Enhanced Extended Loop (EEL) - V57

History Log

Product Description

Enhanced Extended Loop (EEL) is a combination of the Unbundled Local Loop and Unbundled Dedicated Interoffice Transport (UDIT) and/or Extended-Unbundled Dedicated Interoffice Transport (E-UDIT). The UDIT and E-UDIT offering may vary by state. Refer to your Interconnection Agreement. An EEL can also be a multiplexed dedicated transport circuit that carries multiple loop-transport EELs.

Enhanced Extended Loop (EEL) transport and loop facilities may utilize Digital Signal Level 0 (DS0) - Analog Voice Grade, Digital Signal Level 1 (DS1), Digital Signal Level 3 (DS3), or Optical Carrier Level n (OCn) bandwidths. EEL at OCn bandwidths is requested using the Special Request Process

Enhanced Extended Loop (EEL) provides you with the ability to access either residential or business end-users located in a different CenturyLink™ Wire Center, other than your existing collocation or switch. EEL transport can originate from either your collocation or switch (Point of Presence). The EEL loop must terminate at an end-user's premises/demarcation point in the same Local Access and Transport Area and state as your Collocation or switch. EEL loops can also be connected to a multiplexer on a Local Interconnection Services (LIS) Entrance Facility or to a multiplexer on a LIS Mid Span Meet Point of Interface (POI) with termination points within Legacy Qwest's territory. When an end-user is served by a Remote Serving Unit (RSU) and you are collocated in the RSU's host Central Office (CO), you can provide service to those end-users with an EEL.

DS0 - Analog Voice Grade is a two-point circuit that provides such services as:

  • One Flat Rate Residential (1FR) or One Flat Rate Business (1FB) Plain Old Telephone Service (POTS), off-premises extensions, or off-premises station lines.
  • Private Branch Exchange (PBX) trunks or trunk type tie lines
  • Voice Grade Private Line

Availability

Enhanced Extended Loop (EEL) is available where facilities exist throughout Legacy Qwest's 14-state local service territory.

Terms and Conditions

Enhanced Extended Loops (EEL) are available within the same Local Access and Transport Area (LATA) and state where facilities exist and/or where you have CLEC Requested UNE Construction per the terms and conditions of your Interconnection Agreement. Refer to Negotiation Template Agreement, which addresses options available to you when facilities are not available.

Border town cities are physically located in one state with service provided from a CenturyLink Serving Wire Center located in an adjacent state. EEL requests that involve a border town will be provisioned if facilities are available; and the CLEC wire center and end-user customer location are located within the same CenturyLink Serving Wire Center Area.

Enhanced Extend Loop (EEL) services that extend to designated high voltage (HV) environments are required to have high voltage protection (HVP). HVP devices may be provided by you, the end user, or may be requested from CenturyLink. General High Voltage Protection activities are described in High Voltage Protection.

You may utilize the EEL DS1 Loop product to serve a location where you have multiple end user customers at a single multi-tenant location. EEL Loops are not available for telecommunications services provided directly to you for your own administrative purposes. An unbundled loop is defined as transmission facility between a distribution frame (or its equivalent) in a CenturyLink central office and the loop demarcation point at an end user customer premises.

Service guarantees associated with Private Line/Special Access circuits converted to EEL do not apply after the circuits have been converted to EEL.

Each EEL must carry a significant amount of Local Exchange traffic. You must self-certify that EEL circuits meet one of the three eligibility options from the Federal Communications Commission (FCC) Supplemental Order Clarification, Adopted May 19, 2000, Released June 2, 2000, CC Docket No. 96-98, FCC 00-183, paragraph 22. Key criteria of these options include:

Option 1

  • You must be the exclusive provider of local service to the end-user.
  • Loop/transport combination must originate at the end-user's premises and terminate at your collocation.
  • EEL can not be connected to CenturyLink tariffed services.

Option 2

  • You must handle at least one-third (1/3) of end-user's local traffic.
  • Loop/transport combination must originate at the end-user's premises and terminate at your collocation.
  • For DS1 and higher, at least 50% of each activated channel must have 5% local voice traffic.
  • Entire loop facility must have at least 10% local voice traffic.
  • If the EEL facility includes multiplexing, each of multiplexed facilities must meet above criteria.
  • EEL can not be connected to CenturyLink tariffed services.

