You should check that your PHONE LINE is actually around that 186 M length.
I recollect one person posting on this site that his parents were about a similar distance from their Exchange; but their PHONE Line was about 1200 Metres long, as their PCP (green/grey Distribution Box) being about 700 M from the Exchange, so 700 M for the E(xchange) side to the PCP; plus 500 M on the D-side to come back to his parents' house.
And even the PCP to house distance in itself, can be misleading.
My PCP is literally "across the road, about 50 M away, with the Exchange cables, Fibres etc going past the corner of my house, about 5 M from the Phone entry point at my front door.
But the PHONE Line Distance from the PCP to my house is about 250 M, from the PCP the line heads a proven 125 M to the east, returning back westerly to my house by another 125 M.
Virtually all of the estate wiring is under-ground, so "not obvious".
There is a small pavement level junction box at the reversal point, which prove to be the source of problems in the early days of dial-up.
And this was a "green-field" estate, pre-wired during construction, there is no obvious reason for that routeing.
