Order of the wires A and B does not matter regarding connection of the cable mentioned
above to extension telephones.
A digital extension line can be extended to distances up to 1 km. with 0.5 mm. copper cable.
That distance can be extended even further by using thicker cables. However, it is extremely
important that there is no splice on the cable and it is supposed to be isolated from
environmental effects.
