Tsunami MP.11 5012/5054-SUI Installation and Management
Interface Parameters
75
If the Signal-to-Noise Ratio (SNR) is not sufficient, you may need to set a lower data rate or use antennas with higher
gain to increase the margin between wanted and unwanted signals. In a point-to-multipoint configuration, the BSU
should have a density setting suitable for all of its registered SUs, especially the ones with the lowest signal levels
(longest links).
Take care when configuring a remote interface; check the available signal level first, using Remote Link Test.
WARNING: When the remote interface accidentally is set at too small a value and communication is lost, it
cannot be reconfigured remotely and a local action is required to bring the communication back.
Therefore, the best place to experiment with the level is at the unit that can be managed without
going through the link; if the link is lost, the setting can be adjusted to the correct level to bring
the link back.
Make your density selection from the drop-down menu. This setting requires a reboot of the unit. Sensitivity threshold
settings related to the density settings for the 5012/5054-SUI are:
•
Registration Timeout:
This is the registration process time-out of an SU on a BSU. Default is 5 seconds.
•
Rx Activity Timeout:
This is the activity time-out of an SU on a BSU. Default is 0 seconds.
•
Network Secret:
A network secret is a secret password given to all nodes of a network. An SU can only register to a
BSU if it has the same Network Secret. The Network Secret is sent encrypted and can be used as a security option.
•
Input / Output Bandwidth Limit:
These parameters limit the data traffic received on the wireless interface and
transmitted to the wireless interface, respectively. Selections are in steps of 64 Kbps from 64 Kbps to 12 Mbps on the
5012-SUI and from 64 Kbps to 108,064 Kbps on the 5054-SUI
.
NOTE:
For the 5012-SUI, the aggregate maximum bandwidth shared between input and output is 12 Mbps. If you
attempt to set the input/output bandwidth values so that the total exceeds 12 Mbps, the management interface
will automatically adjust the values to the available aggregate bandwidth of 12 Mbps. For example, the system
default is 6 Mbps for both input and output bandwidths. If you change the input to 8 Mbps, the management
interface will automatically adjust the output to 4 Mbps, for an aggregate bandwidth of 12 Mbps. The values
will not adjust automatically if the total is less than 12 Mbps.
