Appendix 1: Connecting the system to ISDN using NT1 network
adapters
Connecting
Connect the first ISDN cable from ISDN 1 on the codec to the S-interface on your first NT1 network adapter. Connect the
other ISDN cables to the appropriate NT1 network adapters.
Connect the U-interface of your NT1 adapter to the line provided from your network provider. TANDBERG can provide
NT-adapters.
For convenience the NT1 adapters could be placed inside the cabinet. If needed, use the shorter ISDN cable (RJ45
connectors) delivered with the NT1 between the codec and the NT1 and the longer ISDN cable between the NT1 and
the connector (RJ45) at the wall socket.
Configuring
The configuration of the codec is performed in the same manner as described in ISDN BRI Settings.
The NT1 should be powered up and you should check that the network is active. Please check your NT1 User Manual.
