Abstract
A Cable Modem Termination System (CMTS) comprising a receiver configured to receive a plurality of upstream transmission request messages from a plurality of coaxial units via an electro-optical network, wherein the upstream transmission request messages each request permission to transmit a specified amount of data, a processor coupled to the receiver and configured to allocate Orthogonal Frequency-Division Multiplexing (OFDM) minislots to each coaxial unit based on the amount of data requested in the associated upstream transmission request message, and a transmitter coupled to the processor and configured to transmit at least one Uplink Allocation Map (UL-MAP) message to indicate minislot allocations to the coaxial units.