Option 3

  • Loop/transport combination does not require collocation.
  • At least 50% of activated channels on a circuit are used to provide local service and 50% of the dial tone channels is local voice traffic.
  • Entire loop facility must have at least 33% local voice traffic.
  • If the EEL facility includes multiplexing, each of multiplexed facilities must meet above criteria.
  • EEL can not be connected to CenturyLink tariffed services.

Federal Communications Commission (FCC) eligibility options to certify a significant amount of Local Exchange Traffic are described in Negotiations Template Agreement.

Additional information about the certification process is available in the Prerequisites section of this web page.

Audits

In order to confirm reasonable compliance with the eligibility requirements of your options, CenturyLink may perform audits of Competitive Local Exchange Carriers (CLEC) records according to the guidelines outlined below. CenturyLink will not audit the local usage on a circuit before converting an existing Private Line/Special Access circuit to an EEL.

  1. Upon 30 days written notice to a CLEC that has purchased loop/transport combinations as Unbundled Network Elements (UNEs) CenturyLink may conduct an audit to determine whether the loop/transport combinations were eligible for UNE treatment at the time of conversion and continue to do so on an ongoing basis.

  2. Competitive Local Exchange Carriers (CLEC) will will make reasonable efforts to cooperate with any audit by CenturyLink and shall provide CenturyLink with relevant records (e.g., network and circuit configuration data, local telephone numbers, call detail records), which demonstrate that CLEC's unbundled loop/transport combination is configured to provide local exchange service in accordance with its certification.

  3. An independent auditor hired and paid for by CenturyLink will perform any audits. If the audit reveals that the CLEC's EEL circuit(s) do not meet or have not met the certification requirements, then the CLEC will reimburse CenturyLink for the cost of the audit.

  4. An audit will be conducted using industry audit standards during normal business hours, unless there is a mutual agreement otherwise.

  5. CenturyLink may not exercise its audit rights with respect to a particular CLEC (excluding affiliates) more than once in any calendar year, unless an audit finds noncompliance. If an audit does find non-compliance, CenturyLink will not exercise its audit rights for 60 days following that audit, and if any subsequent audit does not find non-compliance, then CenturyLink will not exercise its audit rights for the remainder of the calendar year.

  6. At the same time that CenturyLink provides notice of an audit to CLEC, CenturyLink will send a copy of the notice to the FCC.

  7. Audits conducted by CenturyLink for the purpose of determining compliance with certification criteria will not affect or in any way limit any audit rights that CenturyLink may have pursuant to an Interconnection Agreement between the CLEC and CenturyLink.

  8. CenturyLink will not use any other audit rights it may have pursuant to an Interconnection Agreement between the CLEC and CenturyLink to audit for compliance with the local exchange traffic requirements.

  9. CenturyLink will not audit for compliance with the local exchange traffic provisions prior to conversion of a Private Line/Special Access circuit.

  10. The CLEC will maintain appropriate records to support its certification. However, the CLEC has no obligation to keep any records that it does not keep in the ordinary course of business.

Detailed information is available in the Section 9.23.3.7.2 of the Negotiations Template Agreement for the relevant state.

Technical Publications

Technical characteristics, including Network Channel/Network Channel Interface (NC/NCITM) codes are described in Technical Publication, Unbundled Network Element Combinations Including Enhanced Extended Loop (EEL) and Loop Mux Combinations (LMC) 77403.

Pricing

Rate Structure

Recurring charges are comprised of the following rate elements:

  • Enhanced Extended Loop (EEL) Loop
  • Enhanced Extended Loop (EEL) Transport
  • Enhanced Extended Loop (EEL) Multiplexing
  • Interconnection Tie Pair (ITP)
  • Channel Performance at DS0 Analog Voice Grade level

There are three different types of EEL nonrecurring charges. The one that is applied to your service request is dependent upon the work CenturyLink must perform to fulfill your request. The following provides a brief description of each EEL nonrecurring charge.

