Configuring the traffic interfaces | 109
HSS port settings
1.
Select Link or Local or Remote > Interface > Interface Summary, then select HSS (High-speed
Synchronous Serial) interface and click Configure Interface.
'Slot' shows the slot the HSS interface card is plugged into in the terminal (A – H).
'Mode' shows the interface mode provided by the HSS interface (either DTE or DCE). If there is no
interface cable plugged into the HSS port, the ‘Mode’ will show ‘No Cable’.
'Serial Mode' shows interface type provided by the HSS interface (X.21, V.35 etc). If there is no
interface cable plugged into the HSS port, the ‘Serial Mode’ will show ‘None’.
‘Baud Rate (kbit/s)’ shows the current baud rate assigned to the port by the cross connect.
‘Loopback’ loops back the port data to the customer (default is no loopback).
‘Synchronous Clock Selection’ shows the current clocking mode assigned to the port by the cross
connect.
2.
Set the HSS RTS CTS Mode as required.
The RTS CTS mode controls the state of the outgoing interface RTS CTS control line.
When the HSS interface is DCE, the outgoing control line is CTS. When the HSS interface is
DTE, the outgoing control line is RTS.
Note: Refer to “HSS handshaking and clocking” on page 111 for additional information on setting
the recommended handshaking mode for each application.
3.
Set the HSS DSR DTR Mode as required.
The DSR DTR mode controls the state of the outgoing interface DSR DTR control line.
When the HSS interface is DCE, the outgoing control line is DSR. When the HSS interface is DTE,
the outgoing control line is DTR.
