Configuring an ISDN Interface
Before creating a pool with ISDN lines, you need to select a port and designate it
as a BRI or PRI interface. Refer to the appropriate section for instructions:
• Configuring BRI Lines
on page 3-12
• Configuring PRI Lines on page 3-14
Configuring BRI Lines
ISDN/BRI net modules are available only on the Access Node (AN), Access
Stack Node (ASN), Access Node Hub (ANH), Advanced Remote Node (ARN),
and System 5000™ platforms.
To configure BRI interfaces, you specify the interface for BRI service and the type
of service, for example, whether one or two B channels are available.
To configure a BRI object:
1.
Create the BRI interface by entering:
bri
<
slot/connector
>
mode
<
mode_type
>
mode_type
specifies whether the BRI line is operating as a dial-up line or as a
leased line. Table 3-2
lists the modes.
When choosing a mode, follow these guidelines:
• If you have a dial-up application, choose one of the dial-up modes.
• For networks in Germany and Japan, you can configure a permanent
point-to-point ISDN connection over a B channel, without having to use
the D channel to dial the call. This connection operates like a leased line.
To configure leased BRI connections, select one of the leased modes.
Note that for leased BRI applications, your ISDN switch must be able to
support these connections.
