...An Exploration of the investigations used to diagnose stroke Methods Used to Diagnose a stroke There are many different tests that can be carried out to help diagnose a stroke. The main way in which they are found is by using brain imaging so that they are able to pick up any visual issues. Brain imaging allows the doctors to understand whether the stroke was ischemic or hemorrhagic. It also allows them to determine how severe it was. Those who have suffered from a stroke must have a brain scan within 24hours to ensure the best diagnosis can be given to them allowing them to recover much better. Other tests are carried out to help the doctors realise the other smaller effects that the stroke has had upon the patient, these tests are smaller and easier to do but are no less important in allowing the stroke to be diagnosed. Brain Imaging (CT and MRI) CT and MRI scans are popular methods to carry out brain imaging. CT scan is rather like an X-ray which is more detailed and built up into a 3D image. An MRI scan creates an extremely detailed picture of the patient’s body. Both scans are useful in diagnosis however the particular one carried out depends upon how severe the doctors feel your stroke may have been. Both types of scans have their individual pros and cons as they are appropriate to reach different needs of the patient. Blood Tests Blood tests may be taken as these will tell us the person’s cholesterol and blood sugar levels, so that they are able to receive a wider understanding...

...Nt1330 Service Provider Types RBOCS Regional Bell Operating Companies (RBOCS) was formed in 1984 due to the breakup of AT&T based on a restructure agreement. RBOCs were organized into seven regional Bell holding companies called Ameritech, Bell Atlantic, Bell South, Nynex, Pacific Telesis, Southwestern Bell, and US West. The BOCs were given the right to provide local phone service while AT&T was allowed to retain its long-distance service. RBOCs are progressively making available new telephone carrier technologies such as ISDN and DSL. (Margaret Rouse, 2008) LECS & ILECs Local exchange carriers (LECs) are separated into mandatory LECs (ILECs) and competitive LECs (CLECs).These carriers use the public switched telephone network system for accessing consumers. Unbundling the network helps to create the ability for CLECs to compete with ILECs. This is discussed as local-loop unbundling (LLU or LLUB). MSO Multiple system operators (MSO) are operators of multiple cable television systems. The majority of system operators run cable systems in more than one community. Cable companies offer and promote television services to consumers using radio frequency over HFC hybrid fiber copper and radio frequency over glass networks. ISP ISP is an internet service provider company the offers access to the Internet. An Internet service provider (ISP) is a company that an access ISP connects a consumer to the Internet using copper or fiber-optic cables, or through a wireless...

...Brenda Deni NT1310: Physical Networking Unit 2 Assignment 1 3/30/2014 Service Provider Types * RBOCS: Regional Bell Operating Company Service * Regional Bell operating company (RBOC) is a term describing one of the U.S. regional telephone companies (or their successors) that were created as a result of the breakup of American Telephone and Telegraph Company (AT&T, known also as the Bell System or "Ma Bell") by a U.S. Federal Court consent decree on December 31, 1983. The seven original regional Bell operating companies were Ameritech, Bell Atlantic, BellSouth, NYNEX, Pacific Bell, Southwestern Bell, and US WEST. It is important in telecommunications because RBOCs are generally in competition for digital data and Internet traffic with wireless service providers and cable TV companies. RBOCs are gradually making available new telephone carrier technologies such as ISDN and DSL. * ILEC: Incumbent Local Exchange Carrier * Is a local telephone company in the United States that was in existence at the time of the breakup of AT&T into the Regional Bell Operating Companies (RBOCs), also known as the "Baby Bells." The ILEC is the former Bell System or Independent Telephone Company responsible for providing local telephone exchange services in a specified geographic area. ILECs compete with competitive local exchange carriers (CLEC). When referring to the technical communities ILEC is often used just to mean a telephone provider. * CLEC: Competitive...

...companies and the consumers. With the information from market analysts, alongside the opinions of many involved, the fact of the matter is that there is an impact on every decision made within this mobile market, which will affect the United States in the long run . As we can tell by the history of the rise and fall of cell phone competition in the United States, we started out with numbers of telephone companies, maintaining a healthy competition. However as time passed by, especially in the case of the original AT&T, it all ended up with one company eating up the rest, achieving absolute control over the market. In this particular instance, the original AT&T was forced to split into seven “Baby Bells,” by the United States Department of Justice in a long-running antitrust suit. While this stimulated a growth in competition and awareness of possibilities within the industry, all but one “Baby Bell,” Bell Atlantic, merged together to recreate the behemoth that was AT&T. Luckily, Bell Atlantic grew to become Verizon Wireless, preserving a sense of competition in a vastly unsaturated mobile market. In the market of today, these four players reign supreme, and because of this they have the ability to affect the market as they...

