There is no reference book of the chief telecommunications engineer goodness ･･･.

If an almost useful reference book doesn't exist but even exists, chief telecommunications engineer's examination grind is easily useless ･･･ It is high in it. As the study method, it is a question in the past and [tteitte]. Giving it a butcher's when it asks and the word doesn't know in [no] is derived in the past is the one even of the problem of a considerably new technology that comes to be able to be answered when it depends, [ka] [samon] is digested, and it becomes accustomed to the atmosphere of the problem as the desire that the stance is the best. Well, today's material is ↓↓ *ATM.


As for synchronous transfer mode (STM), the multiplexed signal is periodically arranged. Therefore, because 【 time slot 】 is occupied by the signal when information not periodic is multiple transmitted, it is not efficient.

Because the time slot is decided at the cycle, inefficiency [nanona]. synchronous transfer mode ** STM = ..correct.. these sentences



It is said packet forwarding mode (PTM) is a method to divide information into the packet of 【 variable-length 】, and to do the protocol translation and the control of the mistake sending again in each packet, and it is unsuitable for the high-speed communication.

These sentences divide packet of ..correctness.. * forwarding mode = variable-length into the block.



To supplement these faults, information is transmitted by the cell of 【 fixed length 】 including connection destination information etc. in asynchronous transfer mode (ATM). Moreover, 【 hardware 】 can be processed because periodicity is not restricted when it is multiple because there is no frame cycle like the synchronous multiplex, many kinds of rate information can be multiplexed, and complex protocol processing is not done, and the achievement of speed-up is easy.

These sentences are correct. - It divides into the cell of ATM = fixed length (53 bytes).
