问题     It appears that the telephone is the principal organization element in the ordering of an information society. But whether a telephone takeover is within the realm of possibility or beyond it, today’s ordinary telephone is capable of performing electronic tricks that just a few years ago seemed possible only in the realm of science fiction.
    Your telephone already can tell you, while you are speaking to one person over the telephone, that someone else is trying to reach you. The "call waiting" service emits a soft sound which only you can hear, letting you know that someone else is trying to get through. You can hold the first call and answer the second, and if necessary, switch back and forth between the two calls.
    "Call forwarding" makes it possible for all of your incoming calls to be transferred to another number, either at a place at which you plan to be, or where someone can take messages.
    "Three-way Calling", as the name suggests, allows for a three-way conversation.
    The future opens up even more interesting prospects of new telephone services. You could arrange to have incoming calls from preselected numbers identified by different ringing patterns so that, without picking up the telephone, you could tell who was calling. Instead of repeatedly dialing someone, you could tell your telephone to keep dialing the number, when it is free, it will let you know.
    Now, all current predictions about the use of home computers for shopping, education and information gathering involve a connection with the telephone system.
