Abstract: 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.

A CAN controller in the gateway transmits and receives a message attached with a priority level (ID) to/from an ECU through a communication line, and counts, by the consecutive block number counter, the number of transmitted messages that are consecutively blocked as a result of arbitration processing as the number of consecutive blocks and stores the number as the number of allowed blocks into an allowed block number table in the storage unit in association with a priority level attached to the message received at the communication line. Every time a message is received, the controller compares the number of consecutive blocks with the number of allowed blocks for this message, and detects abnormality if the number of consecutive blocks is larger than the number of allowed blocks.

Based on the silencing signal, user equipments (UEs) not associated with the critical communications and operating in the managed band may suspend transmissions, although they may still receive downlink (DL) data.
