Enabling Auto
Discover for Digital
Line Cards
Inserting the T1

into extension number 4295, and a sequence such as 4213 into 4713.
The configuration would require several translator entries to handle
subsets of the total range. A unique set of entries would handle incoming
digit sequences from 3500 through 3599, from 3600 through 3699, and
each of the other sequences in which the first two digits were unique in
the range from 37XX through 44XX.
If the DDI/DID numbers match your internal extension numbers, the
translator entries in your Dial Plan configuration file can be much simpler.
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.
To enable the Auto Discover feature for digital line cards:
1 Log in to the NBX NetSet utility using the administrator login ID and
password.
2 In the NBX NetSet - Main Menu window click System Configuration.
3 The System Configuration window appears. On the System Settings tab,
click System-wide. The System-wide Dialog Box appears.
4 Clear all check boxes associated with Auto Discover.
5 Click the Auto Discover Digital Line Cards check box to select it.
6 Click OK.
When you insert the T1 Digital Line Card into the chassis, you may leave
the system powered up. The Auto Discover process begins as soon as the
system senses the new card.

1 Find the MAC address of the T1 card on the label on the component side
of the card.
