What is the difference between an ILEC and a CLEC?
The basic difference between an ILEC and a CLEC is that an ILEC has a duty to provide a telephone service to the public whereas a CLEC has the right to compete for that business, but is not obliged to provide the same level of service. All LECs must abide by the FCC regulations that affect that class of carrier; the regulations affecting ILECs are slightly different than the regulations affecting CLECs. Sometimes the FCC will change the status of a CLEC to an ILEC if it serves the best interests of the public. An example would be if the CLEC exists in an area of the country that is inadequately served by existing ILECs. Thanks Amit Singh Luthra amitsinghluthra@yahoo.co.in

How many telephone companies in the us?
It really depends on what you want to know, there are several different classifications of telephone companies, there is the RBOC (regional bell operating company), ILEC (incumbent local exchange company), CLEC (competitive local exchange companies) and independent phone companies. That really is just the hardline companies, with the popularity of wireless carriers, the number is just going up.In 2000, I had to get a Y2K certification letter from each carrier in the entire state of Kansas, I know at that time, there were 62 phone companies in just Kansas, cant imagine what the total is for more populated states.
How can you become a metro pcs customer without changing phones and without changing phone numbers?
This is a 2-part question, so here is a 2-part answer:Part 1: Keeping your number is easy -- the FCC has "Local Number Portability" rules that literally force carriers to allow you to change providers and keep your phone number. You can even transfer land-line to cellular or back. (NOTE: Companies do not have to allow porting IN, but they do have to support the porting OUT of numbers. In my experience, only the ILEC (your local wired phone company) is likely to not allow porting a number IN to their system).Part 2: Keeping your existing phone is a harder nut to crack. There are basically 4 types (major types) of cell phone service in the US (TDMA, PCS, CDMA, and Analog). If your phone is a "multi-mode" phone, it is possible that it can be programmed to work in the MetroPCS networks. If not, and you don't have a phone capable already of working on a PCS system, you're outta luck. (If your phone's relatively new, look on the MetroPCS site to see if they sell that phone (or one REALLY REALLY like it)... if so, you may very well be in luck -- but don't count on it.That is the "gocha" of MetroPCS service -- unlike most other cellular companies that charge you over time (with higher monthly fees) for your hardware, MetroPCS makes you pay up front -- and their prices (for the phones) are not discounted in the least!I hope this helps to answer your question!
What is a dedicated-circuit switched network?
A distinct physical circuit dedicated to directly connecting devices, such as multiplexers, PBXs, and host computers. A dedicated circuit, also known as a leased line, can be provisioned over a private network comprising facilities owned by the end user organization, although it more typically is in the form of a leased line provisioned over a public network. In the latter case, the circuit includes an access circuit, or local loop, that connects the originating device at the customer premises to the service provider's point of presence (POP) at the edge of the carrier network. In the case of an incumbent local exchange carrier (ILEC), the POP typically is housed in a central office (CO). At the POP, the access circuit terminates in a wire center, where it is cross-connected directly to a long-haul transport circuit, bypassing any switching devices. The long haul portion of the dedicated circuit typically comprises multiple interconnected links and terminates in a POP at the egress edge of the network, where it is crossconnected to another access circuit that connects to the premises housing the destination device. A dedicated circuit offers the advantages of dedicated availability, dedicated bandwidth, and excellent performance overall. Because a dedicated circuit is not in shared public use but is dedicated to the requirements of a specific customer, it tends to be expensive, with the cost sensitive to bandwidth and distance. The cost, however, is typically a flat rate, with no usage-sensitive component; therefore, the end user organization can use the circuit constantly to maximum capacity at the same cost as if it were to not use the circuit at all. The nature of the traffic over a dedicated circuit generally is not restricted, and can include voice, computer data, facsimile, image, video, and multimedia traffic. The ability to integrate such a wide variety of traffic over a single facility offers considerable efficiencies. A multi-site user organization might consider a private, leased line network to interconnect the sites. However, the process of designing such a network can be difficult, as it is necessary to determine the points of termination in the optimal topology, the correct number of circuits, and the bandwidth requirements of each.When the design is established, the provisioning time required by the carrier can be quite lengthy. As a dedicated circuit involves a specific set of network elements, the circuit is susceptible to disruption. Therefore, backup circuits or services are required to ensure connectivity in the event of either a catastrophic failure or serious performance degradation. Organizations with intense communications requirements commonly consider dedicated circuits to be viable alternatives to switched circuits. Large data centers that communicate intensively in support of applications such as data backup traditionally have opted for dedicated circuits. Large multi-site end user organizations often use dedicated circuits known as tie trunks to tie together multiple PBXs. In such applications, the advantages of assured availability, capacity, and performance in support of mission-critical, time-sensitive applications, particularly when coupled with low comparative cost, can outweigh considerations of configuration difficulty and risk of circuit failure. Dedicated circuits sometimes are referred to as nailed-up circuits because, in bygone days, the twisted-pair copper physical circuits were hung from nails driven in the walls of the carrier's wire centers.