  • Full installation nonrecurring charges are assessed when provisioning new EELs.
  • A conversion nonrecurring charge is assessed when converting an existing Private Line/Special Access circuit to EEL. This is a billing change only and referred to as Conversion As Is. No Physical work or redesign of the circuit is involved.
  • A rearrangement nonrecurring charge may apply for some Conversion as Specified requests:
    • Roll an existing Private Line circuit from an existing Private Line Multiplexed facility to an existing EEL Multiplexed facility and convert the Private Line circuit to EEL.
    • Reterminate an existing Multiplexed Private Line circuit from one slot to another at the same CLEC's collocation Alternate Point of Termination (APOT); and convert the Multiplexed Private Line circuit to a Multiplexed EEL facility.
    • Redesign an existing Point-to-Point Private Line circuit to ride an existing Multiplexed EEL facility and; convert the Private Line to an EEL Loop.
    • Redesign an unbundled local loop to an EEL Loop connected to a Multiplexed EEL facility when the multiplexer is located in the same wire center as the end user customer's address

Full EEL Installation Nonrecurring charges apply to the following Conversion As Specified requests:

  • The conversion of an existing POTS service to EEL Loop
  • An existing EEL migrating from one CLEC to another.

A rearrangement nonrecurring charge may be assessed on some requests for work to be performed by CenturyLink on an existing EEL:

  • Move an EEL Loop from one slot to another on the same Multiplexed EEL.
  • Reterminate an EEL from one slot to another at your collocation APOT.

For coordinated project installations scheduled to commence out of hours, or rescheduled by a CLEC to commence out of hours, additional nonrecurring charges will be applied to each EEL circuit for the work performed by CenturyLink outside of normal business hours. If this offering is not included in your current ICA, an amendment will be required. Out of Hours Project Coordinated Installations are offered only in those states that contain the appropriate rates found under Miscellaneous Charges in Section 9.20 of Exhibit A for the specific state.

Additional rate information can be located in Exhibit A or the specific rate sheet in your Interconnection Agreement. The nonrecurring charges, either full installation or rearrangement, applied to Conversion as Specified requests are dependent upon the physical work CenturyLink must perform. Full EEL installation nonrecurring charges will apply on all Conversion as Specified requests unless your current Interconnection Agreement includes the EEL rearrangement nonrecurring charge. If you wish to amend your current Interconnection Agreement to include either EEL or the rearrangement nonrecurring charge, contact your CenturyLink Service Manager.

When providing an EEL to an end-user served from an RSU, the facility between the host office and the RSU is billed at EEL transport rates. If the RSU has the same NPA NXX as the host switch, CenturyLink will zero rate the recurring cost of the transport between the host and the remote office.

For Private Line/Special Access Services that are converted to EEL, minimum service period, termination liability and shortfall charges for the product from which the circuit is being converted will apply and will be assessed as described in the individual state Tariffs/Catalogs Price Lists. If you wish to convert services to EEL, the conversion of these services will not be delayed due to the applicability of minimum service period, shortfall or termination liability charges.

Information regarding Geographic Deaveraging is available in Geographic Deaveraging - General Information.

Rates

Wholesale rates for this product or service, including tariff references and any applicable discounts, are provided in your current Interconnection, Resale, Commercial, or other governing agreement.

Tariffs, Regulations, and Policies

Tariffs, regulations and policies are located in the state specific Tariffs/Catalogs/Price Lists.

Enhanced Extended Loops (EEL) are provisioned where existing facilities are available and/or where you have CLEC Requested UNE Construction per the terms and conditions of your Interconnection Agreement.

When you submit your service request and facilities are not available, your request may be held for 90 business days. For exceptions and detailed information, refer to the Provisioning and Installation Overview.

Co-mingling is the FCC's term for "combining loops or loop-transport combinations with tariffed services." Combining tariffed services such as Private Line/Special Access or Switched Access Services with Unbundled Network Elements (UNEs), i.e., EELs, is prohibited. Circuits connected to a CenturyLink tariffed service will not be converted to or provisioned as an EEL.

