CAS Signaling Multi-Frame
starts to search for CAS Signaling Multi-Frame alignment signal if the
CASEN bit is ‘1’.
nibble (Bit 1 ~ Bit 4) of TS16. Its pattern is ‘0000’. When the pattern is
found in TS16 and the high nibble of the previous TS16 are not all zeros,
the Signaling Multi-Frame synchronization is acquired and it is indicated
with a ‘0’ in the OOSMFV bit. The frame containing the Signaling Multi-
Frame alignment pattern is Frame 0 of Signaling Multi-Frame. The TS16
structure of the Signaling Multi-Frame is shown in Figure 13. The entire
content in TS16 of Frame 0 of Signaling Multi-Frame is ‘0000XYXX’. ‘Y’
is for remote Signaling Multi-Frame alarm indication and ‘X’s are extra
bits. The codeword ‘ABCD’ are the signaling bits for different timeslots.
