2. Select the QV24S port to configure, and click Edit.
'Slot' shows the slot the QV24S interface card is plugged into in the terminal.
'Port' shows the interface port number (1-4).
A Baud Rate of ‘OVRSAMP’ indicates that the QV24S has been configured for synchronous over
sampling mode in the Cross Connections application.
3. The CTS Source defines the mode in which the CTS signal responds to the remote DTE. Two options
are available:
CTS Source
Function
Local RTS
The local CTS signal follows the local RTS.
The status of the link does not impact on the CTS signal.
On Permanent
The local CTS is in a permanent ON (+ve) state.
This does not go to OFF if the link fails.
Note that the CTS behaviour is not impacted by the operation of the card loopbacks.
4. The Sample Data On defines the received clock edge on which the received data is clocked into the
port. Two options are available:
Sample Data On
Function
Falling Clock Edge
The falling edge of the XTXC is used to clock data into the
port.
Rising Clock Edge
The rising edge of the XTXC is used to clock data into the
port.
5. ‘Loopback’ loops back the port data to the customer (default is no loopback).
6. Click Apply to apply changes or Reset to restore the previous configuration.
