SINGLE ENDED MEASUREMENT METHOD AND SYSTEM FOR DETERMINING SUBSCRIBER LOOP MAKE UP

摘要

A method and system for determining the make-up of a subscriber loop (220) comprising sending pulses onto a loop and acquiring data based on received echo signals. Determining (7301) from the received echoes each discontinuity on the loop and, based on each discontinuity, determining a channel transfer function (7305) for each loop section preceding the discontinuity. The transfer function is then used to synthesize an inverse filter (7309). The inverse filter and acquired data are convolved for all the loop sections preceding the discontinuity (7313). The method may be further improved by modeling real and spurious echoes and subtracting these echoes from the echo es generated in the loop.
