What defines something as telecommunications?

Just curious what defines telecommunications in regards to segregation.
I've seen a definition in the TCF guilines as:
"Telecommunication is the conveyance by electromagnetic means from one device to another of any encrypted or non-
encrypted sign, signal, impulse, writing, image, sound, instruction, information, or intelligence of any nature, whether
for the information of any person using the device or not. In the context of this document, it typically implies POTS and
Data (Broadband)."
In a domestic premise it's quite simple as but in the industrial world we deal with all sorts of control and communication platforms. It's very common to have a local network switch and sheilded twisted pairs. As far as I'm aware the same rules still apply. It's just I often seen such network switches and cabling in control panels and although segregation is usually well maintained externally, it's where cables enter and inside that the minimum segregations can become hard to maintain. With more and more control moving systems moving to data based communication such as VFD etcetc
Some manufacturers and people seem to believe it's ok when the cable is designed for purpose such as properly sheilded and rated to a sufficient voltage level similar to the requirements of low and ELV but is this fair or do the telecommunications rules still prevent this? Could it be a case of if data is first then installing power cables would be non-compliant but if the power cables were first it could be ok to install such data near them as the data installation wouldn't need to comply in the same way?
