Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a signal conversion system, and more particularly to a signal conversion system that multiplexes line signals and enables remote control.

[Conventional technology]

Conventionally, the signal conversion method used in telephone exchanges sends and receives line signals using a conversion circuit installed for each communication path.
The method was to convert this into the signal format of each of the two telephone exchanges connected.

[Problem that the invention seeks to solve]

In the conventional signal conversion method described above, each call path is independent and controlled individually, so there is no centralized monitoring function at the master station, and because a conversion circuit is provided for each call path, the overall device The problem is that the size of the system increases.

An object of the present invention is to provide a signal conversion method that facilitates centralized monitoring and remote control at a master station, improves reliability, and is economical.

[Means for solving problems]

The signal conversion system of the present invention is a signal conversion system in which line signals from two telephone exchanges with different signal systems are received and mutually converted. The master station multiplexes the line signals of each of the plurality of communication paths with the slave station, and controls the line signals of each of the plurality of communication paths based on information from the central control device of the master station, and simultaneously controls the line signals of each of the plurality of communication paths with the slave station. A master station side control device is provided which has the function of monitoring and controlling the slave station side control device included in the signal conversion device installed in the station and the trunk, and the slave station has the function of monitoring and controlling the slave station side control device and the trunk. A function of converting the line signals of each of the plurality of multiplexed communication paths connected through a trunk line into the signaling system of the telephone exchange of the slave station and redistributing them to each communication path; A function of converting each line signal of each communication path into the signaling system of the telephone exchange of the master station, multiplexing it, and sending it to the master station, monitoring the operation of the trunk of each communication path, and transmitting the results to the control device on the master station side. A slave station side control device having a function of receiving control information sent to the trunk and controlling the trunk is provided.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention.

FIG. 1 shows a case where the master station is a time division telephone exchange 1 and the slave stations are a space division telephone exchange 2. The inter-office trunk line 4 between the time-division telephone exchange 1 and the space-back division telephone exchange 2 is used exclusively for voice, and the inter-office trunk line 5 uses one channel of the telephone trunk line exclusively for line signals. ing. The central control device 6 of the time division type telephone exchange fil sends line signals of each of the plurality of communication paths to the space division type telephone exchange 2 to a trunk line signal device or a common line signal device in normal operation of the exchange. However, in this embodiment, it is sent to the master station side control device 7. The master station control device 7 multiplexes the received line signals and sends them from the time division connector device 8 to the slave station control device 10 via the time division communication path device and the inter-office II line 5. The slave station side control device 10 receives the multiplexed line signals, separates them into individual line signals, performs signal conversion, and then distributes them to the corresponding trunks 11 and 12.

Also, from the space-back type telephone exchange 2 to the time-division type telephone exchange 1
The line signal to the slave station enters the slave station controller 10 from the trunk 11, 12, and after signal conversion is performed by the slave station controller 10, it is multiplexed and sent to the inter-office trunk line 5, the time-division channel device, and the time-division connector device. 8 and is sent to the master station side control device 7. The master station side controller 7 separates the received line signals for each communication path and sends them to the central controller 6 for control of each communication path.

The slave station controller 10 constantly monitors the trunks 11 and 12, and if there is a change, sends a monitoring signal to the master station controller 7 through the same route as the line signal. When the master station controller 7 receives a monitoring signal from the slave controller 10, it transfers it to the central controller 6 and waits for an instruction from the central controller 6. The central control device 6 performs processing corresponding to the received monitoring signal and ranks 1 to 11.1.
2 is sent to the master station side control device 7. At the same time, if the received monitoring signal is abnormal, the central control device 6 issues an alarm to the outside to inform the maintenance personnel. The master station control device 7 sends the received control signal to the slave station control device 10 through the same route as the line signal.

The slave station controller 10 controls the corresponding trunk 11, 12 in accordance with the received control signal.

〔Effect of the invention〕

As explained above, the present invention aggregates the signal conversion functions of the signal conversion device and multiplexes the signals, thereby simplifying the trunk circuit and making the equipment installed in the slave stations more economical. This has the effect that remote monitoring and remote control of the signal conversion device at the station becomes possible.
