Abstract:
A method for synchronizing a measurement in a communication system, which comprises the steps of:setting a counter to a preselected start value; while the value in the counter is not equal to a preselected final value, at a first connection point of a communication link, transmitting a first synchronization signal; at a second connection point of the communication link, receiving the first synchronization signal; at the second connection point, transmitting a second synchronization signal; at the first connection point, receiving the second synchronization signal; and incrementing the value in the counter; otherwise, transmitting a test signal at the first connection point when time equals the reception time of the last transmitted second synchronization signal at the first connection point plus a first preselected time interval; recording transmissions arriving at the second connection point beginning when time equals the reception time of the last transmitted first synchronization signal at the second connection point plus a second preselected time interval; and ceasing to record transmissions arriving at the second connection point beginning when time equals the reception time of the last transmitted first synchronization signal at the second connection point plus a third preselected time interval.
