BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a level diagram remote control system for an entire network in an information network in which a plurality of stations are connected by high-speed digital lines.

0002

[Prior Art] Conventionally, the level adjustment of transmission signals in time division multiplexing equipment has been set using switches using mechanical contacts, and when adjusting or changing the level between stations, a dedicated engineer is required to do so on-site at each station. Up to that point, I had gone there each time and set the level.

0003

[Problems to be Solved by the Invention] The above-mentioned conventional setting of signal levels between multiple stations uses mechanical switches, so it is difficult to check the current status of the network or change the settings of the signal level diagram caused by changes. However, there is a drawback in that a dedicated engineer must travel to the site each time to perform the operation. Furthermore, if the network configuration is changed many times, the management of level setting data between each station becomes confusing, making it difficult to design and set a level diagram in the event of an addition of stations or a failure.

An object of the present invention is to provide a level diagram remote control system that allows remote control of signal levels between a plurality of stations and terminal equipment connected by high-speed digital lines.

[0005]

[Means for Solving the Problems] The level diagram remote control system of the present invention is applied to an in-house information network in which multiple stations equipped with time division multiplexing devices accommodating multiple terminal devices are connected via high-speed digital lines. A specific station among the plurality of stations is provided with a central management device that manages the network,
The central control device sends a command signal to adjust the signal level of a signal transmission/reception port between the time division multiplexing device installed at each station and the terminal device accommodated by the time division multiplexing device. shall be.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a network configuration diagram showing one embodiment of the present invention, and FIG. 2 is a block diagram showing one embodiment of the present invention.

The network shown in FIG. 1 is a high-speed digital network that interfaces telephone terminal devices 1-1, 1-2, time-division multiplexers 10, 20, and high-speed digital line 5. Line termination device 3-1, 3-
2, and a central monitoring device 4 that manages the entire network.

The level diagram remote control system shown in FIG.
A time division multiplexing device 1 that multiplexes voice signals from a plurality of telephone terminal devices and transmits the same via a high-speed digital line 5, and separates the received voice multiplexed signal and sends it to the telephone terminal devices.
0 and 20, control units 11 and 21 that receive command signals sent by the central monitoring device 4 that manages the entire network, convert them into predetermined signals, and control level adjustment circuits 13 and 23, audio amplification circuits 12 and 22, and high-speed It is composed of high-speed digital line termination devices 3-1 and 3-2 that interface with digital lines and time division multiplexers 10 and 20.

[0010] Here, an explanation will be given by taking as an example the setting of the audio input signal level of the time division multiplexing device 20 from the central control device 4 via the time division multiplexing device 10.

Audio signals input from a plurality of telephone terminal devices are input to input level adjustment circuits 13-1, 13-2, 13-
n, each is adjusted to a predetermined level, and then amplified to a predetermined level by the audio amplification circuit 12, and then sent to the multiplexing/demultiplexing circuit 1.
4 is input.

Input level adjustment circuits 13-1, 13-2,
13-n operates in response to the time division multiplexer control section 11.

When the central management device 4 inputs a command signal for setting an input level to the time division multiplexing device control section 11, the command signal is transmitted to the time division multiplexing device control section 11.
The signal is input to the multiplexing/demultiplexing circuit via.

The multiplexing/separating circuit 14 includes the audio amplifying circuit 12
The output and the input command signal are multiplexed and sent to the multiplexing/demultiplexing circuit 24 of the time division multiplexer 20 via the high-speed digital line termination device 3-1, the high-speed digital line 5, and the high-speed digital line termination device 3-2. Enter.

The multiplexing/separating circuit 24 separates the audio signal and the command signal, and the audio signal is input to the audio amplifier circuit 22 and the command signal is input to the time division multiplexer control section 21, respectively.

The time division multiplexing device control unit 21 generates control signals in response to individual command signals, controls the level adjustment circuits 23-1, 23-2, and 23-n, and performs time division multiplexing. The audio signal level from the telephone terminal device input to the device 20 is adjusted to a predetermined level.

[0017] In this way, differences in call levels between subscriber lines and individual telephone terminal devices connected to each time division multiplexing device are controlled from the central control device, and voice call levels between telephone terminal devices are uniformed to a predetermined level. to improve call quality.

The level adjustment circuits 13-1, 13-2, and 13-n of the time division multiplexing device 10 are similarly controlled by the central management device 4. Furthermore, in the above description, the command signal was multiplexed with the voice signal and transmitted, but it is also possible to adjust the level using the command signal in a non-call state.

[0019]

[Effects of the Invention] As explained above, the present invention enables the setting of the signal transmission/reception level between multiple stations to be performed by a network monitoring station using a command operation based on a personal computer, so that the current status of the signal level of each local station can be grasped and the settings can be changed. It is easy to perform and has the effect of eliminating the need for engineers to visit the site each time the work is performed. It also has the effect of shortening the construction period for new station installations and changes.
