A Media Gateway Entry.
At system power-up, an entry is created by the agent
if the system detects a media gateway module has been added
to the system, and an entry is deleted if the entry associated
media gateway module has been removed from the system.

Each entry represents an signaling protocol supported
by the media gateway.

A Media Gateway IP configuration entry.
Each entry represents a media gateway IP address for MGCs
to communicate with the media gateway.

Each entry represents a domain name used in the system.
Creation and deletion are supported. Modification
is prohibited.

Each entry represents an IP address of the DNS name
server.

An entry of this table is created by the media gateway

cMediaGwTable.

This object is used to represent a domain name under which
the Media Gateway could also be registered in a DNS name
server.
The value of this object reflects the value of
cmgwConfigDomainName from the entry with a value of
'gateway(1)' for object cmgwConfigDomainNameEntity of
cMediaGwDomainNameConfigTable.
If there is no entry in cMediaGwDomainNameConfigTable with
'gateway(1)' of cmgwConfigDomainNameEntity, then
the value of this object will be empty string.

This object represents the entPhysicalIndex of the
card in which media gateway is running. It will contain
value 0 if the entPhysicalIndex value is not available or
not applicable

This object indicates the current service state of the Media
Gateway.
This object is controlled by 'cmgwAdminState'
object.

This object is used to change the service state of
the Media Gateway from inService to outOfService or from

And one PVC only can be associated with one IP address.
If this object is set to zero which means the IP address
is not associated to any interface.

This object represents VPI of the PVC which is associated
to the IP address.
If the IP address is not associated to PVC, the value
of this object is set to -1.

logical-AND of the mask formed from x with the value
of the corresponding instance of the cmgwIpCofigAddress
object is not equal to cmgwIpCofigAddress.

This object specifies cmgwIpConfigAddress of the entry
will become the default gateway address.
This object can be set to 'true' for only one entry in
the table.

These objects can not be modified after the value of this
object is set to 'active'.
Modification can only be done by deleting and re-adding the
entry again.
After the system verify the validity of the data, it
will set the cmgwIpConfigRowStatus to 'active'.

An index that is uniquely identifies a domain name
configured in the system.

This object indicates which entity to use this domain name.

When deleting domain name of DNS name server
(cmgwConfigDomainNameEntity is dnsServer (2)), the
cMediaGwDnsIpConfigTable should be empty.
Adding/deleting entry with cmgwConfigDomainNameEntity
of 'mgc' will cause adding/deleting entry in
cMgcConfigTable (CISCO-MGC-MIB) automatically.
The cmgwConfigDomainName and cmgwConfigDomainNameEntity
can not be modified if the value of this object is
'active'.

This table contains the global media gateway parameters
information.
It supports the modification of the global media gateway
parameters.

This table contains the available signaling protocols that
are supported by the media gateway for communication with
MGCs.

This table contains a list of media gateway IP address and
the IP address associated interface information.
If IP address associated interface is PVC, only
aal5 control PVC or aal5 bearer PVC are valid.
When the PVC is aal5 control, the IP address is used to
communicate to MGC; when the PVC is aal5 bearer, the IP
address is used to communicate to other gateway.
The PVC information is kept in cwAtmChanExtConfigTable:
cwacChanPvcType:      aal5/aal2/aal1
cwacChanApplication:  control/bearer/signaling
If IP address associated interface is not PVC, refer to the
IP addresses associated interface table for the usage
of IP address.

This table provides the domain names which are configured by
users.
The domain names can be used to represent IP addresses
for:
gateway
External DNS name server
MGC (call agent) 

There is only one DNS name server on a gateway
and the domain name of the DNS name server is put on
cMediaGwDomainNameConfigTable with 'dnsServer (2)'.
There could be multi IP addresses are associated with the
DNS name server, this table is used to store these IP
addresses.
If any domain name using external resolution, the last entry
of this table is not allowed to be deleted.

This table is for managing LIF (Logical Interface)
in a media gateway.
LIF is a logical interface which groups the TDM
DSx1s associated with a set of packet resource partitions
(PVCs) in a media gateway.
LIF is used for:
1. VoIP switching
2. VoATM switching 

This table defines general call control attributes for
the media gateway.

The MIB module for managing Trunk Media Gateway.
A Media Gateway is a network element that provides conversion
between the audio signals carried on telephone circuits and
data packets carried over the Internet or over other packet
data networks.
Trunk Media Gateway interface is between the telephone network
and a Voice over IP/ATM network.
The interface on a Trunk Gateway terminates a trunk connected
to PSTN switch (e.g., Class 5, Class 4, etc.).
Media Gateways use a call control architecture where the call
control 'intelligence' is outside the gateways and handled by
external call control elements, called Media Gateway
Controllers (MGCs).
The MGCs or Call Agents, synchronize with each other to
send coherent commands to the gateways under their control.
MGCs use master/slave protocols to command the gateways under
their control.  Examples of these protocols are:
*  Simple Gateway Control Protocol
*  Media Gateway Control Protocol
*  Megaco (H.248)
*  Simple Resource Control Protocol
To connect MG to MGCs using these control protocols through
an IP/UDP Ports which must be configured. To resolve IP
Addresses, DNS name services may be used.
