发明名称 Telephone
摘要 In a telephone with repertory dialling and redial (which includes repeat last number), when dialling out from a PABX, one emits an access code and then the wanted number. The access code causes the sender to pause for a second dial tone before continuing to send. When dialling manually the user pauses and listens for the second dial tone, so that in the redial case no access pause code appears in the redial store. In the present system of the first digit is an access code, the digit sender checks the repertory dialler for an access pause code, and if it finds one there, it inserts such a pause in the dialled out number.
