Ive recently had a phone line & broadband installed using a bt connection but my isp is xln.
due to not using their router the bt engineer only left a phone line physical connection & no rj45 connection which i was expecting.
the orange/white & orange pair wires is currently used for the phone line but there are another pair of blue/white & blue wires unused.
I have my own punch tool.
question1. can anyone advise which physical interface ie rj11 which i think it should be with BT as i have an adsl cisco 837 router & i have an asa5505 rj45 connection which i would also like to use ?
