Add to an ISDN PRI


The MetaSwitch NE supports only North American variants of ISDN. This means that the ISDN tasks in the EMS can be used only in North America; they do not apply in the UK.

This task allows you to add to an existing ISDN PRI. It applies only to NFAS PRIs; you cannot add a DS1 to a FAS PRI because this type of interface can have only one DS1 associated with it.

At the start of the task, you choose whether to add a primary DS1, secondary DS1, or other DS1 (one that does not carry a D-channel); this determines which subtasks are included in the task.

Enter the following information, and then click on Next to jump to the next step.


Parameter

Description
Add primary ISDN PRI DS1 Choose whether to add a primary DS1 to the interface.
  • If the interface does not already have a primary DS1, you need to use this task to add it before you can use the interface.
  • If the interface already has a primary DS1, the new one becomes primary and the existing DS1 no longer carries a D-channel.
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 the interface already has a secondary DS1, the new one becomes secondary and the existing DS1 no longer carries a D-channel.
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.
