Configuring ISDN BRI Lines
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.
The ordering process varies from provider to provider and from country to
country; however, here are some general guidelines:
• Ask for two channels to be called by one number.
• Ask for delivery of calling line identification, also known as caller ID or
Automatic Number Identification (ANI).
ISDN BRI Provisioning by Switch Type
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.
Table 5-4 lists the provisioning you should order for your Catalyst 4224 for each
switch type.
