Product Description

Loop MUX Combination (LMC) is a combination of an Unbundled Local Loop and a Digital Signal Level 1 (DS1) or Digital Signal Level 3 (DS3) multiplexed facility. The multiplexed facility is provided as an Interconnection Tie Pair (ITP) from the high side of the multiplexer to the Competitive Local Exchange Carrier's (CLEC's) collocation. Both the multiplexer and the collocation must be located in the same Qwest Wire Center. An Enhanced Extended Loop (EEL) Loop with transport can be connected to the LMC multiplexer facility.

Loop MUX Combination (LMC) provides you with the ability to access end-users and aggregate DS1 or Digital Signal Level 0 (DS0)- Analog Voice Grade (VG) loops to a higher bandwidth using a DS1 or a DS3 multiplexed facility. There is no transport between the multiplexer and your collocation. The LMC multiplexed facility must terminate in your collocation. An LMC loop must terminate at an end-user's premises/demarcation point.

Digital Signal Level 0 (DS0) - Analog Voice Grade is a two-point circuit that provides such services as:

• One Flat Rate Residential (1FR) or One Flat Rate Business (1FB) Plain Old Telephone Service (POTS), off-premises extensions, or off-premises station lines.
• Private Branch Exchange (PBX) trunks or trunk type tie lines
• Voice Grade Private Line

Product Diagram

The DS3 to DS1 LMC mulitplexed facility allows you to terminate 28 DS1 loops on the low side of the multiplexer and to multiplex them up to a single DS3, terminating on the high side of the multiplexer. An ITP is used to create a DS3 transmission path from the multiplexer to your collocation within the same Qwest Wire Center. The DS1 loop extends from your Connecting Facility Arrangement (CFA), e.g., DS3 multiplexed connection, to the end-user's premises/demarcation point. An EEL DS1 Loop with transport can be connected to this multiplexer.

The DS1 to DS0 LMC multiplexed facility allows you to terminate 24 DS0 loops on the low side of the multplexer and to multiplex them up to a single DS1, terminating on the high side of the multiplexer. An ITP is used to create a DS1 transmission path from the multiplexer to your collocation within the same Qwest Wire Center. The DS0 loop extends from your CFA, e.g., DS1 multiplexed connection, to the end-user's premises/demarcation point. An EEL DS0 Link/Loop with transport can be connected to this multiplexer.

Availability

Loop MUX Combination (LMC) is available where facilities exist throughout Qwest's 14-state local service territory.

Terms and Conditions

Pricing

Rate Structure
Recurring charges are comprised of the following rate elements:

• Unbundled Local Loop - DS0 or DS1 loop
• Channel Performance at DS0 Analog Voice Grade level
• Multiplexing - DS3 to DS1 or DS1 to DS0
• ITP

Recurring charges bill on a month-to-month basis. Term contracts and volume discounts are not available.

There are three different LMC nonrecurring charges. The one that is applied to your service request is dependent upon the work Qwest must perform to fulfill your request. The following provides a brief description of each LMC nonrecurring charge.

• Full installation nonrecurring charges are assessed when provisioning new LMC loops or Multiplexed LMC facilities.
• A conversion nonrecurring charge is assessed when converting an existing Private Line/Special Access circuit to LMC. This is a billing change only and referred to as a Conversion As Is. No physical work or redesign of the circuit is involved.
• A rearrangement nonrecurring charge may apply for some Conversion as Specified requests:
  • Roll an existing Private Line circuit from an existing Private Line Multiplexed facility to an existing LMC Multiplexed facility and convert the Private Line circuit to LMC.
  • Reterminate an existing Multiplexed Private Line circuit from one slot to another at the same CLEC’s collocation Alternate Point of Termination (APOT); and convert the Multiplexed Private Line circuit to a Multiplexed LMC facility.
  • Redesign an existing Point-to-Point Private Line circuit to ride an existing Multiplexed LMC facility and; convert the Private Line to an LMC Loop.
  • Redesign an unbundled local loop to ride a Multiplexed LMC facility.

Full LMC Installation Nonrecurring charges apply to the following Conversion As Specified requests:

• The conversion of an existing POTS service to LMC Loop
• An existing Multiplexed LMC migrating from one CLEC to another.

A rearrangement nonrecurring charge may be assessed on some requests for work to be performed by Qwest on an existing LMC:

• Move an LMC Loop from one slot to another on the same Multiplexed LMC.
• Reterminate a Multiplexed LMC facility from one slot to another at your collocation APOT.

For coordinated project installations scheduled to commence out of hours, or rescheduled by a CLEC to commence out of hours, additional nonrecurring charges will be applied to each LMC circuit for the work performed by Qwest outside of normal business hours. If this offering is not included in your current ICA, an amendment will be required. Out of Hours Project Coordinated Installations are offered only in those states that contain the appropriate rates found under Miscellaneous Charges in Section 9.20 of Exhibit A for the specific state.

Additional rate information can be located in Exhibit A or the specific rate sheet in your Interconnection Agreement. The nonrecurring charges, either full installation or rearrangement, applied to Conversion as Specified requests are dependent upon the physical work Qwest must perform. Full LMC installation nonrecurring charges will apply on all Conversion as Specified requests unless your current Interconnection Agreement includes the LMC rearrangement nonrecurring charge. If you wish to amend your current Interconnection Agreement to include either LMC or the rearrangement nonrecurring charge, contact your Qwest Service Manager.

