About this level

Practical summary

Class 6110 sits in the PSIC 2019 hierarchy under J Information and Communication > 61 Telecommunications > 611 Wired telecommunications activities. This class usually fans out into more specific subclasses such as Wired (landline) Services, Wired Internet Access Service Activities (e.g. Dsl, Leased Line, Dial-up), and Telegraph, Facsimile/telefax, and Telex Services. It is the level people use when they already know the activity family but still need the exact five-digit match.

Administrative context

Where this code is used

This class is used when a business can already narrow the activity family and only needs to compare the final subclasses such as Wired (landline) Services, Wired Internet Access Service Activities (e.g. Dsl, Leased Line, Dial-up), and Telegraph, Facsimile/telefax, and Telex Services. It is the level most often checked before a five-digit decision is finalized.

Selection note

How to choose it

Use this class to choose between its final subclasses such as Wired (landline) Services, Wired Internet Access Service Activities (e.g. Dsl, Leased Line, Dial-up), and Telegraph, Facsimile/telefax, and Telex Services. If two options look close, compare the exact activity, the outputs and the way the business actually earns revenue.
