Oddly it seems to provide some rather onerous and even impossible requirements on a lot of people, and even give OFCOM some powers that seem rather far reaching.
GC20.1 is not too bad as it has a caveat of "technically and economically feasible", and basically means allowing numbers in EU to be called.
GC20.2 is hard to parse, sorry. I'll update when I understand it.
GC20.3 seems to give OFCOM super powers. It allows them to require any telephone number to be blocked for fraud or misuse, but also allows any Public Electronic Communications Services to be blocked for fraud or misuse. Now, PECS covers a mess of definitions, but reading the comms act that covers quite a few things - it could, I think, cover email, for example. This means OFCOM could block email addresses or other things.
This sounds like OFCOM could block any broadband or phone line even as they can block a whole service if they like, for something as vaguely defined as "misuse". That is quite a power OFCOM have granted themselves!
GC20.4 covers international call pricing.
GC20.5 is an issue though: "The Communications Provider shall ensure that any End-User can access a hotline for missing children by using the number “116000”".
GC20.6 is a huge problem: "For the purposes of this Condition, “Communications Provider” means a person who provides an Electronic Communications Network or an Electronic Communications Service."
It is these last two that are the problem - the whole of GC20 only makes sense for public telephone service providers, but GC20.6 means it applies to anybody that provides electronic networks or services even if not to the public. It applies to all types of network and services, not just telephone.
Even the requirements for 999/112 calling only apply where someone provides telephone service that allows calls to numbers in the national dialling plan. i.e. a naked DSL does not have to do 999. An incoming calls only line with no dial tone does not have to allow 999. This seems to mean that access to 116000 is massively more important than access to 999/112 in OFCOMs eyes.
And to be honest I am not sure what the hell 116000 is meant to be for - if I had a missing child I'd call the police. Why the hell is a special number needed for this? Will there be a stolen bike helpline next? This is not even the equivalent of childline for kids to call, which might make sense as a special EU wide number. Why the hell is 116000 so special that it has to be callable even from lines and services that would not have to allow 999/112 calls?
This also means that broadband only lines are no longer valid - we have to allow 116000. It means SDSL, EFM, fibre Ethernet are not allowed as they all have to ensure access to 116000. It means BT's new single order GEA (FTTC without phone line) will not be allowed as it has to allow 116000. It means a wifi provider (even if not providing to the public) has to ensure access to 116000. Does your wifi at home (assuming you "provide" it to others in the house) ensure they can call 116000?
What the hell are OFCOM thinking this time???
