い場合が生じる等の欠点があつた。 Conventionally, the connecting portions of this type of command telephone device differ depending on the command line type, but even when two lines of the same line or different types of lines are connected, they are only connected to the same point. Therefore, in the above-mentioned system with different line configurations, it is necessary to adjust the amplifier (speech/signal level) according to each line (each line has a different line loss, etc.), and it takes time to adjust the equipment installation. , maintenance is also complicated. In addition, even on the same line, line losses and other factors differ depending on the system, so there are drawbacks such as the quality of calls (particularly the volume) may not be the same.

The purpose is to provide a connection circuit that distributes the communication to each other and makes the call quality the same.

This amplifier AMP is used to adjust the signal/audio level of each line, and the setting values for each line are the same. The receiving section includes a signal receiving unit PEC provided corresponding to the receiving line of the command console. The connection section includes a line distributor (wire ring) that is connected to the transmission side line of the command console and distributes the signal to each command line system (in this example, two systems), and a line distributor that combines the signals of each command line system. It is equipped with at least a line coupler (wire ring) for sending out to the receiving side line of the command center, and an amplifier AMP provided respectively corresponding to the transmitting and receiving line of each command line system, and furthermore, the command line has two lines. In the case of the type, a hybrid circuit is provided for transmitting a transmission signal from the command console to the command line and for transmitting a transmission signal from the command line to the command base. This configuration allows it to correspond to the configuration of the command line.

対し1系統は2線に変換し、また他系統に対して

合は送受話路共4線に変換し2方向に分配する。 For example, in the case of the #1 round of a two-wire command line, the transmission side line of the command console enters the connection unit via the reception unit, is distributed in two directions by the line distributor, and the transmission line of each system is becomes. Similarly, after the output of the amplifier AMP, the receiving line of each system is coupled to one command console receiving line by the line coupler.
At this time, since the #1 line is a 2-wire system, it is used for transmission,
Each of the receiving amplifiers AMP is connected via a hybrid circuit. If the command line is a four-wire type, this hybrid circuit is not necessary. Line transmission loss (line loss + telephone insertion loss) differs from system to system, so an amplifier is installed in the transmitting and receiving line, and the level is set by the amplifier according to each line, so that the same level is achieved at the repeater section. Further, in the case of #2 round, one channel of the transmission/reception channels distributed in two directions is converted to 2 wires, and the other channel is connected with 4 wires. Furthermore, in the case of the final line #3, both the transmitting and receiving channels are converted to 4 lines and distributed in two directions.
本発明は、以上説明したように指令電話装置と
