Hello.
Does chief telecommunications engineer's examination grind make progress?
We will deliver the twist for a moment today because the day before yesterday yesterday and an easy problem continued ･･･.
There is ..difficulty of the problem of this hand.." even if it is said well it is difficult and, then, when it is easy to work because it is a problem of the processor even if not ..switchboard.. familiar if the problem is read, today's material is thought [kochira] ↓↓.
- Software of digital switchboard for telephone
The software of a digital switchboard for the telephone aims at the functional partition, hierarchizing of software, and making of the interface between programs logical to facilitate the function expansion and the operation and maintenance, and is structurized.
These sentences are correct.
The space switch of a digital switchboard for the telephone is used to exchange slots of the time of the same time position between highways.
Two or more processors are prepared, the method to execute the exchange processing as the whole is called a multiprocessor control method by allotting of the function or allotting the load between these, and the method of functionally allotting similar processing with two or more processors is called a load-balancing control method.
These sentences are correct.
- The function and the load are distributed with two or more multiprocessor control method = processor and the exchange processing is executed as a whole.
- Similar processing is allotted with two or more processors load-balancing control method = functionally.
Two or more processors are prepared, the method to execute the exchange processing as the whole is called a multiprocessor control method by allotting of the function or allotting the load between these, and the method of functionally allotting similar processing with two or more processors is called a load-balancing control method.
These sentences are wrong.
- Call processing program..telephone..relay..line..selection..connection..cut..liberate..exchange..connection..operation..control..program..call..dial..figure..receive..call..talk over the telephone..stable footing..provide. The call processing program has achieved the exchange connection operation by observing, analyzing the processing demand in these states, and doing processing necessary for the following state transition.
- Program at input process: Program that scans state of local loops and relay line observing
- An internal processing program: It is composed of the program etc. that translate the program dial figure to which the connection status is decided based on the processing demand detected by the input process program.
- The output processing program: The mistake of left sentences is mis-) output processing program mis-) internal processing program →(positive) output processing program ((→(positive) internal processing program of two points because it says *･･･ composed of the program etc. that detect the program, the call out that drives a telephone call road system device etc. , the response, the local loops such as cutting or the change in the relay line.
The space switch of a digital switchboard for the telephone is used to exchange slots of the time of the same time position between highways.
These sentences are correct.
- - space switch that does the exchange connection between highways in each time slot while space switch = multiplexed exchanges the time
･･･Woops! "Space switch" was set when thinking only the problem of the processor and the program.
It is set questions too much, and does not the installation technician's examination be actual what excerpted from a past considerably old problem and have the necessity remembered too much desperately by today's material recently by "Time switch" of "Space switch" it seem not to be either?However, why don't you look over once because the technical intelligence for the licensed engineer is easily obtained by Web when googling by the key word such as "Space switch" because carelessness is a taboo?Then, around here today

Even if a net synchronous method is said
Well, there is considerably a person who googles to analyze the person whom this blog inspected by the key word 【 telecommunication chief engineer reference book 】 though 20 days have passed since the study of the chief telecommunications engineer today, and this blog were established. Is all "It is necessary to study on earth with what" evidences to worry?This..blog..past..several times..write..think..this..qualification..reference book..exist..enough..test range..narrow..past..ask..get tired..the..inside..doubt..matter..good at..field..enumerate..correspond..technical book..buy..think.Then, today's material is [kochira] ↓.
- Net synchronous method in digital data exchange network
The variable frequency oscillator is prepared in each bureau in the net, and the method to control the oscillatory frequency of the bureau based on the phase lag of the clock of another bureau and the clock of the bureau is called mutual synchronous methods.
These sentences are correct.
- The variable frequency oscillator is prepared in each bureau in the net mutual synchronization =, and the oscillatory frequency of the bureau is controlled based on the phase lag of the clock of another bureau and the clock of the bureau.
The method to match the frequency of the general situation in the net by preparing one main oscillator in the master station (master bureau), and distributing the clock of the master station is called a subordination synchronous method.
