ABSTRACT:
A system facilitates initialization of devices in a cable modem network. The system may provide downstream channels for transmitting data to the devices and upstream channels for receiving data from the devices. At least one of the upstream channels may be dedicated to providing initialization opportunities. This dedicated upstream channel(s) includes less than all of the upstream channels. The system may transmit upstream channel identifiers on the downstream channels, where each of the upstream channel identifiers identifies one of the upstream channels. The system receives initialization data on the dedicated upstream channel(s).
