The IAD object defines an Integrated Access Device connected to the NE.
Each IAD object is a child of the IADs object. Because there may be a large number of IAD objects, the EMS System Explorer displays them in groups underneath the IADs object. Expand the groups to display the range of IAD objects within them. Note that as IAD objects are created and deleted, the allocation of IADs to groups may change.
To configure and use an IAD, you need to do the following:
![]() |
You cannot delete an IAD if an Access Device is associated with it. You cannot deactivate or disable an IAD if an Access Device associated with it is active or enabled. |
Object-Specific Actions | |
Reconfigure | To reconfigure the IAD to the default configuration, click on the Reconfigure pushbutton. |
OAM loopback | To perform an OAM loopback test on the IAD, click on the OAM loopback pushbutton. This pushbutton is active only when the requested status is Active. |
Parameter |
Access |
Description |
Access Device number | Create | A unique number to identify this device, which must not match the number of any other access device. Either type in the number to use, or click on the ellipsis symbol at the end of the field to choose the first free access device number. |
Port name | Read only | A unique identifier for this device among all other devices on the Media Gateway. This identifier is used by child objects of the Call Agent that need to reference this device. |
Description | Change | A text string used in the EMS System Explorer to identify this IAD. Specify a string of up to 40 characters. |
Customer information | Change | A text field that can be used to store information about the IAD, for example the address of the customer associated with it. This field is optional; you can supply up to 64 characters of free-form text. The text wraps to the width of the field on screen, or you can use the Enter key to force linebreaks. The total contents of all six Customer information fields must not exceed 164 characters. |
Customer information 2 | Change | A text field that can be used to store additional information about the IAD. This field is optional; you can supply up to 32 characters of free-form text. The total contents of all six Customer information fields must not exceed 164 characters. |
Customer information 3 | Change | A text field that can be used to store additional information about the IAD. This field is optional; you can supply up to 32 characters of free-form text. The total contents of all six Customer information fields must not exceed 164 characters. |
Customer information 4 | Change | A text field that can be used to store additional information about the IAD. This field is optional; you can supply up to 32 characters of free-form text. The total contents of all six Customer information fields must not exceed 164 characters. |
Customer information 5 | Change | A text field that can be used to store additional information about the IAD. This field is optional; you can supply up to 32 characters of free-form text. The total contents of all six Customer information fields must not exceed 164 characters. |
Customer information 6 | Change | A text field that can be used to store additional information about the IAD. This field is optional; you can supply up to 32 characters of free-form text. The total contents of all six Customer information fields must not exceed 164 characters. |
Number of voice ports to configure | Change Inactive | Number of voice ports to be configured on this IAD. This is not necessarily the same as the number of voice ports supported on the IAD. If the number of voice ports supported on the IAD is less than this value, the voice ports that cannot be supported are alarmed. During creation, when this field is set, the system automatically creates the configured number of IAD Voice Port objects, which exist until the IAD Port is destroyed. If this field is later modified, the system creates or deletes IAD Voice Port objects correspondingly. |
Maximum concurrent calls allowed | Change Inactive | Maximum number of calls that can be in progress at any one time on the IAD. This value allows you to restrict the amount of bandwidth used on the VCC to the IAD, on the assumption that not all voice ports on the IAD will need to be in use at the same time. This count includes both ADPCM (G.726) and PCM (G.711) calls. For the purposes of this count, if a tone (such as the reorder tone) is being played to a subscriber outside of a call, the subscriber is viewed as being in a call for the duration of the tone. If a call setup attempt is made to or from the IAD after this count has been reached, the call setup attempt will be rejected. This value cannot exceed the value of Number of voice ports to configure for this IAD. Changing this value will change the value of the Required sustained cell rate parameter; you should update the ATM switch configuration for the appropriate VCC to reflect this. In addition, changing this value may require the value on the IAD group for this IAD to be updated. |
Maximum concurrent PCM calls allowed | Change Inactive | Maximum number of PCM (G.711) calls that can be in progress at any one time on the IAD. This value allows you to restrict the amount of bandwidth used on the VCC to the IAD, on the assumption that not all voice ports on the IAD will need to be in use at the same time. For the purposes of this count, if a tone (such as the reorder tone) is being played to a subscriber outside of a call, the subscriber is viewed as being in a call for the duration of the tone. If a PCM call setup attempt is made to or from the IAD after this count has been reached, the call setup attempt will be rejected. This value cannot exceed the value of Maximum concurrent calls allowed for this IAD. If the IAD supports only PCM and not ADPCM (AAL2 channel profile is set to Profile 9), the two values should be the same. Changing this value will change the value of the Required sustained cell rate parameter; you should update the ATM switch configuration for the appropriate VCC to reflect this. In addition, changing this value may require the value on the IAD group for this IAD to be updated. |
