Sources of interference
Interference with Cables Try to keep cables away from power
outlets, flourescent lighting fixtures, uninterruptable power supplies, and
other sources of strong electromagnetic interference. Coiling up cables can also
cause interference.
Bouncing CPE If the CPE is bouncing, take note of where it is
located. If it's near any electric devices that may draw more current during
certain times of the day, this could cause a "bounce". Examples of such devices
include microwave ovens, floor heaters, and electric fans.
Additionally, noise induced 'radio' reception, an analog condition, may be present. When you move an AC extension cord, does the amount of noise received by a DSL system increase or decrease? If so, that extension cord may be a tuned part of the noise transmission system. This induced radio reception is similar to the reception of a distant radio station which changes during the course of the day.