These sentences are correct.
- Method to match frequency of general situation in net by preparing one main oscillator in slave synchronization = master station, and distributing clock of master station
A subordination synchronous method is divided into a strong connection type and a weak connection type depending on the action method of the master station when the disturbance and the breakdown occur in the clock distribution.
These sentences are wrong.
- A subordination synchronous method is divided into a strong connection type and a weak connection type depending on the action method of the tributary station in preparation for time when the disturbance and the breakdown occurred in the clock distribution.
- The breakdown influences a subordination synchronous method the disturbance of the transmission line.
- Make noise because it disturbance = is confused. Moreover, disturb the peace and order. Disturbance.
- Then, do not undertake all influences when the disturbance and the breakdown occur because everyone follows the master station.
The control over between bureaux is unnecessary though the oscillator with high accuracy like the cesium oscillator is demanded as for independence and synchronous a method.
These sentences are correct.
- Naturally, "Control over between bureaux" might be unnecessary because it becomes independent.
Today's material was a problem of the synchro system for the digital data exchange network. The net synchronization might be able technological used by the multiplexer etc. to say nothing of the switchboard to correspond considerably even if there is no knowledge of the district if the meaning of the word is often considered though comes out "Mutual", "Subordination", "Independence" or various methods. Then, around here today

It exchanges it today.
Does the chief telecommunications engineer's study make progress?Excellent study is necessary for passing of the chief telecommunications engineer of the transmission exchange and it just prays that be able it to sleep, and to become your post even a little this blog sincerely. Then, today's material is [kochira] ↓.
- Call processing program of digital switchboard for telephone
Call processing program is divided roughly into internal processing and the output processing at the input process. As for these processing, the operation order is controlled by the maintenance operation program, and high processing of the emergency degree interrupts low processing and is executed.
These sentences are wrong.
- As for these processing, the operation order is controlled by a central controller, and high processing of the emergency degree interrupts low processing and is executed.
- ..floatage.. ?As for "Maintenance operation program" [n] and in sentences, is the part good for "Central processing unit" if it mends?
- A central controller moves at the base level when all work at the clock level ends and is processing work. The result is brought together on the way of work when the constant period passes before work at the base level ends and the work that interrupts at the base level at the next cycle is drawn out after it interrupts, and it works at the clock level and it restarts.
- Is there such sentences, too and "Maintenance operation program" →"Central processing unit. " in sentences perhaps?｡｡
It is caught as input information, and internal processing begins if the state of the clock is observed, and there is a change at the input process.
These sentences are correct.
- It is assumed to be input information if the state of the local loops or the line like the call out, the response, cutting, and the dial pulse, etc. is observed, and there is a change and catching the internal processing begins at the input process.
- "State of the clock" is not observed and "State of the subscriber or the line" is observed.
- ｡｡｡Are not you the no use of observing the clock it?
Internal processing analyzes input information, does necessary processing, and the output processing drives a telephone call road system device based on the result. A series of processing that selects the trunk and the route in internal processing is called a token.
These sentences are wrong.
- A series of work to select the trunk and the route in internal processing is called routing. It is correct in the first halfs of sentences.
- It is not a token and routing.
The transition condition between these states is described and the one having provided for piece processing function is called a state transition chart though it can be thought that the process from "Start of call" of one "Call" to "End of call" is the transition between two or more states.
These sentences are correct.
- The one that the transition condition between state transition chart = states is described and regulations of piece processing function
- The process from "Start of Call" of one "Call" to "End of Call" is a transition between two or more steady states.
It is possible to provide for "Call processing program" by the state transition chart to have recorded the transition condition between these states.
Well, often note successfully caught to hanging if there are a lot of problems sleeping around here excellent nasty the problem of the call processing program this time and the flow of the term and processing is not remembered neatly. Then, around here today

It is a chief telecommunications engineer today.
