Figure 4-13. Digital XCVR Channel Settings Window
1. Echo Canceller
It’s used to activate the echo canceller function, which is used for the transceiver when configured for
superimposed bands (transmit and receive in the same frequency band).
2. Local/Remote mode
Each time this button is pressed, it toggles between local and remote mode; for a link to be established,
one end must be configured as ‘local’ and the other end as ‘remote’.
3. Tx Pilot High and Rx pilot High
To setup a digital channel using superimposed bands it’s necessary to set the transmitted pilot and
received pilot separated at the upper and lower edges of the QAM band. These two checkboxes are
used to indicate which pilot, either the transmitted or received one, is to be located in the high edge of
the digital bandwidth.
4. F6 enable
This parameter is activated when F6 teleprotection is used. Activating this checkbox causes the dplc to
monitor when a trip is sent to squelch the QAM spectrum.
