Method and apparatus for transforming low bandwidth telecommunications channels into a high bandwidth telecommunication channel
Low bandwidth telecommunications channels are transformed into a high bandwidth telecommunications channel by determining the relative transmission delays among a plurality of relatively low bandwidth channels which are to be combined into a relatively high bandwidth communications channel. The tran...

| description | Low bandwidth telecommunications channels are transformed into a high bandwidth telecommunications channel by determining the relative transmission delays among a plurality of relatively low bandwidth channels which are to be combined into a relatively high bandwidth communications channel. The transmission time delay across the plurality of low bandwidth channels is then equalized so that the time delay equalized low bandwidth channels combine to effectively form a single high bandwidth channel. The relative transmission time delays among the low bandwidth channels may be determined by transmitting an alignment (synchronization) signal across each of the low bandwidth channels, receiving the alignment signal from each of the low bandwidth channels, and measuring the time differences among the received alignment signals at each of the low bandwidth channels. Based on the measured time differences, time delay across the plurality of low bandwidth channels is equalized, so that the transmission time delay equalized low bandwidth channels may be combined to effectively form a single high bandwidth channel. |
