METHOD AND APPARATUS FOR MATCHING D CHANNEL DATA

摘要

PURPOSE: A D channel data matching apparatus is provided to increase transference of the D channel data by realizing a subscriber matching board between a D channel manipulating board and a network terminal. CONSTITUTION: A D channel data matching apparatus comprises a subscriber matching board(200) and a D channel manipulating board(300). The subscriber matching board(200) receives data transferred through a 2B+D channel from a network terminal(100) and divides the received data into B channel data and D channel data. After furnishing of clock and synchronous signals, the B channel data is transferred to a sub highway and a duplicated D channel data is transferred through a serial control bus. The D channel manipulating board(300) receives the B and D channel data from the subscriber matching board(200). The D channel manipulating board(300) bypasses the B channel data to an upper board and packet processes the duplicated D channel data.
