While the majority of the system configuration is entered during installation and should never
require changing, this page offers the system administrator the ability to change the basic
system parameters for both the wireless and Ethernet components.
Link Name: User defined identity for the unit (max 63 characters).
Link Location: Can be used as a generic scratch pad to describe the location of the
equipment.
Max Receive Modulation Mode: This is the maximum mode the unit will use as its adaptive
modulation. The modulation modes available are specified in section 21.1 ”System
Specifications”.
By default the Max Receive Modulation Mode is the highest mode available.
For minimum error rates on TDM links the user should set the maximum modulation mode to
64QAM 0.75 at both ends of the link.
Ethernet Capped Max Wireless Speed: When enabled this option will cap the wireless
speed to a mode that the connected Ethernet connection can sustain.
Maximum Transmit Power: This specifies the maximum transmit power in dBm of the
system. It is country dependent and although the user can change this in 1dB steps, it will be
limited to that country’s regulations17.
Why Reduce Transmit Power?
If the link losses are low and the link data rate and availability targets are being easily
achieved, the transmitted power level may be reduced with a consequent benefit to other
users of the band, .e.g. fixed satellite links.
17 In the UK there is a legal requirement to provide a minimum of 19dB of transmit power control
range. When the equipment is operating with a UK Licence Key, an additional facility is provided on
the configuration page that allows the transmitted power to be reduced by 19dB compared to the
maximum allowed with a simple single step control.
