TANDBERG 3G Gateway User Manual
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 signaling is up.
Green and Orange indicates that both layers 1 and 2 are up. Insome countries the
orange LED can blinks on a regular interval, or is turned on when there is an active call.
No LEDs light-up indicates that there is no connection or a wrong wired connection.
Note that in some countries layer 2 can be down when there is no activity (ongoing
connections). However, layer 2 should become active when a call is made or received.
Note that in case the BRI 3G Gateway is connected with less then 4 BR 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.
