ABSTRACT:
A method and apparatus for scheduling virtual upstream channels within one physical upstream channel is disclosed. A different MAP message is received by a receiver for each virtual upstream channel from that sent downstream. Where multiple upstream receivers are used, separate MAP messages can be sent for each receiver and consequently, each virtual upstream channel. The use of multiple upstream receivers is not necessary if the upstream receiver can change the upstream channel descriptors it is using per burst.
