摘要： A method and apparatus for providing dialling intervals in dialling sequences indirectly dialled by a register in which such sequences are stored, such intervals being in accordance with the dialling intervals produced by a user during direct dialling of such sequences. Direct dialled subscriber numbers which include a dialling interval after at least one digit therein, such as for line access, are stored in a reference memory along with such interval. Upon an indirect dialling of such sequence from a redial or abbreviated dialling register, a microprocessor in the telephone set compares such sequence digit by digit with sequences stored in the reference memory, and if there is a match inserts in the dialled sequence the dialling interval in the matching stored sequence. By counting the number of such agreements for each stored sequence of dialling digits, the sequence having the lowest count value can be erased from the reference memory and replaced by a new dialed sequence having a dialling interval, thereby reducing the necessary storage capacity of the reference memory. A dialling interval in a stored sequence is altered in accordance with the interval inserted by a user each time such sequence is directly dialled, thereby adapting to the dialling behavior of the user.
摘要翻译：一种用于在由其中存储这样的序列的寄存器间接拨号的拨号序列中提供拨号间隔的方法和装置，这样的间隔是在用户直接拨号时产生的拨号间隔。包括在其中的至少一个数字（例如用于线路访问）之后的拨号间隔的直接拨号用户号码与这样的间隔一起存储在参考存储器中。在从重拨或缩位拨号寄存器间接拨打这种序列时，电话机中的微处理器将这种序列逐位地与存储在参考存储器中的序列进行比较，并且如果存在匹配，则在拨号序列中插入拨号间隔匹配存储序列。通过对每个存储的拨号数字序列的这种协议的数量进行计数，可以从参考存储器擦除具有最低计数值的序列，并由具有拨号间隔的新的拨号序列替换，从而减少参考的必要存储容量记忆。存储序列中的拨号间隔根据用户每次直接拨号时插入的时间间隔来改变，从而适应用户的拨号行为。

摘要： A subscriber telephone set which comprises a multifrequency dialing tone oscillator, a microprocessor connected thereto for controlling selection of the tones produced thereby, and an acoustic signal element for producing a ringing sound corresponding to ringing tones applied thereto. The microprocessor prevents incorrect triggering of the acoustic signal element by noise voltages on the subscriber line by verifying that the amplitude of the ringing current received on the line exceeds a predetermined level, and also that the ringing current frequency corresponds to the frequency of a resetting signal internally generated within the microprocessor. Upon such verification, the microprocessor controls the dialing tone oscillator to generate a ringing tone which is applied to the acoustic signal element to cause it to generate a ringing sound, the dialing tone oscillator thereby also serving as a ringing tone generator for activating the acoustic signal element.
