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.
Signaling Link Transport 9.2.1 Signaling Link Transport is a set of two or four dedicated 56 kbps transmission paths between Global Connection-designated Signaling Points of Interconnection that provide appropriate physical diversity.
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.
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.
wire Unbundled ISDN Digital Loops These will be provisioned according to industry standards for 2-Wire Basic Rate ISDN services and will come standard with a test point, OC, and a DLR. NewPhone will be responsible for providing BellSouth with a Service Profile Identifier (SPID) associated with a particular ISDN-capable Loop and customer. With the SPID, BellSouth will be able to adequately test the circuit and ensure that it properly supports ISDN service.
Wire Unbundled DS1 Digital Loop This is a designed 4-wire Loop that is provisioned according to industry standards for DS1 or Primary Rate ISDN services and will come standard with a test point, OC, and a DLR. A DS1 Loop may be provisioned over a variety of loop transmission technologies including copper, HDSL-based technology or fiber optic transport systems. It will include a 4-Wire DS1 Network Interface at the End User’s location.
-wire Unbundled Digital/DS0 Loop These are designed 4-wire Loops that may be configured as 64kbps, 56kbps, 19kbps, and other sub-rate speeds associated with digital data services and will come standard with a test point, OC, and a DLR.
Two-Way Interconnection Trunks 2.4.1 Where the Parties have agreed to use Two-Way Interconnection Trunks for the exchange of traffic between Verizon and VarTec, VarTec shall order from Verizon, and Verizon shall provide, the Two-Way Interconnection Trunks and the Entrance Facility, on which such Trunks will ride, and transport and multiplexing, in accordance with the rates, terms and conditions set forth in this Agreement and Verizon’s applicable Tariffs.
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 Sub-Loop Feeder (USLF) provides connectivity between BellSouth's central office and its cross-box (or other access point) that serves an end user location.
