An E&M line can be extended to distances up to 2 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.

Regarding cabling of the E&M lines, order of both signaling and voice transmission wires
matters.
Those wires are supposed to be cross connected within their own groups.