The chief telecommunications engineer's of today study also puts "Exchange" to the subject. It publishes by two titles though it does because there is no time for a moment today at a smart trot. Then, the materials of eyes are [kochira] ↓ of one.
- Composition of switch of time of digital switchboard for telephone
The time switch is a device used for the speech path, and it is composed of the telephone call memory, the control memory, and the counter circuit.
These sentences are correct.
- It is composed of the telephone call memory, the control memory, and the time switch = circuit of the counter.
The telephone call memory is a memory that stores tonal information etc. that correspond to the multiplicity of the highway encoded digitally.
These sentences are correct.
- Memory that stores tonal information etc. that correspond to multiplicity of telephone call memory = highway encoded digitally
The control memory is a specified memory.
These sentences are correct.
- It is a specified memory. read
The counter circuit is a circuit to read sequentially or to write tonal information etc. encoded digitally in the control memory.
These sentences are wrong.
- The counter circuit is a circuit to read sequentially or to write tonal information etc. encoded digitally in the telephone call memory.
- It is not "Control memory", and "Telephone call memory" answers correctly.
Well, how?It remembers because it colors in will the point of each circuit the part of the deficit of a right cell. Then, today's the second material is [kochira] ↓.
- Multiprocessor control method of digital switchboard for telephone
In a function distributed control method, two or more processors are processing it respectively. To execute one exchange processing, the sending and receiving of information between these processors is necessary, and the sending and receiving of this concession is called an inter-processor communication.
These sentences are correct.
- Sending and receiving of information exchanged between processors to execute inter-processor communication = one exchange processing
In the inter-processor communication, it is possible to meet until it becomes possible to communicate the reception side processor because the state of each processor function is uniformly managed by the meeting control operation, and it accumulates communication information from the transmission side processor in the buffer memory once.
These sentences are correct.
- It meets until it becomes possible to communicate the reception side processor because the state of meeting function = each processor function is uniformly managed, and it accumulates communication information from the transmission side processor in the buffer memory once.
In the inter-processor communication, the bus can be prevented from competing according to the priority level provided beforehand when use rights of the bus between processors are uniformly managed by the rival control function of the bus, and there is a use demand of the bus.
These sentences are correct.
- The bus is prevented from competing according to the priority level provided beforehand when use rights of the bus between rival control function = processors of the bus are uniformly managed, and there is a use demand of the bus.
Yes, a problem here was a problem of the processor control method. Is there what worries so much if do not limit to the switchboard, and well versed in the equipment that uses "Processor"?I think that such a problem is brought up even if a technical engineer is studied. Then, it is necessary to work hard study of you and the chief telecommunications engineers. Around here today

Control scheme in digital switchboard for telephone
Today's chief telecommunications engineer's material is "Switchboard. "Isn't the part of 【 exchange 】 as still important as that of taking side of "Transmission exchange" with the chief transmission and switching engineer?It thinks. "To begin with, what is the switchboard?" do not roughly understand even by the person even as for the person not involved in the switchboard though the problem of hitting the category of "Control scheme" in the problem of the exchange today if sentences are calmly read in case of the problem today?Then, today's material seen once is [kochira] ↓↓.
- Control scheme in digital switchboard for telephone
The control scheme to which all the exchange processing is done with one processor is called a centralized control method, and the control scheme to which the exchange processing is done with two or more processors according to each function or the load is called a distributed control method.
These sentences are correct.
- Centralized control method = Control scheme to which all exchange processing is done with one processor
- Control scheme to which exchange processing is done with two or more processors according to each function or distributed control method = load
In the centralized control method, the system processing performance depends on the ability of the processor. Moreover, two or more processors make troubleshooting/restart process complex from the method to distribute processing according to a different function.
These sentences are wrong.
- Certainly, troubleshooting/restart process will become simple because it is good when only a single processor is seen though might depend on the ability of the processor for the processing performance in the centralized control method.
A function distributed control method to allot the identical function with two or more processors can do large-scale processing by comparatively using two or more processors with small processing performance.
These sentences are wrong.
