ISDN 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 as follows:

WebUI

Network > Interfaces > List > Edit (bri1/0): 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 bri1/0 dialer-enable

set interface bri1/0 primary-number "123456" set interface bri1/0 encap ppp

set interface bri1/0 ppp profile isdnprofile save

To configure the ISDN interface as the backup interface, see “Backup Untrust

Interface Configuration” on page 37.

For more information on how to configure the ISDN interface, refer to the Concepts & Examples ScreenOS Reference Guide.

T1 Interface

The T1 interface is a basic Physical Layer protocol used by the Digital Signal level 1 (DS-1) multiplexing method in North America. A T1 interface operates at a bit-rate of 1.544 Mbps or speeds up to 24 DS0 channels.

The devices support the following T1 DS-1 standards:

„ANSI TI.107, TI.102

„GR 499-core, GR 253-core
