By taking control of the expectations you have, you are
More likely to improve your motivation and be a better problem solver.
What are the six steps in the troubleshooting process?
1. Identify the problem 2. Analyze the situation 3. Isolate the elements 4. Diagnose the symptoms 5. Resolve the problem 6. Verify the solution
Which of the following is a method for controlling expectations?
Identify the source of emotional overload.
Which type of set-top box (STB) operates more like Data Over Cable Service Interface Specification (DOCSIS) cable modems with return channels
STB with DOCSIS Set-top Gateway (DSG) client software and embedded DOCSIS modems.
Receipt of STB Auth data
Set-top box (STB) diagnostic
What must a technician be aware of when analyzing a digital TV (DTV) problem
There is frequently more than one contributor to a specific DTV service problem.
The attribute of being "active" as a critical thinker means
You observe and take notes relevant to the issue.
Digital set-top boxes (STB) add forward error correction (FEC) data to the modulated channel to ensure reliable reception.
False
Why should you take the time to take notes and accurately record data at each job location?
Notes and recorded data are tools that can help you accurately remember events at a site that can help you determine a plan of action or evaluate the decisions you made.
Describe the types of questions used in the five Ws method for note taking.
Who reported the problem? What problem is being reported? When did the problem first occur? Where does the problem occur in the home? Why is the problem occurring?
All QAM channel parameters
Digital signal analyzer function of an signal level meter (SLM)
What would be a positive trait associated with being a good troubleshooter?
There are several positive traits associated with being a good troubleshooter; among them are being helpful, loyal, analytical, persistent, and confident.
What are three long-term practices that can help relieve stress?
To alleviate stress, you can exercise daily, limit your caffeine intake, or develop a support system of friends and relatives.
Because the data used for modulation error ratio (MER) and bit error ratio (BER) are added during modulation, impairments on channels having good MER and BER readings occur before modulation.
True
Which of the following digital TV (DTV) trouble calls could have been avoided with customer education about the product?
Unable to order video-on-demand (VOD) programs.
You are at a customer's home and you believe you have solved the problem. When you check to be sure the resolution did not introduce any new problems, which step are you using from the six-step troubleshooting process?
Verifying the solution.
To break the habit of a negative self-talk cycle
Tell yourself "not now" and move onto a positive thought whenever negative thoughts occur.
Which of the following best describes stereotyped thinking?
Presuming that all members of a group have certain characteristics.
What might a poor attitude, a poor self-image, or physical and mental exhaustion indicate?
A poor attitude, poor self-image, or physical and mental exhaustion can indicate stress.
It is essential to pay attention to warning signs of stress overload. Poor attitude is one of the behaviors that may indicate that you are overstressed. What are the symptoms of poor attitude behavior?
A significant change in attitude with a noticeable movement toward negative, hostile, cynical, or paranoid thoughts
What does brainstorming for creative thinking entail?
Brainstorming is the act of focusing on a problem, coming up with as many solutions as possible, and then pushing the ideas as far as possible. It is best conducted in a small group with written records of all ideas put forth.
When replacing a splitter to resolve a digital TV (DTV) service problem, what does confirming the splitter output levels before attaching the output connectors do?
Confirmation reinforces the technician's confidence that the problem will be resolved by replacing the splitter.
What kind of reasoning is described as moving from a general statement that you know to be true and applying it to a new situation?
Deductive reasoning, also known as top-down logic, can be described as applying an accepted statement (premise) to a new situation.
QAM channels amplitude should be relative to analog TV channels, which is typically 6 dB lower than the amplitude of the analog TV channels.
False
During which step of the six-step troubleshooting process for a digital TV (DTV) service problem are quadrature amplitude modulation (QAM) channel measurements typically taken?
Identifying the problem.
You are at a customer's home and you are asking the customer whether the problem is intermittent or constant. Which step are you using from the six-step troubleshooting process?
Identifying the problem.
After a digital TV (DTV) service problem has been analyzed and possible causes considered, what is accomplished by isolating the various network elements?
It narrows the scope of likely problem sources.
When troubleshooting a digital TV (DTV) authorization issue, what can be verified using the set-top box (STB) diagnostic page?
STB reception of authorization message data.
Which of the following characterizes the successful troubleshooter?
Someone with an inquisitive and relentless desire to solve and fix problems.
What kind of obstacle to clear thinking is characterized by thinking about an entire group of people based on personal beliefs about or interactions with one person?
Stereotypical thinking presumes that all members of a group have certain characteristics based on interactions with one member of that group.
What are some techniques for managing stress?
Tactics for avoiding and coping with stress overload include: focusing on restoring a positive sense of self; letting go of those things that make you feel bad or overwhelmed by writing them down; dividing tasks into small, bite-size pieces; mentally celebrating each task completion; practicing positive self-talk; noticing negative thoughts; and teaching others how to treat you. Progressive relaxation, using deep breathing and a positive attitude, are also helpful in managing stress. Visualization, meditation, taking a break, and exercising help to de-stress the mind and body and to restore emotional balance.
What does a set-top box (STB) diagnostic page of a quadrature amplitude modulation (QAM) channel showing signal-to-noise ratio (SNR) near or below 30 dB indicate?
The QAM channel quality is being compromised during capture and processing.
