This invention relates to a method of determining an optimum point at which to synchronize a digital subscriber line in a telecommunications network, with the aim of maximizing the resulting synchronization rate while maintaining a stable line. For many lines, the signal to noise ratio (SNR) varies over the course of a day, and recurs on a daily basis. The phenomenon is often referred to as the “diurnal effect”. The SNR history for the line is monitored, and the minimum SNR for the line is determined over a 24 hour period to take into account the diurnal effect. The current target SNR margin imposed by DLM on the line is determined, for example, by interrogating the DLM system or by noting the SNR margin on the line immediately after the most recent line synchronization. The optimum point at which a resynchronization is to be performed is calculated as point when the SNR on the line is equal to the minimum SNR plus the current target SNR margin. Synchronizing when the SNR is at this point should maximize the synchronization rate, while still maintaining a stable line.
