An 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), 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. GTE was the second largest ILEC after the Bells, but it has since been absorbed into Verizon, a RBOC. ILECs compete with competitive local exchange carriers (CLEC). When referring to the technical communities ILEC is often used just to mean a telephone provider.
In Canada, the term ILEC refers to the original telephone companies such as Telus (BC Tel and AGT), SaskTel, Manitoba Telephone Systems (MTS Allstream), Bell Canada Enterprises and Aliant.
An ILEC, with respect to an area in the United States, is a local exchange carrier (LEC) that:
- On the date of enactment of the Telecommunications Act of 1996, provided telephone exchange service in such area
- And on such date of enactment, was deemed to be a member of the exchange carrier association pursuant to the Code of Federal Regulations (C.F.R) Title 47, section 69.601(b).
- Or is a person or entity that, on or after such date of enactment, became a successor or assignee of a member described in the previous bullet.
The Federal Communications Commission (FCC) may, by rule, provide for the treatment of an LEC (or class or category thereof) as an ILEC if:
- Such carrier occupies a position in the market for telephone exchange service within an area that is comparable to the position occupied by a carrier described previously
- Such carrier has substantially replaced an ILEC described previously
- Such treatment is consistent with the public interest, convenience and necessity
ILECs have the same duties of a LEC and in addition:
- Duty to negotiate - The duty to negotiate in good faith the particular terms and conditions of agreements to fulfill the duties described for a LEC and the specific ones for the ILEC. The requesting telecommunications carrier also has the duty to negotiate in good faith the terms and conditions of such agreements.
- Interconnection - The duty to provide, for the facilities and equipment of any requesting telecommunications carrier, interconnection with the LEC's network -
- For the transmission and routing of telephone exchange service and exchange access
- At any technically feasible point within the carrier's network
- That is at least equal in quality to that provided by the LEC to itself or to any subsidiary, affiliate or any other party to which the carrier provides interconnection
- On rates, terms and conditions that are just, reasonable and nondiscriminatory, in accordance with the terms and conditions of the agreement
- Unbundled access - The duty to provide, to any requesting telecommunications carrier for the provision of a telecommunications service, nondiscriminatory access to network elements on an unbundled basis at any technically feasible point on rates, terms and conditions that are just, reasonable and nondiscriminatory in accordance with the terms and conditions of the agreement. An ILEC shall provide such unbundled network elements in a manner that allows requesting carriers to combine such elements in order to provide such telecommunications service.
- Resale - The duty
- To offer for resale at wholesale rates any telecommunications service that the carrier provides at retail to subscribers who are not telecommunications carriers
- Not to prohibit, and not to impose unreasonable or discriminatory conditions or limitations on, the resale of such telecommunications service,
- Notice of changes - The duty to provide reasonable public notice of changes in the information necessary for the transmission and routing of services using that local exchange carrier's facilities or networks, as well as of any other changes that would affect the interoperability of those facilities and networks.
- Colocation - The duty to provide, on rates, terms and conditions that are just, reasonable and nondiscriminatory, for physical colocation of equipment necessary for interconnection or access to unbundled network elements at the premises of the local exchange carrier, except that the carrier may provide for virtual colocation if the LEC demonstrates that physical colocation is not practical for technical reasons or because of space limitations.
