TANDBERG 3G GATEWAY
USER GUIDE
In some countries layer 2 can be down when there is no
activity (ongoing connections).
However, layer 2 should become active once a call is
made or received.
BRI hardware status indication
The screenshot shows the status page of a BRI version of the
3G Gateway. The BRI status displays the conditions of ISDN
layer 1 and 2 separately. Green indicates up and in sync. Red
indicates not in sync and indicate probably a disconnected
ISDN line.
Besides the indications on the webpage each ISDN BRI
interface located at the back-side of the 3G Gateway has a
green and orange LED. The meanings of these LEDs are:
•
Green: Layer 1 of the ISDN signalling is up.
••
Green and Orange. This indicates that both layers 1 and
2 are up. In some countries the orange LED can blink on a
regular interval, or is turned on when there is an active call.
•
No LED’s illuminate. This indicates that there is no
connection or a wrongly wired connection.
Select ISDN/BRI Status to access the ISDN/BRI Status pane.
ISDN/BRI Status (BRI Versions only)
In case the BRI 3G Gateway is connected with less than
4 BRI lines, the BRI interfaces with the highest number(s)
should be left open. For example when only 2 ISDN lines
are used they should be connected with interface 1 and 2.
