摘要： The problem is that a measurement of the average signal quality (average modulation error ratio), does not identify poor quality signals that may be originating from an individual cable modem. The device of the present invention displays the modulation error ratio (MER) for each packet received. Since the media access control (MAC) address is associated with a packet received from an individual cable modem, a graph displaying the MER for each packet received is also displaying the MER for signals from the individual cable modems. Thus a technician viewing the display will be able to identify whether a low MER is a result of an impairment in the network or the from an individual cable modem.
