The existing Data Over Cable Service Interface Specification (DOCSIS) carriers generated by field test equipment or by the CATV subscriber modems are used to determine the amplitude response of the return band in a CATV system.

A network element of a cable television network includes at least a first and a second upstream amplifier stage, a first attenuator and a first equalizer between the first and the second amplifier stage, and a second attenuator after the second upstream amplifier stage in upstream signal path direction. A target value is determined for total attenuation of the components of the amplifier. The total attenuation is a sum of attenuations of the first attenuator, the first equalizer, and the second attenuator. The attenuation of the first equalizer is preset. The attenuation of the first attenuator is set to a maximum value such the sum of the attenuations of the first attenuator and the first equalizer is below a first threshold value. The attenuation of the second attenuator is set such that the total attenuation reaches the target value.

Disclosed is a signal conductor formed as a metal oxide varistor (MOV), the MOV having a first MOV and a second MOV separated by an insulator. In some embodiments, the disclosed signal conductor may be used in a system communicably coupled to a power transmission distribution network, the system capable of launching transverse electromagnetic waves onto a transmission line, where the electromagnetic waves propagating a data signal conveyed to the system by the MOV.

Propagating a downstream (DS) Out-of-Band (OOB) signal at a frequency receivable by a set of legacy set-top boxes (STBs) while supporting enhanced upstream peak data rates. At an input of an amplifier of a physical device, a portion of the DS-OOB signal is tapped to create a tapped DS-OOB signal, which comprises both the DS-OOB signal and all other downstream signals and channels sent from a head-end to a set of customer premises equipment (CPE) via the physical device. The tapped DS-OOB signal is introduced to a band-pass filter that passes the DS-OOB signal and attenuates all other radio frequency (RF) signals to create a filtered DS-OOB signal. The filtered DS-OOB signal is amplified and coupled to a low-pass side of a high-split diplex filter to propagate onto a transmission medium coupled to the CPE. The physical device may be a high-split RF amplifier or a high-split node.
