### Description

```asn1
mscMpanlDlciABitReasonFromIf OBJECT-TYPE
SYNTAX INTEGER {
notApplicable(0),
remoteUserSignaled(1),
remoteLmiError(3),
remoteLinkDown(5),
vcDown(6) }
ACCESS read-only
STATUS mandatory
DESCRIPTION
"This attribute provides the reason (if any) for an inactive status to be
sent to the subnet. This reason is not applicable for an active status.

A-Bit status reason description:
The A-Bit status reason is notApplicable when the A-Bit status is
active.
The A-Bit status reason is remoteUserSignaled if the SPVC end
point originating the A-Bit status has detected that the DLCI is
inactive at the remote network through the LMI protocol. The
SPVC end point must be running network site LMI protocol for this
A-Bit status reason to be sent.
The A-Bit status reason is remoteLmiError if the LMI protocol is
down at the SPVC end point originating this A-Bit status reason.
The A-Bit status reason is remoteLinkDown if the physical
interface is disabled at the SPVC end point originating this A-Bit
status reason.
The A-Bit reason is vcDown if no A-Bit status has been received
from the interface (i.e., no A-Bit status has been relayed)."
DEFVAL { vcDown }
