Technical foundation is the knowledge that a cable technician needs in order to work on systems from the subscriber terminals to bridging amplifiers. This knowledge includes both forward and reverse cable plant within an average neighborhood. First, a BST needs a working knowledge of Ohm s law as it applies to system powering to calculate voltage losses.
Voltage is equal to current multiplied by resistance.
They need to both be able to understand their effects on a picture, and also be able to calculate picture impairments. In addition to the above requirements, a BST must possess a basic knowledge of the decibel and its use, including the dB and its various references, with a strong emphasis on dBmV. A good service technician should be familiar with signal leakage, its rules, methods of detection, calculations and fixes. A service technician should have a strong knowledge of the rules governing these tests. We have discussed only a small part of technical foundation, but have endeavored to provide a look at what you might be expected to know, as well as to give you a place to start. SCTE now offers the training manual, Foundations for Delivering Quality Broadband Services, which may be helpful, as could the series of BST manuals.
