Dial-up is one of the modules you have to configure in order to use the PPP dial-up over ISDN feature. Also 
consider the check-connectivity command (

) on the IP interface and the interface dialer mode 

(

) in context cs.

Dial-up brings up an IP interface even if the link is not established (spoofing). On some trigger conditions the 
spoofer gives the signal to dial or to drop the connection to dialer that is bound to the IP interface.  There are 
three different trigger conditions available. 

Dial-up on demand
Dial when the first packet is sent out that interface and drop after a certain time where no packet is routed 
through that interface.

Mode: context ip/interface

Configure dial-up on demand. Idle timeout 
specifies the idle time in seconds before drop-
ping connection (Default 300). Queue-limit 
specifies the max. number of packets to 
queue while the link is down (Default 4).
