Description
Local Number Portability (LNP) is a procedure which addresses the interactions between Qwest and you in association with wireline to wireline. It also addresses the call processing impacts for other telecommunications providers in an LNP environment. Wireline to wireless is available, for detail information is described in the Wireless Local Number Portability (LNP).
Local Number Portability (LNP) is defined by the Telecommunications Act of 1996 as: "the ability of users of telecommunications services to retain, at the same location, existing telecommunications numbers, without impairment of quality, reliability, or convenience when switching from one telecommunications carrier to another."
Local Number Portability (LNP) is also referred to as Service Provider Portability, because LNP enables end-users to retain the same Telephone Numbers (TNs) when the end-users change from one local service provider to another within a rate center. The North American Numbering Council (NANC) recommended industry standards to the Federal Communications Commission (FCC) which adopted a further definition of Service Provider Portability allowing end-users to move within a Qwest® Rate Center and retain their TN. Service Provider Portability differs from Location Portability,
which is the ability to keep the same TN when moving to a
new location outside the Qwest Rate Center. It also differs
from Service Portability, which is the ability to keep the
same TN when subscribing to new services, e.g., from Plain
Old Telephone Service (POTS) to Integrated Services Digital
Network (ISDN). Neither Location Portability nor Service Portability
have been defined or deployed within the industry. LNP does sometimes allow end-users to subscribe to new services
when they move from one local service provider to another
or when their service is moved from one switch to another.
LNP also allows geographic portability within a Qwest Rate
Center. LNP fundamentally changes call processing in the public switched
network and has been deployed in compliance with FCC and industry
guidelines. LNP impacts all telecommunications providers,
including Interexchange Carriers (IXCs) and wireless carriers
as well as wireline local service providers.
Other processes in the LNP family are:
Port In is defined as the ability of End-Users to retain the same telephone number(s) when changing from one local service provider to another within a Rate Center. Either a new or existing Qwest end-user customer has requested that TN(s) currently provided by a different Network Service Provider to be ported into the Qwest network. These TN(s) may be established as POTS, Direct Inward Dial (DID), TNs with trunks or other types of services. Detailed information is described in the Port In PCAT
Port Within is defined as the ability of End-Users to retain the same telephone number(s) when moving from one service location to another (i.e., T&F), within a Rate Center. Port Within can also be noted as moving TNs from one switch to another, within the same Central Office, this is often done when moving DID TN(s) from one trunk group to another, when they have been established on different switches. This process may also include a conversion and a move via a single order request, with number port to a new address outside the existing switch, but within the same Rate Center. Detailed information is described in Port Within.
Background
Congress recognized the inability of end-users to retain their
TNs when changing local service providers, a circumstance
that would hamper the development of local competition. To
address this concern, the U. S. Congress added Section 251
(b)(2) to the Telecommunications Act of 1996 that requires
all Local Exchange Carriers (LECs) to provide, to the extent
technically feasible, LNP.
Simple Port Request (SPR)
On November 8, 2007 the FCC expanded LNP to VoIP and in the Order, FCC 07-188, they further defined LNP to include SPR.
A SPR is defined by the FCC in that order in footnote 153 as those Ports that:
- Involve a Single Line Account only
- Do not involve Unbundled Network Elements - (no Loop with Number Port);
- Do not include complex switch translations such as Centrex, DID Numbers, or Advanced Intelligent Network (AIN) service
- Do not include Remote Call Forwarding numbers (for Qwest this includes Market Expansion Line (MEL) Service).
- Do not include multiple services on the Loop such as Broadband, or other Data services
- Do not include a line that has been Resold (RSID or ZCID)
The FCC's order established that a maximum of four fields can be used for validation. The fields that may be required for End User Validation are:
- Customer Account Number (includes 10 digit telephone number plus CUS Code as assigned by Qwest)
- Zip Code (not applicable (NA) for Qwest)
- Telephone Number to be Ported
- Pass Code (NA for Qwest)
Local Number Portability (LNP) Network Architecture Overview
The industry solution for long-term number portability is a Location Routing Number (LRN) architecture. Under the LRN architecture, each switch is assigned a unique 10-digit LRN that identifies the location of that switch. The first 6-digits identify an NPA and NXX code that is assigned to that switch and the last 4-digits are in line number format. It is important to note that the LRN is not a TN; it is merely the identifier of the switch to which a TN is ported. The NPA and NXX identifies a particular switch, the 4-digit line number may be assigned as a working TN in that switch.
