6. If the call mode does not include originate, the router must wait to
receive a call from the other end of the line. Either contact the remote site
and have it initiate a connection or change the setting so the local router
can place a call.
7. If the call mode includes originate, verify that backup is enabled at this
time.
8. If backup is enabled, check the backup dial list (also displayed with show
backup int). This list may be blank if, for example, you have changed a
Frame Relay subinterface's Data Link Connection Identifier (DLCI).
9. If the dial backup list does not contain at least one number and backup
interface, configure the list. Make sure that the number is that for the
remote site.
10. If the dial backup list has been configured, note the backup interface
specified in the dial backup list. View the status or running-config for this
interface (show int ppp 2 or show run int ppp 2) and verify that the
interface has been configured and activated.
The Call Does Not Connect. See Table 3-18 for a summary of possible
causes for a call failing to connect.

When a call from the local router to the peer fails, follow these steps:
1. A "Connect failed (BUSY)" often indicates a problem at the other end of
the connection. The peer's backup interface may by down. The peer may
also be rejecting your call. Contact the remote site and find the problem.
You should also double-check that the telephone number on the local
router's backup interface matches that accepted by the peer router.
Possible Problems
• • The number configured in the backup dial list is not the
peer's correct number.
• The backup call has collided with the peer's call.
• The peer refuses to or cannot answer the call.
There is a problem between the local interface and the
CO's switch.
The number configured in the backup dial list is not a valid
number.
