Guest Posted May 24, 2005 Posted May 24, 2005 Is it an ex BT ADSL line - perhaps a filter has been left on/off at the exchange or summit???? mind you I think with cable you keep the number but get a new wire coming into your house - so It cant be that then
Chris Teague Posted May 24, 2005 Posted May 24, 2005 Don't know if it's the same on NTL Smarty, but I worked for the local Cable Co over here for a while & if the switch registered the silliest of problems, it dissed the line totally until it was put right. It even flagged up if the NTE was missing for more than a minute too. We had one system on a cable line some time ago that just kept going into line fault because of the voltage difference & no one was interested (Panel Manufactorer & Service Provider). It even saw the difference in dial tone too. In the end we turned off line fault & prog'd the panel for 24 Hr test (I'm ok) signals to the ARC.

Smart Electrics Posted May 24, 2005 Posted May 24, 2005 Yea you are right Chris. NTL switches are giant DACS
Chris Teague Posted May 25, 2005 Posted May 25, 2005 Wasn't that an expensive option on the customers behalf? Nah, they have an 0800 receiver number at our ARC. sadly, this stopped in January this year. Anyone know of any other ARC still doing 0800 / Freephone reporting No's?

Smart Electrics Posted May 25, 2005 Posted May 25, 2005 Ok if you are seeing below 5ovdc then the problem as Chris has said is the line from the switch could be faulty. I would say it is a high resistance type fault. Only way to get this looked at is to call for a field tech to investigate. With BT's network if the line is on a B2 of a DACS and the line is cut or has a fault the B2 channel will fall over as it can not see a Network Termination. It is possible that the NTL switch is similar in the way it synchronises with the network. The other thing is to loop the line and measure the Ma it should be 50ma and drop to 25ma. If it fluctuates between 50ma 10ma or lower it is obviously a line fault. The thing would be to check the alarm equipment com's. Check for earth, and loop fault using your meter. Unfortunately Cable equipment is slightly different to transmission equipment that I have worked on so what I have said is to be taken as Possible faults, service conditions.
jb-eye Posted May 25, 2005 Author Posted May 25, 2005 Thanks Guys Aritech say their kit will not work with NTL. Microtech say theirs will.! we disconected the panel and then re-connected and all test signals were working OK. We have used the Pulse option, now ill just have to suck and see. Jef Customers!
