Modifying IP Settings You can modify the IP settings for a Digital Line Card to meet changing
requirements.
To use the NBX NetSet utility to modify IP settings, the line card must be
on the same subnetwork as the Call Processor.
The BRI and ATC/ALC daughter cards on the 3C10164D-ST card share the
same IP address. (There are no individual IP settings for channels on the
3C10164D-ST card, as they all share the same IP address.) Therefore,
depending on the configuration, you can change the IP address either of
these methods:
■
Click PSTN Gateway Configuration > Digital Line Cards , click an
extension, and then click the IP Settings tab.
■
Click Telephone Configuration > ATA , click an extension, and then
click the IP Settings tab.
If you change the IP address for any of the daughter cards, the IP address
of the other daughter cards changes as well. You can use this method
only when the Call Processor and the 3C10164D-ST are located on the
same subnetwork.
3C10165D E1 and 3C10116D T1 Digital Line Cards do not support DHCP
lease times of less than 20 minutes.
To modify the IP settings of a Digital Line Card:
1 Click PSTN Gateway Configuration > Digital Line Cards.
2 Click the MAC address of a Digital Line Card.
3 Click the IP Settings tab.
4 To assign IP addresses, enter the first address in the First IP Address field.
The system sequentially adds the remaining addresses. 3C10165D E1,
3C10116D T1, and 3C10164D BRI Digital Line Cards need only one IP
address.
Assigning IP Addresses One at a Time
To assign IP addresses one at a time per channel on cards that support
this feature:
1 Click PSTN Gateway Configuration > Digital Line Cards.
2 Click the MAC address of a Digital Line Card.
3 Click the IP Settings tab.
