DALGO

DALGO:

The DALGO bit determines the criteria used to decode a valid B3ZS

signature. When DALGO is set to logic 1, a valid B3ZS signature is declared

and 3 zeros substituted whenever a zero followed by a bipolar violation of the

opposite polarity to the last observed BPV is seen. When the DALGO bit is

set to logic 0, a valid B3ZS signature is declared and the 3 zeros are

substituted whenever a zero followed by a bipolar violation is observed.

SALGO:

The SALGO bit determines the criteria used to establish a valid B3ZS

signature used to map BPVs to line code violation indications. Any BPV that

is not part of a valid B3ZS signature is indicated as an LCV. When the

SALGO bit is set to logic 1, a valid B3ZS signature is declared whenever a

zero followed by a bipolar violation is observed. When SALGO is set to logic

0, a valid B3ZS signature is declared whenever a zero followed by a bipolar

violation of the opposite polarity to the last observed BPV is seen.

EXZDET:

The EXZDET bit determines the type of zero occurrences to be included in

the LCV indication. When EXZDET is set to logic 1, the occurrence of an

excessive zero generates a single pulse indication that is used to indicate an

LCV. When EXZDET is set to logic 0, every occurrence of 3 consecutive

zeros generates a pulse indication that is used to indicate an LCV. For

example, if a sequence of 15 consecutive zeros were received, with
