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
