220 CHAPTER 3: DEVICE CONFIGURATION
Modifying Audio Controls
In a normal environment, you should not need to change the Audio
Controls from their default settings. If you have an issue with sound
quality and you cannot resolve it using the volume controls on the NBX
Telephones, contact your technical support representative.
CAUTION: Do not change your Audio Controls settings unless you are
instructed to do so by a qualified support representative.
Adding or Modifying
a BRI Group
A BRI-ST Digital Line Card group is one or more BRI channels that are
assigned the same characteristics. These sections tell you how to perform
these tasks:
■ Adding a BRI Group
■ Modifying a BRI Group
■ Changing BRI Group Membership
■ Removing a BRI Group
Adding a BRI Group
You add a new group when you need to assign common characteristics
to several BRI channels.
To add a BRI Digital Line Card group:
1 On the Digital Line Cards tab, select ISDN BRI Group List from the Select
Device Type drop-down list and click Apply.
2 In the dialog box that appears, click Add. The Add Group dialog box
appears.
Modifying a BRI Group
You may want to modify a Digital Line Card group to change its name,
Auto Extension assignments, or other parameters. When you modify a
group, the changes affect all of the Digital Line Cards assigned to that
group.
CAUTION: Modifying a BRI group disconnects any active calls on any
channels that are associated with the group.
