Dark Fiber Loop 2.8.4.1 Dark Fiber Loop is an unused optical transmission facility, without attached signal regeneration, multiplexing, aggregation or other electronics, from the demarcation point at an End User’s premises to the End User’s serving wire center. Dark Fiber Loops may be strands of optical fiber existing in aerial or underground structure. BellSouth will not provide line terminating elements, regeneration or other electronics necessary for AFN to utilize Dark Fiber Loops.
Unbundled Loops 2.1.1 BellSouth agrees to offer access to unbundled loops pursuant to the following terms and conditions and at the rates set forth in Attachment 11.
Unbundled Voice Loops (UVL) may be provisioned using any type of facility that will support voice grade services. This may include loaded copper, non-loaded copper, digital loop carrier systems, fiber/copper combination (hybrid loop) or a combination of any of these facilities. BellSouth, in the normal course of maintaining, repairing, and configuring its network, may also change the facilities that are used to provide any given voice grade circuit. This change may occur at any time. In these situations, BellSouth will only ensure that the newly provided facility will support voice grade services. BellSouth will not guarantee that Southern Telecom will be able to continue to provide any advanced services over the new facility. BellSouth will offer UVL in two different service levels - Service Level One (SL1) and Service Level Two (SL2).
Unbundled Voice Loop SL2 (UVL-SL2) loops may be 2-wire or 4-wire circuits, shall have remote access test points, and will be designed with a DLR provided to NuVox. SL2 circuits can be provisioned with loop start, ground start or reverse battery signaling. OC is provided as a standard feature on SL2 loops. The OC feature will allow NuVox to coordinate the installation of the loop with the disconnect of an existing customer‟s service and/or number portability service. In these cases, AT&T will perform the order conversion with standard order coordination at AT&T‟s discretion during normal work hours.
Unbundled Sub-Loop Feeder 2.8.4.1 Unbundled Sub-Loop Feeder (USLF) provides connectivity between BellSouth's central office and cross-box (or other access point) that serves an end user location.
2.8.4.2 USLF utilized for voice traffic can be configured as 2-wire voice (USLF-2W/V) or 4-wire voice (USLF-4W/V).
2.8.4.3 USLF utilized for digital traffic can be configured as 2-wire ISDN (USLF-2W/I); 2-wire Copper (USLF-2W/C); 4-wire Copper (USLF-4W/C); 4-wire DS0 level loop (USLF-4W/D0); or 4-wire DS1 and ISDN (USLF-4W/DI).
2.8.4.4 USLF will provide access to both the equipment and the features in the BellSouth central office and BellSouth cross box necessary to provide a 2W or 4W communications pathway from the BellSouth central office to the BellSouth cross- box. This element will allow for the connection of Lightyear’s loop distribution elements onto BellSouth's feeder system.
Unbundled Voice Loops (UVLs) 2.2.1 BellSouth shall make available the following UVLs:
Unbundled Digital Loops 2.3.1 BellSouth will offer Unbundled Digital Loops (UDL). UDLs are service specific, will be designed, will be provisioned with test points (where appropriate), and will come standard with OC and a DLR. The various UDLs are intended to support a specific digital transmission scheme or service.
2.3.2 BellSouth shall make available the following UDLs, subject to restrictions set forth herein:
Dark Fiber 8.1 Access to unbundled Dark Fiber will be provided by Verizon, where existing facilities are available at the requested availability date, in the loop, subloop and interoffice facilities (IOF) portions of the Company's network. Access to Dark Fiber will be provided in accordance with, but only to the extent required by, Applicable Law. Except as otherwise required by Applicable Law, the following terms and conditions apply to Verizon's Dark Fiber offering.
8.2 A “Dark Fiber Loop” consists of continuous fiber optic strand(s) in a Verizon fiber optic cable between the fiber distribution frame, or its functional equivalent, located within a Verizon Wire Center, and Verizon’s main termination point, such as the fiber patch panel located within a Customer premise, and that has not been activated through connection to the electronics that “light” it, and thereby render it capable of carrying Telecommunications Services. In addition to the other terms and conditions of this Agreement, the following terms and conditions also shall apply to Dark Fiber Loops:
8.2.1 Verizon shall be required to provide a Dark Fiber Loop only where (1) one end of the Dark Fiber Loop terminates at Z-Tel's collocation arrangement and (2) the other end terminates at the Customer premise. A CLEC demarcation point shall be established either in the main telco room of a building where a Customer is located or, if the building does not have a main telco room, then at a location to be determined by Verizon. Verizon shall connect a Dark Fiber Loop to the demarcation point by installing a fiber jumper.
