Abstract

PURPOSE:To prevent crosstalk by providing a silent link in a push button telephone set which accomodates plural lines, and by connecting the link to each line during ringing or calling in the silent period. CONSTITUTION:Silent links 11 and 12, which ground each line substantially, are provided each independent line, and are connected with the line independently through switches 13a and 13b which turn on at the time of opening of respective silent period and calling path of the ringing tone, busy tone and dial tone from a ringing-tone generation means 7, a busy-tone generation means 8, and a dial- tone generation means 9. Therefore, the signal in the silent period of the ringing tone and busy tone can be grounded completely by the working of the silent link even if plural lines are connected to each other.

It is configured to turn on during a call, and the switch 13
a, 131] are turned on in the silent section of the ring tone generating means 7, the busy tone generating means 8, and the dialing tone generating means 9, respectively, in the silent period of the ring tone, busy tone, and dial tone, and when the communication path is opened. It is configured. That is, switch i3a
, 13b are configured to be turned on during standby and turned off during a call, as shown in FIG.
It is configured to turn on during the silent section of the dial tone. Therefore, according to the above embodiment, even if the switches 10a and 10b are both turned on by using the telephones a and 1) at the same time, the ring tone and busy tone from the ring tone generation means 7 and the busy tone generation means 8 are Switches 13a, 13 connected to the silent link 11.12 in the silent section of
Since both phones 13a and 13b are turned on, even if you are talking near phones 13a and 13b, their signals will be sent to the switches 13a and 13a, respectively.
13b, they will be grounded via the silent link 11.12, and they will almost never be able to hear each other. In addition, during the active period of the ringing tone from the call trigger 1 means 7, the busy tone generating means 8, and the busy tone, the switches 13a, ], 3b are both turned off,
Silent links 11 and 12 do not work, but in the above-mentioned sound section, the voice signal from telephone a, 1) is completely masked depending on the ring tone and busy tone, so if telephone a
, b. Even if people talk close to each other, it is unlikely that they will be able to hear each other.

る。Effects of the Invention As is clear from the above embodiments, the present invention provides a ring tone generating means, a busy tone generating means, and a dialing tone generating means in common to each line, and connects these generating means with the respective lines. Commonly connected to each of the lines through a connected switch, and a ring tone, a busy tone, from the ring tone generating means, busy tone generating means, dial tone generating means,
A silent link is connected which connects the lines individually to AC ground via a switch that is turned on during the silent section of the dial tone. Therefore, if multiple lines are ringing or busy at the same time, the ring tone generating means Even if the plurality of lines are connected to each other via a switch connected to the busy tone generating means, the silent link will completely eliminate the signal in the silent section of the ring tone and busy tone. It has the advantage that it can be grounded and that crosstalk between the lines can be completely prevented. According to the present invention, it is only necessary to provide each silent link for each line, and the overall structure has the advantage of being simple and relatively inexpensive.
