An integrated circuit device for use in a line card of a network node of a digital networking system is provided. The integrated circuit device is capable of intercepting one or more control messages from at least one CPE device. The one or more control messages correspond to at least an operational status of at least one TE device associated with the at least one CPE device. The integrated circuit device is also capable of transmitting one or more rate control messages to a network processor of the network node to adapt bandwidth utilization and provide adapted data traffic flow to at least one CPE device in relation to the operational status of the at least one TE device.
