Abstract
Default software is configured at manufacture to operate in DOCSIS 1.0/1.1 mode. When communication is established between a CMTS, or other similar device, and a cable modem, or other similar device, UCDs are collected. If no UCD is collected that refers to a upstream channel associated with DOCSIS 2.0, then the device continues to register as a DOCSIS 1.0/1.1 device. If a collected UCD refers to an upstream channel having components associated with DOCSIS 2.0, then the device stores the current downstream channel frequency, overwrites the stored DOCSIS 1.1 flag with a DOCSIS 2.0 value, and shuts down. Upon restart, the stored channel frequency is tuned, the DOCSIS 2.0 mode is used, and the boot process continues in DOCSIS 2.0 mode.
