During the process of making a 2pair cable longer i think 2 wires touched and now the phone is dead (this extension only)all other phones on the system are working.I noticed 3 or 4 small glass fuses back on control panel,could one of these be blown or does anyone have any ideas?Thanks in advance for your help.

have you tried powering down for 10 minutes so and then powering up?

I don't think the fuses have anything to do with it but they are easy enough to check

since it happened while making the cord have you verified that the cord is good ?

Thanks for the quick reply,i replaced the wall outlet onto the original cable and still the same,i will try powering it down in the morning.it is 1:20am now in dublin so i have left the place till tomorrow.

Thanks again
Paul

I tried the powering down and back up but still no joy,anymore ideas would be very welcome?

you need to start at the system and verify there is nothing there could be you blew the port , hooking a phone up directly will tell that

you also could go into programing and take a look at the port

Can i find a service manual anywhere?

Hi Skip,

I tested both pairs in the outlet socket and i am getting 24 volts on both pairs,now i am confused,would this mean the port is ok?

Cheers

Paul

I don't recall the voltages , Ive never been real keen on testing that way ,true test to me is a phone comes up .

have you tried reversing polarity on the second pair?

some of the early tie /Nitusko stuff was polarity sensitive

it was already reversed when i went to it and it was working

so did you leave it reversed or put it back correctly?

I would try reversing however its wired now . It wont hurt anything
