Configure Off-Premises Extension service

This step applies only when configuring a single Individual Line. You cannot configure Off-Premises Extension for multiple Individual Lines at the same time, nor for other subscriber types.

This step is omitted if no call services are selected in the Off-Premises Extension field in the earlier step, Select subscribed services.

This step is optional.

Enter the following information.


Parameter

Description
Access Device The Access Device that the extension line uses to connect to the NE. Click on the ellipsis symbol at the end of the field to choose from access devices on Trunk / Access Gateways or access devices on Subscriber Gateways. Then select from the displayed list of gateways of the specified type, and then select from the displayed list of Access Devices on the specified gateway.
Access Line number The Access Line number on the specified Access Device that this subscriber uses. Either type in the number (which must not match the access line number used by any other subscriber on this access device), or click on the ellipsis symbol at the end of the field to select from the list of numbers not currently in use. The highest line number that you can specify depends on the access device type: for an IAD it is the number of voice ports configured, and for other devices it is a configured parameter on the access device. If you click on the ellipsis symbol, the dialog box that appears offers 'manual selection' or 'automatic selection'.
  • If you select 'automatic selection', the EMS will assign the subscriber the next free access line number for this device.
  • If you select 'manual selection', the following dialog box presents sub-ranges of access line numbers. 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.)
Signal function code The signal function code used for CAS signaling on the extension line. Values:
  • Loop start
  • Ground start
