It shall be the duty of OFCOM, in the carrying out of their functions under sections 56 to 62—
to secure that what appears to them to be the best use is made of the numbers that are appropriate for use as telephone numbers; and
to encourage efficiency and innovation for that purpose.
It shall also be the duty of OFCOM, in carrying out those functions, to secure that there is no undue discrimination by communications providers against other communications providers in relation to the adoption of telephone numbers for purposes connected with the use by one communications provider, or his customers, of an electronic communications network or electronic communications service provided by another.
In this section "number" has the same meaning as in section 56.