8.2.2 Z-Tel may access a Dark Fiber Loop only at a pre-existing hard termination point of such Dark Fiber Loop, and Z-Tel may not access a Dark Fiber Loop at any other point, including, but not limited to, a splice point. Verizon will not introduce additional splice points or open existing splice points to accommodate a CLEC’s request. Unused fibers located in a cable vault or a controlled environment vault, manhole or other location outside the Verizon Wire Center, and not terminated to a fiber patch, are not available to Z-Tel.
8.2.3 A strand shall not be deemed to be continuous if splicing is required to provide fiber continuity between two locations. Dark Fiber will only be offered on a route-direct basis where facilities exist (i.e., no intermediate offices).
8.2.4 Verizon shall perform all work necessary to install a cross connection or a fiber jumper, including, but not limited to, the work necessary to connect a dark fiber to a demarcation point, a fiber distribution frame or a POT bay.
8.2.5 At the Customer premise, unused fibers are not available to Z-Tel pursuant to this Attachment unless such fibers terminate on a fiber patch panel. Unused fibers in a fiber splice point located outside the Customer premise are not available to Z-Tel.
8.2.6 Dark Fiber will be offered to Z-Tel in the condition that it is available in Verizon's network at the time that Z-Tel submits its request (i.e., "as is"). In addition, Verizon shall not be required to convert lit fiber to Dark Fiber for Z-Tel's use.
8.2.7 Spare wavelengths on fiber strands, where Wave Division Multiplexing (WDM) or Dense Wave Division Multiplexing (DWDM) equipment is deployed, are not considered to be spare Dark Fiber Loops and, therefore, will not be offered to Z-Tel as Dark Fiber.
8.2.8 Z-Tel shall be responsible for providing all transmission, terminating and regeneration equipment necessary to light and use Dark Fiber.
8.2.9 Z-Tel may not resell Dark Fiber purchased pursuant to this Attachment to third parties.
8.2.10 In order for Verizon to continue to satisfy its carrier of last resort (COLR) obligations under Applicable Law and/or to preserve the efficiency of its network, Verizon will limit Z-Tel to leasing a maximum of twenty-five percent (25%) of the Dark Fiber in any given segment of Verizon's network during any two-year period. In addition, except as otherwise required by Applicable Law, Verizon may take any of the following actions, notwithstanding anything to the contrary in this Agreement:
8.2.10.1 Revoke Dark Fiber leased to Z-Tel upon a showing of need to the Commission and twelve (12) months' advance written notice to Z-Tel; and
8.2.10.2 Revoke Dark Fiber leased to Z-Tel upon a showing to the Commission that Z-Tel underutilized fiber (less than OC-12) within any twelve (12) month period.
8.2.10.3 Verizon may reserve Dark Fiber for maintenance purposes, or to satisfy Customer orders for fiber related services or for future growth. Verizon reserves and shall not waive, Verizon’s right to claim before the Commission that Verizon should not have to fulfill a Z-Tel order for Dark Fiber because that request would strand an unreasonable amount of fiber capacity, disrupt or degrade service to Customers or carriers other than Z-Tel, or impair a Verizon obligation to serve as a carrier of last resort. 8.2.11 Z-Tel may not reserve Dark Fiber.

Provisional Interconnection Service Upon the request of Interconnection Customer, and prior to completion of requisite Interconnection Facilities, Network Upgrades, Local Upgrades, or system protection facilities Interconnection Customer may request limited Interconnection Service at the discretion of Transmission Provider based upon an evaluation that will consider the results of available studies, which terms shall be memorialized in the Interconnection Service Agreement. Consistent with Tariff, Part VI, Subpart B, section 212.4, Interconnection Customer may execute the Interconnection Service Agreement, request dispute resolution or request that the Interconnection Service Agreement be filed unexecuted with the Commission. Transmission Provider shall determine, through available studies or additional studies as necessary, whether stability, short circuit, thermal, and/or voltage issues would arise if Interconnection Customer interconnects without modifications to the Generating Facility or the Transmission System. Transmission Provider shall determine whether any Interconnection Facilities, Network Upgrades, Local Upgrades, or system protection facilities that are necessary to meet the requirements of NERC, or any applicable Regional Entity for the interconnection of a new, modified and/or expanded Generating Facility are in place prior to the commencement of Interconnection Service from the Generating Facility. Where available studies indicate that such Interconnection Facilities, Network Upgrades, Local Upgrades, and/or system protection facilities that are required for the interconnection of a new, modified and/or expanded Generating Facility are not currently in place, Transmission Provider will perform a study, at the Interconnection Customer’s expense, to confirm the facilities that are required for Provisional Interconnection Service. The maximum permissible output of the Generating Facility shall be studied and updated annually and at the Interconnection Customer’s expense. The results will be communicated to the Interconnection Customer in writing upon completion of the study. Interconnection Customer assumes all risk and liabilities with respect to the Provisional Interconnection Service, including changes in output limits and Interconnection Facilities, Network Upgrades, Local Upgrades, and/or system protection facilities cost responsibilities.
