Voice Grade Unbundled Copper Sub-Loop Unbundled Sub-Loop Distribution – Intrabuilding Network Cable (aka riser cable)
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 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.
Unbundled Copper Loop – Designed (UCL-D) 2.4.2.1 The UCL-D will be provisioned as a dry copper twisted pair (2- or 4-wire) Loop that is unencumbered by any intervening equipment (e.g., filters, load coils, range extenders, digital loop carrier, or repeaters).
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 NewPhone. SL2 circuits can be provisioned with loop start, ground start or reverse battery signaling. OC is provided as a standard feature on XX0 Xxxxx. The OC feature will allow NewPhone to coordinate the installation of the Loop with the disconnect of an existing customer’s service and/or number portability service. In these cases, BellSouth will perform the order conversion with standard order coordination at its discretion during normal work hours.
Loop Provisioning Involving Integrated Digital Loop Carriers 2.6.1 Where InterGlobe has requested an Unbundled Loop and BellSouth uses IDLC systems to provide the local service to the End User and BellSouth has a suitable alternate facility available, BellSouth will make such alternative facilities available to InterGlobe. If a suitable alternative facility is not available, then to the extent it is technically feasible, BellSouth will implement one of the following alternative arrangements for InterGlobe (e.g. hairpinning):
Reverse ADSL Loops If a CLEC’s ADSL Transmission Unit (including those integrated into DSLAMs) is attached to Sprint’s Network and if an ADSL Copper Loop should start at an outside location, and is looped through a host or remote, and then to the subscriber, the copper plant from the outside location to the Sprint host or remote central office must be a facility dedicated to ADSL transmission only and not part of Sprint’s regular feeder or distribution plant.
Unbundled Sub-Loop Concentration System (USLC 2.9.1 Where facilities permit and where necessary to comply with an effective Commission order, BellSouth will provide <<customer_name>> with the ability to concentrate its sub-loops onto multiple DS1s back to the BellSouth Central Office. The DS1s will then be terminated into <<customer_name>>’s collocation space. TR-008 and TR303 interface standards are available.
Copper Subloops Sprint will make available access to copper subloops on an unbundled basis. A copper subloop is a portion of a Copper Loop, or Hybrid Loop, and is comprised entirely of copper wire or copper cable that acts as a transmission facility between any accessible terminal in Sprint’s outside plant, including inside wire owned or controlled by Sprint, and the end-user customer premises. A copper subloop can also include intermediate devices, such as repeaters, used to establish the transmission path. Copper subloops can be used by CLEC to provide voice-grade services as well as digital subscriber line services. Access to copper subloops is subject to the collocation provisions of this Agreement. Copper subloop consists of the distribution portion of the copper loop. Sprint is not obligated to offer feeder loop plant as a stand-alone UNE.
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.
