+0 dBmV or greater -5 dBmV +10 dBmV +15 dBmV
21. What is the primary purpose of a power inserter?
To increase the signal strength To allow remote powering of a house amplifier when an AC outlet is not available To combine RF and DC signals To split the signal to multiple outlets
22. What should be done to a DC Wall Adapter to reset the amplifier's overload protection device?
Unplug it and wait 20 seconds Press the reset button Remove the batteries Check for a short circuit
23. When installing an eMTA phone modem, what two devices can be used?
A splitter or a house amplifier A directional coupler or a house amplifier A 2-way splitter or a directional coupler A power inserter or a house amplifier
24. What are the two main types of conductors in a coaxial cable?
Inner and outer conductor Core and shield Center and outer conductor Active and passive conductors
25. What is the purpose of a messenger wire on a coaxial cable?
To protect the cable from lightning strikes To give added strength and support to the cable and reduce sagging To provide a grounding point for the cable To transmit data signals
26. What percentage of all trouble calls and signal leakages are caused by problems between the tap and customer's equipment?
Up to 50% Up to 70% Up to 90% Up to 100%
27. According to the document, what should never be used to prepare a coaxial cable for a connector?
A cable preparation tool A razor/knife A compression tool An F-connector
