A system, method and computer program product that facilitates communication between devices that implement at least one proprietary feature in a DOCSIS-compliant broadband communication system. A logical channel is established for communication between a first device, such as a cable modem termination system (CMTS), that implements at least one proprietary feature, and other devices that also implement the at least one proprietary feature. Registration information is then received from a second device, such as a cable modem, wherein the registration information indicates that the second device also implements the at least one proprietary feature. In response to receiving the registration information, the second device is assigned to the logical channel.
