Patent ID: 7809019

Claim:
A bonding circuit for a line card, comprising: a transmit signal path for generating data fragments by fragmenting data packets; wherein the data fragments are distributed to various subscriber lines by means of a first demultiplexer and wherein the data fragments are transmitted via subscriber lines of a line bundle to a terminal connection associated with the respective line bundle; a receive signal path for generating data packets by reassembling data fragments, which are received via various subscriber lines of a line bundle from a terminal connection belonging to the respective telephone line bundle and are combined by means of a first multiplexer; said first demultiplexer comprising a first group of demultiplexer outputs which are connected via at least one data fragment buffer to a terminal connection and a second group of demultiplexer outputs being fed back via at least one data fragment buffer with adjustable delay to inputs of the first multiplexer; and a second demultiplexer connected between a transmit data packet buffer and a fragmenting circuit, said second demultiplexer comprising a first output connected to an input of the fragmenting circuit and a second output connected directly to an input of the first demultiplexer.