Each ported end-user's TN is matched in a regional Number
Portability Administration Center (NPAC) database with the
LRN for the switch that currently serves that TN. If the TN
is not ported, the TN does not appear in the Local Service
Management System (LSMS) number portability database and the
call is routed to the switch that was originally assigned
the NPA-NXX.
In a LNP environment, it can no longer be assumed that the
NPA-NXX code holder actually serves the end-user. During call
setup, an LNP database in the Signaling System 7 (SS7) network
is queried to determine which switch actually serves the dialed
TN. If the TN is ported, the Called Party Number (CdPN) field
is moved into the Generic Address Parameter (GAP) field, and
the LRN information is overlaid in the CdPN field so the call
can be routed to the proper terminating switch. The terminating
switch then completes the call to the end-user based on the
data contained in the GAP.
Location Routing Number (LRN) Assignment
To assign a LRN, you must obtain an NPA-NXX from the North American Numbering Plan Administrator (NANPA) for each LNP capable switch.
The industry LRN Assignment Practices were developed by the
Industry Numbering Committee (INC) and issued by the Alliance
for Telecommunications Industry Solutions (ATIS) on July 13,
1998 and Technical Requirements No. 2 prepared April, 1999
by the T1S1.6 Working Group on Number Portability and issued
by ATIS.
Specifically, the INC practice states that an NXX will not
be assigned to a service provider for the sole purpose of
establishing an LRN unless that service provider's switch
or Point of Interconnection (POI) does not yet have an LRN
for the Local Access Transport Area (LATA) where they intend
to provide service". The T1S1.6 technical requirement state:
"only one NPA-NXX is needed for the first 6-digits of an LRN
per LATA to identify the switch".
Qwest had previously recommended an LRN be assigned for each Qwest Rate Center that you intend to serve. All carriers, including Qwest, have concerns regarding TN conservation and in some cases assignment of new NPA-NXXs at a Qwest Rate Center level may not be necessary. To ensure conservation of numbering resources, and to comply with the INC practice, Qwest allows the ability to use one LRN to serve multiple Qwest Rate Center locations.
If you have already established a LRN for a particular Qwest Rate Center, you may continue to use that established LRN. If you do not need NPA-NXX codes that were assigned at a Qwest Rate Center level, you may notify Qwest to change from the LRN(s) assigned at a per Qwest Rate Center level to LRN(s) assigned at a per switch, per LATA level or for some lesser geographic area. Qwest will make appropriate network rearrangements to accommodate such change(s).You may return the unused NPA-NXX codes to the number administrator.
In those instances where you have not requested and have
no need for an NPA-NXX for a particular Qwest Rate Center,
you may notify Qwest of your desire to establish an LRN per
LATA, or for some lesser geographic area. This notification
must occur as soon as reasonably possible, but no later than
at the time you first arrange for your POI, Local Interconnection
Service (LIS) trunking, etc.
Single LRN/Alternate Routing for Location Routing Number (ARLRN)
General ARLRN activities are describes in Alternate Routing for Location Routing Number (ARLRN).
Local Number Portability (LNP) Query Services
Qwest provides Default Query
Services whenever we receive unqueried calls from other
telecommunications providers, including CLECs, Incumbent Local
Exchange Carriers (ILECs), IXCs, or Wireless Service Providers
(WSPs), which require a query in order to be terminated efficiently.
Qwest also offers Direct Query access to the LNP database.
NPA/NXX Migration or Reassignment
When you plan to provide service for all assigned TNs in a particular NPA/NXX, you should request reassignment of that NPA/NXX in the Local Exchange Routing Guide (LERG) in lieu of porting. In this situation NPA/NXX migration supports network efficiency and is the preferred industry method. To rearrange for a migration of entirer NPA/NXX, contact your Qwest Service Manager.
Local Number Portability (LNP) Administration
There are seven regional databases that serve specific geographic
areas. The Western Region database serves Qwest's 14-state
local service area plus Alaska. A neutral third party, called
the Local Number Portability Administrator (LNPA) administers
these regional databases.
