Which of the six troubleshooting steps can likely be combined and
performed at the same time or performed out-of-sequence?
Give this one a try later!
In hardline splitters, directional couplers, power inserters, and distribution taps, the
seizure screw makes a mechanical and an electrical connection between the device
and the hardline coaxial cable connector pin.
RF distribution tap values indicated on the tap face plate by a sticker or number
stamped into the housing is the signal loss(in dB) between the downstream tap
input port and the tap (drop) ports.
Because an S-CDMA transmission has more average power than a comparable
transmission using A-TDMA, the maximum amplitude from a DOCSIS 2.0 modem
, using S-CDMA is lower than one using A-TDMA.
Although troubleshooting is a problem-solving technique that follows a
systematic process of analysis, isolation, and diagnostics, all six
troubleshooting steps can be combined or performed out of sequence.
