Blue Boxing Essays - Phreaking, Blue Box, Signaling,

Blue Boxing To quote Karl Marx, blue boxing has always been the most noble form of phreaking. As opposed to such things as using an MCI code to make a free fone call, which is merely mindless pseudo-phreaking, blue boxing is actual interaction with the Bell System toll network. It is likewise advisable to be more cautious when blue boxing, but the careful phreak will not be caught, regardless of what type of switching system he is under. In this part, I will explain how and why blue boxing works, as well as where. In later parts, I will give more practical information for blue boxing and routing information. To begin with, blue boxing is simply communicating with trunks. Trunks must not be confused with subscriber lines (or "customer loops") which are standard telefone lines. Trunks are those lines that connect central offices. Now, when trunks are not in use (i.e., idle or "on-hook" state) they have 2600Hz applied to them. If they are two-way trunks, there is 2600Hz in both directions. When a t runk IS in use (busy or "off-hook" state), the 2600Hz is removed from the side that is off-hook. The 2600Hz is therefore known as a supervisory signal, because it indicates the status of a trunk; on hook (tone) or off-hook (no tone). Note also that 2600Hz denoted SF (single frequency) signalling and is "in-band." This is very important. "In-band" means that is within the band of frequencies that may be transmitted over normal telefone lines. Other SF signals, such as 3700Hz are used also. However, they cannot be carried over the telefone network normally (they are "out-of-band" and are therefore not able to be taken advantage of as 2600Hz is. Back to trunks. Let's take a hypothetical phone call. You pick up your fone and dial 1+806-258-1234 (your good friend in Amarillo, Texas). For ease, we'll assume that you are on #5 Crossbar switching and not in the 806 area. Your central office (CO) would recognize that 806 is a foreign NPA, so it would route the call to the toll centre that se rves you. [For the sake of accuracy here, and for the more experienced readers, note that the CO in question is a class 5 with LAMA that uses out-of-band SF supervisory signalling]. Depending on where you are in the country, the call would leave your toll centre (on more trunks) to another toll centre, or office of higher "rank". Then it would be routed to central office 806-258 eventually and the call would be completed. IllustrationA---CO1-------TC1------TC2----CO2----BA.... youCO1=your central officeTC1.. your toll office.TC2.. toll office in Amarillo.CO2.. 806-258 central office.B.... your friend (806-258-1234)In this situation it would be realistic to say that CO2 uses SFin-band (2600Hz) signalling, while all the others use out-of-band signalling (3700Hz). If you don't understand this, don't worry. I am pointing this out merely for the sake of accuracy. The point is that while you are connected to 806-258-1234, all those trunks from YOUR central office (CO1) to the 806-25 8 central office (CO2) do *NOT* have 2600Hz on them, indicating to the Bell equipment that a call is in progress and the trunks are in use. Now let's say you're tired of talking to your friend in Amarillo, so you send a 2600Hz down the line. This tone travels down the line to your friend's central office (CO2) where it is detected. However, that CO thinks that the 2600Hz is originating from Bell equipment, indicating to it that you've hung up, and thus the trunks are once again idle (with 2600Hz present on them). But actually, you have not hung up, you have fooled the equipment atyour friend's CO into thinking you have. Thus,it disconnects him and resets the equipment to prepare for the next call. All this happens very quickly (300-800ms for step-by-step equipment and 150-400ms for other equipment). When you stop sending 2600Hz (after about a second), the equipment thinks that another call is coming towards --> on hook, no tone -->off hook. Now that you've stopped sending 2600Hz, several things happen:1) A trunk is seized.2) A "wink" is sent to the CALLING end from the CALLED end indicating thatthe CALLED end (trunk) is not ready to receive digits yet.3) A

