Abstract
A transient pre-emptor includes a processor configured to detect transients in a communications system. After the processor detects a transient in the communications system, it causes a data communications equipment to suspend or reduce data transmission during the occurrence of a subsequent transient.
Claims22
A method for reducing transmission errors in a data communications equipment having a current transmission rate, the method comprising the steps of:
- detecting a transient;
- responsive to the detecting, collecting data describing one or more subsequent transients that occur over a first predetermined length of time;
- determining, based on the collected data, a second time for rate adjustment;
- and
- at the second time, reducing the current transmission rate from a first rate.
A computer readable medium having a program for reducing transmission errors in a data communications equipment having a current transmission rate, the program comprising logic for performing the steps of:
- detecting a transient;
- responsive to the detecting, collecting data describing one or more subsequent transients that occur over a first predetermined length of time;
- determining, based on the collected data, a second time for rate adjustment;
- and
- at the second time, reducing the transmission rate or suspending transmission.
A method for reducing transmission errors in a data communications equipment having a current transmission rate, the method comprising the steps of:
- detecting a transient;
- collecting data, responsive to the detecting, said data characterizing one or more subsequent transients that occur during a predetermined period;
- determining, based on the collected data, a rate adjustment time;
- and
- adjusting, at the rate adjustment time, the current transmission rate of the data communications equipment.
