Abstract
The clocks of one or more edgeQAM devices are synchronized with a master clock at the remotely located CMTS. A master clock signal may be transmitted via a dedicated gigabit Ethernet link. Alternatively, master clock information contained in a time synchronization message may be transmitted for use in adjusting local oscillators that drive local clocks at respective edgeQAM devices.
