engine state, performance, configuration and
notification.
An AHDLC channel handles one AHDLC session.
AN AHDLC engine controls a set of AHDLC channels.

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

| cCdmaAhdlcMIBNotif | 1.3.6.1.4.1.9.9.997.0 | | | |
| NTF cCdmaAhdlcEngineDownNotif | 1.3.6.1.4.1.9.9.997.0.1 | | | This notification indicates an AHDLC engine
is 'down' due to some fault though the desired
state of the engine is 'up'. |
| cCdmaAhdlcMIBObjects | 1.3.6.1.4.1.9.9.997.1 | | | |
| cCdmaAhdlcEngineInfo | 1.3.6.1.4.1.9.9.997.1.1 | | | |
| cCdmaAhdlcEngineTable | 1.3.6.1.4.1.9.9.997.1.1.1 | | not-accessible | A list of AHDLC engines available in the system. |
| cCdmaAhdlcEngineEntry | 1.3.6.1.4.1.9.9.997.1.1.1.1 | | not-accessible | A description of an AHDLC engine. |
| U32 cCdmaAhdlcEngineIndex | 1.3.6.1.4.1.9.9.997.1.1.1.1.1 | Unsigned32 | not-accessible | An arbitrary non-zero integer-value that uniquely
identifies an AHDLC engine. An implementation should
assign AHDLC engines consecutive monotonically
increasing values. |
| STR cCdmaAhdlcEngineName | 1.3.6.1.4.1.9.9.997.1.1.1.1.2 | SnmpAdminString | read-only | Textual name of the AHDLC engine. The value of this
object should be the name of the component as
assigned by the local device. |
| INT cCdmaAhdlcEngineType | 1.3.6.1.4.1.9.9.997.1.1.1.1.3 | INTEGER | read-only | 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'. |
| G32 cCdmaAhdlcEngineChannelsInUseEx | 1.3.6.1.4.1.9.9.997.1.1.1.1.4 | Gauge32 | read-only | Number of current active channels handled by this
engine. |
| U32 cCdmaAhdlcEngineMaxChannels | 1.3.6.1.4.1.9.9.997.1.1.1.1.5 | Unsigned32 | read-only | Maximum number of channels that can be supported
by this engine. |

This value may not be higher than
cCdmaAhdlcEngineMaxChannels. |
| INT cCdmaAhdlcEngineOperState | 1.3.6.1.4.1.9.9.997.1.1.1.1.7 | INTEGER | read-only | 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. |
| INT cCdmaAhdlcEngineAdminState | 1.3.6.1.4.1.9.9.997.1.1.1.1.8 | INTEGER | read-write | 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. |
| T/F cCdmaAhdlcEngineDownNotifEnabled | 1.3.6.1.4.1.9.9.997.1.1.1.1.9 | TruthValue | read-write | 'true' indicates notification will be sent out
when cCdmaAhdlcEngineAdminState is 'up' and
cCdmaAhdlcEngineOperState is 'down'. |