Eligible circuits that are converted from Private Line/Special Access Service to EEL will retain all optional features and functions that were associated with the existing service as requested from the tariff(s). After a circuit has been converted to EEL, if you wish to make design changes to that service, the change requested must be in compliance with the design requirements identified in Technical Publication Unbundled Network Element Combinations Including Enhanced Extended Loop (EEL) and Loop Mux Combinations (LMC), 77403. If the change is outside of the scope of Technical Publication Unbundled Network Element Combinations Including Enhanced Extended Loop (EEL) 77403 the Special Request Process must be followed.

The Special Request (SR) process is used when you are requesting nonstandard combination of previously available UNEs, or certain UNEs that CenturyLink does not offer as a standard product but have been identified by the Federal Communications Commission (FCC) or State Commission as network elements. Special Requests information is described in Bona Fide Request (BFR) and Special Request (SR) Processes.

Implementation

Product Prerequisites

If you are a new CLEC and are ready to do business with CenturyLink, view Getting Started as a Facility-Based CLEC. If you are an existing CLEC wishing to amend your Interconnection Agreement or New Customer Questionnaire, additional information is located in the Interconnection Agreement.

Before submitting your first request to either convert or provision new EEL service, you should review your Interconnection Agreement. If your Interconnection Agreement includes provisions for UNE combinations, all of the UNEs (e.g., loop and transport) making up the EEL and all of the appropriate recurring and nonrecurring billing elements comprised in an EEL, an amendment to your Interconnection Agreement is not required. The following EEL billing elements must be included your Interconnection Agreement:

  • Interconnection Tie Pair (ITP) for connection to your collocation. Only recurring charges apply.
  • E-UDIT for connection to your Wire Center. Only recurring charges apply. E-UDIT is transport between the appropriate CenturyLink Serving Wire Center and another carrier's wire center, distinct from an end-user, and within Legacy Qwest's territory. E-UDIT cannot traverse a CenturyLink Wire Center. The location of the other carrier will be considered a carrier wire center only if it meets the following criteria:
    • Its location has Vertical and Horizontal (V&H) coordinates
    • The wire center contains a device that switches traffic, or a node leading to such a switch
    • The switch is registered with a Common Language® Location Identifier (CLLI™) Code listed in the Local Exchange Routing Guide (LERG™)
  • Unbundled Dedicate Interoffice Transport (UDIT) for transport between CenturyLink Wire Centers. Recurring and nonrecurring charges will apply. In states where the distinction between UDIT and E-UDIT has been removed, the E-UDIT portion of the EEL will have the same rate structure as UDIT.
  • Digital Signal Level 0 (DS0) , DS1, DS3 Unbundled Local Loops to provide the loop segment to your end-user. Recurring and nonrecurring charges apply. Your Interconnection Agreement must include the nonrecurring rate for Basic Installation with Cooperative Testing.
  • Digital Signal Level 1 (DS1) to DS0 and DS3 to DS1 Multiplexing for the installation of Multiplexed EELs. Both recurring and nonrecurring charges apply.
  • Channel Performance for the installation of DS0 - Analog Voice Grade EEL circuits. Recurring and nonrecurring charges will apply.

An EEL amendment may be required to include, full nonrecurring charges for loop, transport, and multiplexing as described in the Negotiations Template Agreement for the relevant state and will apply when converting Private Line/Special Access circuits to EEL and when provisioning new EELs.

If you are amending your Interconnection Agreement, a New Customer Questionnaire must be updated and provided to your CenturyLink Service Manager.

Before accepting an EEL conversion service request, CenturyLink will perform a pre-qualification process to determine each circuit's eligibility to convert to EEL. The pre-qualification process is not an audit of local usage. As part of the pre-qualification process you must:

Spreadsheets that do not contain all of the required information or are not accompanied with the Certification of Private Line/Special Access Services to Unbundled Network Elements Platform Letter will be rejected.