- "The identical function is allotted with two or more processors" might not be a function distributed control method and be a load-balancing control method.
How?Is Japanese calmly read even if it doesn't know "The technology" somehow and can it not answer correctly if it solves it?However, it is necessary to catch calmly often reading the problem because the expression of the problem is nasty. Then, let's see the problem of the switch system of another one today. This material is [kochira] ↓↓.
The time switch is each time slot and a switch that does the exchange connection between highways while arrange the timesharing gate between the insertion highway and ..putting out.. highway, high-speed this timesharing gate, and multiplexed by opening and shutting.
These sentences are wrong.
- ｢It is a switch that replaces information by using the gate element that operates at high speed between high ways, and it is called the high way switch. The space switch is composed of the control memory that controls the opening and shutting of the gate of a lattice gate circuit and each time slot. ｣
- "Space switch" answers "Time switch" of sentences of the problem correctly.
If the multiplicity of the highway that goes in and out is assumed to be n, the time switch functions as a lattice of a complete group where internal congestion doesn't exist, and can be shown with the space division type switch of n×n.
These sentences are correct.
- I will memorize these sentences round ･･･.
The space switch is a replaced switch in an arbitrary time slot on the highway. put out the slot of time on the insertion highway
These sentences are wrong.
- Because it is "Time slot" to replace the time slot, the time switch though it neatly examines and it doesn't exist.
The control memory of the space switch of each insertion highway has been installed.
These sentences are wrong.
- The space switch is a switch that replaces information by using the gate element that operates at high speed between high ways, and it is called the high way switch. The space switch is composed of the control memory that controls the opening and shutting of the gate of a lattice gate circuit and each time slot.
- I think that it is a mistake of "Gate circuit and each time slot .."Each insertion highway" of the problem sentence.." ..holding perhaps...
Well. Then, it was a problem of "Time switch" and "Space switch" though it was this problem. I think that you should see the reference book of an installation technician who is older to count on chief telecommunications engineer's reference book and problem collection perhaps when the problem around here will be studied in detail and study though a big thing cannot be said because I am not considerably good at the problem of this "Time switch" and "Space switch". Installation technician's reference book is considerably kind and, anyway, sleep ･･･ Then, around here today

- Digital switchboard for telephone
A digital switchboard for the telephone should maintain high reliability for a long time, and provide steady service continuously.
- Well, the switchboard is an expensive shopping and it doesn't become work if use for a long term, and not dependable.
In a digital switchboard for the telephone, processing (breakdown processing) that gives the breakdown measures to hardware and each software, detects the state promptly in abnormal circumstances, and does again normally has been achieved.
- The breakdown measures are given to each hardware software.
As for the breakdown processing, it is demanded that it is necessary to deal with all the system malfunctions effectively, it is necessary to process 【 in short course 】 extremely, and the incompleteness of the breakdown processing be concise, certain processing [houhou] because it becomes a fatal defect of the system.
- It is necessary to deal with the point and all the system malfunctions of the breakdown processing effectively. - It is necessary to process 【 in short course 】 extremely. - The incompleteness of the breakdown processing becomes a fatal defect of the system. - It is demanded that it be concise, certain processing [houhou].
Abnormality of the common control unit such as processors installs an abnormal detecting function in hardware as one of the failure detection techniques with hardware because the influence that it has on the system is large, and there is a method of starting the breakdown processing program stored in a fixed house number with 【 interrupt 】 circuit when abnormally detecting it.
- When * abnormality with a large influence that it has on the system is detected, abnormality of the common control unit such as processors starts the breakdown processing program stored in a fixed house number with 【 interrupt 】 circuit.
Moreover, there is a method of observing whether to fall in check on 【It is periodic 】, and 【 infinite loop 】(Processing circulates to the same program, and the control is not transferred to another program) the control of the clock level and the base level as one of the fault detections with software.

Topic of call processing of PBX.
