3 Set the radio frequency in the
Frequency control (Local)
section:
i
In the
TX Frequency (MHz)
field, set the transmission radio frequency in
MHz.
ii In the
RX Frequency (MHz)
field, set the received radio frequency in MHz.
iii Click
Apply
. The system automatically calculates and displays the
frequency separation in the
TX to RX frequency separation (MHz)
field,
based on the configured TX and RX frequencies.
iv Optionally, select
Set also remote unit
to apply the frequency settings to
the remote unit as well as the local unit.
Notes:
If the carrier belongs to a 4x4 MIMO group, an AFR group, or an XPIC
group, you must disable the group before changing the TX or RX
frequency.
For IP-20V, a frequency scanner is available to scan the frequency
range covered by the currently configured MRMC script and
determine the current interference level for each channel. This
enables you to select the best channel in accordance with current
interference levels. See
Running the Frequency Scanner (IP-20V)
4 Set the other radio parameters in the
Configuration parameters
section:
i
In the
TX Level (dBm)
field, enter the desired TX signal level (TSL). The
range of values depends on the frequency and RFU type.
ii To mute the TX output of the radio carrier, select
Unmute
in the
TX Mute
field. To unmute the TX output of the radio carrier, select
Off
. To configure
a timed mute, select
Mute with Timer
.
If you select
Mute with Timer
, an additional field appears:
Mute timeout
(minutes)
. This field defines a timer for the mute, in minutes (1-1440).
When the timer expires, the mute automatically ends. This provides a fail-
safe mechanism for maintenance operations that eliminates the possibility
of accidently leaving the radio muted after the maintenance has been
completed. By default, the timer is 10 minutes.
Note:
In contrast to an ordinary mute, a timed mute is not persistent. This
means that if the unit is reset, the radio is not muted when the unit
comes back online, even if the timer had not expired. Also, in unit and
radio protection configurations, a timed mute is not copied to the
mate unit or radio, and no mismatch alarm is raised if a timed mute is
configured on only one radio in the protection pair.
iii In the
Link ID
field, enter a unique link identifier from 1 to 65535. The Link
ID identifies the link, in order to distinguish it from other links. If the Link
ID is not the same at both sides of the link, a Link ID Mismatch alarm is
raised. If Link ID Mismatch Security is enabled, traffic is also blocked on
the link. See
