Qwest Local Services Platform® (QLSP®) - Centrex - V2.0

History Log

Product Description

Qwest Local Services Platform® (QLSP®) products provide local exchange telecommunications services to end-users on behalf of Competitive Local Exchange Carriers (CLECs) at competitive wholesale commercial rates. General information about QLSP can be found in Qwest Local Services Platform (QLSP) - General Information.

QLSP Centrex 21, QLSP Centrex Plus, and QLSP Centron provide exchange services between your end-user's premises and the Qwest Central Office (CO) that are functionally equivalent to Qwest's retail Centrex service offerings. QLSP products are finished services requiring neither CLEC collocation nor other CLEC network involvement, and are combinations of the following network elements:

• A 2-Wire Analog (Voice Grade) Unbundled Local Loop
• An Analog Line Side Port, including Local Switch Usage and any optional switch features(Local Switching Network Element)
• Shared Transport
• Network Access Registers (NARs) on QLSP Centrex Plus and QLSP Centron

QLSP Centrex 21 is a business service providing access to 21 different standard and optional features and is intended for end-users with 2 to 50 station lines per location. Standard features are available to all station lines in the shared customer group.

A common block is a dedicated space in the CO that is provisioned to contain certain specified standard features that are available for all station lines. QLSP Centrex 21 provides a pre-provisioned common block containing specified standard features that are available for all station lines. The standard feature package and optional feature availability may vary from state to state. For all packages, plans and features view the Tariffs/Catalogs/Price Lists.

QLSP Centrex Plus and QLSP Centron services are central office based business communications services with state-of-the-art capabilities and features provisioned by the use of local network transport technologies. A group of station lines is translated for an individual customer group and provides common access to a predetermined group of system features. All station lines in the system have intra-system calling capability. A choice of access to the local exchange calling area via each station line (non-blocked) or controlled access line (blocked) depends upon the number of subscribed NARs. Touchtone, Automatic Identified Outward Dialing, Direct Inward Dialing (DID®), and Individual Line Billing are inherent with the service and are automatically programmed within the station line.

Availability

QLSP products are available where facilities exist throughout Qwest's 14-state local service territory.

QLSP Centrex Plus and QLSP Centron are available depending on the facilities and generic feature programs in the central office switches. Centrex Plus is grandfathered and not available for new installations in some states. Centron is grandfathered and is available for new installations only in Minnesota. To determine state availability refer to the state specific Tariffs/Catalogs/Price Lists.

Although Retail and Resale Centrex 21 services are grandfathered effective 04-11-05, QLSP Centrex 21 remains available in accordance with terms and conditions, and rates provided in your Commercial Agreement.

QLSP Centrex 21 is available from suitably equipped digital COs only and is offered subject to availability of facilities and applicable generic feature programs.

Terms and Conditions

Line Splitting is available with QLSP Centrex. Information is available in Line Splitting.

The minimum requirement for Centrex 21 service in all Qwest states is two (2) lines. A partial conversion of existing Retail or Resale Centrex 21 service to QLSP Centrex 21, or a move/change of existing QLSP Centrex 21 may cause the service to fall below this two line minimum requirement. When you submit a Local Service Request (LSR) that results in a Centrex 21 service falling below the two- line minimum, you must mark the request for manual handling and provide instructions in the REMARKS field regarding the remaining service, including alternative service type, desired features, etc. If instructions are not provided, Qwest will convert the remaining line to the current platform POTS service with no features. If Qwest broadband is present on the remaining line, it will be retained.

QLSP Centrex 21 is pre-provisioned with Assumed Dial 9 in the common block (which means all outgoing calls are dialed directly on the switched network, not within the common block). Therefore, 4-digit dialing to another Centrex 21 station and dialing plans of less than 7 digits is not possible.

All QLSP Centrex Plus and QLSP Centron station lines must be associated with the main switching equipment. The Centrex or Centron system may be either blocked or non-blocked, however they cannot be mixed. Combined station lines terminating at different locations into a single system must be served by the same CO.

Telephone numbers (TNs) for Centrex Plus must be ordered in blocks, either through your Service Manager or via a request to the Interconnect Service Center. TNs for Centrex Plus may not be reserved through IMA.

Implementation

Product Prerequisites

If you are a new CLEC and are ready to do business with Qwest, view Getting Started as a Facility-Based CLEC and Interconnection Agreement, and Commercial Agreements.

If you are an existing CLEC would like to amend your Interconnection Agreement or New Customer Questionnaire, refer to Interconnection Agreement Amendments. To review and/or request preparation of a QLSP Agreement, visit Commercial Agreements.

Pre-Ordering

General pre-ordering activities are described in the Pre-Ordering Overview.

Requirements for pre-ordering are described in Local Service Ordering Guidelines (LSOG) Pre-Order.

To request new QLSP Centrex Plus or QLSP Centron service, contact your Qwest Service Manager for assistance with identifying functionality requirements and to request a common block built in the switch where you want to provide service. Before ordering any optional, standard, or system features, you must verify if the feature is built into the common block. Features that are not built into the common block may be requested through your Qwest Service Manager.

Notify your Qwest Service Manager if you would like to convert your resale or retail Centrex to QLSP Centrex prior to submitting your request.

