Synchronization in a communications system with multicarrier telephony transport

摘要

A method of staggering the arrival of frames of data at a head end in a communication system. The method includes receiving at a first service unit upstream telephony data is described. The telephony data includes a first payload message. The method includes receiving at a second service unit upstream telephony data, wherein the telephony data includes a second payload message. The method further includes formatting the first payload message at the first service unit as a first sequence of frames and formatting the second payload message at the second service unit as a second sequence of frames. In addition, the method includes transmitting the first sequence of frames on a first carrier so as to arrive at the head end at a first time and transmitting the second sequence of frames on a second carrier so as to arrive at the head end at a second time.
