Figure 4-5. Dedicated PVC Management Application

Minimum Configuration Requirements

The configuration requirements for dedicated PVC management are identical to those listed for shared PVC management. See the previous section, Shared PVC Management on page 4-7, for more information.

DIAL BACKUP APPLICATION

The TSU IQ+ dial backup (DBU) option cards provide single or multiple site backup, depending on the DBU card option selected. The TSU IQ+ can be configured to originate a call based on physical layer conditions (i.e., port failures) and/or PVC outages. Once the criteria are met, the TSU IQ+ establishes a call to the configured phone number (see Table 4-1 on page 4-13) and the connection is used to carry traffic for the PVC(s) configured for DBU operation.

In the case of PVC outages (not physical layer port failure), the TSU IQ+'s two-port design allows the TSU IQ+ receiving the call to continue to use the T1 frame relay circuit for PVCs that are not affected by the outage. This is done (without the attached DTE device's intervention) by modifying the status of PVCs that are in DBU state to active when the PVC status is given to the DTE.