The FCC adopted the NANC recommendation that the administrative
functions of the LNPA include all management tasks required
to develop and administer the regional databases, called Number
Portability Administration Centers (NPACs).
Number Portability Administration Centers (NPACs) responsibilities include:
- Management tasks required to run the NPAC
- Works with the users to update data tables required to route calls for ported local numbers or required for administration
- Responsible for NPAC SMS log on administration, user access, data security, user notifications, and management and is the primary contact for users who encounter problems with NPAC system features
- Provide the users with a central point of contact for reporting and resolution of NPAC problems
- Provide coordination/resolution of problems associated with system availability, communications and related capabilities
- Provide reports to regulatory bodies as required
Number Portability Administration Centers (NPACs) standard hours of business for LNP are 7:00 AM to 7:00 PM (CST / CDT), Monday through Friday. NPAC personnel are available outside of the LNP hours of operation on a pager/call-out basis.
North American Numbering Council information is described in the North American Numbering Council web page.
Managed Cuts
Managed Cuts are available for LNP in the following arrangements:
- Qwest Initiated Managed Cut
- CLEC Initiated Managed Cut
- LNP Coordinated Cut with Unbundled Loop
When a Qwest Initiated Managed Cut or CLEC Initiated Managed
Cut is requested, Qwest will initiate a telephone call and/or
arrange a meeting with you to discuss detailed information
regarding the Managed Cut.
Qwest Initiated Managed Cut
Qwest will initiate a Managed Cut when the 10-digit unconditional trigger or Line Side Attribute (LSA) cannot be set or when the port request for an account exceeds 2000 TNs or 200 trunks. Qwest Initiated Managed Cuts are scheduled within the normal business hours, at no additional charge. If you request a Frame Due Time (FDT) that is outside the normal business hours, the terms, conditions and prices of the LNP Managed Cut offering will apply.
CLEC Initiated Managed Cut
A CLEC Initiated Managed Cut is available under the "LNP Managed
Cut offering. If the LNP Managed Cut offering is not included
in your Interconnection Agreement, contact your Qwest Service
Manager to request a LNP Managed Cut amendment.
This offering allows you the ability to request coordination of a cut for LNP with a CLEC-provided loop (i.e., standalone LNP). LNP Managed Cuts are offered on a 24x7 basis. You may request any FDT when the mechanized 10-digit unconditional trigger can be set for the TNs being ported. If you request a coordinated cut for LNP with a CLEC-provided loop, even though the mechanized 10-digit unconditional trigger can be set, and/or if you request a coordinated cut outside normal business hours, the terms, conditions and prices of Qwest's LNP Managed Cut product offering will apply.
Local Number Portability (LNP) Coordinated Cut with Unbundled Loop
A LNP Coordinated Cut with Unbundled Loop is available if
you request to have your LNP cut coordinated with Qwest's
Unbundled Loop product. LNP
Coordinated Cuts with Unbundled Loop will follow the Unbundled
Loop process and charges associated with the Unbundled Loop
product will apply.
Availability
The FCC addressed specific requirements for providing number
portability on an interim basis, known as Interim
Number Portability (INP) as well as development and deployment
of the long-term solution known as LNP. Qwest has deployed
LNP in nearly every end office.
To determine LNP availability for Qwest wireline switches, refer to Network
Disclosure #414.
Qwest has offered INP since 1996 utilizing Remote Call Forwarding
(RCF), Direct Inward Dialing (DID®) service and Directory Number
Route Indexing. INP is only offered in those few locations
where LNP is not deployed. You may continue to request INP
in a non-LNP capable switch.
If you want LNP capability in a switch where Qwest has not deployed LNP, submit a LNP Bona Fide Request (BFR) letter to Qwest at any time, at no charge. The LNP BFR process is separate from the BFR process for interconnect services.
Any certified CLEC or WSP with an approved Interconnection Agreement
may submit a LNP BFR letter to request LNP capability in
a switch where LNP has not yet been deployed. The request
must include the 11-digit CLLI code of each Qwest switch being
requested to become LNP capable.
