Briefly define the three most common types of digital subscriber line (DSL): asymmetric, symmetric, and VDSL
What will be an ideal response?
Asymmetric: Popular for residential use, data and telephone share the same line, unequal speed of upstream and downstream bandwidth, limit of 18,000 feet from modem to DSL access multiplexer (DSLAM).
Symmetric: Voice and data cannot share the same line, equal upstream and downstream bandwidth, limit of 12,000 feet from modem to DSLAM.
Very High Bit-Rate DSL (VDSL):Much higher data capacity (12 Mbps upstream and 52 Mbps downstream), 4000-foot limit between modem and DSLAM.
