### Description

```asn1
backplaneHeartbeat OBJECT-TYPE
SYNTAX INTEGER {
heartBeatPresent (1),
heartBeatAbsent (2),
notSupported (3)
}
ACCESS read-only
STATUS mandatory
DESCRIPTION
"This object reports on the status of the backplane protocol heartbeat.
This object is applicable only to intelligent MIMs residing in an MMAC
chassis.
If the heartbeat is detected from the management module (i.e. the
intelligent MIM is in communication with the management module) then
the value returned by this object is heartBeatPresent(1).
If the heartbeat is not present, then the returned value is
heartBeatAbsent(2).
On intelligent MIMs that do not support the backplane protocol and
management modules the value notSupported(3) is returned."

**Classification**: MIB object for network management
