Wait 3 minutes (more on a SuperStack 3 NBX system with many devices)
for the system to discover the BRI-ST card and update the database.
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. On a SuperStack 3 NBX system with many
devices, it may take more than 3 minutes. If you attach a console cable to
the CONSOLE port on the BRI-ST card and use Hyperterminal software to
view the text output, you can see status messages. See
“Connecting a
Computer to a Serial Port”
in
Chapter 10
.
Verifying a BRI-ST
Digital Line Card
After you Auto Discover a BRI-ST Digital Line Card, you can verify that it
was properly discovered by using the NBX NetSet utility, described next,
or by viewing the card’s status lights, which is described later.

Utility
To verify that the BRI-ST card has been properly discovered:
1
In the
NBX NetSet - Main Menu
window, click
Device Configuration
.
2
Click the
Digital Line Cards
tab.
3
Examine the list of Digital Line Cards to find the BRI-ST board with the
correct MAC address. The
Type
column should contain
BRI
and the
Status
column should contain
Ready
.
4
From the
Select Device Type
pull-down list, select
ISDN BRI Channel List
.
5
Click
Apply
. The ISDN BRI Channel List appears.
6
Verify that the
Ext.
column contains an extension for each channel.
7
Verify that the
Status
column contains
Ready
for each channel.
Using Status Lights
To verify that a BRI-ST Digital Line Card has been properly discovered:
1
During the Auto Discover process each of the status lights turns amber
briefly starting with span 1 (channels D, B1, and B2) and continuing
through span 4 (channels D, B1, and B2).
2
After approximately 30 seconds, the B1 status light on all four spans
turns green for approximately one minute.
3
All lights turn off when the Auto Discover process is completed.
