ISDN Interface

This section explains how to configure the following WAN interfaces:
ISDN Interface
V.92 Modem Interface
Integrated Services Digital Network (ISDN) is a set of standards for digital
transmission over different media created by the Consultative Committee for
International Telegraphy and Telephone (CCITT) and International
Telecommunications Union (ITU). As a dial-on-demand service, it has fast call setup
and low latency as well as the ability to carry high-quality voice, data, and video
transmissions. ISDN is also a circuit-switched service that can be used on both
multipoint and point-to-point connections. ISDN provides a service router with a
multilink Point-to-Point Protocol (PPP) connection for network interfaces. The ISDN
interface is usually configured as the backup interface of the Ethernet interface to
access external networks.
To configure the ISDN interface, use the WebUI or CLI:
WebUI
Network > Interfaces > List > Edit (bri0/0): Enter or select the following, then
click OK:
BRI Mode: Dial Using BRI
Primary Number: 123456
WAN Encapsulation: PPP
PPP Profile: isdnprofile
CLI
set interface bri0/0 dialer-enable
set interface bri0/0 primary-number "123456"
set interface bri0/0 encap ppp
set interface bri0/0 ppp profile isdnprofile
save
To configure the ISDN interface as the backup interface, see "Backup Untrust
Interface Configuration" on page 33.
For more information on how to configure the ISDN interface, refer to the Concepts
& Examples ScreenOS Reference Guide.
