<p>A method includes constructing a data pattern (412) for generating a reference signal to measure a specific channel characteristic, inserting (306) the data pattern in an Internet Control Message Protocol echo request, transmitting (308) an Internet Control Message Protocol echo request from a primary station across a shared physical medium to a secondary station, receiving (310) the echo request at the secondary station, transmitting (312) an Internet Control Message Protocol echo reply in response to the echo request across the shared physical medium to the primary station, receiving (314) the echo reply at the primary station, measuring (316) a bit slicer error of the Internet Control Message Protocol echo reply, and characterizing the channel quality of the communications channel as a function of the bit slicer error. The method may be used to select (200) a channel having the best relative channel quality for routing a communications signal.</p> |
