METHOD AND SYSTEM FOR VOICE TRAFFIC CONCENTRATION IN AN ATM/DSL HEAD-END NETWORK

摘要

An asynchronous transfer mode (ATM) digital subscriber line (DSL) head-end network (1) is disclosed which includes a network control system (11), which manages call traffic through the head-end network (1) by assigning traffic to voice channels based on available time slots from a telephone company (42). A plurality of customer premise equipment (CPE) units provide customer line terminations with telephone service. The CPE units (2) are coupled to a multiplexer (9). The network control system has an assignment mechanism, which concentrates telecommunications traffic between the multiplexer and an asynchronous transfer mode (ATM) switch (10) on the channels to compensate for a number of customer line terminations exceeding a number of voice channels on links to the telephone company (42).
