2-8 MDS Intrepid-HC HP Installation and Operation
Or click the up/down arrows in the TX Channel field to select the channel (the frequency will be updated
accordingly).
For the Frequency Control area, note the following:
Only one standard is generally shown, predetermined by the ODU parameters. When the standard is unknown,
the TX Channel field will be disabled.
TX Channel selection is possible only when a predefined standard file was installed. In some cases, you may
be able to select more than one standard.
The Rx Frequency field is read-only for systems other than 6, 7, 8, 10, and 11 GHz.
The arrow on the right side in the Frequency Control area is green when communication exists between the
local and remote units. If there is no communication between the units, the arrow is red.
4. Select the XPIC Enabled option if you want to activate the XPIC mechanism.
With The transceiver operating in co-channel dual polarization (CCDP) mode, using the cross polarization
interference canceller (XPIC) algorithm, two STM-1 signals can be transmitted over a single 28 MHz channel,
using vertical and horizontal polarization. This enables double capacity in the same spectrum bandwidth.
Note: Setting XPIC for the right drawer will effect the left drawer as well, and vice versa.
5. Select Local Only if you want to frequency changes to affect only the local unit. Select Local + Remote if you
want frequency changes to affect the remote unit as well.
Note: If there is a communication failure between the local and remote units, the Local + Remote option will be
disabled.
6. In the Transmitter Configuration area, select TX Mute to block transmission to the remote unit. By default,
this option is not selected.
Select ATPC to activate the Automatic Transmit Power Control feature.
For Set TX Level, enter or select the designated signal level. Possible range is -10 to max power level. By
default, the transmit signal level is set to the maximum power level.
The Monitored TX Level field (read-only) displays the system's transmitted power level.
7. In the Receiver Configuration area, the Set Reference Rx Level field should be set to the Rx level to which
the actual level will be compared. This field is active only if ATPC is enabled.
Receiver Mode is the Rx path, which can be set to Main, Diversity, or Combined. This field appears only if
IFC (IF Combiner) is supported.
RSL Connector Source can be Diversity or Main. This field appears only if XPIC is not supported and IFC is
supported.
The Monitored Rx Level (Main) field is read-only and displays the received power level.
Monitored Rx Level (Diversity) is a read-only field that displays the received power level of the Diversity
channel.
