Claim:
1. An apparatus comprising: a processor; an attenuator; a cable modem termination system (CMTS) unit for providing access to a communication network; and a memory coupled to the processor, the memory storing a first computer-readable program code that, when executed on the processor, is configured to operate the CMTS unit to receive current transmission level of one or more cable modems, determine one or more transmit level margins of the one or more cable modems, select smallest one of the transmit level margins of the one or more cable modems and use the selected transmit level margin of the one or more cable modems to derive an attenuation value to automatically adjust the attenuator of the apparatus to attenuate a signal received by the apparatus from the one or more cable modems.
