bits are the channel 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.
