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