The following outlines what will take place upon Qwest's
receipt of the LNP BFR letter:
- Confirm received letter within 10 business days
- Deployment dates communicated no later than 45 calendar
days
- The timeline for conversion is within 180 days
- Qwest switches selected through the LNP BFR process will
be posted on the network disclosure web site
Contact your Qwest Service Manager to submit a LNP BFR letter.
Terms and Conditions
If terms and conditions for LNP are included in your Interconnection
Agreement, and those terms differ from those set forth in
this PCAT, then the terms of the Interconnection Agreement
will prevail.
Service Restrictions
Local Number Portability (LNP) Triggers are not expected to be placed on Service Codes or Service Access Codes (911, 411, 800, 866, 877, 888, 900, 500) so queries will not be performed on these call types. In addition, queries will not be performed in the originating switch for 0+, 0-, or 1+ calls routed to an IXC.
The following service restrictions apply:
- Telephone numbers may be ported only within their assigned
rate center.
Local number portability (LNP) is confined to Service Provider
Portability, either within the area serviced by the same
central office or between areas serviced by different central
offices within the same rate center.
- Across an NPA boundary
- 555, 960 and 976 NXXs
- 500, 700, 800, 866, 877, 888, 900, 911 services
- Other N11 codes e.g., 411, 511 etc.
- Qwest Public Coin or Semi-Public Coin
- Numbers used for mass calling events - Refer to North
American Numbering Council (NANC). Once displayed, click
on "LNPA Working Group then select "Documents". When this
page is displayed, click on "High Volume Call in Networks
Report, 5/7/98".
- Reserved Numbers
- Qwest's policy regarding the porting of reserved TNs
is to allow porting if the reserved numbers are identified
on the end-user service record.
- Porting service requests will not be taken on unassigned,
previously owned, disconnected, disconnected following
suspension for non-payment, or vacant TNs.
- Numbers associated with Paging Services.

Technical characteristics are described in Technical Publication, Qwest Common Channel Signaling (CCS) Network Interface Specification, 77342.

Pricing
Rate Structure
Rate structure information can be found in tyour Interconnection Agreement.
Charges for the LNP Managed Cut Offering
LNP Managed Cut Rates are available in your Interconnection Agreement. The charges you will incur for the LNP Managed Cut are dependent upon the FDT. The rates are based upon whether the request
is within or outside Qwest's normal business hours.
Charges for LNP Managed Cuts will be based upon the actual hours worked in ½ hour increments multiplied by the number of Qwest personnel actively participating in the cut.
In those situations where Qwest determines a need to manage
a cut, (e.g., the 10-digit unconditional trigger cannot be
set) those LNP Managed Cuts would be scheduled during normal
business hours and there would be no charge. The following
matrix provides examples of when charges apply and when there
is no charge.
| Managed Cut Activity |
(During Normal Business Hours) |
After Qwest normal business hours, Sat. Sun. & Holidays
(Outside Normal Business Hours) |
| You request a LNP Managed Cut |

| Qwest recommends a Managed Cut for more than 2000 Telephone
Numbers and/or more than 200 Trunks |
No Charge |
Charge (you request the cut outside normal business
hours) |
Qwest Customer Service Inquiry and Education (CSIE) hours of operations are described in Wholesale Customer Contacts PCAT.
Qwest will schedule the appropriate number of employees for
the cut, based upon information provided by you during the
coordination meeting. If such information changes and requires
modifications during the cut, and as a result, non-scheduled
employees are required, you will be charged a three-hour minimum
callout per each additional non-scheduled employee. If the
cut is either cancelled, or a supplemental service request is submitted
within 24 hours of the negotiated FDT to change the Due Date
(DD), you will be charged a three-hour minimum.
NOTE: Charges are rounded up. For example, if a LNP Managed
Cut requires 2 hours and 10 minutes, the rates will apply
for five ¸ hour increments, per person.
Charges will be calculated based on actual ½ hours required for the cut, times the number of employees required for each ½ hour of the cut, multiplied by the appropriate rate based on the day and time of the cut. Managed Cuts during Qwest's normal business hours will be charged at a Standard rate. An overtime rate will be charged if the FDT is outside Qwest's normal business hours on Monday through Saturday (excluding holidays). If the FDT is on a Sunday or a Holiday, the charge will be at a Premium rate.
