Re: Broadband Goes Off When Phone Rings

Check for faulty/missing ADSL filter(s). The function of the ADSL filter is to separate the broadband digital signal from the telephone baseband analogue signal. A missing or faulty filter will cause interaction between the two services leading to a noisy analogue signal and an unreliable broadband signal that drops out every time a phone rings or a receiver lifted. EVERY analogue device plugged into a standard telephone socket (fax, telephone, alarm systems etc), MUST have a filter fitted unless the master socket is of a type with a built in filter.


Your HH then plugs into the ADSL output of one of the filters.


Filters do go faulty.
