SETTING REAL TIME CLOCKS IN COMMUNICATIONS NETWORKS

摘要

A real time clock request in a communications network is sent from a network element to a management system via a data communications network. The time taken from the sending of the request to the receipt of the RTC is compared with a predetermined maximum and, if less than or equal to the maximum, the network element RTC is updated. If above the maximum the value is discarded and a fresh request is sent. The received acceptable RTC may be corrected by subtracting either the minimum transmission time or half the actual transmission time.
