The configuration requirements for dedicated PVC management are identical to those listed for shared PVC management. See the previous section, Minimum Configuration Requirements for Shared PVC Management, for more information.

DIAL BACKUP APPLICATION

The IQ Probe dial backup (DBU) options allow frame relay circuit outage recovery for one user to network interface (UNI) at a time. Therefore, if the host site goes down, only one remote site (the primary remote) is backed up. The IQ Probe can be configured to originate a call based on physical layer conditions and/or PVC signaling loss. Once the criteria are met, the IQ Probe establishes a call to the configured phone number (see Table 4-A) and the connection is used to carry traffic for the PVC(s) configured for DBU operation.