Example: You and Qwest preplan a 10:00 PM cut on a Monday
(outside normal business hours). The cut takes 1¸ hours, and
three Qwest employees participate. The applicable charges
are as follows:
Overtime rate times 3 (people) times 3 (1/2 hour increments) = manual cut charges.

Implementation
Porting Process Overview
When an end-user changes from one service provider to another and wants to retain their TNs, the CLEC who "wins" the end-user will "port" the end-user's number from the former service provider. Coordinated service request activity by the previous and new local service providers removes the end-user's TN from one provider's records and establishes it in the records of the other, establishing the new LRN for call routing purposes. This service request activity is electronically transmitted (uploaded) communicating the new LRN to the administrator of the relevant regional database. This will pair the end-user's original TN with the LRN for the switch of the new CLEC, allowing the end-user to retain the original TN. The regional database administrator (NPAC) will then electronically transmit (download) LRN updates to CLEC-operated Local Service Management System (LSMS). Each CLEC will distribute this information to Service Control Points (SCPs) or Signal Transfer Points (STPs) that CLECs will use to store and process data for routing calls to ported numbers.
Following is a diagram of the basic network elements that are required for all service providers, including CLECs in an LNP environment:
LNP Call Routing Descriptions
To route an interswitch telephone call to a location where number portability is available, determine the LRN for the switch that serves the terminating TN of the call. To determine whether the terminating end-user has ported TN when number portability is available for an NXX, "query" all interswitch calls to that NXX as appropriate. You will accomplish this by sending a signal over the SS7 network to retrieve from a SCP or STP the LRN associated with the called TN.
The FCC has endorsed an "N minus one" (N-1) querying protocol. Under this protocol, if you are the N-1 carrier, you will be responsible for the query, "where 'N" is the entity terminating the call to the end-user, or a network provider contracted by the entity to provide tandem access. Thus the N-1 carrier (i.e., the last carrier before the terminating carrier) for a local call will usually be the billing owner of the call. The N-1 carrier for an interexchange call will usually be the calling end-user's IXC. If you are the N-1 carrier you may perform your own querying, or you may arrange for other carriers or third parties, or for Qwest to provide querying services on your behalf.

North American Numbering Council information is described in the NANC web page.
Location Routing Number (LRN) Trunking, Signaling and Dialing Plans
A LRN looks just like a TN to a switch that is using the
LRN for call routing purposes. It is very important to understand
your signaling requirements and the result of the LERG inputs
to set up your networks appropriately for LNP.
An LRN definition was provided to the industry via the NANC
LNP Architecture and Administrative Plan (Issue 2, Revision
0, April 14, 1998):
"LRNs are 10-digit numbers that are assigned to
the network switching elements (Central Office - Host and
Remotes as required) for routing of calls in the network.
The first six digits of the LRN will be one of the assigned
NPA NXX of the switching element. The purpose and functionality
of the last four digits of the LRN have not yet been defined
but are passed across the network to the terminating switch."
This definition can potentially create some confusion regarding
whether a 7-digit or 10-digit LRN is to be transmitted between
Service Providers for LNP calls. A 7-digit or 10-digit LRN
transmit option will work based on how the participating Service
Providers have set up their trunking and signaling network.
It is vital that Service Providers on both ends of a Trunk
Group understand what is being sent and received. It is also
important to understand that the 7-digit or 10 digits are
counted from right to left.
Technically, an LRN in a signaling message looks just like a TN. The switch uses the LRN for routing purposes, and handles the LRN just like a called party TN. The switch determines where to route a call by the NPA NXX included in the LRN. This routing information provided in Section 4.6 of the LERG determines where and how (signaling) that the NPA NXX should be routed. The LERG input includes the number of digits signaled, whether SS7 or Multi-Frequency (MF), on trunk groups that are used by the complex translations routing group to complete the translations for a particular switch.
Timing and Coordination of Changes in the Local Exchange Routing Guide (LERG) and Switch
Changes that are entered into the LERG, intended for the network, have the potential to affect the end-user's telephone service. When signaling changes are required, it is critical that the timing considerations for LERG changes be fully understood and adhered to, including the Maintenance Window Policy.
