The default is 20 km.
4.9.5.3.2 Phy Parameters
The Phy menu enables viewing/updating the Bandwidth parameter:
4.9.5.3.2.1 Bandwidth
The frequency bandwidth used by the radio. A change in the Bandwidth
parameter will take effect only after resetting the AU.
The Admin Status of all Channels belonging to the same AU must be disabled to
enable a configuration change in the Bandwidth parameter.
The available options are:
1 - 1.75 MHz
2 - 3.5 MHz
3 - 5.0 MHz
4 - 7 MHz
5 - 10 MHz
The current Bandwidth values applicable for systems operating in TDD Mode are
3.5 MHz and 5 MHz. The AU will reject any selection of a Bandwidth not
supported by it.
The default is 3.5 MHz.
4.9.5.3.3 Multi Channel Parameters
Each AU can include up to 4 Channels with Channels IDs from 1 to 4,
corresponding to up to 4 ODU connectors. Each ODU connector (channel) can be
connected to an ODU. The Multi Channel menu includes the following options:

NOTE
The actual value that the system will use is a multiple of the the one-way delay for a single basic
time element: N*10 km for a bandwidth of 3.5 MHz or N*7.5 km for a bandwidth of 5 MHz, where N
is a an integer from 1 to 6. The value configured for the Maximum Cell Radius will be up-rounded to
the nearest applicable value.
The read-only Actual Maximum Cell Radius (km) parameter in the Show option is the actual value
used by the AU, that may differ from the configured value.