The Divine Comedy. The World Structure and The Role of Virgil Essay

The Divine Comedy. The World Structure and The Role of Virgil - Essay Example Thus, there are at least 3 dimensions of Dante’s relationship with Ancient Greek and Roman culture: the poetical one, that is, the influence of the language and symbolism of the previous ages; the difference in world order in Dante’s and classic thinkers’ visions; and the most specific one, Dante’s relationship with Virgil as outlined in the Divine Comedy. This essay addresses all 3 of them. Poetical Aspect Many Dante scholars agree that the most important cultural trait of Classical poetry in the Divine Comedy is its style, that is, its verse, rhetorical topoi, strictness of composition, and the characteristics of genre (Curtius 353-358). Virgil, as well as other figures of ancient writers/rhapsodes such as Lucan and Homer, was the one of the â€Å"regulated poets† whose writing had an imprint of elaborate poetical systems (Curtius 354). Dante wanted his verse and his vision of afterlife to be systematic and logical. Dante’s structured of In ferno is even more elaborate than Virgil’s: in the Aeneid (VI), Aeneus travels through only three sectors of Hell, not shaped as circles and surrounded by different basins rather than parts of one system (Virgil). Still, the overall structure is the same: it is a descriptive journey with a powerful guide (Sybil in Aeneus’s case) beginning in the dark wood and ending on the light mountain top: â€Å"And takes a rising ground, from thence to see / The long procession of his progeny† (Aeneid VI.1024). As for merely linguistic influences, Curtius finds numerous Latinisms in the Divine Comedy , such as his use of the river (‘Fuime’) image used to demonstrate the eloquence of Dante’s speech as related to Virgil’s (Curtius 356). Most of these Latinisms are Medieval, not related to Renaissance poetics (Curtius 354). They indicate that Dante perceived Virgil’s worldview mainly through medieval lens. Thus, his ideas of human nature and th e structure of the world are different from Virgil’s and much closer to Christianity. The World Structure The meaning of Hell is strikingly different in the Divine Comedy and the Classic culture. Dante’s Hell and Purgatory are designed for sinners, being something like a disciplinary place for corrupted souls; thus, it has a strict hierarchy, and every punishment is logically connected with the crime, like the Diviners in Canto XX who are forced to walk with their heads turned back. The punishments are arranged according to the severity of crime, descending into the depth and ending with the frozen circle, like in other medieval literary descriptions of Hell (Turner 87). As the main function of Hell is punishment, the characters are described vividly, in the flesh, and usually with some moral assessment: Those spirits, faint and naked, color chang'd, And gnash'd their teeth, soon as the cruel words They heard.   God and their parents they blasphem'd, The human kind, the place, the time, and seed That did engender them and give them birth (Divine Comedy III.94-98) This is the description of the souls (disembodied!) about to be transported by Charon. In Virgil’s version, it is Charon who provokes disgust; the souls of the dead are described in a neutral if not compassionate way: An airy crowd came rushing where he stood, Which fill'd the margin of the fatal flood: Husbands and wives, boys and unmarried maids, And mighty heroes' more majestic shades, And youths, intomb'd before their fathers' eyes, With hollow groans, and shrieks, and feeble cries (Aeneid VI.422-427). Virgil’s vision of the afterlife, like that of many other Ancient Greeks and Romans, is morally neutral: it’s a fate, an important category of Ancient worldview. Like Ovid, Virgil believed that death is a

