The OTO-ID is the number of the fibre optic socket. The fibre-optic socket is usually located in the living room - usually next to the main telephone socket. The number is printed on the socket and usually starts with B.xxx, A.xxx or rarely with O.xxx.
If a fibre optic box is already installed, we need the OTO-ID to be able to switch on our service. If no can is installed yet, this is done free of charge by a technician.
