Abstract
A cascaded distribution framework includes a global positioning system receiver in communication with optical line terminals. Each global positioning system receiver receives a signal from a corresponding global positioning system satellite. Each optical line terminal includes a management card for each global positioning system receiver in communication with the optical line terminal and a line card. The management card receives a global positioning system signal from a corresponding global positioning system receiver. The line card is collocated for each management card in the optical line terminal. Each line card receives a global positioning system signal from each management card in the optical line terminal, determines a signal quality score of each received signal based on a signal drift and a phase precision of the corresponding signal, and selects one of the received global positioning system signals having the highest signal quality score.
