Note for Diva Server 4BRI and V-4BRI:
The Diva Server 4BRI and V-4BRI adapters have four ports for connecting to four
separate ISDN BRI lines. Connect all four cables as described above. You can use
any port; typically, you must specify the port number during software configuration.
The port numbers are shown below. The diagram is oriented with the edge
connector pointing downwards.
Connecting Diva Server BRI adapters in NT mode:
The Diva Server software enables you to configure Diva Server BRI adapters as
network termination (NT). This means your adapter can serve as an NT for PBXs,
for example, when coupling PBXs with the Q-Sig protocol, and it can be used for
back-to-back operation.
When connecting the adapter to a PBX that acts as terminal equipment and
therefore requires an NT to provide a clocking signal, configure the adapter as an
NT. Wire the adapter to the PBX as shown in the diagram on page 26 by applying
the appropriate assignment at the PBX connectors. Use the required termination
resistors.
