METHOD AND SYSTEM FOR SYNCHRONIZING SEPARATED EDGE QAM DEVICES LOCATED REMOTELY FROM A CMTS

摘要

The clocks of one or more edgeQAM (58A) devices are synchronized with a master clock (12) at the remotely located CMTS (8). A master clock signal may be transmitted via a dedicated gigabit Ether link (6). Alternatively, master clock information contained in a time synchronization message may be transmitted for use in adjusting local oscillators (68A) that drive local clocks (14) at respective edgeQAM devices (58 a...n).
