Abstract

A system that switches between a clock signal from a first line card and a clock signal from a second line card based on information transmitted from the first line card and the second line card on timing signals is presented. Some methods include receiving a first pulse-width modulated clock signal from a first line card, the first pulse-width modulated clock signal including information regarding the status of the first line card; receiving a second pulse-width modulated clock signal from a second line card, the second pulse-width modulated clock signal including information regarding the status of the second line card; producing a clock signal from the first pulse-width modulated clock signal; and switching to producing the clock signal from the second pulse-width modulated clock signal based on the information in the first pulse-width modulated clock signal.
