Abstract

A method for transmitting digitally-encoded data is provided. The method includes receiving digitally-encoded telecommunications data (146) at a first frequency and transmitting the digitally-encoded telecommunications data (146) at a second frequency. The second frequency is greater than the first frequency. Control and timing data (150) is then transmitted after the digitally-encoded telecommunications data (146) at the second frequency. A method for transmitting digitally-encoded data is provided. The method includes receiving telecommunications data (146) at a first network interface island (11, 12, 13, 15, 17) at a first frequency. The telecommunications data (146) is then transmitted to a distributed services node (18) at a second frequency, wherein the second frequency is greater than the first frequency; transmitting second digitally-encoded data to the distributed services node with the first digitally-encoded data at the second frequency; and transmitting the first and second digitally-encoded data from the distributed services node to a second network interface island at the second frequency.
