Abstract

PURPOSE:To improve the processing efficiency of an attachment, by eliminating the need to hold a circuit exchange between the 1st starting and the generation of the 2nd start signal. CONSTITUTION:A terminal 101 connect a clocking device 305 for holding the starting of a main power source 302 to a controller 303 for a specific time even when no signal to the attachment 103 is detected. Then, the main power source is turned on to hold the terminal in readiness for receiving a re-call signal from a network 102. If the re-call signal is detected during this period, the terminal 101 starts terminating operation. On the other hand, when the attachment 103 actuates the terminal 101 once to send a call signal and if there is no answer in this case, it is restarted a specific time later to send the re-call signal.

Description

[Detailed Description of the Invention] When the present invention is started, the program is stored in an external memory and starts loading into an internal memory.
Wait for the end of loading and then start normal operation. It is related to Myodou Fou 2.

Conventionally, it was a companion terminal for one microcomputer,
Since computers operate using large-scale programs or variable programs, terminals designed to control other terminals (for example, the above-mentioned Teletex) use a ROM (read-only) that stores the boot program. (Memory) It is not convenient to use Kllll contract memorization because it is disadvantageous in terms of programming.The program is stored in an external memory such as a floppy disk, and when used, the program is stored in an external memory such as a floppy disk. A method is adopted in which the program is downloaded from the computer to internal memory (RAM) and used.

If the main power of the terminal is always on (always on) and the program is stored in the internal memory and always running, the terminal will be able to start up and operate immediately when it is requested to start up. , to round it off, the main power must be kept on even when the terminal is not operating,
Since it consumes a considerable amount of power and is uneconomical, normally nine hardware circuits are added at the end of the circuit in preparation for detecting calls from the line-switched network. A method has been adopted to keep it alive with a small power source. When the aforementioned hardware circuit detects a call from the circuit-switched network side, it turns on the main power supply and turns on the external memory stored in the 51 external memory such as the zero-flop disk. No, the program is loaded into the internal memory (RAM), and after the loading is finished, it runs normally.

Such terminals have the advantage of low power consumption and large energy-saving effects in non-over-reliable networks where they do not communicate with the switched network side, but they are 0! EW is located on the line-switched network side and starts up the terminal. From the point of view of the O-additional device or other terminals, K is external until the terminal suddenly boots up and starts operating even if it is started up. It takes about 10 seconds to load the program from memory into the internal memory, and during this time the line is put on hold and the processing functions of the attached device are disabled. The darkest period will be occupied as necessary, and by additional equipment, &II
& Rui The disadvantage is that the decline in efficiency makes it impossible to make money.

For example, according to the regulations of the DDXgil line switching network, the target terminal here is an automatic response device that starts up within o, s seconds after startup.
This is a terminal that belongs to the manual response class, which allows startup up to seconds. If you want to use a terminal that belongs to the automatic answering class, you can put the program in ROM, keep the main power on at all times, run the program, and immediately respond to calls from the exchange network. I explained to the company that this would increase the cost of the device and was not good in terms of energy conservation.

The present invention is intended to eliminate the above-mentioned shortcomings in terminals belonging to the manual response class as described above. We would like to provide a terminal startup method that minimizes the hold period of the line switching network at the time of use, and that allows for improved processing efficiency using additional equipment.

In short, the configuration of the present invention is that when it is started, it starts loading the 9 programs stored in the external memory to the internal memory, waits for the end of loading, and then starts normal operation. This is an activation method from the circuit switched network side, and the switched network side includes a first activation signal sending means and a 5-incoming call rejection signal from the terminal side when the first activation signal is sent. If there is no response from the terminal, after a predetermined period of time has passed,
and means for sending a second activation signal, and on the terminal side,
means for returning the incoming call rejection signal to the switching network side upon receiving the first activation signal from the switching network side, or for starting p-loading of the program into the internal memory without responding; and a means for waiting for a second activation signal from the network side and transitioning to incoming call operation when the second activation signal is received within a predetermined period, and after receiving the activation signal #g1, the second activation signal is activated. The terminal startup method is characterized by eliminating the need to hold the circuit-switched network until the terminal is activated.

The present invention will now be described in detail with reference to the drawings.

FIG. 1 is a conceptual diagram showing an example of a system configuration of a terminal activation method to which the present invention is implemented.

This figure shows how the network 102 makes a call to the terminal 101 to activate the additional device 103 of the network, and how another terminal 104 makes the call via the network 102. As shown in the following, the present invention is mainly directed to the case where the terminal 101 is started up from the additional network equipment [103] via the network 102, but it may also be started up from another terminal 104. Of course.

FIG. 2 is a block diagram showing the configuration of the terminal-side folding section in one embodiment of the present invention. In the figure, 301 is a call detection path including an auxiliary power supply that is turned on in case of an emergency, 302 is a main power supply,
303 is a control circuit including a memory, 304 is an external memory such as a floppy disk, and 305 is a clock device.

FIG. 3 is a time chart of signals of various parts when the terminal shown in FIG. 2 is just starting up, and when the terminal is about to cross one island.

The operation will be explained with reference to FIGS. 2 and 3.

The terminal 101 in FIG. 2 is used to initialize the network circuit 303 in the call detection circuit 301 including the always-on auxiliary power supply, and to start up a storage medium consisting of an external memory 304 such as a floppy disk. It takes several seconds, and then the program is loaded from the external memory 304 to the control circuit 30B.Once these are completed, loading usually takes 10 seconds, depending on the location. .

