た所へ設置してしまうような危険もある。 Conventionally, a plurality of synthesizer-type communication devices (transmitters and/or receivers) used in base station radio equipment are installed in the same device, and each transmitter or receiver has a local oscillation synthesizer, It has a read-only memory (ROM) in which device-specific channel numbers are written and a channel designation circuit. The channel designation circuit reads the device-specific channel number from the ROM, sets the local oscillation synthesizer to the corresponding frequency, and designates the channel. If your transmitter or receiver fails and you want to replace it with a spare transmitter or receiver,
Each communication device has its own ROM, so replacing it requires a lot of man-hours. Furthermore, when maintaining multiple units, there is a risk that the transmitter or receiver may be installed in the wrong location.

For the mth (1mn) transmitter or receiver,
By transmitting data of channel number a n from the control circuit and setting the synthesizer of the m-th transmitter or receiver to the frequency corresponding to the channel number a n , the channel number of the transmitter or receiver is set.

1 shows a base station receiving device in which three receivers are mounted. In the figure, receivers 1 to 4 are receivers installed in the device, a control circuit 5 is a circuit that controls the channel designation operation of each receiver, and a ROM 6 contains the channel number a o ( n=1, 2,...

信機１〜４に所定のチヤネルを設定する。 When the device is powered on, the control circuit 5 reads the channel number a 1 from the ROM 6 and sends it to the first receiver 1.
It is sent as channel number data D8. Receiver 1 sets its internal synthesizer to the frequency determined by channel number data D8, and starts receiving operation at the corresponding frequency. moreover,
The control circuit 5 reads the channel number a2 from the ROM 6, sends channel number data D9 to the second receiver 2, and sets the channel of the receiver 2. Similarly, up to the 16th receiver 4,
Channel number data is sent and predetermined channels are set in all receivers 1 to 4 in the device.

部のシンセサイザを設定し、受信動作に入る。 Next, a case where a failure occurs in the m-th (1mn) receiver 3, for example, will be described. When a failure occurs in the receiver 3, a maintenance person removes the receiver 3 from the device and installs a spare receiver having the same structure as the receivers 1 to 4 in the position of the receiver 3. Due to the cyclic channel designation operation of the control circuit 5, the standby receiver receives the channel number data D10 within a predetermined time, sets its internal synthesizer to the frequency corresponding to the channel number a n , and enters the reception operation.

できるという利点も生じる。 In the conventional method, a maintenance person removes the receiver 3 from the device, removes the ROM inside the receiver 3 in which the channel number a n is written, installs this ROM in the backup receiver, and then installs the backup receiver into the device. The procedure was to implement it and recover from the failure. In contrast, according to the present invention, the backup receiver can operate on the channel corresponding to the channel number a n simply by mounting the backup receiver at the m-th position. Therefore, according to the present invention, maintenance can be significantly simplified. In addition, receiver 1 currently in use
Similarly, in 4, the channel number can be determined depending on the position where the receiver is installed in the device, so even if the receiver is installed in the wrong position, the device can still operate normally.

も、同様な効果が得られることは明らかである。 In this embodiment, a case has been described in which one control circuit controls 16 receivers, but the number of control circuits included in one device and the number of receivers controlled by one control circuit are arbitrary. Therefore, it is also possible for the range controlled by the control circuit to extend over other devices. Furthermore, it is clear that similar effects can be obtained even if this embodiment is applied to a transmitting device.
