Communication engineer interview self -introduction and interview questions will go to interview communication engineers. I don't know how to introduce themselves, and want to get a better interview to introduce themselves. It's a bit anxious. What kind of question will be asked about the interview of the communication engineer?

Introduction to the interview of the communication engineer
通 通, my name is ***, the following is my self -introduction:
During college, I always aim to improve my comprehensive quality, with the comprehensive development of myself as the overall development of myself. Establish a correct outlook on life, values and world views. In order to meet the needs of social development, I carefully study various professional knowledge and give full play to my own specialties; tap my own potential, and combine the annual summer social practice opportunities, so as to gradually improve my ability to learn and analyze the problems and certain ability to analyze and deal with problems. Coordinate organizational and management capabilities.
"Learning and knowing insufficient" is the motivation for studying and work during my college. In addition to compulsory courses, I also insist on learning various professional software such as Office, Flash, FrontPage, Photoshop. After studying, I have not forgotten to participate in various sports and social activities. In terms of ideological and behaviors, I have a good style, sincere to treat people, can better handle interpersonal care, calm and stable things, and can reasonably arrange matters in life.
The interview questions for communication engineers are as follows
1. In the process of digitalization of voice signals, the quantification method is not uniformized. 2. In PCM30/32 system, the time interval of each code is 488ns. 3. In the PCM30/32 system, TS0 is used for transmitting frame synchronization signals, and TS16 is used to transmit transmits.
4, PCM30/32 systems, the repetitive frequency of re -frame is 500Hz and the cycle is 2ms.
5. The hardware of the program -controlled switch can be divided into two parts: road system and central control system. The control software of the entire switch is placed in the control system memory.
6. The zero -color scattered wavelength of the average silicon fiber is about 1310nm, and the minimum loss point is about 1550nm wavelength.
7. G.652 optical fiber is a single -mode fiber with zero -color scattered wavelength of 1310nm. 8. The basic structure of the optical cable consists of a cable core, enhanced component, and sheath.
9. The commonly used optical cable structures include layers of twisted optical cables, bundle tubular optical cables, skeleton -type optical cables and band -shaped optical cables.
10. In the topology structure of the mesh mesh, n nodes are fully connected with N (N-1)/2 transmission lines.
11. In the topology structure of the star network, N-1 transmission lines are required for N-1 node.
12. ATM technology is a combination of circuit exchange technology and group exchange technology. 13. According to the "Automatic Exchange Phone (Digital) Network Technology System" released in 1998, my country's telephone network is divided into three levels.
14. According to the new telephone network system, my country's long -distance telephone network is divided into secondary. 15. When the entire network of the telephone network is three levels, the largest number of connecting circuit segments between the two ends is 5 segments, and the at most 6 connection exchange centers are 6.
16. The first -level long -distance exchange center (DC1) is the province (autonomous region, municipality) long -distance exchange center. Long -distance terminal phone at the place where the first -level exchange center is located.
17. The first -level long -distance exchange center (DC1) is connected by the base network. 18. According to the flow of the traffic flow, the second -level long -distance exchange center (DC2) can also establish a direct circuit group with the non -owned first -level long -distance exchange center DC1.
19. DC1 of the first -level long -distance exchange center can have the functions of secondary long -distance exchange centers. 20. The selection order of the local network is: direct route, circuitous circuit, and final route.
20. The selection of the local network is: direct route, circuitous circuit, and final route.
21. In the local network, the maximum number of connecting circuits of the upper end to the end of the principle does not exceed 3 segments
22. According to CCITT's suggestion, the length of the domestic effective number does not exceed 12 bits, the international valid number length does not fail the length of the number More than 15 bits.
3. The current number method used by my country's telephone network is not equal number.
24. NO.7 signaling, the message transmission part includes three functional grades of signaling data links, signaling link functions and signaling network functions from low to high.
25. The domestic NO.7 signaling network adopts a three -level signaling network consisting of HSTP, LSTP and SP.
6. Common synchronous reference signals include 2048kbits/s and 2048kHz. 27. my country's NO.7 signaling network is a three -level network structure.
8. Among my country's NO.7 signaling network, the first -level HSTP uses A and B plane connection methods. Each HSTP mesh in the plane of A and B planes is connected to HSTP with A and B plane pairs.
9. Each LSTP must be connected to the HSTP in paired in paired in A and B planes through the signaling chain.
30, LSTP to A and B planes, the two HSTP signaling link groups work between load sharing.
In fact, it is not difficult to introduce self -introduction to the Ministry of Life. It is most important to maintain freshness. The point is to put forward your views through self -introduction to reflect your advantages of confidence, humility, stability, and hard work. The most important thing in this process is the word: stability. 1. In your attitude of life, it is best to quote a few philosophies that young people know.
2, what have you done in any way; the main content, what do you plan to do later, and put forward some practical targeted opinions.
What do you have to do in your self -introduction: Come on! Self -introduction is actually allowing others to know more about you in the first time.
1, self -confidence, atmosphere.
2, humility, qi
3, friendly
4, small humor, but you must be clever, think clearly, always let others see you very much at all times Smart, very confident! Smooth what you say! You can't be timid, that is to show yourself to others. No matter what you do, you must first sell it yourself, so that others will be optimistic about you. But throughout the process, you must have confidence in yourself. If you don't even believe yourself in yourself, who else will believe you? Come on! Confidence is the most important!