Yes, I think that the material of the study of the chief telecommunications engineer goes by the exchange today. Which program is which problem of judging whether to call and to do [no] processing though today's material is a call processing program of the switchboard. Then, today's material is [kochira] ↓↓.
- Outline of call processing program of digital switchboard for telephone
The call processing program calls and is [niha] and becomes empty, is in the call while talking over the telephone while receiving the dial figure this steady state, and has achieved the exchange connection operation by observing, analyzing the processing demand in these states, and doing processing necessary for the following state transition.
These sentences are correct.
- It ..calling.. ..[niha].. becomes empty, and this steady state exists while talking over the telephone while receiving the dial figure the call inside.
- The exchange connection operation is achieved by observing, analyzing the processing demand, and doing processing necessary for the following state transition.
An internal processing program is composed of the program etc. that detect the call out, the response, the local loops such as cutting or the change in the relay line.
These sentences are wrong.
- An internal processing program: It is composed of the program etc. that translate the program dial figure to which the connection status is decided based on the processing demand detected by the input process program.
- ･･･ Internal processing is opposite to the output processing.
The output processing program possesses the function to decide the connection status based on the processing demand detected by the input process program, and is composed of the program etc. that translate the dial figure.
These sentences are wrong.
- The output processing program: It is composed of the program etc. that detect the program, the call out that drives a telephone call road system device etc. , the response, the local loops such as cutting or the change in the relay line.
- ･･･ Internal processing is opposite to the output processing.
Well, how?In short, the explanation of "Internal processing program" in the problem sentences and "Output processing program" was only opposite to sentences of the mistake apart from correct sentences. Roughly, the division really composed of the program of "Dial figure translation" like the input process though it says is not in the output processing. ｡｡Then, around here today.

BORSCHT was heard after a long time.
I think that today's chief telecommunications engineer's examination grind goes by the material of the exchange. Well, it somewhat thinks the step improvement after installation technician's qualification is acquired to chief telecommunications engineer's qualification to be a problem of being easy to work though there is a material [ttetottsukiyasui] image of "Exchange" because it is related to the business that I am involved in the switchboard. Then, today's material is [kochira] ↓↓.
- About the BORSCHT function of a digital switchboard for the telephone in the subscriber circuit
“B" of the BORSCHT function is abbreviation of Battery feed, and the function to supply the direct current needed when the dial pulse of the supply of the telephone call current is received another.
These sentences are correct.
- B's of BORSCHT is none.
- B supplies the current.
“S" of the BORSCHT function is abbreviation of Signaling, and the function to send the dial-tone, the ringing tone, and the engaged tone, etc.
These sentences are wrong.
- The function that the call out and the response, etc. from the subscriber can be observed by observing the current that flows to the L1 line and the L2 line with the direct current watch circuit is called S(loop watch) function in the subscriber circuit of S(loop watch) digital telephone switchboard. For instance, it is judged that the telephone is an off hook more than the threshold with the harmony of the current of the L1 line and the L2 line it.
- S thinks that no Signaling and Supervision. ｡｡
As for “C" of the BORSCHT function, is it a modulator and in the abbreviation of Coder, analog that consists of the recovery machine?It is a function that converts it digitally.
These sentences are wrong.
- The function to convert the analogue signal and the digital signal is called C function in the BORSCHT function in the subscriber circuit of C(analog to digital conversion) and the digital telephone switchboard.
- The function to convert the analogue signal and the digital signal is called A/D mutual conversion function. - Because "C" analogue signal/converts a digital signal with Codec, I think it is amusing in "Modulation and recovery" (The modulation is speaking the amplitude, the frequency, and the pulse).
Well, how?It is a problem of B, S, and C in that though today's material was BORSCHT of the exchange. I think the installation technician's examination to be a familiar problem in the chief telecommunications engineer's being taken an examination because BORSCHT was a requiring problem before. ･･･ Then around here today

Because of the transmission exchange telecommunication chief engineer
Well, I think that the knowledge of "Transmission" or "Exchange" is still important because of the transmission exchange telecommunication chief engineer though the chief telecommunications engineer is studied as usual today. The material of the switchboard system is published today because of saying. Then, today's material is ↓↓.
