LAIS
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 1 prior to scrambling except for the
section overhead.
DS:
The DS bit is set to logic one to disable the scrambling of the STS-12c/STM-4-4c stream.
When DS is a logic zero, scrambling is enabled.
Reserved:
The reserved bits must be programmed to logic zero for proper operation.
