Re: Connection issues - possible wiring problem

Go to solution

It looks to me as though it using one wire from each pair and the orange wire has been terminated on terminal 3 instead of terminal 2. Its an extremely simple matter to move it, you can always put it back if it doesn't work.

 

It works when connected to terminal 3 as the broadband signal will be going via a capacitor, phone wouldn't work as it would block the DC but broadband will pass through but would be improved by using correct connections.

Black is connected to 5 and orange to 3. I've ordered an IDC so i can do it properly, should arrive tomorrow. I've read online that i could determine which are the correct cables using a multimeter - can anyone advise how i could do that?

Ideally the 2 live wires should be either orange/white or black/green as they are twisted pairs, but obviously you will have to use whatever is connected at the pole end. Whatever wires have been used, they should be connected to terminals 2 & 5. First try connecting green to 2, if that doesn't work move orange to 2.

I disconnected the orange from 3 and connected the green to 2 - it has now synced at the below specs! This is after 10 mins uptime - is the FEC errors anything to worry about/can i do anything else to reduce them?

the FEC errors are inleaving doing it's job of forward error correction to help your conenction - nothing to be concerned

great thanks for your help. it does make me wonder why it was working with the ring wire connected in 3 but wouldnt with just the black in 5.

 

if it is now working does that mean that green is definitely the correct one to have in 2?
