Configuring the PRI Network Interface
To use the PRI network interface, you must configure the following:
• PRI network support
• PRI channels

Your ISDN service provider can tell you which protocol your network uses. If
you later change the Country setting, the PRI switch protocols available may
also change, and you may be prompted to configure a different PRI switch
protocol.
To configure the ISDN network interface settings:
1. Go to System > Admin Settings > Network > ISDN.
2. Configure these settings:
Points to note about fractional PRI:
•
Assigned channels must begin with channel 1, and the channel numbers must
be consecutive.
• A D channel must be provided.
• Outbound call bandwidth must not exceed the available bandwidth.
