CISCO-MEDIA-GATEWAY-MIB: View SNMP OID List / Download MIB

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.

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

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.

An index that uniquely identifies an entry in the 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 outOfService to inService. The resulting service state of the gateway is represented by 'cmgwServiceState'.

This object is used to represent grace period. The grace period (restart delay in RSIP message) is expressed in a number of seconds. It means how soon the gateway will be taken out of service. The value -1 indicates that the grace period time is disabled.

This object is used to represent the VT (sonet Virtual Tributary) counting. standard - standard counting (based on Bellcore TR253) titan - TITAN5500 counting (based on Tellabs TITAN 5500) Note: 'titan' is valid only if sonet line medium type (sonetMediumType of SONET-MIB) is 'sonet' and sonet path payload type (cspSonetPathPayload of CISCO-SONET-MIB) is 'vt15vc11'. Enumeration: 'titan': 2, 'standard': 1.

This object is used to enable or disable the source IP and port filtering with MGC for security consideration as follows: 'true' - source IP and port filter is enabled 'false' - source IP and port filter is disable

This object is used to enable or disable the lawful intercept for government. as follows: 'true' - enable lawful intercept 'false' - disable lawful intercept

This object is to enable or disable V23 tone. Setting the object value to 'true', will cause VXSM (Voice Switching Service Module) to detect V23 tone.

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

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

An index that uniquely identifies an entry in cmgwSignalProtocolTable.

This object is used to represent the protocol type. other - None of the following types. mgcp - Media Gateway Control Protocol h248 - Media Gateway Control (ITU H.248) tgcp - Trunking Gateway Control Protocol Enumeration: 'tgcp': 4, 'h248': 3, 'other': 1, 'mgcp': 2.

This object is used to represent the protocol version. For example cmgwSignalProtocol is 'mgcp(2)' and this object is string '1.0'. cmgwSignalProtocol is 'h248(3)' and this object is set to '2.0'.

This object is used to represent the UDP port associated with the protocol. If the value of cmgwSignalProtocol is 'mgcp(2)' and the value of cmgwSignalProtcolVersion is '1.0', the default value of this object is '2727'. If the value of cmgwSignalProtocol is 'h248(3)' and the value of cmgwSignalProtcolVersion is '1.0', the default value of this object is '2944'.

This object specifies the protocol port of the Media Gateway Controller (MGC). If the value of cmgwSignalProtocol is 'mgcp(2)' or 'tgcp(4)' and the value of cmgwSignalProtcolVersion is '1.0', the default value of this object is '2427'. If the value of cmgwSignalProtocol is 'h248(3)' and the value of cmgwSignalProtcolVersion is '1.0', the default value of this object is '2944'.

This object specifies the preference of the signal protocol supported in the media gateway. If this object is set to 0, the corresponding signal protocol will not be used by the gateway. The value of this object is unique within the corresponding gateway. The entry with lower value has higher preference.

This object specifies the protocol version used by the gateway in the messages to MGC in order to exchange the service capabilities. For example cmgwSignalProtocol is 'h248(3)' and this object can be string '1' or '1.0', '2' or '2.0'. 'MAX' is a special string indicating the gateway will use the highest protocol version supported in the gateway, but it can be changed to lower version after it negotiates with MGC. The final negotiated protocol version will be indicated in cmgwSignalProtocolVersion. The version strings other than 'MAX' can be specified for the gateway to communicate with the MGC which doesn't support service capabilities negotiation. For example if a MGC supports only version 1.0 MGCP, this object should be set to '1' to instruct the gateway using MGCP version 1.0 format messages to communicate with MGC.

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.
