FDX

Question 1

You can use this if there is no bi-directional DOCSIS registration test point for the legacy channels

Answer 1

Use a 2 way splitter

Question 2

This test determines if a premise can support mid-split

Answer 2

iHAT

Question 3

This predicts the echo and then excludes that predicted echo from the energy transmitted by an FDX device

Answer 3

Echo cancellation

Question 4

These pieces of equipment need to be updated to include echo cancellation

Answer 4

Amplifiers, nodes, modems

Question 5

This tests to see if a home can access all spectrums necessary for DOCSIS 4.0

Answer 5

fHAT

Question 6

This is the maximum download speed of FDX/DOCSIS 4.0 per CableLabs specifications

Answer 6

10 Gbps

Question 7

iHAT

Answer 7

in Home Assessment Test

Question 8

This component works in conjunction with the RF amplifier board to cancel echoes based on the predicted reflection

Answer 8

SOC (System on a Chip)

Question 9

FDD stands for this

Answer 9

Frequency Division Duplexing

Question 10

This is the frequency range that is utilized for FDX’s overlapping spectrum

Answer 10

108 MHz to 684 MHz

Question 11

nHAT

Answer 11

Neighborhood Home Assessment Test

Question 12

Modem transmissions that might interfere with neighbors’ signals due to high levels

Answer 12

Power bleed

Question 13

This is the maximum upload speed of DOCSIS 3.1

Answer 13

2 Gbps

Question 14

fHAT

Answer 14

FDX-Ready Home Assessment Test

Question 15

FDX uses this to provide bandwidth for additional upload speeds

Answer 15

Overlapping upstream and downstream channels

Question 16

Modems will use these when there is a catastrophic disruption of FDX upstream and downstream channels

Answer 16

DOCSIS 3.0/3.1 channels to transmit and receive signals

Question 17

This allows overlapping channels to move data upstream and downstream at the same time in the same frequency space

Answer 17

Echo cancellation

Question 18

This test identifies neighbor interference

Answer 18

nHAT
