This line has jumpers in place


[link to this post]
 
I notice the BT Wholesale DSL checker www.dslchecker.bt.com has started declaring "This line has jumpers in place.". Does anyone know what this means and why it's important?

Might this be of some help?
LIJs

Left in Jumper(s). A process in which a Public Switched Telephone Network (PSTN) line pair is only switched off in software, and remembered, so that software can switch on again when required. The jumper wire pair at the Main Distribution Frame (MDF) is left in place, instead of having to be removed.
A bit more poking around shows this is related to LLU provision.

Of the phone numbers I have checked, those on a non-BT telephone service have left in jumpers and those on BT have not.

Is it possible that the jumpers previously connected ADSL service and were left in place when the line was moved to FTTC?

In reply to a post by caffn8me:

Yes. That's exactly what it means, left in jumpers in the cabinet from when the line had previously been FTTC.

If someone orders ADSL these will need removing by an engineer before the service will work. I'm not sure why the public need to know this though.

My BT line has this as well. Very curious as to what it means, and what (if any) affect it has on the line.

Sorry to disappoint! My line gives: This line has jumpers in place.

My line has only ever been BT ... I have had the number for 35 years and always with BT and never migrated to anyone else.
