As stated , if a FTTC cab is full and has waiting customers, why should existing customers hold onto their port as they swap around ISPs , benefiting from Ofcoms rules regarding competition, when the punter without access ( because the cab is full ) , is denied the benefits of competition .
This is a situation where you will always have someone disadvantaged , the ISP swapping customer complains that they lost their port when moving ISP , or the punter that cannot get onto FTTC because those already on FTTC never release their ports.
Either way , no doubt Ofcom were consulted by Openreach , which option do you expect us use , presumably the one in place is the one Ofcom selected.
As far as adding extra capacity, it’s a dead end technology, OR cannot be forced to add capacity unless they feel it’s in their commercial interests, spending potentially thousands ££’s to add capacity for potentially one extra customer when their focus is on FTTP is something OR could rightly refuse to do .
