*****************
* Standard MIBs *
*****************
Total Control Manager/SNMP supports two standard MIBs:

MIB Filename    Function
------------    --------
DS1.MIB         Provides management of T1 interfaces 
                (based on RFC 1232).

MIB2.MIB        Defines various protocol and administrative 
                information (Full Standard).



********************
* Proprietary MIBs *
********************
Proprietary MIBs are those that have been developed by 
U.S. Robotics to define the managed objects for the devices
that are installed in the chassis.  For example, there is no
approved standard MIB for modems, so U.S. Robotics has defined
a proprietary MIB for its modems.  An example of a managed 
object in this MIB would be the error control setting, 
corresponding to the AT command &Mn.

The following proprietary MIBs, which use ASN.1 structure, 
are supported by the NMC:

MIB Filename    Function
------------    --------
NMC.MIB         Contains NMC-specific information.

DT1.MIB         Contains parameters that affect the hardware
                operation of a T1 Card.

DS0.MIB         Contains parameters that affect the operation
                of each timeslot on a Dual T1 Card.

UDS1.MIB        Contains DS1-specific parameters not supported
                in the standard DS1 MIB.

CHS.MIB         Provides tables that describe the devices in 
                the chassis, and allows the Network Manager to
                take generic actions on cards on the chassis,
                such as resetting a card or downloading software
                to a card.

MDM.MIB         Defines all objects for a USR modem.

CHS_TRAP.MIB    Defines SNMP traps for Fault Management.  
                Must be compiled and integrated in order to use
                traps and alarms, as well as Auto Response.

ANIC.MIB        Contains parameters used for basic management
                of the analog NIC.

PB.MIB          Contains parameters used for configuring Packet
                Bus sessions.

PBDG.MIB        Contains parameters used for monitoring Packet
                Bus performance.

IDS0.MIB        Contains parameters that affect the operation of
                each timeslot on a Primary Rate ISDN Card.

IDT1.MIB        Contains parameters used for basic management of 
                the Primary Rate ISDN Card.

UX25.MIB        Contains parameters used for Packet Level Protocol
                management on the X.25 PAD.

UX25G.MIB       Contains parameters used for basic management of 
                the X.25 PAD Gateway Card.

ULPB.MIB        Contains parameters used for LAPB management on 
                the X.25 PAD. 

UX25W.MIB       Contains parameters used for WAN management on 
                the X.25 PAD.
