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
