Symmetric Digital Subscriber Line

Symmetric digital subscriber line (SDSL) can have two meanings:

  • In the wider sense it is a collection of Internet access technologies based on DSL that offer symmetric bandwidth upstream and downstream. It is considered the opposite of asymmetric digital subscriber line (ADSL) technologies where the upstream bandwidth is lower than the downstream bandwidth.
  • In the narrow sense SDSL is a particular DSL variant that supports data only on a single line and does not support analog calls.

Famous quotes containing the word line:

    “When all this is over, you know what I’m going to do? I’m gonna get married, gonna have about six kids. I’ll line ‘em up against the wall and tell them what it was like here in Burma. If they don’t cry, I’ll beat the hell out of ‘em.”
