Default Re: "New exchange" from Norwegian STK (=STC)

Relays with 'L' in the designation are generally Line relays which operate when a line goes Off Hook. Does this tie up with the extension line numbering?

With no sign of any strowger or crossbar mechanism, if this unit is automatic, it must use some kind of relay matrix switching
