2. Description of the Related Art Conventionally, as shown in FIG. 2, the collective entrance machines EQ ₁₁ and EQ ₁₂ with a room number registration function have a 2-wire to 4-wire converter 2, a downstream amplifier 3, and a speaker 4. ,
A communication circuit 1 provided with a microphone 5 and an up amplifier 6, a communication path switch 7 formed by normally open contacts, a channel selection signal transmission circuit 8,
It is composed of a numeric keypad 9, a room number memory 10 and a CPU 21.

Group entrance machines EQ ₁₁ and EQ ₁₂ with room number registration function
The call terminal T ₁ and T ₁ of the is connected to the line L _1, L ₁ a set entrance machine exchange EX, the other contact of the channel switch 7 one contact of which is connected to the call terminal T ₁ is speaking circuit 1 2 wire terminal 1a. Also, the two-wire terminal 1 of the call circuit 1
4 of the 2-wire 4-wire converter 2 in which the 2-wire side terminal 2a is connected to a
The line downlink terminal 2b is connected to the speaker 4 via the downlink amplifier 3. Further, the microphone 5 is connected to the four-wire ascending terminal 2c via the ascending amplifier 6. In addition, the 4-line up terminal 2c is connected to the tuning signal terminal 1b, and the tuning signal terminal 1b is the CPU.
It is connected to the outgoing side of the tuning signal transmitter 8 controlled by 21.

The control side of the communication path switch 7 and the output side of the numeric keypad 9 are connected to the CPU 21, and the room number memory 10
Is connected to the CPU 21 via the data bus 10a.
From the numeric keypad 9 of the collective entrance machine with a room number registration function EQ _{11 having} one of the above-mentioned configurations, # 123 is sent to the CPU 21 for room number registration, and # is a memory identification code for the room number memory 10, and the # code is not added. Room number memory 1 when digit 123 is pressed
If the digit number 123 stored in 0 is reproduced, the CPU 21 identifies the input # 123 and stores the digit number 123 of the room number in the room number memory 10.

Here, the visitor operates the ten-key 9 with the other collective entrance machine EQ ₁₂ with a room number registration function to select a channel number 123.
Is sent to the CPU 21, since the room number memory 10 does not store the room number digit 123, the channel selection signal transmitter 8
The channel selection number 123 is not transmitted from. However, when the visitor operates the numeric keypad 9 on one of the collective entrance machines with the room number registration function EQ ₁₁ and sends the channel selection number 123 to the CPU 21, C
In the PU 21, the digit number 123 of this room number is the room number memory 10
It is determined whether or not the room number is stored in the channel number. Since it is stored, the communication path switch 7 is closed and the digit number 123 of the room number is transmitted to the channel selection signal transmitter 8. The channel selection signal transmitter 8 transmits the inputted digit number 123 of the room number to the 4-line up terminal 2c of the 2-line to 4-line converter 2 via the channel selection signal terminal 1a of the communication circuit 1.

The exchange EX for the collective entrance is a channel number 123
Selects a room unit (not shown) to call between the room unit and the call circuit 1 and perform a call path connection operation. As described above, the room number memory 1 of the collective entrance machine EQ ₁₁ with one room number registration function
Even if the room number 123 is stored in 0, the room number 123 is stored in the room number memory 10 of the other collective entrance machine EQ ₁₂ with the room number registration function.
Is not remembered, perform the same room number registration operation using the numeric keypad 9
There are some inconveniences in the procedure for registering the room number, such as having to be done in. Therefore, there are problems that the room numbers stored in the room number memory do not match and the operability at the time of changing the registration is deteriorated.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and is a room stored for registration in a room number memory of all collective entrance machines with a room number registration function connected to a collective entrance switch. It is an object of the present invention to provide a collective entrance machine with a room number registration function that can improve the operability when matching numbers and changing registration.

[0008]

A collective entrance with a room number registration function of the present invention is a room for at least two stations connected to a switch for a collective entrance and having room number memories for storing and reproducing room numbers. When a room number is stored in a room number memory of one room number registration function-equipped collective entrance machine, the room number is stored in the room number memory of another room number registration function-equipped collective entrance machine. It is provided with a room number registration data transmitting / receiving circuit for sending and storing, and a channel selection signal sending circuit for sending the room number reproduced from the room number memory to the switch for collective entrances.

[0009]

When the room number is sent from the numeric keypad to the CPU for registering the room number, the CPU stores the room number in the room number memory. When the room number transfer button is pressed, the room number stored in the room number memory is reproduced by the CPU and sent to the room number registration data transmitting / receiving circuit. The room number registration data transmission / reception circuit sends the input room number to another room number registration data transmission / reception circuit via the data line.

If the room number generated by the ten-key pad at the time of channel selection matches the room number reproduced from the room number memory, a channel selection signal is transmitted from the channel selection signal transmitter.
