Configuring the traffic interfaces | 110
4. Set the HSS DCD Mode as required.
The DCD mode controls the state of the outgoing interface DCD control line.
This setting is only relevant if the HSS interface is DCE.
5. Set the HSS interface Clock Source.
The interface clock source allows the HSS card to provide the master clocking for the terminal.
This setting is compulsory in certain clocking modes.
One interface port in each terminal can be set to 'primary' and one interface port to 'secondary' (an
error message will appear if you try to set another port to either primary or secondary).
A port currently set to primary must be set to 'None' and applied before it can be reset to
secondary.
Note: The terminal clock source is selected in Local or Remote > Terminal > Clocking
6. Enable or disable the HSS XTxC control, as required.
Depending on the clocking mode (see “
HSS handshaking and clocking” on page 111) selected,
altering this setting will allow the terminal clock to be substituted for the external XTxC signal.
7. Click Apply to apply changes or Reset to restore the previous configuration.
