An apparatus and method for controlling home network devices is provided. The system 10 may further include a coolant system connected to the integrated motorcompressor to supply a coolant flow thereto. The replaceable acoustic liner is configured to be slideably received by the body section. A packet flow rate of each of the subflows is compared to a predefined rate limit to allow subflows of a flow to have different priorities therebetween. In response to a call arriving on an IP connection, the audible level of ring-tones that are generated by a microphone associated with a VoIP computer application is sampled, and responsive to the audible level of ring-tones being below a minimum threshold, a message is transmitting to the calling party via any available connection that the called party might be unable to hear the ring-tones. Of particular advantage is a mounting chassis that allows components a line of sight lateral to the fixture.
