Busy Hour Crosstalk Noise: What It Is and How to Avoid It

Busy hour crosstalk noise is a type of telecommunication interference that affects almost all digital subscribers and can be noticed in audio and video applications. Essentially, busy hour crosstalk noise occurs when the crosstalk between two lines performing the same function within the same digital subscriber line becomes excessive. As a result, it interrupts the data flow and causes a degrading of the quality of voice and video communications.

This type of interference is especially noticeable during peak hours, or the “busy hour” as it is often referred to. This is because when there is more traffic on the lines, the amplitude of the crosstalk is higher. This can lead to noticeable audio and video degradation. In order to understand how to avoid this interference, it is important to understand what causes it in the first place.

The main cause of busy hour crosstalk noise is the electrical connection between two digital subscriber lines. When two lines are coupled in this manner, the cables can transmit electrical signals from one to the other, which is referred to as crosstalk. As the traffic increases on each line, the crosstalk can become significant and can cause interference.

Luckily, there are a few ways to reduce or eliminate busy hour crosstalk noise. One way is to ensure that all digital subscriber lines are properly shielded and grounded. This helps to isolate the electrical signals from each other and reduces the amount of crosstalk. Another way to reduce the noise is to use good quality digital network cables and to ensure that they are not over-stretched. This can help to reduce the amount of noise.

In addition, it is also important to keep the cables clean and free of dust and debris. This helps to allow the cables to be able to properly communicate with each other and reduces the interference. Lastly, it is beneficial to reduce the number of digital subscriber lines on the same line. This is because the more lines in use, the higher the chance of interference.

By following these simple tips, it is possible to reduce or eliminate the effect of busy hour crosstalk noise. This can help to ensure a better quality of voice and video communications, and make the digital subscriber lines more efficient.
