CONFIGURING
SIGNAL STATE AND
LOOPBACK CONTROL
OPTIONS
In the Advanced dialog box, you can configure non-standard signal state and
loopback control options.
 Procedure
1 In the Gateway interface, on the sidebar, click Gateway (if not already
selected).
2 Click the applicable Port tab.
3 Click the Physical Interface button.
4 Click the Advanced button to configure non-standard signal state and
loopback control options:
 Force Signal State—Enables separate control over signals. When
you uncheck a specific signal option, signaling control is defined by
the standard logic of the Gateway. When you check a specific signal
option, you can force the signal to the on or off state. Signals can be
on all the time or off all the time.
 Enable Local Loopback—Enabled for non-KG-Device terminal
adapters only. When checked, instructs the Gateway to perform
loopback locally to the specified port without the involvement of a
remote entity. The Gateway raises an LL control signal to request
that the DCE device moves to loopback mode.
 Enable Remote Loopback—Enabled for non-KG-Device terminal
adapters only. When checked, sends a loopback command via the
specified port to an endpoint on the remote side of the serial
interface. The Gateway raises an RLB control signal to request that
the DCE device moves to loopback mode.
