your ISP's access server, line disconnection, and line disturbance. You

can check as follows:

(3)

(4)

(5)

(6)

Make sure that the ADSL line is connected properly.

Keep MT880 away from appliances with strong electric fields

or magnetic fields, such as a microwave oven and a

refrigerator.

Make sure that no telephone or fax machine is connected

directly to the ADSL line.

Replace the old ISA network adapter with a new 10/100M PCI

network adapter and install the latest driver.

Contact your ISP for help.

3. What are the advantages of the ADSL access mode

compared with ordinary dial-up and N-ISDN modes?

zThe ADSL connection has absolute higher data rate.

zThe data and voice signals are separated in the ADSL

transmission. Therefore, the data signals do not pass through

the telephone switches. This reduces the burden on telephone

switches and you do not need to pay extra telephone fee for

accessing the Internet.

4. Will the call service and the ADSL access service influence

each other?

MT880 separates the voice and data signals by the FDM technique.

Though transmitted through the same telephone line, voice and data

traffic do not interfere with each other and the two services will not be

influenced.