For Private Line/Special Access Services that are converted to LMC, minimum service period, termination liability and shortfall charges for the product from which the circuit is being converted will apply and will be assessed as described in the individual state Tariffs/Catalogs/Price Lists. If you wish to convert services to LMC the conversion of these services will not be delayed due to the applicability of minimum service period, shortfall or termination liability charges.

Information regarding Geographic Deaveraging is available in Geographic Deaveraging - General Information.

Rates

Wholesale rates for this product or service, including tariff references and any applicable discounts, are provided in your current Interconnection, Resale, Commercial, or other governing agreement.

Tariffs, Regulations and Policies

Loop MUX Combinations (LMC) are provisioned where existing facilities are available and/or where you have CLEC Requested UNE Construction (CRUNEC) per the terms and conditions of your Interconnection Agreement.

When you submit your service request and facilities are not available, your request may be held for 90 business days. For exceptions and detailed information, refer to the Provisioning and Installation Overview.

Co-mingling is the Federal Communications Commission's (FCC's) term for "combining loops or loop-transport combinations with tariffed services." Combining tariffed services such as Private Line/Special Access or Switched Access Services with Unbundled Network Elements (UNEs) is prohibited. Circuits connected to a Qwest tariffed service will not be converted to or provisioned as an LMC.

Eligible circuits that are converted from Private Line/Special Access Service to LMC will retain all optional features and functions that were associated with the existing service as requested from the tariffs(s). After a circuit has been converted to LMC and you wish to make design changes to that service, the change requested must be in compliance with the design requirements identified in Technical Publication, Unbundled Network Element Combinations Including Enhanced Extended Loop (EEL) and Loop Mux Combination (LMC), 77403.

The Special Request (SR) process is used when you are requesting nonstandard combination of previously available UNEs, or certain UNEs that Qwest does not offer as a standard product but have been identified by the Federal Communications Commission (FCC) or State Commission as network elements. Special Requests information is described in Bona Fide Request (BFR) and Special Request (SR) Processes.

If the change is outside of the scope of Technical Publication, Unbundled Network Element Combinations Including Enhanced Extended Loop (EEL) and Loop Mux Combination (LMC), 77403 the Special Request Process must be followed.

Optional Features
There are no optional features available with LMC.

Features Ability to aggregate unbundled LMC and EEL loops at a multiplexer located in the same Qwest Wire Center as your collocation

Benefits Cost effective Eliminates the need for DS0 or DS1 terminations in your collocation

See Features/Benefits.

Product Prerequisites
If you are a new CLEC and are ready to do business with Qwest, view Getting Started as a Facility-Based CLEC. If you are an existing CLEC wishing to amend your Interconnection Agreement or New Customer Questionnaire, additional information is located in the Interconnection Agreement.

Before submitting your first request to either convert or provision new LMC service, you should review your Interconnection Agreement. If your Interconnection Agreement includes provisions for UNE combinations, all of the UNEs making up the LMC, and all of the appropriate recurring and nonrecurring billing elements comprised in an LMC, an amendment to your Interconnection Agreement is not required. The following LMC billing elements must be included your Interconnection Agreement:

• ITP for connection to your collocation – only recurring charges apply.
• DS0 and DS1 Unbundled Local Loops to provide the loop segment to your end-user. Recurring and nonrecurring charges apply. Your Interconnection Agreement must include the nonrecurring rate for Basic Installation with Cooperative Testing.
• DS1 to DS0 and DS3 to DS1 Multiplexing for the installation of Multiplexed LMCs. Both recurring and nonrecurring charges apply.
• Channel Performance for the installation of DS0 - Analog VG LMC circuits. Only recurring charges apply.

Without an LMC amendment, full nonrecurring charges for loop and multiplexing as described in the your Interconnection Agreement will apply when converting Private Line/Special Access circuits to LMC and when provisioning new LMCs.

If you are amending your Interconnection Agreement, a New Customer Questionnaire must be updated and provided to your Qwest Service Manager.

Before accepting an LMC conversion service request, Qwest will perform a pre-qualification process todetermine each circuit's eligibility to convert to LMC. The pre-qualification process is not an audit of local usage.

As part of the pre-qualification process you must complete the Pre-Qualification UNE-Combinations Spreadsheet Template, which identifies the circuits to be converted, and return it to your Qwest Service Manager. Spreadsheets that do not contain all of the required information will be rejected.

Once the Pre-Qualification UNE-Combinations Spreadsheet has been received, you will receive pre-qualification feedback based on the following intervals:

Number of Circuits	Response Interval
1 - 28	5 business days
29 - 60	6 business days
61 - 99	7 business days
100 or more	Negotiated with your Qwest Service Manager

If you have a limited number of circuits to pre-qualify for conversion and you want to negotiate an alternative qualification process, contact your Qwest Service Manager.

The pre-qualification process will validate the following:

• The circuit exists in Qwest billing records.

• The end-user name and address on the spreadsheet match Qwest billing records.

• The circuit terminates at an end-user premises.

• The multiplexed facility begins at your collocation and ends in a multiplexer in the same Qwest Wire Center.

• If the circuit is 'co-mingling' or connected to a Qwest tariffed service. Circuits will be evaluated for co-mingling up through the highest customer owned facility. Combining Private Line/Special Access or Switched Access Services with LMC is prohibited.

Upon completion of the pre-qualification process, Qwest will provide a validation code to you for circuits that qualify for conversion to LMC.
