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 Ensure that telephone lines are properly connected. Especially ensure that the telephone line connecting to the splitter is properly connected.
Step 3 Replace telephone lines and ensure that the telephone lines are not faulty.
After the HG552a1 is installed, does Internet access degrade call quality or do telephone calls lower the Internet access rate?
No. The HG552a1 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 at the same time, without degrading call quality or lowering the Internet access rate.