Once the Certification of Private Line/Special Access Services to Unbundled Network Elements Combination Letter and Pre-Qualification UNE-Combination Spreadsheet have been received, you will receive pre-qualification feedback based on the following intervals:

Number of Circuits Response Interval
1 - 28 5 business days
29 - 60 6 business days
61 - 99 7 business days
100 or more Negotiated with your CenturyLink Service Manager

If you have a limited number of circuits to pre-qualify for conversion and you want to negotiate an alternative qualification process contact your CenturyLink Service Manager.

The pre-qualification process will validate the following:

  • The circuit exists in CenturyLink billing records.
  • The end-user name and address on the spreadsheet match the CenturyLink billing records.
  • The circuit has transport.
  • The circuit terminates at an end-user's premises.
  • If certified under Option 1 or 2, the circuit involves collocation.
  • Each circuit has been certified with one of the three FCC options for Local Exchange Traffic.
  • If the circuit is 'co-mingling' or connected to a CenturyLink tariffed service. Circuits will be evaluated for co-mingling up through the highest customer owned facility. Combining Private Line/Special Access or Switched Access Services with EEL is prohibited.

Upon completion of the pre-qualification process, CenturyLink will provide a validation code to you for circuits that qualify for conversion to EEL.

Pre-Ordering

General pre-ordering activities are described in the Pre-Ordering Overview.

Requirements for pre-ordering are described in Local Service Ordering Guidelines (LSOG) Pre-Order.

The Interconnect Mediated Access (IMA) User's Guide specifically details the information available for the pre-ordering functions.

CenturyLink recommends use of pre-ordering functionality to assist in achieving increased service request flow through and accuracy that will result in reduced service request rejects.

Pre-Ordering activities applicable to EEL include:

  • Validate address
  • Check facility availability
  • Customer Service Record (CSR) retrieval
  • Query Raw Loop Data (RLD) tools
    • RLD via IMA
    • Wire Center RLD

You may verify if the DS1 or DS3 facility is available by doing a high capacity facility check using the inquiry function in IMA. Information is available in the IMA User's Guide.

CSR retrieval is available through IMA for the following Local Service Request (LSR) ACT types:

  • C = Change
  • D = Disconnect
  • V = Conversion as specified

On-line CSR retrieval is not available for 'Conversion as is' requests as the account resides in the Integrated Access Billing System (IABS™). IMA does not have the ability to access records in IABS.

If you are unable to locate the CSR, contact the CenturyLink Customer Service Inquiry and Education (CSIE) and select the Centrex and Complex Resale Option to reach the appropriate workgroup.

When contacting the CenturyLink CSIE, be prepared to provide:

Depending on your needs, the CenturyLink CSIE can:

  • Provide you with the account number of the facility so you can find the CSR in IMA
  • Fax, mail or e-mail the CSR to you
  • Review the CSR with you on the telephone.

The RLD Tools provide the physical characteristics of the facility at either the Wire Center level or at the individual loop level. Data may include, but is not limited to, the physical characteristics by segment:

  • CLLI Code
  • Load Coils
  • Bridged Taps
  • Wire Gauge
  • Cable and Pair make-up
  • Spare Facility

The Wire Center RLD Tool provides the physical characteristics of the facilities for a Wire Center.

The IMA RLD Tool provides loop specific information. This tool also enables you to obtain the physical characteristics of the facilities.

Information regarding the IMA RLD Tool is described in the IMA User's Guide. The IMA Loop Qualification and Raw Loop Data-CLEC Job Aid provides loop makeup information and instructions on how to use the IMA based loop qualification tools and the Wire Center RLD Tool. The Wire Center RLD Tool requires a digital certificate.

It is important to understand the network topology, in understanding the difference between a 'stand alone' Serving Wire Center or Serving Central Office, a Host Central Office, a remote and a Remote Service Unit (RSU). Generally, Serving Wire Center is a term used to describe a Central Office that directly serves a specific geographic area of end-users. In this circumstance, there are no intermediary offices between the end-user and the Central Office. Contrarily, Host Office is a term generally used to describe a Central Office that directly serves sub-tending office(s) in addition to its own end-users. For example, the Dry Creek, Colorado Central Office has some direct end-users and is also the originating end of the cable that fed the Tech Center in its remote status (not as a stand-alone Serving Central Office). A remote is a piece of field equipment attached to the Serving Wire Center that provides capability that the end-user's distance would otherwise prohibit. Thru time, if or when a remote grows to accommodate a significant number of its own end-users, it can be deemed a sub-tending office. This sub-tending office is generally referred to as an RSU and becomes a Serving Central Office (i.e., no longer a remote, but a Remote Service Unit).