Guidelines for timing requirements are described in Central Office Code Assignment Guidelines. You will be able to locate INC Document Number 95-0407-008, Title CO Code (NXX) Assignment Request & Confirmation Form, Part 3. Upon consideration of the timing guidelines, complete this form and submit your LERG changes.
Changes to LRNs also require this same type of planning and
coordination, as well as coordination with the NPAC to perform
routing changes and mass updates. Changes to LRNs may be caused
by various reasons, such as switch replacement, reassignment
of NPA-NXX codes from one service provider to another and/or
NPA splits.
For CLECs, the interfacing company's Service Manager must
be notified of the LERG updates, including 7 to 10-digit,
LRN or other types of changes so they can be scheduled and
coordinated with the Routing Translations groups in both companies.
As a result of this coordination and planning for the minimum
elapsed time, as prescribed in the Industry Guidelines, the
involved Service Providers will be able to make the necessary
changes to their respective networks on the "EFF DTE" shown
in the LERG without disruption of end-user telephone services.
Dialing Plans
The state utilities commission determines dialing plans. The individual service provider determines signaling plan. A signaling plan differs from a dialing plan for a local calling area. The information in the previous section addresses 7-digit or 10-digit LRN Trunk Signaling in the signaling network.
Signaling changes may be required as a result of state-ordered
dialing plan changes. Changes to a signaling network resulting
from dialing plan changes may require coordination between
CLECs, and this coordination is addressed in the ATIS Guideline
referenced above.
Click here to review Dialing
Plans within Qwest territory.
General Dialing Plans within the Qwest territory is described in the Dialing Plans PCAT. Following are examples of some specific Dialing Plans:
| Minneapolis, MN |
Seattle, WA |
Denver, CO |
- Multiple NPAs in the Minneapolis Metropolitan
Statistical Area (MSA); NPAs are geographically assigned
to a particular municipality and there may be multiple
NPAs within a Qwest Rate Center.
- Commission ordered TN porting cannot occur between NPAs.
- If dialing outside of your own NPA, 10-digit dialing
is mandatory but not necessarily a toll call. |
- Multiple NPAs, not overlaid.
- If dialing within your own NPA, 7 digit or 10-digit
dialing is permissive.
- If dialing outside of your own NPA, 10-digit dialing
is mandatory but not necessarily a toll call. - Porting between the NPAs is not permitted. |
- Multiple NPAs; this is an overlay network.
- Porting between NPAs is permitted.
- 10-digit local dialing is mandatory in all cases. |

Product Prerequisites
If you are a new CLEC and are ready to enter the Interconnection
business with Qwest, view Getting
Started as a Facility-Based CLEC or Getting
Started as a Reseller. If you are an existing
CLEC wishing to amend your Interconnection Agreement or your
New Customer Questionnaire, you can find additional information
in the Interconnect Agreement.
The following are actions that must be completed by you prior
to submitting a service request to port a TN:
- Provide after hours contact personnel, who will be responsible
for general problem resolution
- Provide a valid FAX number that is operational Monday-Friday,
5:00 AM to 10:00 PM, Central Time Zone
- Test LSMS and the Service Order Administration (SOA) functions
Establish Signaling System 7 (SS7) Requirements
Your SS7 network must adhere to the industry standards established
for LNP. There are impacts to the Line Information
Data Base (LIDB), Calling Name (CNAM), Custom Local Area Signaling
Service (CLASS™), and Inter-Switched Voice Messaging
services as a result of the industry standards. It is critical
that each company's SS7 technical experts review the requirements
and your specific deployment plans as related to SS7 message
queries. The use of an independent SS7 network and/or SS7
hub provider could introduce additional requirements. If there
is another provider of SS7 service involved, they should be
a part of the requirement review.
Establish E911 Requirements
All Carriers are required by state or municipality to connect
to the E911 network.
This includes specific trunking arrangements, default routing
and data generation. The state or municipality should be contacted
by the CLEC to determine the requirements for the metro area
or state.
All service providers must adhere to the National
Emergency Number Association (NENA) requirements for LNP.
This requires that the Company ID be passed to the E911 database,
along with the Service Provider Company ID and other data
elements from the service request. There is a particular data
structure that is to be followed along with specific function
indicators (Unlock, Migrate, etc.) that are to be used.
