Conrad Posted August 23, 2006 Share Posted August 23, 2006 My office FAX machine has started playing up and I can't send any FAX's - I can recieve them Ok. I've spoken to the manufacturer and to cut a long story short I can't use my FAX machine on a line with an active BB connection. I can try ADSL filters (which I've done) but if that doesn't work then there's noting I can do. Thing is it used to work before so I can't understand it! I've tried the machine on a different line and it does work. Surely there's something I can do? Link to comment Share on other sites More sharing options...
penguin Posted August 23, 2006 Share Posted August 23, 2006 are you on a standard bt line? we have this issue with a lot of credit card machines and atm's.... Link to comment Share on other sites More sharing options...
Conrad Posted August 23, 2006 Author Share Posted August 23, 2006 are you on a standard bt line? we have this issue with a lot of credit card machines and atm's.... Yeah, standard line with Broadband set-up on it. We've recently moved to this address and had a new line installed. The fax machine worked fine at the old address where we had BB but I can't remember if I've sent any Faxes from our new house. We've been here about 3 months so must have sent a fax.

edd_t Posted August 23, 2006 Share Posted August 23, 2006 my sister had the same problem. we had to plug the fax into a PABX mod tap, then plug that into the ADSL filter. i have tons of PABX mod taps at work if you want to try one, PM me you address.

BT do this a lot too. DACS lines limit the data bandwidth to 28,800bps so its not an issue for faxes (last time I checked they only went up to 14400). IIRC you can't have broadband on a DACS line, though. Link to comment Share on other sites More sharing options...

Nathman Posted August 23, 2006 Share Posted August 23, 2006 Are you using a standard BT analogue line? I have got my telephone, fax machine and broadband all running through the same line with no probs at all, didn't even think that there could be an issue.

Digsy Posted August 23, 2006 Share Posted August 23, 2006 Digsy, will what Edd T has (very kindly offered) work for me? To be honest mate I havn't a clue! I'm surprised that a fax machine can tell whether its attached to a BB enabled line or not, and if you can recieve faxes OK then surely you should be able to recieve too?

jackso11 Posted August 23, 2006 Share Posted August 23, 2006 Well, I am useful after all! I worked for an ISP for a couple of years and this problem came up a lot. Its BT you need to speak to, they activate the line for fax data the same as they activate the line for an ADSL connection. Whenever I spoke to BT when activating a customers ADSL they would say there is something on the line preventing ADSL (not a phisical thing, something setup their end) which most of the time turned out to be a fax setting. To get around that the customer would have to ring BT and get the fax setting removed, then they could get ADSL working. So this says to me that you can't have ADSL and Fax settings on the same line. How you had it working at the old address I don't know. Maybe if ADSL is already set up it allows you to set up fax afterwards, but deffinatly not the other way around.

Conrad Posted August 23, 2006 Author Share Posted August 23, 2006 Cheers for the replies guys! Although I'm still non the wiser! I did call BT but kept getting some Indian call centre who apart from running a test on the line were useless. I couldn't get them to understand what the problem was.

ivan Posted August 23, 2006 Share Posted August 23, 2006 Just a quick suggestion - try putting 141 in front of the number when you're sending. That has the effect of bypassing any routing and uses BT lines instead. May not be applicable in your case, but worked here because our LCR people were using dreadful lossy compression.

Pabs Posted August 23, 2006 Share Posted August 23, 2006 Seen same issue here many times (work in IT) Most people get an additional line for the fax. Using the same line meant every time a fax was sent or received, the bb cut off Link to comment Share on other sites More sharing options...
