The Media Gateway object provides an overall view of the NE's hardware. This object is pre-configured (configuration information is delivered with the NE), and you cannot create or delete it, but it provides status information about the hardware.
The Media Gateway object is a child of the MetaSwitch object.
Parameter |
Access |
Description |
Call Agent IP address | Read only | The IP address of the Call Agent associated with this Media Gateway. This is configured through the NE craft interface, as described in the IS, CA and MG Craft Interface Guide. |
Call Agent name | Read only | The name of the Call Agent associated with this Media Gateway. This name is displayed only when the Media Gateway has successfully established contact with the Call Agent and can determine its name. |
TDM Protection Switching mechanism | Change | This field appears only for a VP3500 or MG3500. Specifies whether the NE uses the EPS3500 protection switching mechanism to provide backup for TDM links. Values:
|
Required clock stratum | Change | Specifies the clock stratum at which the NE must operate in order to work correctly with the rest of the network. Values:
|
Clock mastering card type | Read only | This field appears only for a VP2510 or MG2510. Specifies whether the NE uses SG* Signaling Adaptors or PB3100 Adaptors for clock masters. Values:
|
Packetization interval for internal RTP connections | Change | Specifies the intervals at which data on RTP connections internal to the switch is divided into packets. Values:
|
Primary clock master | Read only | The card type, controller, and slot number of the SG* or PB3100 adaptor acting as the primary master of the clocking. |
Primary clock master - stratum | Read only | The clock stratum at which the primary clock master is currently operating. Values:
|
Primary clock master - status | Read only | The status of the primary clock master. This field does not appear if Primary clock master - stratum is set to None. Values:
|
Primary clock master - end of range alarm | Read only | This field does not appear for a VP2510 or MG2510 if your Clock mastering card type is set to PB Family.
Specifies whether the primary clock master is reporting an End of Range (EOR) alarm. This field does not appear if Primary clock master - stratum is set to None.
This alarm occurs when the clock master is locked on to a reference source, but at a frequency at the end of its accessible range; this may indicate a network problem or a hardware error on the adaptor. Values:
|
Secondary clock master | Read only | The card type, controller, and slot number of the SG* or PB3100 adaptor acting as the secondary master of the clocking. In a VP3500 or MG3500, this card cannot be on the same shelf as the primary clock master; if one shelf does not contain an active SG* adaptor, there will be no secondary clock master. |
Secondary clock master - stratum | Read only | The clock stratum at which the primary clock master is currently operating. Values:
|
Secondary clock master - status | Read only | The status of the secondary clock master. This field does not appear if Secondary clock master - stratum is set to None. Values are the same as for Primary clock master - status above. |
Secondary clock master - end of range alarm | Read only | This field does not appear for a VP2510 or MG2510 if your Clock mastering card type is set to PB Family.
Specifies whether the secondary clock master is reporting an End of Range (EOR) alarm. This field does not appear if Secondary clock master - stratum is set to None.
This alarm occurs when the clock master is locked on to a reference source, but at a frequency at the end of its accessible range; this may indicate a network problem or a hardware error on the adaptor. Values:
|
Clock reference 1 | Read only | The port providing the external clocking source for the first clock reference. |
Clock reference 1 - status | Read only | The status of the first clock reference. Values:
|
Clock reference 2 | Read only | The port providing the external clocking source for the second clock reference. In a VP3500 or MG3500 this cannot be on the same shelf as clock reference 1, unless the primary clock master and clock reference 1 are on the same SG* adaptor. To ensure that separate clock references 1 and 2 can be set up, you are recommended to ensure that at least one port on each shelf is configured as a clock reference. |
Clock reference 2 - status | Read only | The status of the second clock reference. Values:
|
Congestion - system load | Read only | The congestion level of the media gateway. This is typically around 10% in normal conditions. A higher value means that the media gateway is overloaded (in terms of its capacity to set up and tear down calls). 100% indicates the gateway's maximum tolerated level of overload; when the gateway reaches this level, the Call Agent can no longer use it to set up any new calls. |
Congestion - RTP resources | Read only | The congestion level of the media gateway's RTP resources, expressed as a percentage of its total capacity. A sudden jump in this value may indicate that a piece of hardware has failed or has been deactivated. |
Alarm state | Read only | Specifies whether any alarms are currently raised for this object. Values:
|
Alarm state changed timestamp | Read only | The time at which the Alarm state last changed. |
Alarm log correlator - Attention Required | Read only | Identifier of the log message for the event that caused the last Attention Required alarm state for this object. This field is reset when the Attention Required alarm events field is reset to zero. |
Attention Required alarm events | Read only / Reset | Number of times (since this field was reset) that this object's alarm state has gone to Attention Required. |
Attention Required alarm events reset timestamp | Read only | The time at which the Attention Required alarm events was last reset to zero. |
Alarm log correlator - Attend To Dependent | Read only | Identifier of the log message for the event that caused the last Attend To Dependent alarm state for this object. This field is reset when the Attend To Dependent alarm events field is reset to zero. |
Attend To Dependent alarm events | Read only / Reset | Number of times (since this field was reset) that this object's alarm state has gone to Attend To Dependent. |
Attend To Dependent alarm events reset timestamp | Read only | The time at which the Attend To Dependent alarm events was last reset to zero. |