Determine Testing Requirements
If you wish to perform testing to ensure that your signaling,
switching, databases, systems and processes are functioning
properly prior to submitting LNP requests, you may want to
contact your Qwest Service Manager.
When contacting Qwest, provide information about your
testing requirements:
- The serving area you plan to test within
- The switch(es) involved in the testing
- How many test numbers you need Qwest to establish and
in what locations
- The timeframe you prefer to do the testing
Also, provide as much information as possible about
the type of testing you intend to perform. For example, are
you planning to:
- Perform call processing tests only, to ensure that your
network and signaling databases are capable of delivering
calls to ported and/or non-ported TNs?
- Perform intra-company tests only, to ensure your switching,
signaling and databases meet the LNP operational requirements
and that you have the systems and processes in place to
accommodate the porting of TNs?
- Perform end-to-end, inter-company testing that includes
submitting service requests to port test TNs between Qwest and your
company?
Once you have provided your initial testing information to
Qwest, your Qwest Sales Executive or Service Manager will
establish a meeting with you to further define your testing
requirements, to identify the key personnel for conducting
the test, from both your company and from Qwest, and to establish
the testing timeline. Additional meetings may need to occur
prior to the testing, and may include identification of test
scripts, if appropriate.
Qwest will initiate service request to establish test accounts,
based on your testing requirements, and will provide information
about the test accounts, including the account name(s), TNs,
and DD of the new connect service request(s). If inter-company
testing is required, critical dates will be jointly established
and may include dates for:
- LSR exchange
- Firm Order Confirmation (FOC) exchange
- Porting of the TN(s)
- Disconnecting test account(s)
During inter-company testing, you will be responsible for:
- Ensuring the subscription is sent to the NPAC
- Verifying activity on subscriptions at the NPAC (i.e.,
T1 and T2 timers)
- Completing the provisioning on your switch for the test
account(s)
- Sending the activation to the NPAC to port the TN(s) on
the requested DD
Upon completion of intra-company testing, you will notify
Qwest that the test accounts may be disconnected. For inter-company
testing, you will need to disconnect the Qwest TNs from your
switch and return them to Qwest, the original code holder.
If test TNs have also been ported from your switch to Qwest,
Qwest will need to disconnect the TNs and return them to you.

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.
Other activities to perform prior to submitting a service request to port a TN are:
- If your request for port activity only addresses the porting of TNs
- Review the end-users Customer Service Record (CSR) verifying all numbers to be ported, including custom ring numbers. All services including alarm services or Exchange Service Extensions, (i.e., Off Premise Extension (OPX) or Different Premise Address (DPA)). when associated with ported TNs, will be disconnected. If you require rearrangement, prior to the port request activity, you and your end-user will contact the appropriate Qwest Department currently servicing the end-user customer to make these changes.
- A reserved number can be identified by the RTNF FID. (e.g., NDNRN/RTNF 111 555-5555)
- If the number you are porting is working a Centrex 21 see the Terms and Conditions section of Resale - Centrex 21.

Ordering
General ordering activities are described in the Ordering Overview.
Ordering standards are developed at the national Ordering
and Billing Forum (OBF).
Local Number Portability service requests are submitted using the following LSOG forms:
- Local Service Request (LSR)
- End User (EU)
- Number Portability (NP) or
- Loop Service with Number Portability (LSNP)
- Directory Listing (DL)
Field entry requirements are described in the LSOG.
The Interconnect Mediated Access (IMA) User Guide specifically details the information available for ordering functions.
Simple Port Request (SPR) service requests are submitted via IMA GUI or XML only using the SPR Form. Field entry requirements for a SPR are described in the LSOG.
Service requests should be placed using Interconnect Mediated Access (IMA) Extensible Markup Language (XML), IMA Graphical User Interface (GUI), or faxed to (888) 796-9089.
If you are requesting NP & LSNP on telephone numbers for the same end user on the same account due the same day, you may request a disconnect of the facilities associated with the NP request on the port date by:
Mark the request for manual handling with a remark to disconnect the facilities on the port date.
