8.9 What can I do if noises exist during telephone calls?
Step 1
Ensure that a splitter is installed.
A splitter helps to protect the call quality of the asymmetric digital subscriber line
(ADSL) from being affected due to the interference of other type of signals.
Step 2
Step 3
Ensure that telephone lines are properly connected.
Replace telephone lines and ensure that the telephone lines are not faulty.
8.10 After a broadband terminal is installed, does
Internet access degrade call quality or do telephone
calls lower the Internet access rate?
No. The terminal uses the frequency division multiplexing (FDM) and splitter
technologies to separate voice signals from data signals. Although the two types of
signals are transmitted through one telephone line, they are carried by different
