X.25 frame retry (X25FRMRTY)
Specifies the maximum number of times a frame is sent after the response timer ends when connected to this controller. The value for this parameter depends on the quality of service provided by the network and the connection to that network; that is, the frequency of lost link protocol data units.
- *SAME
This value does not change.
- X.25 frame retry
Specify a value ranging from 0 through 21 for the number of times a frame is sent.

X.25 connection retry (X25CNNRTY)
Specifies the maximum number of times that a logical link control (LLC) protocol data unit is sent after the connect response timer expires when connecting to this controller.
- *SAME
This value does not change.
- X.25 connection retry
Specify a value ranging from 0 through 21 for the number times a frame is sent.
| Top |
X.25 response timer (X25RSPTMR)
Specifies the time period allowed to return an acknowledgement when an LLC protocol data unit is sent while connected to this controller.
- *SAME
This value does not change.
- X.25 response-timer
Specify an amount of time in tenths of a second. Valid values range from 1 through 2550 in 0.1-second intervals.
| Top |
X.25 connection timer (X25CNNTMR)
Specifies the time period allowed to return an acknowledgement when an LLC protocol data unit is sent while connecting to this controller.
- *SAME
This value does not change.
- connection-timer
Specify an amount of time in tenths of a second. Valid values range from 1 through 2550 in 0.1 second intervals.
| Top |
X.25 delayed connection timer (X25DLYTMR)
Specifies the time interval between attempts to establish a connection to the controller.
- *SAME
This value does not change.
- *CALC
Use the values specified for the X.25 connection timer (X25CNNTMR) parameter and the X.25 connection retry (X25CNNRTY) parameter to determine how often and how many times to try establishing the connection.
- X.25-delay-timer
Specify a value ranging from 1 to 32767 units. Each unit represents 0.1 second. Connection attempts are repeated indefinitely at this time interval.
| Top |
X.25 acknowledgement timer (X25ACKTMR)
Specifies the amount of time to delay sending acknowledgements for received frames.
- *SAME
This value does not change.
- X.25-acknowledgment-timer
Valid values range from 1 to 2550 in 0.1 second intervals, or 0 to indicate no delay.
| Top |
X.25 inactivity timer (X25INACTMR)
Specifies the time period used to determine an inactive condition for the controller. Valid values range from 1 to 2550 in 0.1 second intervals.
- *SAME
This value does not change.
| Top |
User facilities (USRFCL)
Specifies a string of hexadecimal characters sent to the X.25 network to request additional services. The system allows up to 218 hexadecimal characters.
- *NONE
A value is not specified for the user facilities.
- *SAME
This value does not change.

Recovery limits (CMNRCYLMT)
Specifies the number of recovery attempts made by the system before an inquiry message is sent to the system operator. Also specifies the time (in minutes) that must elapse before the system sends an inquiry message to the system operator indicating that the recovery attempt count limit is reached.
Element 1: Maximum Recovery Limit
- *SAME
This value does not change.
- *SYSVAL
- The value in the QCMNRCYLMT system value is used.
- count limit
Specify the number of second-level recovery attempts to be made. Valid values range from 0 through 99.
Element 2: Recovery Time Interval
- time-interval
Specify the time interval (in minutes) at which the specified number of second-level recoveries are attempted. Valid values range from 0 through 120. If the value specified for count-limit is not 0, the value 0 specifies infinite recovery.
More information on communication recovery is in the Communcations Management book, SC41-5406.

Text 'description' (TEXT)
Specifies the text that briefly describes the object.
- *SAME
This value does not change.
- *BLANK
No text is specified.
- character-value
Specify no more than 50 characters of text, enclosed in apostrophes.
