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 a new ISDN PRI, and also to add a PBX with one PBX Line that uses this ISDN PRI. Each ISDN PRI corresponds to a single PBX Line but can support multiple concurrent calls, so you may only need one PBX Line for an ISDN-connected PBX. If you need to add an additional PBX Line to the PBX, this line must use a separate ISDN PRI; you can add it by using the Add a new ISDN PRI task to add the PRI, followed by the Add to a PBX task to add a new PBX Line to the PBX and assign it to the new PRI.
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:
|
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. |
Subscriber template | The subscriber template that the new subscribers will use. Select from the list of subscriber templates. |
Call services template | The call services template that the new subscribers will use. Select from the list of call services templates. |
