Title: Splitterless multicarrier modem
Inventor: GROSS RICHARD W
IPC: H04L27/34
Filed: 2001-12-27
Abstract: PROBLEM TO BE SOLVED: To provide a modem for use in digital subscriber line communications. SOLUTION: The modem transmits and receives data over the local subscriber loop in common with voice information over the loop, while avoiding the need for voice/data splitters. The modem responds to disruptions associated with 'disurbance events', such as on-hook to off-hook transitions and the like, by rapidly switching between pre-stored channel parameter control sets defining communications over the loop under varying conditions. In addition to changing parameter control sets responsive to a disturbance event, the modem may also change transmission power levels and other system parameters, such as frequency domain equalizer characteristics. Furthermore, provisions are made for reduced bandwidth communications under selected conditions.
