BROADBAND SNR MARGIN TWEAK Increase Broadband Speed. Signal to Noise Ratio SNR margin tweaking allows broadband users to fully take control of their ADSL or ADSL2 broadband connection to squeeze out the very highest speeds possible. With SNR margin tweaking, your downlink broadband speeds are no longer dictated by equipment shown above in the BT exchange. SNR margin adjustment could more than double your downlink connection speed on its own When combined with some of our other recommendations, such as an ADSL faceplate and a better modem router, you could get even greater broadband speed improvements. What is the target SNR margin The target Signal to Noise Ratio SNR margin is particularly important in defining your broadband download speed. It effectively defines the buffer required in signal to noise ratio to protect your broadband connection from the fluctuations that can occur over time in signal and noise levels. Poorer lines tend to require higher target SNR margins to avoid regular disconnections.

The exchange equipment attempts to set the downlink connection speed such that there is a sufficiently high SNR margin to guarantee a reliable connection without regular drops andor an unacceptable number of errors. This specific margin that the exchange tries to achieve is called the target SNR margin. The higher the target SNR margin, the lower your connection speed. As we will discuss, since a modem measures the downlink SNR and reports this measurement back to the BT exchange equipment which then sets the downlink connection speed, it is possible with some modems to adjust this measurement so that the BT exchange equipment believes that the SNR is higher than it really is so that it sets a higher connection speed than it would have done. BT can increase your downlink target SNR margin to 1. BWhen your broadband service is first switched on, the target SNR margin is set by the BT exchange equipment at 6 d. B. On a good line, BT generally considers that a 6 d. B SNR margin is appropriate to maintain a connection without a significant number of drops or errors. The corresponding target margin for Talk. Talk equipment is 9 d. B. As part of the Digital Line Management process, the exchange equipment continuously monitors your broadband connection, for example recording the number of times that it drops and the number of errors it suffers. Linksys Wag354g Firmware Download' title='Linksys Wag354g Firmware Download' />If the line experiences any issues such as bursts of errors at a particular time, the exchange equipment can increase the target SNR margin usually in steps of 3 d. B. This action aimed at stabilising the line reduces the connection speed. BTs DLM system, or BTs manual intervention, can increase the target SNR margin to a maximum value of 1. B. Many things can cause the exchange equipment to increase the target SNR margin, including not using a filtered faceplate see our ADSL faceplate page for more informationa poor or faulty modem see our broadband routermodem page for information on the best modemstemporary interference e. Christmas lights or faulty electrical equipmentregularly switching your modem on and offthunderstormsa faulty broadband microfilter, or forgetting to install a microfilter on all extension phone sockets. Once the BT exchange equipment has increased the target SNR margin, it can take days for the target SNR margin to be reduced and, in some cases, it is never reduced. In the worst case scenario, you may be saddled with very slow downlink speeds caused by an 1. B target SNR margin when your line could work perfectly with a 3 d. B or less SNR margin. We will show you how to adjust your target SNR margin to any value that you desire. Routers AL. User Name.

You will no longer be a slave to Digital Line Management in your exchange Relationship between downlink speed and target SNR margin. To demonstrate the impact of different target SNR margins on downlink connection speeds, here are some results from an ADSL connection based in rural Cambridgeshire. With the modem used the Billion 7. N, it has been possible to demonstrate how the downlink connection speed is affected by the target SNR margin. In this example, the downlink speed is only 3. SNR margin is set at 1. B, which is substantially lower than the 5. BT default target SNR margin of 6 d. B. With this particular connection, it was possible to reduce the target SNR margin to only 1 d. B, while maintaining the reliability of the connection, to achieve an amazing 6.

Please bear in mind that lowering the downlink target SNR margin can increase the number of line drops or line errors, and not all lines with be stable at 3 d. B SNR margin or lower. However, you can try to see what target SNR margin works best for your line, to get the optimum balance between reliability and connection speed. Particularly where you have made significant improvements to your line for example, by purchasing a new modem or installing a faceplate broadband filter your line may be able to tolerate substantial reductions in target SNR margin without adversely affecting reliability. How can I tweak the target SNR marginThe ability to tweak the target downlink SNR margin depends critically on the make and model of your modem. Depending on your particular model of broadband modem, there are a number of methods for tweaking the target SNR margin, which include using a modem that has an integrated target SNR margin adjustment setting such as a Billion modem router which is the easiest solutionfor Netgear DG8. XX modem owners owners, installing the custom DG Team firmware, which incorporates target SNR margin adjustment. Router. Stats softwareconnecting to the modem using telnet, and issuing the adslctl configure mod snr X or command. You can easily tweak the target SNR margin with a Billion modem router. Of all the methods, by far the easiest is to purchase a Billion modem router. These incorporate a very simple target SNR margin adjustment page and full instructions are provided on our dedicated Billion 7. DXL,Billion 8. 80. NL and Billion 7. N pages. Target SNR margin adjustment with these modems is very simple, and the modems store the SNR settings even when they have been switched off. If youre considering replacing your existing modem, Billion models are perfect for broadband users wanting to get the very highest speeds from their broadband connection and we strongly recommend them. DGTeam has develop custom firmware with SNR margin adjustment. DGTeam provides unofficial custom firmware developed for selected Netgear modems. This firmware allows the downlink target SNR margin to be adjusted which cannot be done using the standard Netgear firmware. The firmware is free of charge to download, and versions are available for the following models Netgear DG8. GTNetgear DG8. 34. PNNetgear DG8. 34. N V1. Netgear DGN2. Netgear DG8. 34G V1 V2. DG8. 34G V3. DG8. G V4. Netgear DG8. GTB Annex BNetgear DG8. PNB Annex BWe have regularly used the DGTeam firmware over a number years, and have found it very reliable and easy to use. We still, however, find that broadband connections made with our favourite Billion modems are generally more robust than with Netgear modems with or without the DGTeam firmware.
