicate the phase of the channel associated signaling and the S
associated signaling bits for the 24 DS0 channels in the T1. Table 9 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.
