Hi 
Can I ask a question please

Do telephone lines go from one pole to another pole until they reach the exchange?
OR
Do telephone lines sometimes get taken from a pole - to - Underground .. at some point?
Coz!
If I use Google Street Maps to follow our telephone line...
Can follow down the street to approx 5 telephone poles - & - Then there's..
Nothing! The poles seem to stop connecting to each other

Also!
I've now realised that one half of our street ( Connected to one Pole ) follows one path to the exchange.
&
<- ->The other half of our street ( Connected to a different Pole ) follows a totally different path to the exchange.
Thanks!
Zoe
