Appendix A. Initial Settings
Specify the Desired Modulation (Data Rate)
To configure the BSU to use the modulation setting required by your application (20, 30, 40, or 60 Mbps),
from the BSU console, enter modulation <mode number>, where:
<mode number> =
0 (zero) = QAM16 (60 Mbps)
1 = QAM8 (40 Mbps)
2 = QPSK3Q (30 Mbps)
3 = QPSK1H (20 Mbps)
The BSU automatically restarts and then comes up with the new modulation setting. The Subscriber Units
adopt the new modulation setting (the new modulation setting appears in the Burst Rate field on the
Status page of the Subscriber Utility).
Note: This step is not applicable if the BSU operates at 20 Mbps only.
Specify the BSU’s Gateway Address
In general, you should specify the IP address of the router connected to the BSU as its gateway address.
If your network does not have a router installed, specify the IP address of the BSU console. To specify the
BSU’s gateway address, from the BSU console, enter gateway <gateway address> where <gateway
address> is the IP address of the router attached to the BSU or the BSU console.
Select the Routing Mode
Set the BSU to operate in IP Routing mode or Bridging mode. A BSU is set to IP Routing mode by
default. See the “routingMode” command in the Tsunami Multipoint Version 1.3 Reference Manual for
more information about these modes. After you change the routing mode, the BSU restarts and forces all
the SUs in its sector to restart. The BSU and SUs then come up with the new routing mode.
To select Bridging as the routing mode, from the BSU console, enter routingMode 1.
To select IP Routing as the routing mode, enter routingMode 0 (zero).
