Abstract
A modem apparatus and method to allow a single central site modem with a low processing power DSP to handle numerous DSL lines. More particularly, the modem apparatus and method take advantage of the bursty nature of Internet data traffic to allow the low processing power DSP equipped modem to handle multiple lines simultaneously. The multiple lines can be serviced via a round robin routine or via a quality of service routine, in which the data traffic on the line is analyzed for real time activity, such analysis using UDP transport layer protocol to determine real time activity. The quality of service routine also constantly monitors the data communications lines during periods of data communication to determine if a data line should be entered into the high priority queue.
