Three Networking Modes

Your gateway can be configured to provide connectivity between your cable company and

your home LAN in any one of three Networking Modes: CM, RG, and CH. This mode setting is

under the control of your cable company, who can select the mode to match the level of home

networking support for which you have subscribed. All units ship from the factory set for the

RG mode, but a configuration file which the cable company sends the cable modem section

during its initialization can change it.
