Unbundled Copper Loops (UCL) 2.4.1 BellSouth shall make available Unbundled Copper Loops (UCLs). The UCL is a copper twisted pair Loop that is unencumbered by any intervening equipment (e.g., filters, load coils, range extenders, digital loop carrier, or repeaters) and is not intended to support any particular telecommunications service. The UCL will be offered in two types – Designed and Non-Designed.
Tandem Transit Traffic 12.1 As used in this Section, Tandem Transit Traffic is Telephone Exchange Service traffic that originates on CBB's network, and is transported through Verizon’s Tandem to the subtending End Office or its equivalent of another carrier (CLEC, ILEC other than Verizon, Commercial Mobile Radio Service (CMRS) carrier, or other LEC (“Other Carrier”). Neither the originating nor terminating customer is a Customer of Verizon. Subtending End Offices shall be determined in accordance with and as identified in the Local Exchange Routing Guide (LERG). Switched Exchange Access Service traffic is not Tandem Transit Traffic.
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.
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.
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):
FTTP Loop A Loop consisting entirely of fiber optic cable, whether dark or lit, that extends from the main distribution frame (or its equivalent) in an end user’s serving End Office to the demarcation point at the end user’s customer premises or to a serving area interface at which the fiber optic cable connects to copper or coaxial distribution facilities that extend to the end user's customer premises demarcation point, provided that all copper or coaxial distribution facilities extending from such serving area interface are not more than 500 feet from the demarcation point at the respective end users' customer premises; provided, however, that in the case of predominantly residential multiple dwelling units (MDUs), an FTTP Loop is a Loop consisting entirely of fiber optic cable, whether dark or lit, that extends from the main distribution frame (or its equivalent) in the End Office that serves the multiunit premises: (a) to or beyond the multiunit premises’ minimum point of entry (MPOE), as defined in 47 C.F.R. § 68.105; or
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).
Integrated Digital Loop Carriers The feeder portion of some loops may be provide by means of Integrated Digital Loop Carrier (IDLC). IDLC provides a fiber optic cable transmission path that travels directly into BellSouth’s central office local switch. Where BellSouth uses IDLC ,if technically feasible and capacity does exist, BST will provide Al-Call with a Designed DS0 UVL by using alternative provisioning techniques including but not limited to such as “hairpinning” and DAC grooming. Alternative provisioning techniques will be provided at no additional cost to Al-Call . Hairpinning involves providing a DS0 signal from an IDLC-served loop to Al-Call ’s collocation equipment by using a dedicated pathway that traverses BellSouth’s central office switch. BellSouth will provide such DS0 signal to Al-Call by establishing a copper cross connect between the BellSouth switch and Al-Call ’s collocation equipment.
-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.
