The operation of S11 is executed, and then the operation of step S12 is executed.

  Then, while executing the holding / updating operation of the transmission phone book data D in the parent device T (step S13), the transmission phone book data D is simultaneously transferred to the child device K3 and the child device K2 by the broadcast transmission ( Step S40).

  Here, as the processing of step S40, as in the operation of step S30 shown in FIG. 5, for example, transmission of an amount that fits in the information amount of, for example, one packet in the digital communication system that the telephone system according to the third embodiment complies with, for example. The phone book data D (one phone book record or a plurality of phone book records) is transmitted at a time and received at the slave units K3 and K2 at the same time (steps S15 and S18). Further, in this case, similarly to the transmission process from the parent device T according to the first embodiment to each of the child devices K3 and K2 (see steps S14 and S17 in FIG. 4), the information amount is equal to or less than the information amount for the one packet. After the transmission phone book data D corresponding to one phone book record R is simultaneously transmitted from the parent device T to each of the slave devices K3 and K2, the transmission phone book data D corresponding to the next phone book record R is sent to the parent device. The transmission process may be executed by repeating the transmission from T to each of the slave units K3 and K2 by the number of telephone book records R that need to be transmitted. The transmission telephone directory data D corresponding to the telephone directory record R having an information amount equal to or smaller than the information amount for the packet may be simultaneously transmitted from the parent device T to each of the child devices K3 and K2.

  After the operation of step S40, the operations of steps S16, S19, S20, S31, S23, S25, and S26 shown in FIG. 5 are sequentially executed, and the telephone book data DT according to the third embodiment is shared. Complete.

  As described above, according to the operation of the telephone system according to the third embodiment, the transmission phonebook data D is transmitted collectively from the slave unit K1 to each of the slave units K3 and K2, so Compared to the case where the book data is sequentially transmitted to each of the slave units, the transmission telephone book data D can be distributed to the necessary slave units in a short time and efficiently.

  Therefore, it is possible to improve the convenience as the telephone system S by shortening the time that must be occupied for operations other than a call with the original external telephone line X as much as possible.

  Further, since the transmission telephone directory data D is simultaneously transmitted to each of the slave units K3 and K2 by broadcast transmission from the master unit T, the initial reception operation (step S1 in FIG. 5) is performed in the master unit T and each of the slave units K2 and K3. , S5 and S9) can be avoided, and the transmission telephone directory data D can be distributed to each of the slave units K3 and K2 in a very short time.

  Further, the transmission phone book data D is composed of a phone book record R and data length information H, and only the recording area corresponding to the amount of information indicated by the data length information H is secured in each of the slave units K3 and K2. Since the transmission telephone book data D is recorded, the amount of information of the transmission telephone book data D itself can be made variable, and the transmission telephone book data D can be stored without using a useless recording area in each of the slave units K3 and K2. Since it can be recorded and used for processing, even when transmitting telephone book data D having a large amount of information is transmitted from the slave unit K1 to each of the slave units K3 and K2, the transmission can be efficiently performed in a short time. It can be performed.

  Furthermore, when a plurality of phone book records R are included as the transmitted phone book data D, only one recording area corresponding to the amount of information indicated by the received data length information H is stored in each of the slave units K3 and K2. Since the transmission telephone directory data D is recorded for each case, the telephone directory records R for a plurality of cases can be distributed at a time.

  Further, since the transmission source of the transmission telephone book data D is the slave unit K1, and the master unit T has a function of relaying the transmission telephone book data D transmitted from the slave unit K1, the direct external telephone line X Even if the updated phone book data DT possessed by the handset K1 that does not have a function of connecting to the mobile phone K1, the corresponding send phone book data D is efficiently transmitted to the other handset K3 and K2 in a short time. be able to.

(IV) variation Next, a description will be given of a modified embodiment according to the present application.

  In each of the above-described embodiments, the present application is applied to the case where the phone book data DT is shared by the parent device T and the child devices K1 to K3. In the case where the setting of the function is shared, the present application can also be applied to the case where information for sharing is transferred between the telephones constituting the telephone system.

  More specifically, for example, setting of the ring volume of the parent device T and each of the child devices K1 to K3 constituting the telephone system S according to the first embodiment (more specifically, for example, the parent device T and each child device K1 The present application can also be applied to a case in which, for example, the ringing volume in K3 is muted, for example, by an operation from the handset K1. In this case, the volume data indicating the ring volume after the setting is transmitted from the child device K1 to the other child devices K3 and K2 via the parent device T together with the data length information H indicating the information amount of the sound volume data itself. Will be.

  In the case of the above-described modification, when volume data for setting the ring volume that should be set to the same in each slave unit or the like is transmitted / received, one master unit, for example, operates another slave unit at a time. You can set the ring volume for the phone and handset.

  Furthermore, the present application can be applied not only to the setting of the ring volume, but also to the common processing of the tone of the ringing tone, the common processing of the answering message for the answering machine, and the like.
