All-figure Dialling - Problems

Problems

The continued operation of the system presented a number of problems. With the growth of subscriber dialled international calls from abroad and the incompatible allocation of letters to numbers on foreign dials, there was an increase in the number of dialling errors. In London the number of three letter codes that could be used to represent exchanges had been exhausted. Significant changes were planned to the way calls in and out of the London telephone area were to be handled that required exchange codes to be grouped together into sectors and it was not possible to implement these changes without a transition to all-figure dialling. The General Post Office produced a pamphlet All-Figure Telephone Numbers in 1965 which summarised the problems.

Famous quotes containing the word problems:

    I’m no good at being noble, but it doesn’t take much to see that the problems of three little people don’t amount to a hill of beans in this crazy world. Someday you’ll understand that.
    Julius J. Epstein, U.S. screenwriter, Philip Epstein, screenwriter, Howard Koch, screenwriter, and Michael Curtiz. Rick Blaine (Humphrey Bogart)

    If family communication is good, parents can pick up the signs of stress in children and talk about it before it results in some crisis. If family communication is bad, not only will parents be insensitive to potential crises, but the poor communication will contribute to problems in the family.
    Donald C. Medeiros (20th century)

    While the onset of puberty can vary by as much as six years, every adolescent wants to be right on the 50-yard line, right in the middle of the field. One is always too tall, too short, too thin, too fat, too hairy, too clear-skinned, too early, too late. Understandably, problems of self-image are rampant.
    Joan Lipsitz (20th century)
