ADSL line interfering with chip&pin card reader
A business I'm working at has an ADSL line and chip&pin card reader for financial transactions. I have micro-filter (that came with the ADSL modem/router) between them but there is still interference, to the point where, the ADSL stops the card reader dialling out.
Can anyone suggest a better micro-filter between the units or is a completely separate analogue telephone line needed.?
Many thanks in advance

Typically you have a filter that has one port for the DSL and another for the phones which would normally include anything with a modem that dials out. They look like this.
However all the phones or devices on that line need the individual filters.

Thanks guys..
I have plugged a telephone in and there is audible interference despite using a micro-filter like the one in your photo, Dave.
When the card reader and ADSL are plugged in the ADSL works fine.. but the card reader blinks red every time a transaction is attempted. So it appears the ADSL is effecting the card reader's analogue line.
Are there different grades of micro-filter.?
ie one that is more 'industrial' in strength..?
