Description

Detailed Description of the Invention (1) Technical Field of the Invention The present invention relates to a system in which subscriber lines are connected to a digital exchange by concentrating and multiplexing them in a first line device d, in which analog subscriber lines mixedly accommodated in the concentrator are Both subscriber circuit and digital subscriber circuit;flt:I? Subscriber circuit that enables Ku! This relates to the I control method.

(2) Conventional technology and the point between subscribers] In order to improve the efficiency of implementing subscriber lines when pulling in a wharf, it is necessary to concentrate the lines into multiple pieces via a cotton collecting rd and connect them to the highway and connect them to the exchange. is being carried out.

This subscriber line has one analog subscriber line and one digital subscriber line connecting the analog subscriber terminal and the digital subscriber terminal. Rather than providing a line concentrator 6 that accommodates digital subscriber terminals independently of the eastern line equipment that accommodates subscriber lines, a system 7 line that accommodates a mixture of analog subscriber lines and digital subscriber lines in the same line concentrator is preferred. , it is also economically advantageous.

However, if this mixed accommodating system is adopted, the line concentrator must control both the analog IJO input route and the digital subscriber circuit, which interface the analog subscriber line and digital subscriber line, respectively. ili to 11i11 fall each subscriber circuit! A system 1i111 memory for storing I@115 must be provided for the analog subscriber circuit and the digital subscriber circuit, respectively. However, providing a memory for each subscriber circuit means that the subscriber circuit control information sent from the middle floor control device on the exchange side differs between analog subscriber circuits and digital subscriber circuits. It is necessary to control 1t (one antiperspirant order for storing IV information in a dedicated memory), and the number of digital subscriber terminals and analogue IJ users will be increased. There are problems such as the need to provide the maximum capacity of each control memory in order to cope with fluctuations.

(3) Purpose of the Invention In order to solve this problem, the present invention provides a common control memory for controlling the subscription input IWj in the analog subscriber circuit and the digital subscriber circuit, so that the same Subscriber circuit side part 1 that allows analog subscriber lines, digital subscriber lines, and groups to be accommodated in a mixed manner.
The purpose is to make the method more precise.

Note that S is a signal line for controlling the subscriber circuit, and T is a signal line for audio data. In such a system configuration 1', the present invention allows the subscriber circuits al+a2 to be connected by the same control means to concentrator switches rather than to analog subscriber circuits and digital subscriber circuits, respectively. Each subscriber circuit is defined as a control station fiB, and will be explained in detail below with reference to FIG.

Reference numeral 2171 shows a specific configuration of the control circuit i% of the line concentrator d in FIG. 1, and in particular, only the control circuit component of the subscriber circuit according to the present invention is shown. In the figure, 5 is a control signal storage circuit for initializing the analog subscriber circuit;
6 is a control signal storage circuit for initializing the digital subscriber circuit, 7 is a control signal storage circuit for system initialization, and 8 is a control for initializing the digital subscriber circuit when the system goes down. A signal storage circuit, 9 is a control signal storage circuit that controls subscriber circuits sent from a central control unit, etc. during exchange processing, and 10 is a number of a subscriber circuit when controlling subscriber circuits during exchange processing. In the storage circuit, this number information corresponds to the address corresponding to the subscriber circuit in the control memory 19, as will be described later. 11.12.

An input terminal for indicating the presence or absence of command information, 18 is a read/input timing signal for the ttit control memory 19, and 17 is an output terminal for a control signal sent to the subscriber circuit. This control signal 17 is distributed and output to the signal line S in FIG.

The control memory 19 basically has addresses corresponding to subscriber circuits and stores control signals to each subscriber circuit, and at the time of initial setting of the system, when the system goes down, etc.

f: Write the contents pointed to by the counter 15 into the control memory 19 as an address.

In addition, the subscriber circuits required for the exchange process are controlled by software, such as a control signal storage circuit 9 and a number storage circuit 1.
By setting it to 0, the contents of this stored fη are written into the control memory 19.

On the other hand, the subscriber circuits are controlled by sequentially reading out the contents of all addresses in the control memory 19 by the counter 16 and distributing the output of the control signal 17 to each subscriber circuit.

Based on the input signal of the input terminal 4, the selector 12 selects the storage circuit 9, and the selector 14 selects the storage circuit 1o, and a write signal is sent to the memory 19 under the timing signal 18 and the input signal 4 under the AND condition. By selecting the selectors 14 and 13, the number information is set as an address for the storage circuit 10, and the control signal (9) is set to 1 via the selector 12 at the corresponding address.

This control signal is different for analog subscriber circuits and digital subscriber circuits, but it is due to the difference in parameters.
The control signal to be sent and the type of subscriber circuit (analog/digital) are determined by the central controller q:
It is possible to control analog/digital access circuits by simply sending the same control command from the cc, that is, number information corresponding to an address and a control signal.

In addition, when initializing all subscriber circuits (system down, etc.), input terminal 3 is activated and writing to the memory 19 is possible, and the write address of the memory is set to the selector because input terminal 4 is not activated. 14 selects the output of the write counter 15. Also, since input terminal 2 is not activated, the write information for memo 1J19 is sent from the one designated for storage 5 and 6 by selector 11゜12 according to analog/digital switching information (1). Read out as a fixed pattern. Since the outputs of the counter 15 and the input terminal 1 are the same JU1, the initial setting signal of the analog/digital subscriber circuit is written to the door 1 at the address ↓h of the counter 15. Incidentally, when the initial setting values of the storage circuits 5 and 6 are performed by a command from the central control unit cc, the initial setting signal of the storage ffF circuit 5.6 can also be set at the time of sending the initial setting command of the line concentrator. 〇When the system goes down, the counter 15 is set as the memory's ■inclusive address, and the counter 15 is set to select 1-, and the memory's 1!1 is manually activated to the input terminal 2. Since the gate is crossed, the selector 11.12 reads out the +1 signal at the time of system down from either the storage circuit 7 or the storage circuit 8, and outputs the analog/digital output.
One initial setting word is written for each 01 path.

It should be noted that the wire concentrator t';/ of the present invention shown in the figure is an actual example, and it goes without saying that various modifications can be made.

According to the embodiment of the present invention, it is possible to share the subscriber circuit control memory that stores the subscriber circuit I[il control signals, and to reduce the hardware 14 by using the same control command from the central processing unit. Both analog and digital subscriber circuits ii+! Since the I/IJ code can be loaded into the control memory, the number of software interfaces can be reduced. In addition, initial settings.

When the system goes down, ii+ll fit into the subscriber circuit control 11 memory for analog and digital subscriber circuits.
Since a means for receiving the +1 signal is provided, even if analog and digital devices share the full ifU memory, control numbers 11 and 11 can be written to all addresses in one operation.

(6) As described in 7h of the detailed description of the invention, the invention provides that both analog subscriber circuit and digital subscriber circuit signals can be stored in the same memory, and each subscriber circuit can be mixed with a line concentrator. It is possible to accommodate the amount of hardware, medium heat control wholesale equipment, etc.
It is possible to set the flill 1 signal during initial setup without increasing the number of ll 4 + tl commands, etc., and without doing analog/digital %T, a(j!).