Ordering

It is important to review and understand the ordering procedures described in Qwest Local Services Platform (QLSP) - General Information.

General ordering activities are described in the Ordering Overview.

Disclosure Information and other Local Service Ordering Guidelines (LSOG) are available in Network Disclosures.

Intervals for conversions from retail or resale Centrex to QLSP Centrex of 50 or more stations will be handled on an Individual Case Basis (ICB). Once a due date is assigned Qwest will establish a moratorium on other account activity during the conversion.

Requests for QLSP Centrex are placed using the Interconnection Mediated Access (IMA) Graphic User Interface (GUI) or IMA Extensible Markup Language (XML). You may also submit the completed LSOG forms to Qwest by facsimile to (888) 796-9089. Detailed information regarding field entry requirements are described in the LSOG.

The following LSOG forms may be required:

• LSR
• End User (EU)
• Centrex Resale Service (CRS)
• Directory Listing (DL)

When requesting a full conversion to QLSP Centrex 21 service from other existing, e.g. Resale, Centrex 21 service, using the LSR ACT Type = V, all listings on the current account must be addressed using applicable LACT values or the listing will be rejected. If there are no change(s) to the listing(s), the listing(s) should have the LACT value of Z. If the LSR ACT Type = V, and a LACT value of Z is present on the DL form, the TN will be used for validation purposes, but all other information on the DL form will be ignored. The listing will remain exactly as it exists on Qwest's Customer Service Record. If any change(s) are made to a listing(s), then LACT O, I, or D values should be entered. LSRs with 'LACT = N - New Listing' selected when changes are being made to existing listings will be manually rejected by Qwest. Only new listings may be added with LACT = N during conversion activity. Existing listings may be deleted during conversion activity with LACT = D - Delete Listing.

In addition, if any change(s) are made to any existing listing(s) using LSR ACT = C, T or R, then LACT = O, I or D values should be entered.

When converting an existing account with Qwest Broadband to QLSP Centrex, follow the requirements in the Ordering section of Qwest Commercial Broadband Service.

QLSP Centrex 21 end-users share a common block within the CO. As a result, all end-users share the functionality of the common block. The common block name must be provided in the Common Block (CB) field on the CRS.

Generic QLSP Centrex 21 common block names by switch type:

Switch Type	Common Block Name
5ESS®	IDP2100
DMS-10	21
DMS-100	CTX2100:0
Ericsson	2100

Some DMS-100 Remote switches may carry a different Common Block name than is shown above. If you have any questions as to whether or not the standard Common Block name for the CO is applicable, contact your Qwest Service Manager.

A Line Class Code (LCC) identifies the originating and terminating calling restrictions or combinations of calling restrictions for a line and is stored in the common block memory of the program controlled switch. The LCC must be entered in the FEATURE DETAIL field on the CRS form.

To verify whether or not to use the BLOCK field or assign a specific LCC on the CRS form, see the Blocking Job Aid.

For additional information on Centrex LCCs, refer to the Centrex Line Class Code (LCC) Job Aid. The tables in this job aid are provided for informational purposes only and are a sampling of the most commonly used LCCs for each of the Centrex products. The appearance of an LCC in one of the tables does not mean that it is available to be assigned to your Centrex accounts. If you have any questions regarding the availability of a particular LCC, please contact your Qwest Service Manager.

A Customer Access Treatment (CAT) Field Identifier (FID) is assigned for each station line in a common block and allows a station line to access system features using dial access codes. The CAT FID must be entered in the Line Treatment Code (LTC) field for each station line on the CRS.

In all switch types other than the DMS-100, there is only one CAT FID assigned to the switch at the account level. The CAT works in conjunction with the individual LCC for the type of calling restriction requested.

In the DMS-100, different CAT FIDs can be assigned at the line level rather than at the account level. The calling restriction type is derived from the combination of the CAT and LCC. The CAT FID identifies the calling restrictions for outgoing calls and the LCC identifies the incoming calling restrictions.

DMS-100 CAT FIDs and corresponding LCC:

CAT FID	Description of CAT*	Corresponding LCC
0	Non-restricted: No restrictions are placed on the line, the end-user can make and receive all calls.	NCN
2	Long distance restricted: The end-user can place outgoing local calls, including DA 411, they cannot dial any 1+ or 0+ calls and can receive all incoming calls.	NCT
4	Non-restricted (Block 900/976): The end-user can make all local and long distance calls with the exception of 900/976 calls and can receive all incoming calls.	NC9
6	Restrict DA (411 & 1+555): The end-user can make all local and long distance calls with the exception of DA 411 and 1+555. They can receive all incoming calls.	C3R
7	Toll restricted Deny DA: the end-user can place outgoing local calls, they cannot dial any 1+ or 0+ calls, or calls to DA 411 or 1+555. They can receive all incoming calls.	NCB
8	Restrict DA (411 & 1+555) and (Block 900/976): The end-user can make all local calls with the exception of DA 411. They can make all long distance calls except 1+555 and 900/976 and can receive all incoming calls.	D3R

* If the calling restrictions you are interested in are not shown above, contact your Qwest Service Manager for assistance.
