Why does the ADSL CPE fall off line so often? There are many factors concerned, such as telephone or fax machine is connected directly to the ADSL subscriber line without splitter, faults in your ISP access server or ADSL CPE (Compatibility or quality problem), ETHERNET card (Low processing speed, invalid driver), line disconnection, line disturbance, etc. You are suggested to check the following items in your applicable range. (1) Ensure no telephone or fax machine is connected directly to the ADSL subscriber line without splitter. (2) Ensure the ADSL connector is valid. (3) Keep the device away from heat source, power line or highly powered electronic equipment. (4) Telephone Line NOT have any Noise 2. How to connect multiple telephones? 28
In case you need to connect telephone more than one set. You must install Micro Filter for every branch of Telephone. Micro filter is available at True Shops. Figure 1-20 Multiple Telephones connection 3. What are the advantages compared with ordinary dial-up equipment? z High data rate. z Through Voice and data traffic are carried through a single line, the circuit switch does not process data traffic. That is, you don’t need to pay extra telephone fee for accessing the Internet. 4. Is there any possibility of losing voice quality by using ADSL CEP or threatening data rate by calling simultaneously? FDM technology is used here to separate the voice and data traffic, which are 29
totally independent to each other with standard frequency design. Even you make phone call while accessing the Internet, it will not cause the losing of voice quality or data rate. 5. Why can not I access the Internet? (1) Ensure that you have entered the correct username and password. (2) If you still cannot access the Internet, check whether the Proxy server on your IE is correctly configured. The Proxy server must be disabled. (3) Try different Websites, in case some Website fails. Try to Power Off and Power On D-Link DSL-2750E then access Internet again. 6. I cannot get online for I changed the parameters of the D-Link DSL-2750E, What can I do? Try to restore the default factory setting of the D-Link DSL-2750E as follows. (1) Find the Reset button on the bottom of the D-Link DSL-2750E. Use a needle-like object to click and hold the Reset button 10 second, and then release it. (2) Default Configure and entered the correct username and password again 30
