# Remote Directory Numbers

## Purpose

The Remote Directory Numbers form lists the remote portable directory numbers in a cluster network that is configured with the portable directory number feature. Remote portable directory numbers belong to devices that are hosted by remote cluster elements. In relation to the network element that you are programming, all other elements in the cluster network are remote elements.

## Conditions

- This form is read-only if Remote Directory Number Synchronization is enabled for the cluster.

- For resiliency, SIP devices must be identified by directory number to both the primary and secondary controllers.

- A remote directory telephone number cannot translate into a programmed local directory number.

- To keep resilient directory entries in this form synchronized between primary and secondary controllers, enable the System Data Synchronization feature.

CAUTION: Do not make changes directly to this form. The only exception to this rule is if there are inconsistent Remote Directory Numbers (RDNs) or mismatched device types in databases of the primary and secondary controllers. In this case, you use this form to delete the inconsistent RDNs from all the elements in the cluster except for the primary controller.

## Field Descriptions

Parameter | Description | Default Value
Number | Enter 1 to 7 digits (* and # are allowed) to assign the directory number of a remote cluster element device. This field is read-only if Remote Directory Number Synchronization is enabled for the cluster. | Blank
Cluster Element Index | Enter the 1 to 3-digit CEID index number. This number must be in the range of 1 to 999. The default is blank. You must assign a CEID index in the Cluster Elements form before you can enter it in this form. This field is read-only if Remote Directory Number Synchronization is enabled for the cluster. | Blank
Secondary Cluster Element Index | Enter the 1 to 3-digit CEID index number of the secondary ICP. This number must be in the range of 1 to 999. The default is blank. You must assign a CEID index in the Cluster Elements form before you can enter it in this form. NOTE: This field is read-only if Remote Directory Number Synchronization is enabled for the cluster. | Blank
Name | System-generated, protected field. Gives the name corresponding to the directory number as entered in the telephone directory. If no name is programmed in Telephone Directory for the remote directory number, this field is blank. This field accepts a maximum of 21 characters. |
