Inc. Telecommunications Improvement and Cost Cutting Effort Introduction This is the initial feasibility study for the upgrade of the S.T.C. Inc. (Small Technical Company Incorporated) network in conjunction with the office move. The purpose of the study is to evaluate the upgrade to be done on the telecommunications system recommending the most cost effective solutions on the market today. After this report a project will be started to implement the recommended solution. The deliverable for this paper will be an implement able cost effective telecommunication solution. S.T.C. Inc. will acquire the hardware necessary to support and run the new system and programming changes will be performed by outside vendors. Internet Telephony Service Providers (ITSP) may use a single infrastructure for providing both, Internet access and Internet telephony. Only data-oriented switches could be deployed for switching data as well as packetized voice. Multiplexing data and voice could also result in better bandwidth utilization than in today's over-engineered voice-or-n othing links. (www.iptel.org), 2004. The business benefits of this type of infrastructure are increased productivity, grater business flexibility and reduced operational costs. (www.cisco.com),2004 Trends in IP Telephony IP telephony is the technology for transmitting voice communications over a network using IP open standards and it uses a single network for the transmission of data, voice and video. There are currently many devices which use similar technologies to accomplish this tasks. Companies in today’s economy are looking for ways to reduce the cost of doing business and IP telephony provide this opportunity. IP telephony will continue to see tremendous activity and make incredible gains in the enterprise space. Until the service providers work their way through all that excess inventory, and are once again ready to research new technology, you can rest assured that next-generation telephony will be busy gaining traction in the enterprise market.(www.tcnet.com,2004) Cost Savings Model Analog and digital based phone systems that use a different set of communication protocols but similar cables to connect to a POP (Point Of Presence) are a very familiar site. These are present not only in home setting, but also in large industrial and office application. These applications in a very large scale are very expensive not only to maintain but also for the reoccurring cost associated with the monthly usage and fees charged to the customer by the service provider.

Raymond’s Run: POV change of Hazel Essay
Raymond’s Run is a story written by Toni Cade Bambara who describes the events that take place in the life of a skinny girl named Hazel Elizabeth Deborah Parker, a little African-American girl with a squeaky voice (which gives her the nickname â€Å"Squeaky†) that has passion to run. In this story Hazel changes her views about things a lot in this story. Such as her POV on Raymond, Gretchen and others in general/ Raymond suffers a metal disease. He’s bigger and older than Hazel, but a lot of people call him Hazel’s little brother because he needs to be looked after. â€Å"Squeaky†often takes strolls down Broadway so she can practice her breathing exercises while she keeps an eye on her brother all the time. She makes Raymond walk on the inside because he always makes fantasies so he starts thinking he’s a circus performer and that the curb is a tightrope strung high in the air. Hazel used to thing She hates a girl named Gretchen and her friends Mary Louise Williams from Baltimore because Gretchen’s a rival for the fifty-yard dash. She believes â€Å"she’s tough, not a strawberry or someone who enjoys dancing on her toes, she likes to run and this passion had made her to win many trophies, ribbons and it’s because of her velocity.†She says in this story. Every time just before she takes off in a race, she feels like she is in a dream, the kind you have when you’ve fever and feel hot and weightless. She usually dreams she flies over a sandy beach in the early morning sun, touching the leaves of the trees. She also perceives the smell of apples just like in the fields.

How the Mongols Took Over Baghdad in 1258
It took just thirteen days for the Ilkhanate Mongols and their allies to bring the Golden Age of Islam crashing down. Eye-witnesses reported that the mighty Tigris River ran black with ink from the precious books and documents destroyed along with the Grand Library of Baghdad, or Bayt al-Hikmah. Nobody knows for sure how many citizens of the Abbasid Empire died; estimates range from 90,000 to 200,000 up to 1,000,000. In two short weeks, the seat of learning and culture for the entire Muslim world was conquered and ruined. Baghdad had been a sleepy fishing village on the Tigris before it was promoted to the status of the capital city by the great Abbasid caliph al-Mansur in 762. His grandson, Harun al-Rashid, subsidized scientists, religious scholars, poets, and artists, who flocked to the city and made it an academic jewel of the medieval world. The scholars and writers produced countless manuscripts and books between the late 8th century and 1258. These books were written on a new technology imported from China after the Battle of Talas River, a technology called paper. Soon, most of the people of Baghdad were literate and well-read. Mongols Unite Far to the east of Baghdad, meanwhile, a young warrior called Temujin managed to unite the Mongols and took the title Genghis Khan. It would be his grandson, Hulagu, who would push the boundaries of the Mongol Empire into what is now Iraq and Syria. Hulagus primary purpose was to solidify his grip on the heartland of the Ilkhanate in Persia. He first completely annihilated the fanatical Shiite group known as the Assassins, destroying their mountain-top stronghold in Persia, and then marched south to demand that the Abbasids capitulate. The Caliph Mustasim heard rumors of the Mongols advance but was confident that the entire Muslim world would rise up to defend its ruler if need be. However, the Sunni caliph had recently insulted his Shiite subjects, and his own Shiite grand vizier, al-Alkamzi, may have even invited the Mongols to attack the poorly-led caliphate. Late in 1257, Hulagu sent a message to Mustasim demanding that he open the gates of Baghdad to the Mongols and their Christian allies from Georgia. Mustasim replied that the Mongol leader should return to where he came from. Hulagus mighty army marched on, surrounding the Abbasid capital, and slaughtering the caliphs army that sallied out to meet them. The Mongols Attack Baghdad held out for twelve more days, but it could not withstand the Mongols. Once the citys walls fell, the hordes rushed in and collected mountains of silver, gold, and jewels. Hundreds of thousands of Baghdadis died, slaughtered by Hulagus troops or their Georgian allies. Books from the Bayt al-Hikmah, or House of Wisdom, were thrown into the Tigris, supposedly, so many that a horse could have walked across the river on them. The caliphs beautiful palace of exotic woods was burned to the ground, and the caliph himself was executed. The Mongols believed that spilling royal blood could cause natural disasters like earthquakes. Just to be safe, they wrapped Mustasim in a carpet and rode their horses over him, trampling him to death. The fall of Baghdad signaled the end of the Abbasid Caliphate. It was also the high point of Mongol conquest in the Middle East. Distracted by their own dynastic politics, the Mongols made a half-hearted attempt to conquer Egypt but were defeated at the Battle of Ayn Jalut in 1280. The Mongol Empire would grow no further in the Middle East.
