A downstream channel is considered to be valid when the InfoRanger has achieved synchronization of OAM symbol timing PHY synchronization of MPEG stream PHY e recognition of SYNC MAC messages In the event that more than one downstream signal is present in the system the InfoRanger must operate using the first valid downstream signal that it encounters when scanning If necessary the InfoRanger is instructed to change to a different downstream channel via the optional parameters file Obtain Upstream Parameters After acquiring a downstream channel the InfoRanger waits for an Upstream Channel Descriptor UCD message This type of message is transmitted periodically from the CMTS and is addressed to the MAC broadcast address There is a separate UCD transmitted for each available upstream channel The InfoRanger determines if a particular upstream channel is suitable based on parameters included in the UCD message e g modulation QPSK or 16 Once a suitable upstream channel is found the InfoRanger extracts the channel parameters from the UCD waits for the next SYNC message and extracts the upstream mini slot time stamp The InfoRanger then waits for a bandwidth allocation message for the selected upstream channel before it can proceed with the next initialization process The InfoRanger may be instructed to change to a different upstream channel via the optional parameters file The next step in InfoRanger init
