Example: You plan to use internal extensions from 100 through 299,
and the local telephone company assigns you numbers from
617-555-4100 through 617-555-4299. If the local telephone carrier
passes you three digits, you need no translator entries in the dial plan
configuration file. If the carrier passes you four digits, you could add a
single set of translator entries to the configuration file to remove the first
digit (4) and use the remaining three digits as the internal extension.
Enabling Auto Discovery for Digital Line Cards
To enable Auto Discovery for Digital Line Cards:
1 Login to the NBX NetSet utility using the administrator login ID and
password.
1 Click System-Wide Settings > Auto Discovery.
2 Enable Auto-Discover Other Devices (including ATA, Digital Line Cards &
Analog Line Cards) check box.
3 Click .
Apply
Other check boxes might be enabled based on previous Auto Discoveries.
You do not need to clear these check boxes to install the Digital Line
Card. However, it is good practice to clear all check boxes other than the
one that you want to enable so that the Call Processor does not continue
to search for added devices.

insert the Digital Line Card.
