Since last week I have been unable to use my EFTPOS while my Brother AIO Colour Laser MFC-9450CDN is plugged into the phone line. I have recently had some communications items moved around the office, but have also had Tesltra here to check the phone line (which worked fine according to them!).
Here is the setup as it was yesterday:
Phone line comes into patch panel, patched to an in-line ADSL filter - ADSL side dricet to ADSL modem, "Local Phone" side split between EFTPOS terminal and Brother AIO. Every time we wanted to use the EFTPOS terminal, we needed to unplug the Brother AIO. We have also had the EFTPOS terminal replaced in the last few days as we thought it was the problem. When we unplug the Brother AIO the EFTPOS works 100% of the time.
Today, I have changed the setup to:
Phone line comes into patch panel, patched to an in-line ADSL filter - ADSL side direct to ADSL modem, "Local Phone" side direct to Brother AIO, Brother AIO "EXT" (external phone) now connected to EFTPOS terminal.
I am still waiting for an EFTPOS transfaction to come through to see if this is working, but I am not confident :(
Does anyone have any ideas on what could be wrong? I am at a loss!!
