Abstract |
AB |
[EN] The pushbutton telephone terminal, with automatic dialing, has a selection keyboard with integrated memory and an electronic call-number memory from which the full number is obtained by selecting a two-digit short code. The read-out number passes from the call-number memory to the keyboard memory. By depressing a given button, the contents of the keyboard memory can be read out any number of times. A further button operates a relay that takes over the function of cradle switch. The read-out number is displayed and four LEDs indicate ready-to-use, write-in, automatic dialling and repeat. |