If you are requesting LSNP for a telephone number and line that has an associated custom ring number you can:
Issue a separate LSR and enter the custom ring TN in the Ported Number field on the Number Port form. IMA and FTS have been set up to accept the custom ring entry and will automatically place the appropriate port FIDs behind the custom ring USOC as requested.
Or on the LSR for the LSNP drop the request to manual handling and indicate the port request for the custom ring TN in the Remarks field on the LSR.
In all cases you are required to request the port of a custom ring number or it will be disconnected.
If the number(s) you are porting are reserved numbers, the LSR must be issued manually & faxed to Qwest.
When a Qwest account or an account owned by you has Qwest High-Speed Internet (HSI) and you want to change the HSI to a Stand Alone HSI account with a new data TN at the time of port then you need to do the following:
- Populate the Manual indicator field with the letter "Y" and in the Remarks section add "Change HSI to a Stand Alone HSI". NOTE: the same Qwest Stand Alone HSI speed must be available.
Wireless Type 1 service is a non-IMA product and is handled by the Wholesale Service Center. Wireless Type 1 to Wireline or Wireless LNP service requests should be faxed to 877 237-7149. The cover letter should indicate: Attn: Wireless Type 1 Group
When porting DID numbers associated with a VOIP service, this will not be treated as a simple port.
NOTE: The preferred method for submitting VOIP port requests is to utilize the fax gateway to submit these requests. These request(s) must include a Remark indicating that the number(s) being Ported are "associated with a VOIP service".
However, if you attempt to submit these requests through IMA, you must also mark the Manual Handling field of the LSR with a Y and add the Remark indicating that the number(s) being Ported are "associated with a VOIP service".
In addition, either the AN or ATN field of the LSR must be populated with the Telephone Number or Account Number of the End User whose service is being ported.
Hours of Operation
Qwest Customer Service Inquiry and Education (CSIE) telephone numbers and hours of operations are described in Wholesale Customer Contacts
Number Portability Administration Center (NPAC): has defined their standard hours of business for LNP

Directory Listings
You are responsible for contacting a listing service and establishing listings for your end-users.
Qwest has implemented unique entries in the LSR ACT field. To ensure end-user listings are either retained or discontinued one of the following entries is required on the request:
- An ACT entry of “Z” will retain the current listing(s) (Wireline to Wireline LNP only)
- An ACT entry of “V” and no Directory Listing Form(s) will discontinue listings associated with the port activity (all listings are removed; Wireline to Wireline LNP only)
- If you have entered a “V” in the ACT field of the LSR and did not include Directory Listing Form(s) and later wish to establish a new Facilities Based Directory Listing (FBDL) then the LSR, EU and DL forms should be faxed to the Listing Resource Services Managers
- An ACT entry of “V: with Directory Listing Form(s) will allow you to make changes to the Directory Listings. You will be required to complete a Directory Listing form for each listing associated with the new FBDL account. (Wireline to Wireline LNP only)
If the LSR will port only a portion of an account, including the Qwest billing TN, the LSOG forms (LSR, EU, and DL) will be required from you.

Managed Cuts
- LNP Managed Cut Scheduling
Up-front planning and coordination with Qwest is required
to establish the date and time for a LNP Managed Cut. All
requests will be processed on a first come, first served
basis and are subject to Qwest's ability to meet a reasonable
demand. Qwest will coordinate with you for an agreed upon
FDT and FOC
prior to issuing the FOC. Generally the FOC date will not
exceed the standard interval.
- LSR Entries for LNP Managed Cuts
You may request a LNP Managed Cut by submitting a service request
and designating the request as a "Managed Cut" in the Remarks
section of the LSR. Specifically, LNP Managed Cuts
require a notation in the Remarks and DFDT sections of the
LSR, e.g.:
Remarks = Managed Cut
DFDT = Anytime 24x7
When submitting a service request in the IMA GUI or XML, you must
populate the Manual indicator field with the letter "Y".
All negotiated requests must be scheduled on the LNP
Operations schedule in 30-minute time slots.
- CLEC Responsibilities
You will need to schedule
the appropriate personnel for the negotiated FDT for the
LNP Managed Cut. You are also responsible for NPAC coordination
if a Managed Cut is scheduled outside the NPAC's normal
business hours.
