ADSL, ADSL2 and ADSL2+

All National Communications products can be used on a telephone line to which ADSL/ADSL2 or ADSL2+ is also used, and the Line Sharer WILL NOT affect this service.

However, ADSL/ADSL2 and ADSL2+ can affect the performance of the following products, unless a you use a HIGH QUALITY ADSL FILTER.

  • FAXSWITCH (Fax Tone detection performance may be affected)
  • MODEM SWITCH (Modem Tone detection performance may be affected)
  • MULTIPLE MODEM SWITCH (Fax Tone detection performance may be affected)
  • Model DS1, DS2, DS3 and DS6 Door Station Line Sharers (DTMF detection performance may be affected)

To avoid these problems, it is ESSENTIAL to fit a SINGLE High Quality ADSL filter immediately ahead of the Line Sharer.

Failure to do so, or use of additional ADSL filters connected direct to your telephones, MAY cause problems in the operation of your Line Sharer.

Please Note - Most ADSL FILTERS, designed for separate connection to each telephone on your line (as usually supplied with ADSL modems) are not suitable.

High Quality ADSL FILTERS suitable for the high efficiency filtering required to detect CNG Fax Tones are available from National Communications.
