Before you configure ISDN interfaces, you need to perform the
following tasks:
Install J-series device hardware. For more
information, see the J-series Services Routers Hardware Guide.
Establish basic connectivity. For more information, see
the Getting Started Guide for your device.
Order an ISDN line from your telecommunications service
provider. Contact your service provider for more information.
If you do not already have a basic understanding of physical
and logical interfaces and Juniper Networks interface conventions,
read Interfaces Overview.
Although it is not a requirement, you might also want to plan
how you are going to use the ISDN interfaces on your network before
you begin configuring them. (To display a list of installed ISDN BRI
interfaces, select Configuration>Quick Configuration>Interfaces.)
