摘要：
A pilot signal is transmitted from a transmitting device through a communication network under test to a receiving device. The pilot signal is transmitted at a known transmit time and in a voice channel. Incoming signals within the voice channel at the receiving device are monitored to detect receipt of the pilot signal. A receipt time of the pilot signal at the receiving device is identified. The one-way delay (OWD) is determined as a difference between the receipt time of the pilot signal at the receiving device and the transmit time of the pilot signal from the transmitting device.
