A description of an AHDLC engine.

The statistics associated with an AHDLC engine.

An arbitrary non-zero integer-value that uniquely
identifies an AHDLC engine.  An implementation should
assign AHDLC engines consecutive monotonically
increasing values.

Textual name of the AHDLC engine.  The value of this
object should be the name of the component as
assigned by the local device.

AHDLC engine type.  Three main types are defined:
- a 'hardware' based engine requires the use of
AHDLC hardware assist.  Each hardware based engine is
peer to one unique AHDLC hardware assist.
- a 'software' based engine is not peer to an AHDLC
hardware assist but it relies on the system cpu(s) to
perform AHDLC framing.
If the engine type cannot be determined, this object
value should return 'unknown'.

Number of current active channels handled by this
engine.

Maximum number of channels that can be supported
by this engine.

Maximum number of channels configured by the user.
This value may not be higher than
cCdmaAhdlcEngineMaxChannels.

This object defines the current AHDLC engine
operational state.  The 'up' indicates the engine
is ready to receive ahdlc packets.
If cCdmaAhdlcEngineAdminState is 'down' then
cCdmaAhdlcEngineOperState should be 'down'.  If
cCdmaAhdlcEngineAdminState is changed to 'up' then
cCdmaAhdlcEngineOperState should change to 'up'
if the engine is ready to receive ahdlc packets;
it should remain in the 'down' state if and only
if there is a fault that prevents it from going to
the 'up' state.

This object defines the AHDLC engine desired
state.  When a managed system initializes, all
interfaces start with 'down' state.  As a result
of either explicit management action or per
configuration information retained by the managed
system, cCdmaAhdlcEngineAdminState is then changed
to either 'up' or remains in the 'down' state.

 'true' indicates notification will be sent out
when cCdmaAhdlcEngineAdminState is 'up' and
cCdmaAhdlcEngineOperState is 'down'.

Corresponding AHDLC service adapter entry in
the ENTITY-MIB (RFC-2737).  This object value should
return the corresponding entPhysicalIndex value of
the service adapter or 0 if it cannot be determined or
is not applicable.

Total number of outgoing-traffic octets delivered to the
AHDLC engine for AHDLC encoding since agent rebooted.

Total number of outgoing-traffic octets generated by the
AHDLC engine through AHDLC encoding since agent rebooted.

Total number of outgoing-traffic packets delivered to the
AHDLC engine for AHDLC encoding since agent rebooted.

Total number of outgoing-traffic packets generated by the
AHDLC engine through AHDLC encoding since agent rebooted.

Total number of incoming-traffic octets delivered to the
AHDLC engine for AHDLC decoding since agent rebooted.

Total number of incoming-traffic octets generated by the
AHDLC engine through AHDLC decoding since agent rebooted.

Total number of incoming-traffic packets delivered to the
AHDLC engine for AHDLC decoding since agent rebooted.

Total number of incoming-traffic packets generated by the
AHDLC engine through AHDLC decoding since agent rebooted.

The number of packets dropped by the engine during AHDLC
decoding since agent rebooted.

The number of packets dropped by the engine during AHDLC
encoding since agent rebooted.

The number of packets dropped by the engine because
of CRC errors since agent rebooted.

The number of packets dropped by the engine due to
insufficient memory during AHDLC decoding since
agent rebooted.

The number of packets dropped by the engine due to
insufficient memory during AHDLC encoding since
agent rebooted.

The number of packets dropped by the engine due to
queue overflow during AHDLC decoding since agent
rebooted.

The number of packets dropped by the engine due to
queue overflow during AHDLC encoding since agent
rebooted.

The number of packets dropped by the engine due to
invalid size during AHDLC decoding since agent
rebooted.

The number of packets dropped by the engine due to
invalid size during AHDLC encoding since agent
rebooted.

The value of sysUpTime on the most recent occasion at
which any one or more of this interface's counters
suffered a discontinuity.

A list of AHDLC engines available in the system.

A list of statistics for those AHDLC engines
supported by the system.

This notification indicates an AHDLC engine
is 'down' due to some fault though the desired
state of the engine is 'up'.

This MIB module provides details concerning AHDLC
engine state, performance, configuration and
notification.
An AHDLC channel handles one AHDLC session.
AN AHDLC engine controls a set of AHDLC channels.

over AHDLC
Two types of AHDLC engines are available
software and hardware based.  A dedicated hardware
allows better ahdlc framing performance.
