DESCRIPTION

DIFF_DELAY_INT
Differential Delay is out of bounds on link
addition/or recovery. This indicates the delay on
the link was out of bounds of the programmed
differential delay and the link failed to come up
for this reason.
This bit is reset immediately after the
read_event command is executed for the group
of which this link is a member.

LODS_OVERRUN_INT
LODS_UNDERRUN_INT
LODS, DCB overrun. An overrun condition
occurred.
This bit is reset immediately after read_event
command is executed for the group of which
this link is a member.
LODS, DCB underrun. Indicates that the DCB
buffer experienced an underrun condition and
has disabled itself from forwarding traffic to the
ATM layer. An underrun occurs when the
transport delay for the link is detected to be
outside the programmed limit and the transport
delay is smaller than the other links within the
group In general, this will happen only if the
transport delay of the link changes. An underrun
condition requires that the link delay be
revalidated prior to being placed back in
service.
This bit is reset immediately after the
read_event command is executed for the group
of which this link is a member.

LCD_INT
LIF_INT
A change of state of the LCD status bit was
detected.
This bit is reset immediately after read_event
command is executed for the group of which
this link is a member.
A change of state of the LIF status bit was
detected.
This interrupt is automatically masked by the
device during a group-wide procedure that
includes this link, such as add_group,
Restart_group, and Start_LASR (for link
addition and link recovery).
This bit is reset immediately after read_event
command is executed for the group of which
this link is a member.