The lesson of the moth

The lesson of the moth â€Å"The Lesson Of The Moth† The Life That Worth Living For. In the poem â€Å"The Lesson of The Moth†, Don Marquis tells a story of a moth, an insect that have a strange habit of being attracted to the bright light. The story is being told by a fictional cockroach named Archy who is reincarnated author. The cockroach finds the moth trying to break into a light bulb to get the light inside; when he asks why he is doing this, the moth gives an incredibly profound statement: â€Å"It is better to be a part of beauty for one instant and then cease to exist than to exist forever and never be a part of beauty.† (Marquis 188). To me, that is almost what life is about. If we do not have a real reason to live, then it all seems rather pointless. One of the major symbols in the poem is the flame in which the moth is willing to die for. It implies that there are things that certain people are willing to do even if it may cost them their lives. The cockroach in the poem represents all the people who live their lives very carefully to ensure a long one. The moth symbolizes all the people who dont. Both the views of the cockroach and the moth are trying to accomplish the same thing: a better life. The cockroach wishes to live his life with half of the happiness but twice as long, while the moth, on the opposite, would rather live its life to the fullest even if it means to be cut short. When we first read this poem, we may walk away and think that the poet is pretty strange, or doesnt make any sense at all. But after we let it sink and really start to think about what its saying, it really makes much more sense. For me, after it sorted itself out in my head, it made me start thinking about a lot of things. One of the biggest was: â€Å"Why are we here? And what are we doing?† This poem also made me somewhat sad, even though there is nothing I could do about it. It made me want to have a purpose in life. I wanted to have something that I would be so devoted to that I would even be willing to give my life to. It also made me think that sometimes we just have to let go of ourselves and do whatever we want, regardless of the consequences. â€Å"But at times we get tired of using it we get bored with the routine† (Marquis 188). The author used pathos to create an emotional appeal that the â€Å"routine† of normal life is non-excite and it makes we ge t bored of repeating it. Without change, life becomes dull and monotonous. Cant we enjoy the croaking of the frog? For enjoyment, there must be variety .We enjoy the sky because it exhibits a variety of color in different tones. Whether it is taste, color, sound or smell, we want variety. Mans genius consists of his adding to the variety. But for this ever-growing variety, life would become so unbearable and the earth would become a prison. â€Å"It is better to be happy for a moment and be burned up with beauty than to live a long time and be bored all the while† (Marquis 188). In this quote, the author uses the logo to argue that its better to live a high-status life for a while rather than staying our head low for the rest of our life. Personally, I feel that that was the best expression of the word that anyone could have ever thought of; life is misery, and any individual who refuses to grow will get swallow up by life. If we have one opportunity, to see everything we ever wanted in one moment, why shouldnt we capture it? Indeed, danger may come hand-in-hand with opportunity, especially in a crisis. Danger is posed greatly if we fail to understand a situation, and when we act in ignorance to our awareness of it. It is out to hurt, to destroy and to disrupt a persons confidence and life. This will always be somewhat scary, but to live one life to its fullest we always have to take some risks. This is where self-confident is so important. If having a successful life was without risk, then everyone would have successful lives. However, not everything in a crisis is as adverse as it appears to be, despite the great danger posed in the situation, opportunities are often extended. As one saying goes, When one door closes, another one opens†; anyone who realizes that these opportunities when taken may be the solution of the crisis problem, they will onto the road of gleaming success. â€Å"But at the same time I wish there was something I wanted as badly as he wanted to fry himself† (Marquis 188); we do not only have to be smart and mature enough in the thinking of tackling the opportunity, we also has to possess a great deal of determination, fortitude and will power in order for success to reign in the final showdown. â€Å"I do not agree with him myself, I would rather have half the happiness and twice the longevity† (Marquis 188). We could see clearly the ethos in this quote: the author, being a coc kroach, doesnt agree with the idea of shining for a while then be burned up, and he choose the longevity over the happiness. I dont agree with author, you know why? Too often many of us go through our lives on autopilot, without even knowing it. You wake up in the morning, and then do the same old rituals. You go to the office or to school. You meet the same people, do the same job, and travel the same road. Next day, same story. We just let each day pass like the one before it. And when we reach old age, we might look back on life with â€Å"I should haves† and regrets. â€Å"The Lesson of the Moth† explains not only why moths always want to â€Å"immolate† themselves on lights, but also reveals a philosophy on life in a humorous way. The moths philosophy ironically made sense, because to live without ever experiencing something beautiful is truly torture. The extreme consequences of death with beauty or â€Å"longevity† without beauty are hard to decide between. The moth also explains how human beings used to be â€Å"come easy, go easy† but have become too civilized and stuck-up to enjoy themselves thoroughly. The moth says, â€Å"our attitude towards life is come easy, go easy, we are like human beings used to be before they became too civilized to enjoy themselves† (Marquis 188), the moth is right for the most part about humans being too civilized, but there are the few, the proud, the ones who dare people to drop all seriousness and go out and have fun. The people with the most money should be having the most fun, but they seem to just be too civilized to have a good time. The moth has a real good spin on a serious issue and yet makes the reader laugh while reading it. â€Å"The Lesson of the Moth† is a well-constructed story with excellent ideas that is vividly realistic. The narrative moves at a pace to engage and captivate the reader without making the story just a rush to get to the last line. The writing is thoughtful to makes sure that the reader will savor and think about the events presented. This poet is an excellent exploration of a philosophy on life that is well worth thinking about.

Don Juan Ponce De Leon :: essays research papers

Spanish 10th essay Ponce De Leon Don Juan Ponce de Leon "To bad he had to kick the bucket!" 	Don Juan Ponce de Leon was a Spanish conqueror and explorer. He was born around 1460 in San Tervas de Campos, Spain. Ponce de Leon lived during an age of great discovery and excitement. Ponce de Leon is well known, claiming and naming what is now Florida, the discovery of Puerto Rico, and his never-ending search for the old time classic, the Fountain of Youth! On November 19, 1493 Ponce de Leon was one of the first Europeans to see the small island of Borinquen, the Indian name for Puerto Rico. Ponce de Leon sailed to Puerto Rico in 1506 with two hundred men to the island and found out that it had rich gold deposits. He enslaved the natives, and forced them to mine gold for him. Ponce de Leon left Puerto Rico and returned again in 1508 this time he brought with him only fifty men. On this voyage his ship went through a terrible storm that caused him to run onto the rocks on two occasions. The crew was forced to throw over much of their supplies in order to keep the ship from sinking. After Ponce de Leon finally arrived in Puerto Rico he became the governor of the island. This caused him to become very wealthy, and the most powerful man on the island, who only received orders from the kind himself! In 1511 King Ferdinand ordered Ponce de Leon replaced as governor by Diego Columbus. Life for Ponce de Leon would have been difficult if he stayed in Puerto Rico since much of his power over the island was taken when his rank was taken away. It was at this time that Ponce de Leon began his search for the Fountain of Youth. Many historians feel it was not only to discover the LENGENDARY waters, but also for the gold and silver that was supposed to be at the sight of the fountain. Ponce de Leon explored many regional islands in his search for the Fountain of Youth, including the Bahamas and Bimini. It was during Ponce de Leon's search for the Fountain of Youth that he came to a land that he eventually named, La Florida or "land of flowers". He made two visits to this new land. On his first visit the native inhabitants were friendly to Ponce de Leon and his men.
