Why is a Broadband Filter necessary?
When ADSL (Broadband) digital data is supplied on a normal PSTN telephone line then an ADSL (Broadband) Filter must be fitted between that telephone line and each item of ‘non-digital equipment because:
1 - The operation of ‘non-digital equipment may be disrupted or completely inhibited if ADSL (Broadband) digital data is allowed into it from the telephone line.
2 - The operation of the ADSL (Broadband) equipment may be disrupted or completely inhibited by the connection of unfiltered ‘non-digital equipment to the telephone line. ‘Non-digital’ equipment means anything that can be used on a normal analogue PSTN telephone line, e.g. a Phone, Fax, DualCom, Control Panel Digi-Modem.
