Processing connect-sequences
1. Check connect-order.
connect-order sequential
3. Check connect-mode. Can the
interface answer or originate a call?
connect-mode either
5. Was the call for connect-sequence
20 successful?
Yes = PPP session begins
No = process connect-sequence 10
up to two more times or until a call is
successful
7. If the demand interface
cannot successfully establish
a call, the router puts it into the
recovery state.

2. Process connect-sequence 2,
based on connect-order.
connect-sequence 10 dial-string 5551212
forced-ISDN-64k busyout-threshold 3
connect-sequence 20 dial-string 5552222
forced-analog busyout-threshold 1
4. Was the call successful?
Yes = PPP session begins
No = process connect-sequence 20
6. Based on connect-
sequence attempts command,
repeat steps 2 through 5 until
a call is successful or a
maximum of two more times.
connect-sequence attempts 3
8. In the recovery state, the demand
interface attempts to establish a
connection every 60 seconds.
Based on the configuration, it tries
a maximum of five times. If the
demand interface is not successful,
its status changes to down.
