FAQs EchoLife HG556 Home Gateway User Guide  8-6  Huawei Proprietary and Confidential      Copyright © Huawei Technologies Co., Ltd.   8.8 What can I do if Web pages often cannot be displayed during Web page browsing and can be displayed after the terminal is restarted?  Step 1 Ensure that the terminal and other devices such as telephones or fax machines are connected to the telephone line through a splitter. For details about how to install a splitter, see the related description in the manual. Step 2 Ensure that telephone lines are properly connected. If the telephone lines are improperly connected, the stability of the network connection is affected. Step 3 Check the positions of your terminal and computer. Ensure that they are far from the electric appliances such as microwave ovens, refrigerators, or cordless telephones that generate strong magnetic or electric fields. If the problem persists, contact your service provider. 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 Ensure that telephone lines are properly connected. Step 3 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 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.
