Parte˙ breve:
Come sono i collegamenti per ogni fila?
Parte lunga
Volevo tentare di individuare i coollegamenti del mio doppino, ma non c'Š nessuna indicazione; e non voglio smontarlo, non vorrei fare danni...
Vi sono 4 fibre ottiche che arrivano e vanno senza passare (ovviamente) dal ripartitore per cui dovrebbero lsciare 4 coppie di contatti vuote in entrata e 4 coppie vuote in uscita.
Io vedo la 4 e la 8 della prima fila e la 1 e la 3 della seconda fila; Suppongo che siano i 4 doppini entranti che sono stati eliminati e sostituiti dalle 4 fibre ottiche, mentre le relative coppie in uscita
sono rimaste collegate perchŠ "non si sa mai".
Secondo il mio modo di ragionare il doppino che arriva nella posizione 1 esce dalla posizione 6: entra "sopra" ed esce "sotto".
Ma forse sbaglio.
"This is the telephone distributor of my condominium
Short part:
How are the connections for each row?
Long part
I wanted to try to identify the cooling of my pawn, but there is no indication;
And I don't want to disassemble it, I don't want to do damage ...
There are 4 optical fibers that arrive and go without passing (obviously)
from the distributor for which they should 4 couples of incoming empty contacts
and 4 empty outgoing couples.
I see the 4th and 8 of the front row and the 1 and 3 of the second row;
I suppose that they are the 4 incoming doppins that have been eliminated
and replaced by the 4 optical fibers, while the relative outgoing couples
They were connected because "you never know".
According to my way of thinking the twisted pair that arrives in position
1 comes out of position 6: it enters "above" and comes out "under".
But maybe I'm wrong.

The bottom row of terminals (sufficient for five phones), is not in usage.
Any fiber optic connections, must enter an OE conversion box of some sort.
One fiber optic connection can carry an extreme number of phone services,
and there is likely more than phone being carried. It could be that the
fiber optic carries phone/data/television. But you will not know for sure, until you find the conversion equipment cabinet. The conversion equipment cabinet would normally be locked, because valuable parts are inside.
Telephone pedestals with brown+white wires, are worth nothing, which
is why the doors are left flapping in the breeze and the punch-down
blocks have to deal with bad weather all by themselves.
