ABSTRACT:
A frequency and phase locking apparatus for a phase alignment of a plurality of temporal frames, such as synchronous optical network (SONET) frames, includes a phase locked loop 6 coupled to lock the phase of the first frame, a first frame device 8a capable of receiving the first frame and coupled to provide a synchronous frame frequency to the phase locked loop 6, subsequent frame devices 8b . . . 8n capable of receiving frames subsequent to the first frame, and a drop clock device 22 coupled to the subsequent frame devices 8b . . . 8n to set the phases of the subsequent frames in alignment with the phase of the first frame.
