FREE BDS Troubleshooting Systems Questions and Answers
What is the role of a Time Domain Reflectometer (TDR) in troubleshooting broadband networks?
A TDR is used to locate faults in the cable by measuring reflections along its length.
What common issue might be indicated by frequent pixelation or freezing of the video signal in a broadband network?
Frequent pixelation or freezing of the video signal can be caused by loose or damaged cables.
When experiencing a complete loss of signal in a broadband network, what is the first step in troubleshooting?
The first step in troubleshooting a complete loss of signal is to ensure that all equipment has power.
How can ingress noise in a broadband network be minimized?
Ingress noise can be minimized by ensuring that all cables and connectors are properly shielded to prevent external interference.
What does a high bit error rate (BER) typically indicate in a broadband system?
A high bit error rate usually indicates poor signal quality or interference in the system.
When troubleshooting intermittent connectivity issues, which component should be checked first?
Intermittent connectivity issues are often caused by faulty connectors or poorly terminated cable ends.
What could cause a broadband signal to weaken progressively over a distance?
Signal attenuation refers to the weakening of a signal as it travels over a distance.
Which tool is essential for detecting and locating signal leakage in a coaxial cable?
A signal meter is used to detect and locate signal leakage in coaxial cables.
If a customer reports slow internet speeds, what should be verified first?
The first step is to check the signal levels at the customer’s modem to ensure they are within acceptable ranges.
When troubleshooting a network, what is the purpose of performing a ping test?
A ping test is used to verify network connectivity between devices.
What is the effect of improper cable termination in a broadband distribution network?
Improper cable termination can cause signal reflection and loss, leading to degraded network performance.
