LAIS:

The LAIS bit controls the insertion of line alarm indication signal (AIS). When LAIS is set to logic one, the TSOP inserts AIS into the transmit SONET/SDH stream. Activation or deactivation of line AIS insertion is synchronized to frame boundaries. Line AIS insertion results in all bits of the SONET/SDH frame being set to one prior to scrambling except for the section overhead.

DS:

The DS bit is set to logic one to disable the scrambling of the STS-3c (STM-1) stream. When DS is a logic zero, scrambling is enabled.

Reserved:

The reserved bits must be programmed to logic zero for proper operation.