Required sustained cell rate | Read only | The sustained cell rate required to support calls on this IAD. This is calculated from the values for Maximum concurrent calls allowed and Maximum concurrent PCM calls allowed. Ensure that the ATM switch configuration for the appropriate VCC matches this value, as follows:
|
Cell delay variation | Change Inactive | The cell delay variation in milliseconds for terminations using this IAD. This value is used to help cancel out variation in the arrival rate of voice data cells from the IAD. (This variation is also known as jitter.) Larger values may improve quality, especially for modem and fax, but will add a small delay to the voice data received from the IAD. Note that increasing this value allocates extra resources on the ATM adaptor and frequent use of values greater than 16ms may reduce the total concurrent call capacity. Range: 1 - 60. The default is 11. |
IAD Group | Change Inactive | The IAD Group to which this IAD belongs. Select from the list of configured IAD Groups. |
ATM Port name | Change Inactive | The Fault Tolerant ATM Port (VP3500 or MG3500) or ATM Port (VP3510 or MG3510) that this IAD is connected to. Select from the displayed list of Fault Tolerant ATM Ports or ATM Ports. (You cannot select an ATM Port on a PB4000 that is configured as a backup adaptor for EPS; these will not be shown in the list.) Note that the ranges of valid values for the VPI, VCI and Base channel ID depend on the ATM Port selected. (For a VP3500 or MG3500, both ATM Ports associated with the Fault Tolerant ATM Port should have the same VPI and VCI ranges.) If you change this field such that the values previously set for VPI, VCI and Base channel ID are not within the ranges for the new ATM Port, the values in these fields are automatically deleted and you must specify new values. |
VPI | Change Inactive | The VPI of the PVC used by this IAD to access the NE. This must be within the VPI range defined for the ATM Port selected. |
VCI | Change Inactive | The VCI of the PVC used by this IAD to access the NE. This must be within the VCI range defined for the ATM Port selected. |
Base channel ID | Change Inactive | Identifies the channel ID of the base AAL2 channel. The AAL2 channel used for a particular voice port on an IAD is the base AAL2 channel plus the voice port ID. This must be within the range defined for the ATM Port selected. Range: 16 - 127. |
AAL2 channel profile | Change Inactive | Specifies which AAL2 profile is used for AAL2 channels used by this IAD. Values:
|
Deactivation mode | Change | Specifies how child objects should be deactivated when deactivating this object. Values:
|
OAM loopback test status | Read only | Status of the last OAM loopback test that was requested by clicking on the OAM loopback pushbutton. Values:
|
Alarm state | Read only | Specifies whether any alarms are currently raised for the IAD. Values:
|
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 the alarm count was reset) that this object's alarm state has gone to Attention Required. |
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 the alarm count was reset) that this object's alarm state has gone to Attend To Dependent. |
Alarm state changed timestamp | Read only | The time at which the Alarm state last changed. |
Alarm events reset timestamp | Read only | The time at which the alarm count was last reset to zero. |
Diagnostics - logging - log level | Change | Specifies the level of logs recorded for this object. Logs with a priority equal to or greater than the priority specified are recorded. Set to Default level to use the system-wide default level. Values:
|
Diagnostics - API trace - enabled | Change | Specifies whether API tracing is enabled for this object. Values:
|
Diagnostics - API trace - trace tag | Change | An optional text string inserted into API tracing and PD logging for this object. (This string can include accented / international characters as defined in ISO 8859-1.) If you want to filter on this tag in the craft interface, do not include spaces or any of the characters ^ \ $ * + ? | ( ) , . ' ' " [ ] { }. |
Export - number of objects exported | Read only | The total number of objects (including child objects) written to the export file so far in the current or most recent export operation. |
Export - status | Read only | The status of the current or most recent export operation, if any. Values:
|
Export - file | Change | The name of the text file (in the EMS User's home directory on the EMS Server) to which configuration information for this object will be exported. The maximum length of the filename is 32 characters. |
Export - log correlator | Read only | If the export status is Failed, this field contains a correlator for the log message that contains details of the failure. Click on the 'go to log' button next to this field to jump to this message in the EMS log viewer window. |
Export - correlator metaswitch | Read only | If the export status is Failed, this field contains the name of the EMS Server or MetaSwitch Network Element that generated the failure log. You may need this information to find the log in the EMS log viewer window. |
Requested status | Read only | Specifies whether an administrator has attempted to activate the IAD. Values:
|
Actual status | Read only | Specifies the current status of the IAD. Values:
