The Multiple Appearance Directory Number (MADN) object defines an external number that can be used to access multiple lines within a Business Group, so that all free lines associated with the MADN ring when the number is dialed. It is a child of the Multiple Appearance Directory Numbers object.
A MADN has up to 32 MADN Member child objects, each corresponding to a Business Group Line that rings when the number is dialed.
To configure and enable a MADN, you need to do the following:
When you first enable the MADN, most of the subscriber services are disabled by default, except for a small number that can be enabled by default in the global Call Services configuration. You can then activate individual services for the MADN as required.

Access |
Description |
Pilot directory number | Create | The 10-digit directory number that an external caller dials to access the MADN. Either type in the number (noting that the directory number must be within the parent Business Group Number Block if you set the Number status to Normal, Ported from, or Non-geographic), or click on the ellipsis symbol at the end of the field to select from the list of numbers not currently in use. If you click on the ellipsis symbol, the dialog box that appears presents sub-ranges from the parent Business Group Number Block. Select the sub-range from which the number should be taken and click on Next. In the next dialog box, select a number and click on OK to accept this number. (If no number is shown, this indicates that there are no free numbers in the range; click on Back and select a different number range.) |
Charge number | Change Inactive | The 10-digit directory number to which calls are billed, which can be different from the directory number if required. If this field is left blank, calls are billed to the subscriber's directory number. |
Calling party number | Change Inactive | The 10-digit directory number, if any, to be sent in signaling messages for this subscriber in place of the subscriber's directory number (for example, if the directory number corresponds to an outgoing-only line and should be replaced by the number of another line that accepts incoming calls). |
Persistent Profile | Change | The Persistent Profile that is used as a basis for the configuration of this MADN and its call services. The default values for many other fields in the MADN's configuration are taken from the selected profile. Select from the list of Persistent Profiles that are configured for use by MADNs, or select Persistent Profile "None" to use the system defaults instead of using a profile. |
Call limit algorithm | Change | Specifies how the NE should limit the total number of concurrent incoming calls to the MADN. When this limit is reached, any further incoming call attempts will receive a busy indication. Note that an incoming call to the MADN counts against this limit only if it is connected to a Business Group Line that is a direct child object of the MADN; calls connected to another MADN or MLHG that is a child of the called MADN are not counted.
Choose Use default or specify a value:
|
Call limit value | Change | This field appears only if Call limit algorithm is set to Total calls cannot exceed specified value or Queued calls cannot exceed specified value. Choose Use default or specify the maximum total number of incoming calls (minimum 1) or the maximum number of queued calls (zero indicates that calls will never be queued). |
Intercom dialing code | Read only | If the MADN's directory number is included within an Intercom Code Range defined for this Business Group, this field shows the intercom code that subscribers within the group can use to call the MADN. |
Number status | Change Inactive | Specifies the status of this number. Values:
|
Recently moved from old number | Change Inactive | Specifies whether this subscriber has recently moved to this directory number from a different number. This field appears only if Number status is set to Normal, Ported to, or Non-geographic. Values:
|
Moved from directory number | Change | The old directory number from which this subscriber has moved. This field appears only if Recently moved from old number is set to True. Specify the number as a 10-digit directory number. |
Connect call after announcement | Change Inactive | This field appears only if Number status is set to Recently moved. Specifies whether a caller who calls the old number should be connected to the new number after an announcement. Values:
|
Moved to directory number | Change Inactive | The new directory number to which this subscriber has now moved. This field appears only if Number status is set to Recently moved, and is required if Connect call after announcement is set to True. Specify the number as a 10-digit directory number. |
Ported exchange ID | Change Inactive | This field appears, and must be supplied, only if the Number status field is set to Ported from. This field is valid only in the UK. |
PIN | Change | The personal identification number (PIN) that this subscriber should use to access services related to their phone line. This field appears only if Number status is set to Normal, Ported to, or Non-geographic. You must specify a valid PIN before the subscriber can access any services that require a PIN. Specify a 4-digit number. |
Force LNP lookup | Change | This field is used to force an LNP lookup for a particular subscriber. This is typically only used when a ported subscriber is moving. During the period where the subscriber number is configured as active on two switches, the number portability database is the definitive reference for which number is active.
The typical sequence used for porting a subscriber is as follows.
|
Enabled date | Read only | The date and time at which this object was enabled in the EMS. |
Child Call Service Attention Required alarms | Read only | The total number of Call Service children of this object that are in Attention Required state. |
Child Call Service Attention Required alarm events | Read only / Reset | The total number of times that the alarm state for a Call Service child object has gone to Attention Required. |
Child Call Service Attend To Dependent alarms | Read only | The total number of Call Service children of this object that are in Attend To Dependent state. |
Child Call Service Attend To Dependent alarm events | Read only / Reset | The total number of times that the alarm state for a Call Service child object has gone to Attend To Dependent. |
Summary child alarm state | Read only | Summarizes the alarm status for all children of this object. Values:
|
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 diagnostics tag inserted into API tracing and PD logging for this object. This tag may include any ASCII characters. |
Diagnostics - API trace - trace remote number | Change | The remote directory number that should be API traced. Outgoing calls made to this number or incoming calls received from this number should be API traced. If a directory number is not specified, all calls made by and received by this subscriber will be API traced. |
Requested status | Read only | Specifies whether an administrator has attempted to enable the MADN. Values:
|
Actual status | Read only | Specifies the current status of the MADN. Values:
