What is line attenuation dB?
Line attenuation (loss) is a measure of how much the signal has degraded between the DSLAM and the modem. This is largely a function of the distance from the exchange. The lower the dB, the better for this measurement.
What is the ADSL connection?
Asymmetric Digital Subscriber Line (ADSL) is a technology that provides high transmission speeds for video and voice to homes over an ordinary copper telephone wire. It will be most cost-effective in areas with a low market penetration of cable TV.
How can I speed up my ADSL?
Speed Up Slow ADSL 2+ Internet Connection
- Hardwire yourself to your ADSL2+ modem router. Before you rush off the deep end and start blaming your ISP for having slow internet connection.
- Perform a Speed Test Using Online Speed Test Websites.
- Check Modem Connections & Phone Socket Wiring.
What is a good attenuation value for ADSL?
The higher the value of this parameter, the lower the line quality and, therefore, the lower the data transfer/receipt speed. Optimal values should be between 5 and 30 dB (excellent or good line). An attenuation value of 45 dB or higher means that the line is not suitable for ADSL.
What is the standard line attenuation spread for a given speed?
The standard signal attenuation spread for a given speed is somewhere in the region of 15-20dB for ADSL2/2+ speeds and 25-30dB for ADSL1 speeds. The following is a “guesstimate” of the line attenuation and maximum attainable speed based on distance: Less than 1km = 24Mbit.
What does an attenuation value of 45 dB or higher mean?
An attenuation value of 45 dB or higher means that the line is not suitable for ADSL. The field ‘Signal attenuation’ displays two values – the first number for the direction to the subscriber (downstream) and the second number for the direction from the subscriber (upstream).
What is line attenuation (loss)?
Line attenuation (loss) is a measure of how much the signal has degraded between the DSLAM and the modem. This is largely a function of the distance from the exchange. The lower the dB, the better for this measurement. Attenuation is logarithmic and each 3dB of attenuation halves the strength of the signal power received.
