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.
