This section describes how to configure the interfaces on the basic rate interface
(BRI) card of your Catalyst 4224.
Before using a Catalyst 4224 with an ISDN BRI interface, you must order a
correctly configured ISDN BRI line from your local telecommunications
service provider. ISDN BRI provisioning refers to the types of services
provided by the ISDN BRI line. Although provisioning is performed by your
ISDN BRI service provider, you must tell the provider what you want.
Before you begin, disconnect all WAN cables from the Catalyst 4224 to keep
it from running the AutoInstall process. The Catalyst 4224 attempts to run
AutoInstall if there is a WAN connection on both ends and the Catalyst 4224
does not have a valid configuration file stored in NVRAM. The Catalyst 4224
can take several minutes to determine that AutoInstall is not connected to a
remote TCP/IP host.