...will limit my discussion to what had been known as “phone service” and not broadcast entities (TV, radio, etc...) nor shall I dwell on the so-called Cable industry. The analysis shall also be primarily focused on the domestic market. Throughout the world, historically the communication industry has overwhelmingly been a monopoly. This was also true in the United States. As AT&T evolved from the late 19th century, except for a year as a nationalized company, existed as a national monopoly. In the so- called Progressive era of the 1910’s, the idea that a natural monopoly would be more efficient and economical than competing systems took hold. The idea of universal service, with rural rates being lower than urban rates (price discrimination). While never a “true” monopoly, with its substantial market share, and restrictions on connecting non-Western Electric equipment to its network, AT&T operated as one. The barriers to entry were primarily economic, the expensive right-of-way access and materials for wired connectivity being first among them. The restriction of un approved devices not being allowed on the AT&T network, limited interconnecting between competitors as well as additional connection & maintenance fees contributed to its dominance. As a monopoly, there were limited phone styles, and little need for deep price reduction through economy of scale or innovation, though state commissions regulated rates. The upside of the additional revenue, Bell Laboratories had been able...

...Eric Satchell NT1330 Service Provider Types Unit 2 Assignment 1 July 3, 2014 Comparing Service Providers There are a lot of companies providing services, but AT&T provided telephone communication to the public. AT&T monopolized the telecommunication industry until the United States took them to court for antitrust and won. AT&T was broken up into eleven smaller companies, call Baby Bells. One of the companies that derived from this law suit was the Regional Bell Operating Company or RBOC. RBOC was a term that described one of the US telephone companies that provided telephone, telegraph, and long distance to the consumers. RBOC is part of a local exchange carrier allowed to compete for business. RBOC services internet service which in turn dealt with digital data. The merging companies provided different types of service based on the Telecommunication Act of 1996. ILEC or incumbent local exchange carrier is a telephone company that provided local telephone communications before the ruling to break up the Ma Bell Company. The FCC ruled that the ILECs must provide other telecommunications service providers access to their equipment to be able to provide a better rate to the consumer. This ruling...

In 1984, Bell System was forced to divest there company into eight smaller companies, in reaction to the United States versus AT&T Anti-Trust suit. As a result of the separation and some misguided acquisitions, AT&T saw its value drop drastically. In 2005 Southwestern Bell Corp. (who had changed its name to SBC) purchased AT&T Corp. who in turn changed its name to AT&T Inc. AT&T Inc. is the largest provider of fixed telephony in the United States. They also provide broadband and subscription television services. (en.wikipedia.org/wiki/AT&T) By the end of 2008, AT&T had discontinued and removed all of its pay telephones. With the decline in phone services, including traditional home phones, the company needed to develop new technologies. The company had to strategize a way back into the consumer’s residence. So, AT&T deployed a new media called U-Verse and extended its high-speed internet into rural areas. ( en.wikipedia.org/wiki/AT&T) Leveling...

...The Regional Bell Operating Companies (RBOC) was formed as a result of the breakup of AT&T and is based on a restructuring agreement that took effect in 1984. The RBOCs were organized into seven regional Bell holding companies called Ameritech, Bell Atlantic, Bell South, Nynex, Pacific Telesis, Southwestern Bell, and US West. (Sheldon, 2001) The Regional Bell operating companies are important to telecommunication because they remove the monopoly that the American Telephone and Telegraph Company (AT&T) had and they provided the fixed line, wireless and data service to the subscribers. The Incumbent Local Exchange Carrier (ILEC) is a local telephone company in the United States that was in existence at the time of the breakup of AT&T into the Regional Bell Operating Companies (RBOCs). (Unknown, Incumbent local exchange carrier, 2012) This ILEC was providing local service when the Telecommunications Act of 1996 was enacted. This forced ILEC to open up their networks to outside competition. The Incumbent Local Exchange Carrier is important to telecommunication because they were the established providers of telephone access. The Competitive Local Exchange Carriers (CLEC) is companies that are known to provide an alternative service to the RBOCs within its territory. CLECs compete against the RBOCs in the local service areas. The Telecommunications Act of 1996 which allowed competition to the ILECs enabled new companies like CLECs to offer voice and data services via both landline...
