摘要： A method for synchronizing secure clocks in a system without using any external clock, a system configured to perform the method, and a computer medium storing system code. Each secure clock is adjustable subject to a set of predetermined adjustment constraints. The intersection of the adjustment constraints of all the clocks is a limit intersection. The clocks may be synchronized to an average adjusted time of the secure clocks (if the average adjusted time is within the limit intersection) or to a substitute average adjusted time within the limit intersection if the average adjusted time is outside the limit intersection. Synchronization can occur in response to a request to adjust at least one of the clocks by a proposed clock adjustment value or to synchronize at least one of them without otherwise adjusting them.

摘要： A dual locked loop is disclosed comparing preferably a GPS signal with an E1 signal and the E1 signal with the output of the loop. The GPS signal is low pass filtered to provide a low pass filtered GPS versus E1 signal that is used as a calibration for a closed loop having a second low pass filter for filtering the comparisons of the E1 and the output signal. By appropriately selecting the filter parameters, the output stability can track the stability of the local oscillator driving the NCO for short term stability, the medium term stability of the E1 signal and the long term stability of the GPS signal.

摘要： A method, apparatus and system is described for distributing accurate time-of-day information from an existing telecommunications infrastructure without modifying the existing infrastructure. In particular, the system comprises a base station device which continually receives extremely accurate time-of-day information from, by way of example and not by limitation, a GPS (Global Positioning Satellite) system, a local atomic clock, or a wired or wireless time standard. The base station periodically places time-of-day information into standard paging packets for transmission over a standard paging network. The paging packets are sent over telephone lines to the paging terminal for transmission whenever a time slot for transmission becomes available. The base station device records the actual time of transmission of the paging packet containing the time-of-day information and prepares the next time-of-day packet by placing the exact transmission time of the previous time-of-day packet sent. In the receiver, an algorithm is used to extrapolate the current time-of-day based on the history of transmitted packets containing measured time-of-day information of past transmissions.

摘要： In a telecommunication network, a method of determining the accuracy of the real time clocks associated with each element of the network is disclosed. The method comprises sending a marker signal at a predetermined reference time along with the traffic signals to one or more elements in the network and arranging the element to record the time of the arrival of the marker signal using its clock. The recorded time is then compared with the reference time at the network management centre so as to determine the accuracy. In order to correct an inaccurate clock a message signal is sent so as to cause the clock to be adjusted by the difference between the reference and its recorded time.
