Unbundled Subloops

Overview

What It Is

Verizon's Unbundled Subloop Arrangements give CLECs access to our metallic copper distribution pairs and facilities. With this type of arrangement, you can provide customer voice grade service and data service via ISDN, ADSL, HDSL, DDL, IDSL, DDS and SDSL.

How It Works

Unbundled subloops offer a 2- or 4-wire transmission channel between the Telecommunications Carrier Outside Plant Interconnection Cabinet (TOPIC) and the Network Interface Device (NID) and/or rate demarcation point at the end user location. This channel interconnects from Verizon's feeder distribution interface.

Description

Unbundled Sub-Loop Arrangement (USLA) provides a CLEC access to Verizon's metallic distribution pairs/facilities at the Verizon Feeder Distribution Interface (FDI). USLA provides either a 2-wire or 4-wire transmission channel between the CLEC's Telecommunications Outside Plant Interconnection Cabinet (TOPIC), located at an FDI, and the Rate Demarcation Point or the Network Interface Device (NID), if the NID is located at the Rate Demarcation Point at the End User's premise.

Availability

Unbundled Subloop Arrangement (USLA) is available throughout the Verizon footprint.

Features

Spectrum Management - CLEC's will be allowed to provision DSL services utilizing Unbundled Subloop Arrangement (USLA) to the extent that the use of the technologies comply with all Verizon standards and do not impair service to other subscribers within Verizon's outside plant facilities. Standards associated with interference and non-conformance will be developed through national standards organization such as T1E1.

Detailed Information

Under an Unbundled Subloop Arrrangement (USLA), an existing sub-loop may be used by a CLEC to provide service to an end user's location. The service can entail either conversion of service using an existing working sub-loop or the establishment of original service re-using an existing spare sub-loop. Distribution pairs currently in place to serve Verizon Retail POTS service can be converted to USLA; no new distribution facilities will be installed for this product. All distribution loops are assumed to meet normal CSA requirements.

Power is not provided with USLA.

Responsibility of the requesting CLEC

The requesting CLEC will be responsible for the following:

• Obtaining any necessary rights of way from the local authority
• Necessary power
• Any fines, penalties and expenses for zoning, environmental, safety, sanitation, property infringement, noise, quality of life or property violations or law suits associated with the Telecommunications Outside Plant Interconnection Cabinet (TOPIC), its supporting structure and associated power and any additional tax assessment levied on Verizon as a result of the supporting structure.
• Providing and installing the TOPIC within 100 feet of the FDI on an easement or right of way obtained by the requesting CLEC. The TOPIC will comply with industry standards and house the interconnection point between Verizon and the requesting CLEC's networks.
• When the CLEC is not collocated at the RTEE (Remote Terminal Equipment Enclosure), the CLEC must place its cross-connect panel or similar structure within 100 feet of the FDI on an easement or right of way obtained by the CLEC. The equipment used by the CLEC must comply with industry standards and house the interconnection point between the Verizon and CLEC's networks.
• Providing any trenching or other supporting structure for the portion of the interconnect cable that runs beyond Verizon's easement at the FDI.
• Provide and terminate its facilities on a block within the TOPIC cabinet.
• The CLEC, at its option, may share the TOPIC with other CLECs.
• Request the cross connection of Verizon's distribution sub-loop elements from Verizon.
• Sub-loop provisioning may occur either as a conversion on Verizon Retail POTS service or as a new sub-loop installation to the end-user.
• The use of a standardized block type that will support a quality operating environment within the cross connect and allow for the use of standard testing devices to facilitate testing and reporting procedures.
• Running the cross wires within the TOPIC. The CLEC will have assignment responsibilities for the pairs in the interconnect cable.

Responsibility of Verizon

Verizon will be responsible for the following:

• Furnishing and placing the interconnect cable between the Verizon FDI and the TOPIC.
• Installing the termination block within the TOPIC.
• Verizon's service responsibility ends at Verizon's side of the CLEC's cross-connect panel.
• Maintenance responsibility for the service from the Verizon side of the termination block at the TOPIC to the termination of the Sub-loop segment at the end-user location.
