摘要： Particular embodiments use aggregation logic that reduces the noise in a daisy-chained optical return signal aggregation of multiple nodes. The aggregation logic determines when an input to a transmitter/receiver is not used and disables or turns off that input. Further, in the case of daisy-chaining, a service group aggregation signal (e.g., RF signals) from the customer premise equipment (CPEs) serviced by a respective node are presented to the channel "A" port of a digital return transmitter/receiver. However, internal to the transmitter/receiver, aggregation logic auto-senses what optical return signals have already been aggregated up to that point in the daisy chain and can then intelligently place the service group aggregation signal onto one of the digital return transmitter channels. In one embodiment, if there are two return channels, A and B, whichever of these channels has seen fewer aggregations up to this point, will receive the service group aggregation signal.
