This topic have been taken from http://barrtell.com/info-resources/selecting-local-exchange-carriers-services/ One of the most important decisions a telecommunications manager needs to make with respect to establishing service for their external customers is who will provide the internal local service and what type of service(s) are required.

Local exchange service is still at the heart of most companies’ telecommunications structure. The telephone system has grown up with procedures, interfaces, and is now designed for single ownership. The closed nature of the telephone network brings stability that is difficult to break. Competitors be allowed to connect to the ILEC at any feasible point. In fact, it carves into the heart of a system that was never designed for this kind of openness.

The lowest unit in the local exchange is known as a wire center. In larger metropolitan areas, several wire centers combine to make up an exchange. An exchange is a telephone serving area that has uniform rates, services, and tariffs.

Exchanges may be combined into an extended area service (EAS) serving area.

Local Access Transport Area (LATA) is the area in which the BOC is permitted to complete toll calls until the regulatory restrictions are lifted.

The purpose of the local tandem is to allow end offices to route traffic through the tandem if they have insufficient traffic to justify direct trunks or if traffic overflows from direct trunks.

Competitive Local Exchange Carriers (CLECs’) networks are overlaid on the local calling area.

The trunking network connections are reasonably straightforward. The CLEC central office connects to the exchange network just as an ILEC does.

Many CLECs are also in the competitive access provider (CAP) business and have constructed fiber-optic facilities in the metropolitan area. Where direct connection to the end user is possible, many carriers refer to this as a type 1 connection. A type 2 the ILEC collocates in the LEC’s central office and gains access to its cable pairs.

When a CLEC sells service to an ILEC customer, it must first provision the loop, which is done over its own facilities if possible, and if not, over type 2 facilities. A complex form called the local service request (LSR) is used. CLECs required to forecast their requirements for 3 years in advance,

At the heart are eight number databases run by NeuStar, Inc. Under the local number routing architecture, each switch in the country is assigned a 10-digit location routing number (LRN). The first six digits are the NPA and NXX of the switch. Each ported number is correlated in the database with a particular LRN.

On a local call, when the subscriber dials a telephone number, the serving local central office sends a message over the SS7 network to the database to determine which LRN serves the account.

The ILECs generally do not accept a number portability order until the facility is installed, working and tested.

The problem occurs when moving some of your telephone numbers form an ILEC to a CLEC with the intention of retaining few ILEC numbers-perhaps for backup, fax lines, or other purposes. If the numbers are all billed under a pilot number and that number is being ported to a CLEC number, the ILEC may disconnect all of the numbers under that billed number, even though you intend to retain some of them and have not specifically put them on the porting order.

Before you begin the transition from ILEC to CLEC, meet with the CLEC’s project manager and go over everything you can think of that can go wrong.

Agree ahead of time with CLEC who takes responsibility for disconnecting ILEC lines.
Inform the CLEC of every toll-free number you have.
Check directory assistance after the cutover to be sure your listing hasn’t been lost.
Check numbers that you intend to have remain with ILEC to be sure that none of them has been inadvertently ported.
Stay in close touch with the CLEC project manager to be certain the transition date is still on schedule.
Check the phone bills carefully on both the CLEC and the ILEC after porting.
Check the billing carefully to be sure taxes are properly applied.

The question of service revolves around order cycle time, which is particularly important to customers lying at significant distances from the plant. Recent cases where the salesmen had specified « ship via premium transportation », considerably more expensive than the normal shipment cost but with considerable service improvement, had awakened management to the need to improve service especially for distant customers.

...AT&T. It split the company into seven regional companies that handle local exchange service. They are also known as “Baby Bells.” These companies handled almost all of the telephone services across the country. ILEC - Incumbent Local Exchange Carrier. This is a local telephone company that existed when AT&T was broken up into the RBOCS. It was an independent telephone company that provided telephone services in a specific geographical area. ILECs compete with CLECs. CLEC is an acronym for competitive local exchange carriers. They compete with ILECs by providing private line and special access services. They are not affiliated with the RBOCs. Some states especially encourage these companies because they are competitive and the opposite of the monopolies. MSO’s - Multiple system operators. These are defined as an operator of multiple cable television systems. This usually refers to large cable companies that provide service for multiple communities, such as Time Warner Cable, ComCast or Charter Cable. These MSOs provide television service, broadband internet services, and telephone services. ISP - Internet service provider. This is any company that provides customers direct access to the internet. They use copper cable, wireless, or fiber optic cable to give access to the internet for their customers. There are many different ISPs to choose from. Often times either your cable company or your local phone company will be your ISP. Unit 2 Exercise 1 Welcome to New...

...off from AT&T in 1984. The initial seven were Ameritech, BellSouth, Bell Atlantic, Nynex, Southwestern Bell, Pacific Telesis and US West. RBOCS provides a local loop services to most of the United States by functioning as local exchange carriers, while AT&T was left to provide long distance carrier services and to function as an interior exchange carrier. The Telecommunications Act of 1996 allowed RBOCs and independent LECs to compete with existing IXCs for long-distance carrier business, allowed mergers, and essentially opened up the telecommunications market to all kinds of companies, including cable television companies. Of the seven original RBOCs, only five remain today. ILEC also known as incumbent local exchange carrier is a telephone company that provided local services when the Telecommunications Act 1996 was enacted.  ILEC held the regional monopoly on landline service before the market was opened to competitive local exchange carriers, or the corporate successor of such a firm.

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 allowed other telecommunications service provider access to the consumer without owning the local loop that connects the user to the network.

The RBOCs were organized into seven regional Bell holding companies called Ameritech, Bell Atlantic, Bell South, Nynex, Pacific Telesis, Southwestern Bell, and US West. Each RBOC was assigned a specific geographical area, and each geographical area was divided into service areas called LATAs (local access and transport areas).

One basic difference between an Incumbent Local Exchange Carrier and a Competitive Local Exchange Carrier is that the ILEC provides service to the public, and the CLEC has the right to compete for that business but is not indebted to provide the same plane of service.

...Bell, and US WEST. The reason why this was so important was because these companies are what provided local telephone service while AT&T provided the long distance phone service. These are what made up the Local Exchanges or the LEC’s. ILEC or incumbent local exchange carrier was a telephone provider that provided local service prior to the telecommunications act of 1996. These play a major role because these carriers are what own the local loops/exchange and facilities in that area. CLEC’s are the exact same thing except they are the competitor to the ILEC’s but provided their own networking and switches for local service. MSO or Multi system Operator – is owner of multiple cable and satellite television systems. This ties into what an ISP is. An ISP is simply and Internet service provider that provides a mean for accessing the internet. MSO is majorly known for being cable companies, because of this cable companies are providing internet to cable customers (usually as bundles with their plan).

Building a New Structure – NFPA Codes The FCC issues guidelines that govern the installation of telecommunications cabling and the design of communications devices built or used in the US must follow a code of ethic like local, state, county, city and NEC, and that local codes would take precedence over all other installation guidelines. LPFM stations must protect authorized radio broadcast stations on the same channel or frequency, as well as broadcast stations on first or second-adjacent channels above or below the LPFM station's frequency. This protection would be accomplished through the use of minimum distance separation requirements, which are set forth in 47 CFR 73.807. Second, section 79.2 of the FCC’s rules requires that emergency information provided on television be accessible to individuals who have vision disabilities. This means that broadcasters must describe any emergency information that is shown on the screen, and must accompany any emergency information that is not orally described with an aural tone which instructs individuals with vision disabilities to turn to a radio or another source for more information.