- Digital switchboard for telephone
In the software of a digital switchboard for the telephone, priority is set to each program to execute various processing efficiently, and the execution control form corresponding to the character is taken in real time.
- The software of a digital switchboard sets priority to the program, and takes the execution control form corresponding to the character in real time.
【 emergency 】The one to interrupt processing even if there is a program under execution, and to execute the breakdown processing, and as for the level control, information on the processing of the program that interrupts while executing it is saved in a specific memory area, and, besides, will wait for the restart of processing when 【 abnormality 】 of the system like the breakdown etc. is detected.
- Information on the processing of the program that interrupts while interrupting processing even if there is a program under execution, executing the breakdown processing, and executing it is saved in a specific memory area, and, besides, waits for the restart of processing when 【 abnormality 】 of the system like 【 emergency 】 level control = breakdown etc. is detected.
The clock level control in real time secures the character for 【 periodic 】 by starting the program in the form that controls the program that needs accurate timing.
- The character is in real time secured for 【 periodic 】 by starting the program in the form that controls the program that needs timing clock level control = accurate.
Base..level..control..in real time..character..restriction..gradual..program..control..form..service..analysis..processing..number..translation..processing..system..very..need..call processing program..maintenance..operation..related to..program..start..use.
- When it is a form that controls the program that the restriction of the character is base level control = in real time gradual, and the call processing program that doesn't need the system between very much and the program related to the maintenance operation is started, it uses it.
It asks and one [no] has been published up to now in the past how many days it, and which sentences are mistakes, and is it correct or does : by the memory point?It is "Fill-in-the-blank question" this time though publishesThe part of left 【XXX】 is actually set as making up in the past and because it is a thing, it takes care. The part that shows a loss on the right side classifies the part that I felt personal "It is important", and refer, please. Then, the following : the material that judges the corrections of sentences please up to now.
- Start of program in base level control
The program that controls the start of each program in what order it is necessary to start the program of the base level is called a driving management program.
These sentences are wrong.
- It is composed that it is an operating sushi stem (execution management) in which order that manages the schedule whether start by the program, it calls, confronts the program group that corresponds respectively in each division [sareta] [yoshori] and which timing of these [ni] ..the arbitrary occurrence.., and so as not to ruin it, a real-time character is devised.
- is division, and no "Driving management program. " perhaps. "Executive control program"
When all the processing of the program at the clock level ends, the program at the base level is started.
These sentences are correct.
- Naturally, after all the processing of the clock level ends, the processing of the base level is executed. 。。
The program at the base level is executed in the specification order by succession from the program of the clock level.
These sentences are wrong.
- Work at the clock level that it is interrupted at each constant period (The example: 8ms) and the emergency degree is high is made to intervene it though central controller (CC:Central Control) that works and controls the switchboard with software is usually working at a gradual base level of the time restriction. This is called a clock interruption. A central controller moves at the base level when all work at the clock level ends and is processing work. The result is brought together on the way of work when the constant period passes before work at the base level ends and the work that interrupts at the base level at the next cycle is drawn out after it interrupts, and it works at the clock level and it restarts.
- Program of clock level is made to interrupt by priority, and because only work at base level is restarted when everything is ended when it ends all by processing work at clock level, and "Succession from clock level" is not done separately during base level work though cannot it able not to have been so significant and to know sentences aboveIt is "The work that I was interrupting is succeeded. " if it dares to say.
Well, it is a topic of the switchboard this time. It is not a problem of worrying so much when the priority level at the clock level and the base level is neatly understood. How what is as of now though the rate of setting questions of the problem of the operating system of such a switchboard was high in old times?Because it is "Transmission exchange telecommunication chief engineer" as said even at the beginning still, I will remember as one respondent knowledge though I cannot say indescribably because the problem collection in recent years doesn't look over at all. Then, around here today.
