DSL/ADSL

Line attenuation is a measure of how much the signal has degraded This is measured over the distance 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 […]

Asymmetric digital subscriber line (ADSL) is a type of digital subscriber line (DSL) technology, a data communications technology that enables faster data transmission over copper telephone lines than a conventional voiceband modem can provide. ADSL differs from the less common symmetric digital subscriber line (SDSL). Bandwidth (and bit rate) is greater toward the customer premises […]
