							Configuring and Managing BRI-ST Digital Line Cards241
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.
Enabling Auto Discovery for Digital Line Cards
To enable Auto Discovery for Digital Line Cards:
1Log in to the NBX NetSet utility using the administrator login ID and 
password.
2In the NBX NetSet - Main Menu window, click System Configuration.
3In the System Configuration window, click the System Settings tab.
Depending on how you access this window, the System Settings tab may 
already be selected.
4Click the Auto Discover Digital Line Cards check box.
Other check boxes may be selected based upon previous Auto 
Discoveries. You do not need to clear these check boxes to install the 
BRI-ST card.
5Click OK.
Inserting the ISDN BRI-ST Digital Line Card
You do not need to remove the power cable from the chassis before you 
insert the BRI-ST card.
To insert the BRI-ST card into the chassis:
1Write down the MAC address of the BRI-ST card.
2Select a slot for the BRI-ST card in the chassis, and use a Phillips 
screwdriver to remove the blank faceplate from the slot.
3Insert the BRI-ST card into the slot.
4Slide the BRI-ST card into the chassis until you feel it touch the 
connectors. 
						

							242CHAPTER 3: DEVICE CONFIGURATION
5To seat the BRI-ST card into the connectors, press the front of the card 
firmly.
6Tighten the left and right screws on the front of the BRI-ST card to secure 
it to the chassis.
7Wait 3 minutes.
CAUTION: When you insert the BRI-ST Digital Line Card, it begins an 
initialization sequence. Also, because you enabled the Auto Discover 
Digital Line Cards check box, the system recognizes the addition of the 
BRI-ST card and begins to update its database. Allow 3 minutes for both 
of these processes to be completed.
You are now ready to configure the ISDN BRI-ST Digital Line Card.
Configuring the ISDN
BRI-ST Digital Line
CardThese sections tell you how to use the NBX NetSet utility to set up your 
BRI-ST Digital Line Card parameters:
■Configuring for ISDN BRI Signaling
■Configuring BRI Groups
■Verifying BRI Group Membership
■Completing the BRI-ST Configuration
Before you configure the BRI-ST card, you must configure the Dial Plan as 
described in Chapter 2
.
Configuring for ISDN BRI Signaling
CAUTION: Before you begin to configure the BRI-ST card, be sure to wait 
3 minutes after you insert the BRI-ST card into the chassis.
To configure for ISDN BRI signaling:
1In the NBX NetSet - Main Menu window, click Device Configuration and 
then select the Digital Line Cards tab.
2In the T1/ISDN Board List, enter the MAC address of the BRI-ST board that 
you recorded before you inserted the board into the chassis.
3Select the BRI-ST board from the list and click Modify (Figure 81
). 
						

							Configuring and Managing BRI-ST Digital Line Cards243
Figure 81   Modify Board Dialog Box — ISDN BRI
4Scroll through the Channel List to verify that the system lists all eight 
channels. Figure 81
 shows the first few channels; the channel numbers 
appear after the MAC address, separated by a dash.
Example: In the figure, the fourth line appears as:
2...00:01:03:48:e0:4e-4...New Trunk. 
The 4 after the dash indicates channel number 4.
5To change the name of the BRI-ST board, edit the contents of the Board 
Name field to help you to identify the BRI-ST board in device lists.
6Enable the On Line check box.
7Click OK.
To connect the BRI line and activate the span:
1Plug the BRI line into the BRI interface box.
2Using a category 5 Ethernet cable, connect the BRI interface box to one 
of the four ports on the front panel of the BRI-ST board.
3The Card Type field should contain ISDN BRI. If it does not, the system has 
not properly autodiscovered the board. Restart the installation process. 
						

							244CHAPTER 3: DEVICE CONFIGURATION
To verify that the span status changes from Offline to Ready:
1On the Digital Line Cards tab, select ISDN BRI Span List from the Select 
Device Type list and then click Apply.
2Enable the On Line check box.
3Click Apply.
4Verify that the word Ready appears in the ISDN BRI Span List line item 
that corresponds to this span.
The Digital Line Cards dialog box includes buttons named Config & Status 
Report and Export Report. Both of these buttons generate configuration 
and status information for the selected Digital Line Card. Because this 
information is used for troubleshooting purposes, these buttons and the 
generated reports are described in “Digital Line Card Troubleshooting”
 in 
Chapter 10
.
Configuring BRI Groups
To configure the BRI groups:
1On the Digital Line Cards tab, from the Select Device Type list, select ISDN 
BRI Group List and then click Apply.
2From the ISDN BRI Group List, select BRI Group 1.
3Click Modify. The Modify Group dialog box appears (Figure 82
).

4Select Restricted from the Tr u n k  t o  Tr u n k pull-down list.
CAUTION: If you select Unrestricted, users can transfer incoming calls to 
outgoing trunks. 3Com does not recommend this setting because it 
enables the possibility of toll fraud.
5Click the On Line check box.
6Enter 500 in each of the four AutoExt text boxes.
7Click OK.
Verifying BRI Group Membership
To verify that all channels are in the member list:
1On the Digital Line Cards tab, from the Select Device Type list, select BRI 
Group List and then click Apply.
2Select the group you want, and click Membership (Figure 83
).
Figure 83   Manage Group Membership Dialog Box
3Scroll through the Member List to verify that all eight channels are 
present.
4To transfer a channel from the non-member list to the member list, select 
the channel and click 
						

							246CHAPTER 3: DEVICE CONFIGURATION
Completing the BRI-ST Configuration
To complete the BRI-ST installation:
1Return to the Digital Line Cards tab.
2From the Select Device Type list, select ISDN BRI Channel List.
3Click Apply.
4Wait approximately 30 seconds for the status of each channel to change 
from Ready to Idle.
If the channel status does not change to Idle, verify that you have enabled 
the On Line check box for the card, the span, and the group.
While you are waiting, click Apply to refresh the list of channels and to 
see the updated status.
BRI-ST Card Status
LightsEach of the four spans on a BRI-ST card has status lights that indicate the 
status of the span (Table 42
).
Modifying a
BRI-ST CardThese sections tell you how to modify a BRI card that is already installed in 
the system:
■Modifying a BRI Span
■Modifying Audio Controls
For the BRI-ST card, you can modify only a BRI span. You cannot modify 
the board type for a BRI-ST card.

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 GroupA 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:
1Return to the Digital Line Cards tab (Figure 113
).
2From the Select Device Type pull-down list, select ISDN BRI Group List.

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.
