Every month my bill from my ISP and fixed-line telephone provider, Jazztel, comes with a one-page informational/marketing flyer. This month they touted “a new service to personalize even more your ADSL.” To be precise, I actually have ITU G.992.5 or ADSL2+. For me the relevant factors are that it is web-based and free.
Not only can you modify the profile for the ADSL connection, you can also obtain statistical information about the connection. Plus you can change various characteristics of the phone line such as the restrictions on outgoing calls, call forwarding, call blocking, speed dialing, and hiding your phone number. In the “old days” you had to call up and have some of this changed or you could enter a string of key taps on the hand-set to accomplish some of these. Being able to do this from a remote location using a web page is more convenient.
Rather than bore you with all the details, you can currently pick between two ADSL profiles:
|Perfil de máxima velocidad en navegación y descargas. |
Profile for maximum speed in navigation and downloads.
|Perfil principalmente orientado a juegos online. |
Profile principally oriented for online games.
I checked my ADSL connection characteristics and this is what I found:

Calculation of Statistics
|Velocidad de bajada |
|Velocidad de subida |
|Margen de ruido |
I know all about downstream and upstream rates, I am not sure what the attenuation and noise margin values indicate. My ADSL modem provides transmission statistics as well:
|Bytes ||Packets ||Errors ||Drops ||Bytes ||Packets ||Errors ||Drops
|137,439,171 ||1,486,032 ||0 ||0 ||2,141,895,292 ||1,738,395 ||52 ||0
This looks like a low error-rate so probably the attenuation and noise margin are OK.
