Configure subscriber connection information

This step is mandatory if you are adding a new PBX Line and the Number status of the parent PBX is set to Normal, Ported to, or Non-geographic. Otherwise there are no fields to fill in and you can ignore this step.

Enter the following information.


Parameter

Description
Configured SIP Binding This field appears only if the Call Agent signaling type field on the PBX object is set to SIP. Specifies the configured SIP binding that this PBX Line uses to connect to the NE. To specify a configured SIP binding, click on the ellipsis symbol at the end of the field to select from a list of configured SIP bindings for which the Usage field is set to Subscriber.
Access Device This field appears only if the Number status field on the PBX object is set to Normal, Ported to, or Non-geographic and the Call Agent signaling type field on the PBX object is set to Analog line/T1 CAS. The Access Device that this line uses to connect to the NE. If the task you are using has already added access hardware and is now adding a new subscriber to use this hardware, this field is read-only. Click on the ellipsis symbol at the end of the field to choose whether this device is on a Trunk/Access Gateway or on a Subscriber Gateway. Then choose the gateway, and finally the access device.
Access Line number This field appears only if the Number status field on the PBX object is set to Normal, Ported to, or Non-geographic and the Call Agent signaling type field on the PBX object is set to Analog line/T1 CAS. The Access Line number on the specified Access Device that this line 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, for an IDT Port it is 2048, 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.)
ISDN Interface The ISDN Primary Rate Interface that this subscriber uses to connect to the NE. This field appears, and must be supplied, only if the Call Agent signaling type field on the PBX object is set to ISDN PRI. Select from the displayed list of ISDN Primary Rate Interfaces that have Usage set to Access (trunk PRIs cannot be used for subscriber access). Each PBX Line corresponds to its own ISDN PRI (which can support multiple concurrent telephone calls); you cannot configure two PBX Lines using the same ISDN PRI. If the task you are using has already added access hardware and is now adding a new subscriber to use this hardware, this field is read-only.
