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
frequency bands. Therefore, they do not interfere with each other. In this case, you
can make a telephone call and access the Internet simultaneously, without degrading
call quality or lowering the Internet access rate.