A distinct cable naming convention is used when an end-user is not directly served by the Host Central Office (i.e., served from a remote), an "EX" prefix will appear in the end-users distribution cable pair (e.g., F2 ca EXA7). The "EX" prefix designates the cable that extends from a remote to the end-user. When an end-user is served from a Remote Serving Unit (RSU), Unbundled Local Loops are available only when you are collocated in the same RSU that your end-user is served by. If you are not collocated in the same RSU as an end-user, Enhanced Extended Loops (EELS) are available to serve end users that have EX cable designations in their distribution pair. Where an end-user is fed out of a Serving Central Office other than one where the Collocation is present, an EEL is also used.

Unbundled Loops are available when you are collocated in the same Serving Central Office that your end-user is served by. Generally, once a remote becomes a Serving Central Office, you can now collocate in the RSU and serve the customer with an Unbundled Loop (UBL) or continue to serve from the old Host Central Office under the EEL.

In rare instances where the facility between the Host office serving that RSU and the end user has been included in the Unbundled Loop cost models, CenturyLink will continue to make Unbundled Loops available to you to serve that end user. These instances will need to be evaluated on an ICB basis, contact your CenturyLink Sales Executives for assistance if you believe you have such an instance. The Chandler Main AZ central office is one such exception. Unbundled Loops are available in Chandler Main when an "EX" prefix appears in the end-users distribution cable pair.

Enhanced Extended Loop (EEL) Conversion Requests

Enhanced Extended Loop (EEL) ‘Conversion As Is’ is the conversion of an existing Private Line/Special Access circuit.  The conversion does not require redesign of the circuit and will not disrupt service.  There is a change in billing and the service code modifiers within the circuit ID.

A separate service request is required for each 'Conversion As Is' circuit requested. The ACT field of the LSR must show a 'W' for 'conversion as is'. In the remarks section of each LSR, you must specify:

  • EEL
  • 'Circuit is qualified with validation code ___.'

Enhanced Extended Loop (EEL) Conversion as Specified requires CenturyLink to redesign and perform physical work on a circuit at the time of conversion from Private Line/Special Access to EEL. The end user address must remain the same for all Conversion as Specified requests. All work must be performed in the same CenturyLink Wire Center.

The following options are available with Conversion As Specified:

  • Roll an existing Private Line circuit from an existing Private Line Multiplexed facility to an existing EEL Multiplexed facility in the same CenturyLink Wire Center; and convert the Private Line circuit to EEL.
  • Reterminate an existing Private Line circuit from one slot to another at the same CLEC's collocation Alternate Point of Termination (APOT); and convert the Private Line circuit to a Multiplexed EEL facility.
  • Redesign an existing Point-to-Point Private Line circuit to ride an existing Multiplexed EEL facility and; convert the Private Line to an EEL Loop. All work must be performed in the same CenturyLink Wire Center where the multiplexer is located.
  • Redesign an existing DS1 Private Line Transport circuit, eliminating the DS1 transport, and re-terminate the DS1 Loop to ride an existing DS3 Multiplexed EEL facility. The DS1 Private Line Transport circuit will be converted to a DS1 EEL Loop. The DS3 multiplexer must be located in the same CenturyLink wire center that serves the end user address.
  • An existing EEL can be moved from one CLEC to another. The end-user address on point-to-point EELs and the multiplexing location on Multiplexed EEL facilities must remain the same.
  • The conversion of an existing POTS service to EEL Loop is offered at the DS0 Analog Voice grade level. If your request involves a multiplexed facility, your request to convert an existing or order a new DS1 multiplexed EEL facility must be submitted prior to the request to convert POTS service (e.g., 1FR or 1FB) to an EEL DS0 Analog Voice Grade loop. The end user address of the POTS service must remain the same.
  • Convert an existing Unbundled Loop to EEL loop; and reterminate from the collocation to an existing EEL multiplexed facility within the same wire center.

