BT Chief Executive Gavin Patterson has urged the government to recognise its efforts to improve broadband infrastructure in the UK.
The company is planning to roll out G.Fast technology and put at least to £1 billion into delivering ultrafastr broadband, provided it is given certainty from industry regulator Ofcom regarding the future of Openreach.
In its Strategic Review of Digital Communication, the watchdog stopped short of demanding that Openreach be separated from BT, although it did suggest that it be governed "at arm's length from BT, with greater independence in taking its own decisions on budget, investment and strategy".
The government this week stated that Ofcom must focus on taking whatever steps are required to resolve competition issues in the broadband market and take radical steps if necessary.
Ofcom was also urged to "confirm a clear and speedy timetable for decision-taking on the necessary changes to resolve the issues identified".
This has prompted Mr Paterson to write a letter to Culture Secretary John Whittingdale, Sky News reports.
In the letter, he pointed out that ministers have not considered BT's plans for the future, such as its efforts to upgrade its copper network with G.Fast technology and its planned investment in ultrafast broadband.
Rival providers including Sky, Vodafone and TalkTalk have been lobbying for BT and Openreach to be separated for some time, on the grounds that it would make the broadband market more competitive.
