Add a new ISDN PRI


In the Tasks interface, you can add ISDN PRI DS1s that use media on MetaSwitch Media Gateways, but not those that use media on third-party media gateways. You can add ISDN PRI DS1s that use media on third-party media gateways using the object tree in the EMS System Explorer.

This task allows you to add a new ISDN PRI, together with a DS1 (or multiple DS1s if it is an NFAS interface).

Enter the following information.


Parameter

Description
ISDN Interface type Choose whether the new interface will be an NFAS (Non Facility Associated Signaling) interface. This supports multiple T1 connections with their signaling information sharing the same D-channel, for increased interface capacity. Values:
  • NFAS
  • FAS
If you select FAS, the following fields relating to adding primary and secondary DS1s to the interface are hidden, because a FAS interface can have only one DS1 associated with it.
Add primary ISDN PRI DS1 Choose whether to add a primary DS1 to the interface. This option is selected by default. If you do not add the primary DS1, you will need to use the Add to an ISDN PRI task to add it later before you can use the interface.
Add secondary ISDN PRI DS1 Choose whether to add a secondary DS1 to the interface, to provide a backup D-channel if the primary channel fails. If you do not add the secondary DS1, you can use the Add to an ISDN PRI task to add it later.
Add other ISDN PRI DS1 Choose whether to add a DS1 without a D-channel to the interface.
Add additional ISDN PRI DS1s This field appears only if you chose to add a DS1 without a D-channel. Choose whether you want to add more DS1s after you have added the first one.

For each step, complete the required fields and press Next to continue to the next step. Note that any fields in bold text are mandatory and you will not be able to move to the next step until these fields are completed (the Next pushbutton will be inactive).

When a step is not mandatory, you do not need to enter any information, you can just click on Next to jump to the next step. When all mandatory steps (excluding the confirmation step) have been completed, you can click on Finish to jump straight to the final step (the confirmation step). At the final step, click on Confirm to accept the configuration entered in the previous steps of this task.
