Code
No data
MLHD
(Release hunting, or

Incorrect data
later)
MLHG DN if
MLHG DN is
present, or
Data hunting
was observed
with no
MLHG DN
Corrective Action
The facility is correctly administered and established
with layers 1, 2, and 3 with functioning data capabilities.
The possible causes for this error are:
Incoming data calls using the MLHG DN are not
possible, but incoming data calls using the DN are
possible.
If data hunting is expected, with the administered
MLHG DN, check that the facility is administered
with the MLHG DN provided by the LEC and rerun
the test. If the error persists, contact the LEC.
Incoming data calls using either the MLHG DN or
DN are not possible, and both the MLHG DN and
DN have been verified to be correct.
Readminister the MLHG DN or DN and rerun the
test. If the error persists, contact the LEC.
MLH is not expected
The MLHG DN is not administered and data calls to
the facility using the DN are terminated at the facility
as a hunt call. Contact the LEC.
