What is a potential sign of noise or interference in downstream channels?

Intermittent operation of the service is a potential sign of noise or interference in downstream channels because it indicates that the signal being received may be inconsistent. Noise or interference can disrupt the normal flow of data, causing interruptions or fluctuations in connectivity. This can manifest as periodic drops in service, buffering during streaming, or sporadic connectivity, where the service works properly at times and fails at others. Such interruptions can stem from various external factors including electromagnetic interference, physical obstructions, or even issues within the distribution network itself. Identifying these intermittent problems can help technicians pinpoint the source of the noise or interference and take corrective action to restore stable service.
