Note:
1. SMF indicates the sub-multiframe.
2. Ai–Di are the per channel signaling bits.
3. X0–X2 are the X spare bits normally set to 1.
4. Y is the Remote Multiframe Yellow Alarm Indication bit. When Y is set to a 1, this indicates that the alarm is active.
5. The Multiframe Alignment Sequence (MAS) is defined as the time slot 16 word that contains the 0000XYXX sequence.
