Note: Depending upon your product type, this dialog may vary. This help context covers all possible configuration parameters. If your dialog does not contain certain parameters, they don't apply to the product you are configuring.
-
Some of these parameters are specific to Terminal or Host operation.
-
NAU Name
-
This optional field enables you to assign a name to the port. NAU names must be unique to the unit.
-
Range: Up to eight alphanumeric characters
-
Initial State
-
This option defines the port's state at system startup. If disabled, an operator must manually enable the port.
-
Range: Disabled
-
Carrier
-
This selects the type of carrier used by the port.
-
Range: Switched (modem), or Constant
-
Clocking
-
This option determines whether the port uses internal or external clocking.
-
Range: Internal, External, X.21 Internal, or X.21 External
-
Speed
-
This value determines the speed at which the port operates. If the port is externally clocked, the speed is determined by the clocking device, providing it doesn't exceed the maximum rate.
-
Range: Dependent upon the attached devices
-
Multiple Flag Separation
-
Enable this feature if you multiple flags to separate each frame. When enabled, this feature inserts two or more flags between frames. If the port is doing several retransmission, you need to enable this feature.
-
Range: Enabled or Disabled
-
Signal Control
-
Click on this button to define the conditions which determine the port's status.
-
Pause
-
This value defines the amount of time that must elapse before a polling cycle repeats on the line.
-
Range: 0 -- 25.5 seconds (in .05 increments)
-
NRZI
-
Enable this feature if the attached devices use NRZI. If disabled NRZ is assumed.
-
Range: Enabled or Disabled
-
Ti Timer
-
This timer sets the no-response time-out for the line. After this time expires, the unit retries the transmission until the retry count expires.
-
Range: 1 -- 99 seconds
-
Slow poll Timer
-
This parameter defines the number of seconds the unit must wait between attempts to contact a PU that is off-line. This limits the wait time for off-line PUs to respond to polls.
-
Range: 1 -- 99 seconds
-
Retry Count
-
This value defines the number of times the unit attempts to complete a protocol exchange with a connected device before failing it. This prevents the unit from prematurely failing devices due to a temporary loss of response.
-
Range: 1 -- 20 times
