AISDET:

The AISDET bit determines the line AIS alarm detection algorithm. When

AISDET is a logic one, line AIS is declared when a 111 binary pattern is

detected in bits 6, 7, and 8 of the K2 byte for three consecutive frames. When

AISDET is a logic zero, line AIS is declared when a 111 binary pattern is

detected in bits 6, 7, and 8 of the K2 byte for five consecutive frames.

ALLONES:

The ALLONES bit controls the conditioning that occurs whenever line AIS is

detected in the recovered data. When ALLONES is a logic one, the

recovered data is forced to logic one immediately when the line AIS alarm is

detected. When line AIS is removed, the recovered data is passed

unconditioned. When ALLONES is a logic zero, recovered data conditioning

is disabled regardless of the state of the line AIS alarm.

BIPWORD:

The BIPWORD bit controls the accumulation of B2 block errors. When

BIPWORD is a logic one, one or more B2 errors per frame result in a single

error accumulated in the B2 error counter. When BIPWORD is a logic zero,

each B2 error is accumulated in the B2 error counter.
