Abstract
A system and method for detecting an error in a transmission of data through an ATM cell in a ATM switching system is disclosed. The present invention allows a system manager to easily detect errors as the errors occur in the ATM switching system.
Claims12
An ATM cell bus monitoring apparatus comprising:
- an AND Gate which receives and performs a logical AND operation on a bus slave input control signal and a bus master output control signal;
- a counter which receives and counts the logically added signal from the AND Gate for a period enabled by an input clock signal;
- a comparator which compares a count value from the counter with a prestored count value and outputs a lower of the two count values;
- and
- a pre-counter which stores the prestored count value and updates the prestored count value with the count value from the counter if said count value from the counter is lower than the prestored count value.

A method of monitoring ATM cell bus comprising:
- (a) receiving and performing a logical AND operation on a bus slave input control signal and a bus master output control signal to output a logically added signal;
- (b) counting the logically added signal for a period enabled by an input clock signal to output a first count value;
- (c) comparing the first count value a prestored count value and outputting a lower of the two count values as a second count value;
- and
- (d) updating the prestored count value with the second count value if said second count value is lower than the prestored count value.
