<p>A telecommunications system (18) capitalizes employment of a system frame number (SFN) for synchronizing plural real time clocks (206) provided at one or more nodes of the network. System frame signals (e.g., pulses) are distributed from a source (210, 310) to processors (202) having slave clocks (206S) that need to be synchronized with a master clock. A master processor (202M, 302T) sends a clock set message (500) to the processors, the clock set message including a reference master clock time (506) and a reference system frame number (504). The recipient processors which receive the clock set message resynchronize their respective slave clocks using the reference master clock time and the reference system frame number. In one mode, the clock set message directs the recipient processors to set their respective slave clocks to the reference master clock time upon the recipient processors obtaining the reference system frame number. In another mode, the clock set message advises the recipient processors of an actual master clock time at the reference system frame number, thereby enabling the recipient processor to calculate an adjusted slave clock time.</p> |
