2672 CHAPTER 175: E1 AND T1 CONFIGURATION COMMANDS

timeout time of answer signals for internal function call in a module is configured at the terminating point.

clear-backtime: Timeout time in milliseconds of R2 clear-back signal, in the range of 100 to 60,000 with a default of .10,000. After the terminating point sends a clear-back signal, it should recognize the forward signal sent back by the originating point within the timeout time.

clear-forwardtime: Timeout time in milliseconds of R2 clear-forward signal configured at the originating point, in the range of 100 to 60,000 with a default of 10,000. After the originating point sends a clear-forward signal, the terminating point should send back a corresponding line signal, clear-back or release guard for example, within the timeout time.

seizure time : Timeout time in milliseconds of R2 seizure signal configured at the originating point, in the range of 100 to 5,000 with a default of 1,000. After the originating point sends a seizure signal, the terminating point should send back a seizure acknowledgement signal within the timeout time.

re-answertime: Timeout time in milliseconds of R2 re-answer signal configured at the originating point, in the range 100 to 60,000 milliseconds with a default of 1,000. The originating point releases the line if it does not receive another answer signal from the terminating point after it recognizes the clear-back signal.

release-guardtime: Timeout time in milliseconds of R2 release guard signal configured at the originating point, in the range of 100 to 60,000 with a default of 1,000. The originating point should send a release guard signal within the timeout time after it receives a clear-back signal from the terminating point in response to a clear-forward signal.

Description Use the timer dl command to configure timeouts of R2 line signals.

Use the undo timer dl command to restore the defaults.

This command applies to R2 signaling only.

Example # Set the timeout time of R2 seizure signal to 300 milliseconds.
