HYBRID ATM ADAPTATION LAYER

摘要

IN A TELECOMMUNICATION SYSTEM THAT GENERATES MORE THAN ONE TYPE OF COMMUNICATION DATA STREAM, IN WHICH EACH DATA STREAM EXHIBITS A DISTINCTIVE DATA TRANSFER FORMAT, BANDWIDTH UTILIZATION IS IMPROVED BY FIRST REFORMATTING THE DIFFERENT DATA TRANSFER FORMATS SO THAT ALL OF THE DATA IS COMPATIBLE WITH A COMMON DATA TRANSFER PROTOCOL, FOR EXAMPLE, THE ASYNCHRONOUS TRANSFER MODE (ATM) PROTOCOL. THE COMMUNICATION DATA AND THE CORRESPONDING CONTROL DATA, REQUIRED TO MAINTAIN COMMUNICATION DATA ALIGNMENT, ARE MULTIPLEXED INTO A SINGLE DATA STREAM WHICH IS THEN TRANSMITTED OVER A COMMON TELECOMMUNICATION CHANNEL TO A RECEIVING STATION.FIGURE 21
