Line Splitting

Overview

Ever considered partnering with another CLEC to expand your service offerings?

Verizon's Line Splitting service enables your company to offer customers integrated voice and data service over an unbundled voice service subscriber loop.

Data uses the higher frequency ranges and voice the lower frequencies of the same line to split the technology into a shared line. Each CLEC provider merely employs different analog frequencies for transporting voice and data on the line.

How It Works

One splitter is installed at the end user premises and a second one at the central office. The splitters permit xDSL service to be added to the local loop so that Line Splitting can be provisioned.

In order to provision Line Splitting, the voice CLEC needs a Wholesale Advantage arrangement or the data CLEC a line sharing agreement in the central office where the line is to be split. End users must be active customers of the serving switch provider.

Description

Local Service Providers (LSPs) may provide integrated voice and data services over the same Loop by engaging in “Line Splitting” as set forth in paragraph 18 of the FCC's Line Sharing Reconsideration Order (CC Docket Nos. 98-147, 96-98), released January 19, 2001. Any Line Splitting between two LSPs shall be accomplished by prior negotiated arrangement between those LSPs.

The participating LSPs shall provide any splitters used in a Line Splitting configuration. LSPs seeking to migrate existing Wholesale Advantage configurations to a Line Splitting configuration using the same Network Elements utilized in the pre-existing platform arrangement, or seeking to migrate a Line Sharing arrangement to a Line Splitting configuration using the existing Loop, a Verizon Local Switching Network Element, and the existing central office wiring configuration, or seeking to establish a new Wholesale Advantage with a data element, may do so consistent with such implementation schedules, terms, conditions and guidelines as are agreed upon for such migrations in the ongoing DSL Collaborative in the State of New York, NY PSC Case 00-C-0127, allowing for local jurisdictional and OSS differences.

Availability

Line Splitting is available throughout the Verizon Footprint.

Pricing

Except as noted in the next paragraph, the Local Service Provider (LSP) in a Line Splitting arrangement will be billed for all charges associated with the Network Elements and other Verizon services, facilities and arrangements, used in conjunction with the Line Splitting arrangement, regardless of which LSP orders the Network Elements or other Verizon services, facilities or arrangements. These charges include, but are not limited to, any line related charges, such as line conditioning charges and misdirected trouble charges.

The LSP with the applicable collocation arrangement will be billed for splitter establishment and collocation related charges.

Non-recurring Costs (NRC)

Charges will apply as applicable for the type of order submitted.

Initial Service Order, Order processing - one time charge is applied on a per LSR basis for the initial Line Splitting request.

Subsequent Service Order, Order processing - one time order processing charge for subsequent changes to the existing Line Splitting arrangement.

Initial Service Order, Provisioning (first unit or additional unit) - one time provisioning charge for the initial or additional lines on a new Line Splitting request.

Subsequent Service Order, CO Connect, Provisioning (first unit or additional unit) - one time provisioning charge for the initial or additional lines on a change to an existing Line Splitting arrangement.

Line Conditioning – is applied on a per occurrence basis, when requested by the Voice LSP or Data LSP, and is for the removal of load coils, filters and/or bridge tap. It is the VLSP/DLSP's responsibility to request on the LSR the type of Line Conditioning that is needed.

Monthly Recurring Costs (MRC)

Line Split Loop; charge for the xDSL capable loop associated with the Line Splitting arrangement.

Line Split Port & Usage Elements; charge for the line split port and usage associated with the Line Splitting arrangement.

See your federal and state tariffs for detailed information.

Features

Line Splitting will be provided in two basic configurations, consistent with existing Line Sharing rules as follows:

• Local Service Provider (LSP) Owned Splitter – Virtual – The LSP will purchase the splitter, then sell it to Verizon at a nominal charge for installation in the Central Office.
• LSP Owned Splitter - Physical – The LSP will own and install the splitter in its collocation area.

Orders for LSP owned splitter configurations require block and pin information for cross connects to designate the splitter assignment.

Detailed Information

Local Service Providers (LSPs) must comply with the following:

• The Voice LSP must update its profile (or submit a Carrier Profile) to declare its joint use arrangement with the Data LSP.
• The Voice LSP must provide circuit-switched voice grade service to the customer using a Verizon Local Switching Network Element. The customer's dial tone must originate from a Verizon end office switch in the Verizon wire center where the Line Splitting arrangement is established.
• The LSPs must access the Loop in a Line Splitting arrangement through a collocation arrangement at the Verizon wire center that contains the end office switch through which voice grade service is provided to the customer.
• The Voice LSP or Data LSP must have a LSP provided splitter in the physical or virtual collocation area to which the Line Splitting arrangement will be provisioned. The LSPs must also provide any necessary DSLAM equipment and CPE.
• The loop must consist of a copper loop compatible with an xDSL service that is presumed to be acceptable for shared-line and Line Splitting deployment in accordance with FCC rules. Loop pre-qualification should be performed to determine loop qualification, consistent with UNE Loop and Line Sharing rules.
• Use of the Loop must comply with applicable FCC technical standards, including, but not limited to, FCC standards with regard to interference with other services.
• The LSPs must provide Verizon with information concerning the xDSL technology that will be deployed on the Loop in accordance with applicable FCC rules.
• Line Splitting cannot be provisioned on primary hunt group numbers or roll over numbers.

Interconnection Agreement Provisions and Joint Use Declaration

Appropriate Line Splitting provisions must be included in both the Voice LSP's and Data LSP's interconnection agreements with Verizon before Line Splitting can be ordered. Contact your Verizon Account Manager or Verizon Contract Negotiations representative to add the appropriate interconnection agreement provisions.

The Voice LSP must provide Verizon notification of the VLSP/DLSP joint use arrangement for a given state, at least 30 days prior to placing an order for a Line Splitting arrangement for that state. This joint use declaration will be accomplished by updating the Carrier Profile.

Miscellaneous Information

End User Premise – The LSPs shall provide any micro filters or similar equipment needed at the end user premise to maintain the end user's analog equipment functionality.

End users with Alarm Services

xDSL technologies that share the Loop, such as ADSL, may cause interference with some monitored alarm systems, resulting in false alarms, or in some instances, impair the alarm system to the point that it becomes inoperative.

The VLSP is responsible for determining if the end user has an alarm system and for ensuring that the alarm system remains operative and is not interfered with by the high frequencies associated with Line Splitting related services. Verizon is not liable for any damages that may result if a Line Splitting related service interferes with the end user's alarm services.

Possible corrective measures include:

• If the alarm system interfaces with the inside wiring of the customer premise via an RJ11 jack, place a micro-filter between the alarm dial-up unit and the inside wiring.
• If the alarm system is 'hard-wired' to the inside wiring at the customer premise, install a splitter to isolate the high frequency data signals from the alarm dial-up unit.
