PPP Dial-up over ISDN

The following modules in this section must be configured in order to use the PPP dial-up over ISDN feature:
• PPP Dialer (see page
• Dial-up (see page 335)
• IP Link Supervision (see

PPP Dialer

The PPP Dialer is one of the modules you have to configure in order to use the PPP dial-up over ISDN fea-
ture. Also, consider the dial-up command
IP interface.
The dialer is responsible for establishing and tearing down call-signaling connections to the remote-access
server. The dialer is a virtual interface of the circuit-switching (CS) context. Thus the dialer belongs to the
domain of switch-circuit connectivity even if the established link finally runs the IP protocol.
To establish a connection, the dialer must be triggered by an external source, for example, a spoofing IP inter-
face (an IP interface configured for dial-up). Whether this trigger is fired on the first packet sent over that IP
interface or if the primary link to the destination goes down, is configured using the dial-up command on
bound IP interface.
When the dialer receives the trigger event it tries to establish one or more connections to the configured desti-
nation. You can specify a list of destinations to be tried. Each destination configuration contains all informa-
tion needed to dial and log in to a certain remote-access server (i.e. remote party number, login credentials,
PPP parameters, etc.). However some of the parameters are indirectly configured using a PPP subscriber con-
figuration entity.
The following configuration parameters are the same for all destinations:
• Recovery Strategy: If and when a retry is started after a failed dial attempt.
• Destinations: A list of destinations, each of which contains the parameters below.
The following configuration parameters can be configured for each destination separately:
• Local and Remote Party Number: Calling- and Called-E.164 number for the signaling connection.
• Call Route: A link to a call-router element, for example an ISDN interface. This route defines over which
interface the dial-up call is placed. Instead of routing a call directly to an ISDN interface, you can also route
the call to a hunt-group service that hunts for a free B-channel over multiple BRI interfaces.
