Now, chief telecommunications engineer to study today
Let's do it! !
It is the story of ADSL-related problems today.
Basically, the ADSL an overview of correct and incorrect sentences
I'd like to determine the problem, and I have ADSL or ISDN
Because when he was a man in his prime, this kind of problem I'm good at
Perhaps, young people these days are like the ADSL
Maybe not familiar
(Bale is so old)
Companies also are engaged, I called a "life entitled" The
I'd have been one after joining new friends, too
New communication system was not originally interested in, so
ADSL like these I like it I do not know or
Somehow, "Speaking of internet ADSL!!" I felt
I miss the days when somehow
Well, the topic I will introduce extraneous issues aside
Seems to be persistent, ADSL person is when he was Mori Tamotsu
I'm in is not particularly difficult problem?
But from that point of view even if your site s that the age
The second sentence is 4 DSLAM or not I'm not the contacts?
In the home or office to the splitter and bridge taps
There will also be set up, if you are interested to communicate
I'll get over your eye and the transmission rate, DSLAM or the
I'm so Ikimasen
By the way, DSLAM is a Digital Subscriber Line Access Multiplexer
In short, the literal translation device "digital subscriber line access multiplexer" is.
Well, please think of the huge backbone concentrators.
... It's a problem, "training" is
As they wrote the description, and availability of sub-channels which
The central office ADSL DSLAM side, there is a user communicates with a modem and
So I decide, "or any sub-channels are available?" In addition to
There will be determined in consultation as well as speed here.
Users of ADSL modem and DSLAM central office consultations between the
We are determined considering the attenuation of the signal and noise, on the path
I'd like.

Problem of PDS technology of timing of OLT or output control
The problem of ..shine.. [akusesunettowa-ku] of the PDS technology etc. is not only specialized skills (exchange) taken up, and firmly a place because the technology as the problem of the transmission exchange equipment and the plant management that happens frequently as the main in this blog to be suppressed.
PDS uses a passive multidrop equipment by abbreviating Passive Double Star and is a diverging technology in this blog as for the optical access though thought the introduction in the past two or more times.
The imagination adheres for a moment even if said, "It is passive" in short, it is a splitter though might be painful.
It was "OLT" becoming the point in today's question.
OLT is abbreviation of Optical Line Terminal and a terminating set of an optical line as shown in the name.
ONU is opposite OLT ..that.. and becomes a terminating set on bureau [**] side on the user side though thinks the desire of [mazu] ONU as for the terminating set of light and the floatage by the terminating set set up.
Note it though it wrote even at the beginning because the problem related to the optical access around here is a problem of frequent occurrence in each subject.

It is a Exchange today.
Hello.
Does chief telecommunications engineer's examination grind make progress?
We will deliver the twist for a moment today because the day before yesterday yesterday and an easy problem continued ･･･.
There is ..difficulty of the problem of this hand.." even if it is said well it is difficult and, then, when it is easy to work because it is a problem of the processor even if not ..switchboard.. familiar if the problem is read, today's material is thought [kochira] ↓↓.
- Software of digital switchboard for telephone
The software of a digital switchboard for the telephone aims at the functional partition, hierarchizing of software, and making of the interface between programs logical to facilitate the function expansion and the operation and maintenance, and is structurized.
These sentences are correct.
The space switch of a digital switchboard for the telephone is used to exchange slots of the time of the same time position between highways.
Two or more processors are prepared, the method to execute the exchange processing as the whole is called a multiprocessor control method by allotting of the function or allotting the load between these, and the method of functionally allotting similar processing with two or more processors is called a load-balancing control method.
These sentences are correct.
- The function and the load are distributed with two or more multiprocessor control method = processor and the exchange processing is executed as a whole.
- Similar processing is allotted with two or more processors load-balancing control method = functionally.
Two or more processors are prepared, the method to execute the exchange processing as the whole is called a multiprocessor control method by allotting of the function or allotting the load between these, and the method of functionally allotting similar processing with two or more processors is called a load-balancing control method.
These sentences are wrong.
- Call processing program..telephone..relay..line..selection..connection..cut..liberate..exchange..connection..operation..control..program..call..dial..figure..receive..call..talk over the telephone..stable footing..provide. The call processing program has achieved the exchange connection operation by observing, analyzing the processing demand in these states, and doing processing necessary for the following state transition.
- Program at input process: Program that scans state of local loops and relay line observing
- An internal processing program: It is composed of the program etc. that translate the program dial figure to which the connection status is decided based on the processing demand detected by the input process program.
- The output processing program: The mistake of left sentences is mis-) output processing program mis-) internal processing program →(positive) output processing program ((→(positive) internal processing program of two points because it says *･･･ composed of the program etc. that detect the program, the call out that drives a telephone call road system device etc. , the response, the local loops such as cutting or the change in the relay line.
The space switch of a digital switchboard for the telephone is used to exchange slots of the time of the same time position between highways.
These sentences are correct.
- - space switch that does the exchange connection between highways in each time slot while space switch = multiplexed exchanges the time
･･･Woops! "Space switch" was set when thinking only the problem of the processor and the program.
It is set questions too much, and does not the installation technician's examination be actual what excerpted from a past considerably old problem and have the necessity remembered too much desperately by today's material recently by "Time switch" of "Space switch" it seem not to be either?However, why don't you look over once because the technical intelligence for the licensed engineer is easily obtained by Web when googling by the key word such as "Space switch" because carelessness is a taboo?Then, around here today
