Abstract

PURPOSE:To easily confirm the number of output routes by constituting the title system so that when the number of output routes which are supplying a clock signal from a synchronizing device is set manually, it is transferred to a controller provided together with a display device. CONSTITUTION:An operating means 200 sets manually the number (n) of output routes 100 which are supplying a clock signal from a synchronizing device 1. An output route number transfer means 500 transfers the number (n) of output routes which is set by the operating means 200 to a controller 400 provided together with a display device 300. Accordingly, the number of output routes (n) which is set by the operating means 200 can be displayed on the display device 300 at any time. In such a way, the number (n) of output routes for supplying a clock signal from the synchronizing device 1 can be confirmed without spending much time and labor.

[Industrial application field]

The present invention relates to a synchronizing device that generates a clock signal that serves as a reference for the operation of an information processing system such as an electronic exchange and supplies it to each device constituting the information processing system. The present invention relates to an output route number confirmation method that allows the number of routes to be quickly recognized.

[Conventional technology]

FIG. 3 is a diagram showing an example of a conventional synchronization device, and is intended for a synchronization device that supplies clock signals to a plurality of networks that constitute an electronic exchange.

In FIG. 3, each synchronizer 1 includes a duplicated clock generator 11 (each clock generator is 11-
0 and 11-1, hereinafter the same), selector 12
and a distribution section 13.

Each clock generator 11 generates a clock signal C1k of, for example, 16 MHz, 8 MHz, or 8 kHz, which is synchronized with a reference clock signal supplied from the outside (not shown).
-1.

Each selector 12 is connected to each clock generator 11-0 and 1
Select one of the clock signals clk generated by the clock signal clk generated by the clock signal clk 1-1 and send the corresponding distribution section 13-0 or 13-
1.

The distribution unit 13-O divides the clock signal clk transmitted from the corresponding selector 12-0 into a duplicated 0
Output cables 3-00 to 3-O are connected to one network 2-00 to 2-On of the network 2 of the set, respectively.
Further, the distribution unit 13-1 supplies the clock signal clk transmitted from the corresponding selector 12-1 to the other networks 2-10 to 2-1n of the duplicated n&Il network 2, respectively. are supplied via output cables 3-10 to 3-1n, respectively.

The number of output routes (n in Figure 3) through which the clock signal clk is supplied from the synchronizer l to the network 2 varies depending on the number of installed networks 2, that is, the number of accommodated lines, etc. As described in the data showing the specifications of the electronic exchange, when the network 2 is added as the number of accommodated lines increases, the number n of output routes also increases.

When increasing the number of output routes, etc., the number n of output routes of the currently installed synchronizer 1 is required. However, in the conventional synchronizer 1, in order to confirm the number n of output routes, However, there is no other way than to refer to the document 2010, or to count the number of output cables 3 connecting the synchronizer 1 and each network 2.

[Problem to be solved by the invention]

As is clear from the above explanation, in order to confirm the number n of output routes in a conventional synchronizing device, it is necessary to refer to materials that describe the specifications of the electronic exchange, or to check the number of output routes n between the synchronizing device 1 and each network 2. The only way to do this is to count the number of output cables 3 to be connected (which would have cost a lot of time and effort).

SUMMARY OF THE INVENTION An object of the present invention is to make it possible to check the number of output routes for supplying clock signals from a synchronizer without spending much time and effort.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 is a diagram showing a synchronization device according to an embodiment of the present invention. Note that the same reference numerals indicate the same objects throughout the figures.

In FIG. 2, the output cable 3 leading to the electronic exchange network 2 is shown as the output path 100 in FIG. 1, as in FIG. 3, and the control device 400 with the display device 300 in FIG. , a central control unit 4 is shown which is connected via a common bus 5 to a display terminal 6 installed for operation and maintenance, and is the central control unit for call processing and operation management. is provided with m duplex operation switches 14 as the operation means 200 in FIG. It is being

are transmitted to the distribution unit 13 via the selector 12, respectively,
Currently, each of the output cables is supplied to nl duplex networks 2 via zero output cables 3.

In such a situation, synchronizer l to network 2
The number of output routes for supplying the clock signal clk to is n.

In such a case, for example, the constructor who constructed the electronic exchange
Of the m operation switches 14 provided in the synchronizer 1, only n operation switches 14-00 to 14-On and 14-10 to 14-1n are operated.

Note that the number m of operation switches 14 is equal to the maximum number of output routes to which the distribution section 13 can supply the clock signal clk.

As a result, each of the operated operation switches 14-00 to 14-O is stored in each register 15-0 and 15-1.
The ground potential is supplied through the terminals n and 1.4-10 to 14-1n, and the number n of output routes is stored in the registers 15-0 and 15-1, respectively.

In this state, if it becomes necessary to check the number n of output routes of the synchronization device 1, the maintenance person operates the display terminal 6 and manually inputs a command to confirm the number of output routes.

When the central control device 4 receives a command for confirming the number of output routes inputted from the display terminal 6 via the common bus 5, the central control device 4 controls one of the control sections (for example, one
6-0), transmitting a control signal requesting an answer of the number of output routes.

In the synchronizer 1, when the control unit 16-0 receives a control signal requesting an answer of the number of output routes, the register 15-0
, extracts the accumulated number n of output routes, and sends it to the central controller 4.

The central control device 4 transmits the number n of output routes answered from the control section 16-0 in the synchronization device 1 to the display terminal 6 via the common bus 5, and displays the number n.

The maintenance person can confirm the current number n of output routes by visually checking the number n of output routes displayed on the display terminal 6.

As is clear from the above description, according to this embodiment, the number n of output routes through which the synchronizer 1 is currently supplying the clock signal clk to the network 2 can be set by operating the operation switch 14. Therefore, when a maintenance person inputs a command for confirming the number of output routes from the display terminal 6, the number n of output routes can be immediately displayed on the display terminal 6.

Note that FIG. 2 is only one embodiment of the present invention, and for example, the load to which the synchronizer 1 supplies the clock signal clk is as follows:
The present invention is not limited to the illustrated network 2, and many other modifications may be considered, but the effects of the present invention remain the same in either case.

Further, the operating means 200 for setting the number of output routes is not limited to the illustrated operating switch 14, and many other modifications may be considered, but the effects of the present invention remain the same in any case. Further, the output route number transfer means 500 that transfers the number of output routes includes a register 15 and a control unit 16 shown in the figure.
Although the present invention is not limited to this and many other modifications may be considered, the effects of the present invention remain the same in any case. Furthermore, a synchronization device ff! which is an object of the present invention! It goes without saying that 1 is not limited to what is illustrated.
