Will Battery Contact Fault Cause Problems With Broadband?

(1/4) > >>

ktz392837:
Had a sudden big drop in fttc sync so decided to report to ISP and hope to catch them on a good day.  Probably happened in the last few days. They say they have detected a battery contact fault.  Would this have an impact on sync speeds?  Will I get speed back once fixed or could it be other things also?  Thanks

burakkucat:
An xDSL broadband circuit operates in differential mode. A battery contact fault will perturb the status quo of a broadband circuit, certainly the AC balance will be degraded and the potential for RF ingress will become significantly easier.

So "yes" is the one word answer to your first question. As for the subsidiary question, who knows? Get the main problem fixed and then review the situation.

Black Sheep:
With FTTC, a battery contact fault will only affect your circuit (as outlined above ^^), if the fault is on the D-side cable ... ie: from the Cabinet to your premises.

If the contact fault is on the E-side cable, ie: from the Exchange to the Cabinet, then this would only affect your telephony service not the broadband service.

licquorice:
Hmm, not sure about that. The battery contact will still be on the metallic path regardless of whether the fault is on the E-side or D-side.

Black Sheep:
I've not disputed the battery contact will still be on the MPF, however, it will have no effect whatsoever on a FTTC circuit if the battery contact is on the E-side cable.
