Cisco TelePresence ISDN Link
Installation guide
Front panel
The LED indicators are located on the front panel of the unit.
Power
The LED lights up and remains lit when the ISDN Link is powered up.
When the ISDN Link is not configured correctly this LED will be red. This will
typically happen when you power up the unit for the first time.
The LED typically turns red when there is an error with the selected interface
(BRI/PRI/NET), or possibly other system errors that require attendance. Check
the ISDN Link status information for errors:
•
When used in automatic pairing mode the ISDN Link status information is
available from the TelePresence system’s web interface.
•
When used in manual pairing mode, see the user documentation for further
details.
BRI/PRI/NET
The BRI/PRI/NET LED indicates the activated network interface type. The LED
blinks while there is call activity on the selected interface type.
LAN
The LED flickers when there is activity on the LAN network.
Endpoint
The LED flickers when there is activity between the ISDN Link and the
endpoint (codec / video system).