CenturyLink will follow the same pre-qualification process followed on Conversion As Is requests on all EEL Conversion as Specified requests. After CenturyLink has completed the prequalification process, CenturyLink will provide a validation code to you. This validation code must be included on your LSR along with one of the three FCC options to certify local use.

Conversions as Specified with circuits converting from Private Line to EEL require an Access Service Request (ASR) and an LSR. An ASR is required to disconnect the existing Private Line circuit. The activity field must be populated with a "D". The RPON field must be populated to relate the ASR to the LSR and the REMARKS section of the ASR must state:

  • "EEL"
  • Reuse facilities from related ASR PON#_____
  • Physical work required.
  • Validation code _____
  • FCC Option # ____.

An LSR is required to establish the circuit as EEL. The activity field on the LSR must be populated with 'V'. Your LSR must include the new information associated with the Conversion as Specified request to establish the circuit as an EEL. The REMARKS section of the LSR must state:

  • "EEL"
  • Reuse facilities from related ASR PON#_____
  • Physical work required.
  • Validation code _____
  • FCC Option # ____.

Enhanced Extended Loop (EEL) New Requests

A separate LSR is required for each new EEL circuit requested. The ACT field of the LSR must show an "N" for "new service", in the REMARKS section of the LSR, you must specify:

  • "EEL"
  • FCC Option # ____.

New EELs will not be provisioned to, connected to or combined with tariffed services. If a service request is received requesting that an EEL be connected or combined with tariffed services, the request will be rejected.

Enhanced Extended Loop (EEL) Rearrangement Requests

The CLEC and the end-user address must remain the same on all rearrangement requests. All work performed must be in the same CenturyLink Wire Center. Rearrangements to an existing EEL may include the following:

  • Move an EEL Loop from one slot to another on the same Multiplexed EEL.
  • Roll an EEL Loop from one Multiplexed EEL to a different Multiplexed EEL in the same CenturyLink Wire Center.

CenturyLink offers Out of Hours Project Coordinated Installations. CenturyLink's standard installation hours are 8:00 a.m. to 5:00 p.m., Monday through Friday, excluding CenturyLink holidays. Installations requested outside of these hours are considered to be Out of Hours Project Coordinated Installations. You must first contact your assigned CenturyLink Service Manager to ensure you have provisions in your existing ICA that allow for Out of Hour Project Coordinated Installations of EEL circuits. An amendment may be required before submitting your first request.

The date and time of the project coordinated installation requires up-front planning and must be negotiated between CenturyLink and the CLEC. Contact your CenturyLink Service Manager to negotiate project dates and times. All requests will be processed on a first come, first served basis and are subject to CenturyLink's ability to meet a reasonable demand. Considerations such as volumes, system down time, switch upgrades, switch maintenance, and contention with other CLECs requesting the same appointment times in the same switch must be reviewed. To request Out of Hours Project Coordinated Installations, you will submit an LSR designating "Out of Hours Project Coordinated Installation" in the Remarks section of the LSR.

When the Special Access circuit converts to an EEL the circuit is removed from the IABS Billing Account Number (BAN) (for billing purposes only) effective with the completion date of the EEL conversion service request. Charges will be prorated from the service order completion date to the bill date for circuits converted to EEL.

The account will be established in CRIS, effective with the completion date of the EEL conversion and/or new service request.

The Universal Service Order Codes (USOCs) will be a combination of retail (i.e., tariffed) and EEL specific USOCs. The recurring multiplexing, transport (fixed and per mile) and the loop (channel termination) USOCs are retail USOCs utilizing the rates from your Interconnection Agreement. All other EEL USOCs are product specific and also utilize the rates from your Interconnection Agreement.

Enhanced Extended Loop (EEL) are billed on a CRIS Summary Bill on a month-to-month basis. Term contracts are not available.

Loss and Completion Reports are based on loss and gain account activity. Completion notification, including Loss and Completion Reports, is described in Billing Information - Additional Outputs - SMDR, Completion Report, Loss Report.
