§ Sir L. Ropnerasked the Postmaster-General how many London telephone exchanges are on subscriber trunk dialling; how many will be using this system by the end of 1962; and when he expects all of them will be doing so.
§ Mr. Bevins42 London telephone exchanges have subscriber trunk dialling at present and I expect that 63 exchanges will have it by the end of 1962. Work is in progress at a further 79 exchanges, and on present plans it will be possible by 1966 for four-fifths of trunk calls from London to be dialled. It is expected that the whole of London will have S.T.D. by 1970.
