Cabletron Systems CSX1000, CSX1200 Call Interval Parameters, Call Interval Configuration Elements

USER’S GUIDE

The average throughput is 40% for the third sample rate period. This is less than the configured utilization, so out of the last 3 samples (a sliding window is in use), 1 out of 3 samples have throughput that is greater than the configured utilization. The overload condition has still not been met. No extra calls are made.

After the fourth sample rate period (20 seconds have now passed), the first sample is dropped. The average throughput for the new sample is below the configured utilization percentage. Therefore, 1 out of 3 samples have throughput that is greater than the configured utilization. No extra calls are made.

After the fifth sample period, the second sample taken is dropped. The average throughput for the new sample taken is 60%. But because the sample dropped was a sample that was greater than the configured utilization, there still are only 1 out of 3 samples that are greater than the configured utilization.

After the sixth sample period, the third sample taken is dropped. The average throughput for the new sample is over the configured utilization. The trigger then has been met; two out of three samples have met the overload condition. An extra call will be added, and the process will be reset.

USING CFGEDIT

1.Select Call Intervals from the Call Control Options menu.

2.Enter the minimum time interval between call attempts.

CALL INTERVAL CONFIGURATION ELEMENTS

MINIMUM TIME INTERVAL

The configured call interval is the minimum time between call attempts. The system will not make a call attempt in less than the configured call attempt value. However, due to the system hardware clock resolution, the actual time interval may be greater than the configured value. The default value is 0.70 seconds. The range of the configured value is 0 to 5 seconds, in 1/100 second increments. A configured value of 0 implies that the system will make call attempts without any delay between them.

CALL INTERVAL BACKGROUND INFORMATION

This parameter allows the configuration of the minimum interval between call attempts. This interval applies to the entire system, including all lines, sites, and devices.

The Call Interval is configured in terms of hundredths of seconds. The default value is .7 seconds. The range of the configured value is 0 to 5 seconds. A configured value of 0 implies that the system will make call attempts without any delay between them.

The default value of .7 seconds is compliant with the Communications Industries Association of Japan’s(CIAJ) regulation. This regulation states that no customer premise equipment should make
