摘要：
An apparatus comprising a customer node configured to couple to an access node and to receive via a channel from the access node a time of day (TOD) value and a corresponding sample index (SNUM) value, wherein the TOD value and the SNUM value are used to estimate a second time of day (TOD′) value based on a propagation delay of the channel (L-Delay), and wherein the TOD value and the TOD′ value are used to estimate a second SNUM value (SNUM′) based on L-Delay and a plurality of parameters.