In conventional terminals, the main power is turned on either by turning on a terminal switch (not shown) operated by an operator or by a call from the network 102. If the control path 303 determines that none of these conditions apply, the startup of the Toryu IIO is assumed to be 10 due to some malfunction, and the Toryu 11802 is immediately activated.
OFF, the bootlam running also stops. That is, in the 3rd II, ■-ding ends and the terminal starts running normally, and at the point of death, as shown by the arrow, OW from the rope! Check the presence or absence of the P output detection signal 0, and if it is - (yap, the above-mentioned 0 switch is not turned on by operator operation),
Immediately bring down the Earth Dragon.

However, in the present invention, even if no call signal is detected by IIL determination with the rope attachment device 103, after a predetermined period of time,
Terminal 101 maintains the startup of Doryu $1302.
A timing device 30B is provided to the control enclosure 303, for example, a wrinkle timing device 30! If I is 10 seconds, turn on the main power while counting 10 seconds, and make sure the terminal is running normally.
1KL, and waits for a re-call from the network 102. If a re-call is detected during this time, that is, as shown in the arrow 0 in 83, the terminal 101 #
i Shift to incoming call operation. Note that the predetermined time measured by the clock device SO5 is at least as long as
From external memory 304 to control path 303. P. -0
It is necessary to allow at least the time it takes for the terminal 101 to start up at any time after the end of the day and the terminal 101 to reach the state 11.

On the other hand, the cable attachment device 103 regards the terminal 101 as a terminal belonging to the automatic response class and sends a call signal for a short period of time by applying a 1fjil operation, even if startup is not completed because the terminal does not respond. 70＠ Start loading the program on the terminal side, wait until the loading is finished and you can get back to work, then start it up again and send a re-call signal.

The tie-building process by which the additional device 103 sends out this recall signal will be explained with reference to the fourth wJ.

There are probably many terminals connected to the cable, but among them, the longest time is the time from when the program starts loading until it is completed and can be started up at any time. Select the terminal ■ that requires tl and the terminal ■ that takes the shortest time t2. After the elapse of 11 hours, the previous terminal ■ continues to turn on the main power and wait for 4t1, and the terminal Similarly, when (1) is still set to turn on the main power supply and stand by after 18 hours have elapsed, and the dead time is Δt2, the additional device 103 starts the second time (t20). It will be understood by those skilled in the art that it is necessary to multiply the difference between In any case, it is a short-term arrangement of no more than a minute.

Also, in many terminals, the above '1 * 'l *Δ'
1. If the time to ejt3 varies from place to place, the additional device 103 will be used for 3 times, 4 times, etc.
Then, you can do a 5K run by starting at certain intervals.

Referring again to FIGS. 2 and 3. In accordance with the synchronous regulations of the DDX-enhanced switching network, the terminal 101ti additional device 1110
Upon detection of the first call from 3, the call detection circuit 30 should respond automatically within 0.5 seconds as shown in FIG.
1 to CNR (Control Otori sd not r@a
dy ) signal (call rejection signal indicating that calls cannot be received at this time)
may be returned to the additional device 103 and continued until the control circuit 303 completes initialization and loading, and then the normal incoming call operation may be started upon subsequent re-calling. This eliminates the need for the initiating side 0 network 102, the cable O addition device 1 GB, and other terminals 104 to treat the called terminal 101 as abnormal because it does not respond, and the "call rejection" specified in DDX is avoided. It is treated as

In addition, not only the network additional device 103 but also other terminals 104,
It is also possible to realize the activation of the terminal 101 as a restart tin based on the response of the 4DCNR from the terminal 101.

Note that the CNR signal is transmitted to the call detection path 301 during non-communication.
Even if it is configured to send from the line 102, the call detection edge described above does not need to be used since only the call is made from the line 102.

As shown in FIG.
Calling terminal B and displaying the seven functions of terminal B or terminal B
You may check yourself.

At this time, the additional device activates the terminal BO twice in accordance with the spirit of the present application as shown in ■ and ■. The call from the device is determined to be a welcome call, and when waiting for the next second call, the main power is not turned off and the device waits for the call again. The above clocking device 305 may be used to reset the clock to the time value required for waiting for the second call.

If the number is set to 5, terminal B can immediately respond to the second call. At the end of this second call, the timing device 3
Immediately turn off the main power without operating 05,
All you have to do is shut down terminal B. In this way, the timing device 3080 can be used not only to simply stand up and set a short time when the rising condition is no longer present, but also to set the timing for the next call at a predetermined time for the first call as in this example. It is also possible to wait for two calls.

In this example, CCITT Recommendation F, 20G telex and teletex interconnection is supported, the terminal person is compatible with telex, and the terminal B is compatible with teletex.

As explained above, according to the present invention, the network additional device 1
03 treats the terminal 101 as a terminal that belongs to the automatic response class, and if a response appears in response to the activation, if it is a response of the makushi cNR signal, it will activate again within a short time. Just do it like this. The terminal 101 is made to belong to the manual response class, and even after the device is started up in response to a call from the network 102, for a short period of time, the terminal 101 is not judged to have started up due to malfunction even if there is no reason for it to start up. The startup is continued, and the incoming call is processed for the 01%402nd O call, so the line from Tsuna does not need to be held from the first call to the second call. This has the advantage of reducing the processing occupation period of the additional network equipment, and eliminating the need to constantly start up terminals as in the past, which eliminates the need for wasted power consumption.
